Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Rename the `isSpace` helper function to `isWhiteSpace` Trying to enable the ESLint rule `no-shadow`, against the `master` branch, would result in a fair number of errors in the `Glyph` class in `src/core/fonts.js`. Since the glyphs are exposed through the API, we can't very well change the `isSpace` property on `Glyph` instances. Thus the best approach seems, at least to me, to simply rename the `isSpace` helper function to `isWhiteSpace` which shouldn't cause any issues given that it's only used in the `src/core/` folder.

// Unicode Private Use Areas:
Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Use `adjustWidths` for TrueType fonts if we handle them as OpenType (issue 5027, issue 5084, issue 6556, bug 1204903) In `Font_checkAndRepair` we can decide that a font isn't TrueType, and instead parse it as CFF. In that case it's quite possible that the `fontMatrix` will be changed, and without calling `adjustWidths` we're failing to update the glyph widths correctly. Fixes 5027. Fixes 5084. Fixes 6556.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Build a fallback `ToUnicode` map for simple fonts (issue 8229) In some fonts, the included `ToUnicode` data is incomplete causing text-selection to not work properly. For simple fonts that contain encoding data, we can manually build a `ToUnicode` map to attempt to improve things. Please note that since we're currently using the `ToUnicode` data during glyph mapping, in an attempt to avoid rendering regressions, I purposely didn't want to amend to original `ToUnicode` data for this text-selection edge-case. Instead, I opted for the current solution, which will (hopefully) give slightly better text-extraction results in PDF file with incomplete `ToUnicode` data.

Build a fallback `ToUnicode` map for simple fonts (issue 8229) In some fonts, the included `ToUnicode` data is incomplete causing text-selection to not work properly. For simple fonts that contain encoding data, we can manually build a `ToUnicode` map to attempt to improve things. Please note that since we're currently using the `ToUnicode` data during glyph mapping, in an attempt to avoid rendering regressions, I purposely didn't want to amend to original `ToUnicode` data for this text-selection edge-case. Instead, I opted for the current solution, which will (hopefully) give slightly better text-extraction results in PDF file with incomplete `ToUnicode` data. According to the PDF specification, see [section 9.10.2](http://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G8.1873172): > A conforming reader can use these methods, in the priority given, to map a character code to a Unicode value. > ...

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly.

Ensure that TrueType font tables have `uint32` checksums According to "The table directory" under https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6.html#Directory, TrueType font tables should have `uint32` checksums. This is something that I noticed, and was initially confused about, while debugging a TrueType issue. As far as I can tell, the current (`int32`) checksums we use doesn't cause any issues in practice. However, I do think that this should be addressed to agree with the specification, and to reduce possible confusion when reading the font code.

Fix several issues with glyph id mappings. The initial issue with #8255 was I added a missing glyphs check to adjustMapping, but this caused us to skip re-mapping a glyph if the fontCharCode was a missingGlyph which in turn caused us to overwrite a valid glyph id with an invalid one. While fixing this, I also added a warning if the private use area is full since this also accidentally happened when I made a different mistake. This brought to light a number of issues where we map missing glyphs to notdef, but often the notdef is actually defined and then ends up being drawn. Now the glyphs don't get mapped in toFontChar and so they are not drawn by the canvas. Fixing the above brought up another issue though in bug1050040.pdf. In this PDF, the font fails to load by the browser and before we were still drawing the glyphs because it looked like the font had them, but with the fixes above the glyphs showed up as missing so we didn't attempt draw them. To fix this, I now throw an error when the loca table is in really bad shape and we fall back to trying to use a system font. We now also use this fall back if there are any format errors during converting fonts.

On two of those documents I saw improvements of 40 and 50 MiB. The patch also introduces the Glyph constructor, and renames the |unicodeChars| local variable as |unicode| for consistency with the corresponding Glyph property.

Fix several issues with glyph id mappings. The initial issue with #8255 was I added a missing glyphs check to adjustMapping, but this caused us to skip re-mapping a glyph if the fontCharCode was a missingGlyph which in turn caused us to overwrite a valid glyph id with an invalid one. While fixing this, I also added a warning if the private use area is full since this also accidentally happened when I made a different mistake. This brought to light a number of issues where we map missing glyphs to notdef, but often the notdef is actually defined and then ends up being drawn. Now the glyphs don't get mapped in toFontChar and so they are not drawn by the canvas. Fixing the above brought up another issue though in bug1050040.pdf. In this PDF, the font fails to load by the browser and before we were still drawing the glyphs because it looked like the font had them, but with the fixes above the glyphs showed up as missing so we didn't attempt draw them. To fix this, I now throw an error when the loca table is in really bad shape and we fall back to trying to use a system font. We now also use this fall back if there are any format errors during converting fonts.

Enable the `no-nested-ternary` ESLint rule (PR 11488 follow-up) This rule is already enabled in mozilla-central, and helps avoid some confusing formatting, see https://searchfox.org/mozilla-central/rev/9e45d74b956be046e5021a746b0c8912f1c27318/tools/lint/eslint/eslint-plugin-mozilla/lib/configs/recommended.js#209-210 With the recent introduction of Prettier some of the existing nested ternary statements became even more difficult to read, since any possibly helpful indentation was removed. This particular ESLint rule wasn't entirely straightforward to enable, and I do recognize that there's a certain amount of subjectivity in the changes being made. Generally, the changes in this patch fall into three categories: - Cases where a value is only clamped to a certain range (the easiest ones to update). - Cases where the values involved are "simple", such as Numbers and Strings, which are re-factored to initialize the variable with the *default* value and only update it when necessary by using `if`/`else if` statements. - Cases with more complex and/or larger values, such as TypedArrays, which are re-factored to let the variable be (implicitly) undefined and where all values are then set through `if`/`else if`/`else` statements. Please find additional details about the ESLint rule at https://eslint.org/docs/rules/no-nested-ternary

Build a fallback `ToUnicode` map for simple fonts (issue 8229) In some fonts, the included `ToUnicode` data is incomplete causing text-selection to not work properly. For simple fonts that contain encoding data, we can manually build a `ToUnicode` map to attempt to improve things. Please note that since we're currently using the `ToUnicode` data during glyph mapping, in an attempt to avoid rendering regressions, I purposely didn't want to amend to original `ToUnicode` data for this text-selection edge-case. Instead, I opted for the current solution, which will (hopefully) give slightly better text-extraction results in PDF file with incomplete `ToUnicode` data. According to the PDF specification, see [section 9.10.2](http://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G8.1873172): > A conforming reader can use these methods, in the priority given, to map a character code to a Unicode value. > ... Reading that paragraph literally, it doesn't seem too unreasonable to use *different* methods for different charcodes. Fixes 8229.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Parse the font file to determine the correct type/subtype, rather than relying on the (often incorrect) data in the font dictionary The current font type/subtype detection code is quite inconsistent/unwieldy. In some cases it will simply assume that the font dictionary is correct, in others it will somewhat "arbitrarily" check the actual font file (more of these cases have been added over the years to fix specific bugs). As is evident from e.g. issue 9949, the font type/subtype detection code is continuing to cause issues. In an attempt to get rid of these hacks once and for all, this patch instead re-factors the type/subtype detection to *always* parse the font file. Please note that, as far as I can tell, we still appear to need to rely on the composite font detection based on the font dictionary. However, even if the composite/non-composite detection would get it wrong, that shouldn't really matter too much given that there's basically only two different code-paths (for "TrueType-like" vs "Type1-like" fonts).

Use `adjustWidths` for TrueType fonts if we handle them as OpenType (issue 5027, issue 5084, issue 6556, bug 1204903) In `Font_checkAndRepair` we can decide that a font isn't TrueType, and instead parse it as CFF. In that case it's quite possible that the `fontMatrix` will be changed, and without calling `adjustWidths` we're failing to update the glyph widths correctly. Fixes 5027. Fixes 5084. Fixes 6556. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1204903.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Fix several issues with glyph id mappings. The initial issue with #8255 was I added a missing glyphs check to adjustMapping, but this caused us to skip re-mapping a glyph if the fontCharCode was a missingGlyph which in turn caused us to overwrite a valid glyph id with an invalid one. While fixing this, I also added a warning if the private use area is full since this also accidentally happened when I made a different mistake. This brought to light a number of issues where we map missing glyphs to notdef, but often the notdef is actually defined and then ends up being drawn. Now the glyphs don't get mapped in toFontChar and so they are not drawn by the canvas. Fixing the above brought up another issue though in bug1050040.pdf. In this PDF, the font fails to load by the browser and before we were still drawing the glyphs because it looked like the font had them, but with the fixes above the glyphs showed up as missing so we didn't attempt draw them.

Enable the `no-nested-ternary` ESLint rule (PR 11488 follow-up) This rule is already enabled in mozilla-central, and helps avoid some confusing formatting, see https://searchfox.org/mozilla-central/rev/9e45d74b956be046e5021a746b0c8912f1c27318/tools/lint/eslint/eslint-plugin-mozilla/lib/configs/recommended.js#209-210 With the recent introduction of Prettier some of the existing nested ternary statements became even more difficult to read, since any possibly helpful indentation was removed. This particular ESLint rule wasn't entirely straightforward to enable, and I do recognize that there's a certain amount of subjectivity in the changes being made. Generally, the changes in this patch fall into three categories: - Cases where a value is only clamped to a certain range (the easiest ones to update). - Cases where the values involved are "simple", such as Numbers and Strings, which are re-factored to initialize the variable with the *default* value and only update it when necessary by using `if`/`else if` statements. - Cases with more complex and/or larger values, such as TypedArrays, which are re-factored to let the variable be (implicitly) undefined and where all values are then set through `if`/`else if`/`else` statements. Please find additional details about the ESLint rule at https://eslint.org/docs/rules/no-nested-ternary

Add a (basic) `isCFFFile` helper function to detect CFF font files Compared to most other font formats, the CFF doesn't have a constant header which makes is slightly more difficult to detect such font files. Please refer to the Compact Font Format specification: https://www.adobe.com/content/dam/acom/en/devnet/font/pdfs/5176.CFF.pdf#G3.32094

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Parse the font file to determine the correct type/subtype, rather than relying on the (often incorrect) data in the font dictionary The current font type/subtype detection code is quite inconsistent/unwieldy. In some cases it will simply assume that the font dictionary is correct, in others it will somewhat "arbitrarily" check the actual font file (more of these cases have been added over the years to fix specific bugs). As is evident from e.g. issue 9949, the font type/subtype detection code is continuing to cause issues. In an attempt to get rid of these hacks once and for all, this patch instead re-factors the type/subtype detection to *always* parse the font file. Please note that, as far as I can tell, we still appear to need to rely on the composite font detection based on the font dictionary. However, even if the composite/non-composite detection would get it wrong, that shouldn't really matter too much given that there's basically only two different code-paths (for "TrueType-like" vs "Type1-like" fonts).

Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Consistently use `@returns` for returned data types in JSDoc comments Sometimes we also used `@return`, but `@returns` is what the JSDoc documentation recommends. Even though `@return` works as an alias, it's good to use the recommended syntax and to be consistent within the project.

Fix several issues with glyph id mappings. The initial issue with #8255 was I added a missing glyphs check to adjustMapping, but this caused us to skip re-mapping a glyph if the fontCharCode was a missingGlyph which in turn caused us to overwrite a valid glyph id with an invalid one. While fixing this, I also added a warning if the private use area is full since this also accidentally happened when I made a different mistake. This brought to light a number of issues where we map missing glyphs to notdef, but often the notdef is actually defined and then ends up being drawn. Now the glyphs don't get mapped in toFontChar and so they are not drawn by the canvas. Fixing the above brought up another issue though in bug1050040.pdf. In this PDF, the font fails to load by the browser and before we were still drawing the glyphs because it looked like the font had them, but with the fixes above the glyphs showed up as missing so we didn't attempt draw them. To fix this, I now throw an error when the loca table is in really bad shape and we fall back to trying to use a system font. We now also use this fall back if there are any format errors during converting fonts.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Adjust the `brace-style` ESLint rule to disallow single lines (and also enable `no-iterator`) See http://eslint.org/docs/rules/brace-style. Having the opening/closing braces on the same line can often make the code slightly more difficult to read, in particular for `if`/`else if` statements, compared to using new lines. This patch also, for consistency with `mozilla-central`, enables the [`no-iterator`](http://eslint.org/docs/rules/no-iterator) rule. Note that this rule didn't require a single code change.

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead.

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Fallback to the built-in font renderer when font loading fails After PR 9340 all glyphs are now re-mapped to a Private Use Area (PUA) which means that if a font fails to load, for whatever reason[1], all glyphs in the font will now render as Unicode glyph outlines. This obviously doesn't look good, to say the least, and might be seen as a "regression" since previously many glyphs were left in their original positions which provided a slightly better fallback[2]. Hence this patch, which implements a *general* fallback to the PDF.js built-in font renderer for fonts that fail to load (i.e. are rejected by the sanitizer). One caveat here is that this only works for the Font Loading API, since it's easy to handle errors in that case[3]. The solution implemented in this patch does *not* in any way delay the loading of valid fonts, which was the problem with my previous attempt at a solution, and will only require a bit of extra work/waiting for those fonts that actually fail to load. *Please note:* This patch doesn't fix any of the underlying PDF.js font conversion bugs that's responsible for creating corrupt font files, however it does *improve* rendering in a number of cases; refer to this possibly incomplete list: [Bug 1524888](https://bugzilla.mozilla.org/show_bug.cgi?id=1524888) Issue 10175 Issue 10232 --- [1] Usually because the PDF.js font conversion code wasn't able to parse the font file correctly. [2] Glyphs fell back to some default font, which while not accurate was more useful than the current state. [3] Furthermore I'm not sure how to implement this generally, assuming that's even possible, and don't really have time/interest to look into it either.

Fix several issues with glyph id mappings. The initial issue with #8255 was I added a missing glyphs check to adjustMapping, but this caused us to skip re-mapping a glyph if the fontCharCode was a missingGlyph which in turn caused us to overwrite a valid glyph id with an invalid one. While fixing this, I also added a warning if the private use area is full since this also accidentally happened when I made a different mistake. This brought to light a number of issues where we map missing glyphs to notdef, but often the notdef is actually defined and then ends up being drawn. Now the glyphs don't get mapped in toFontChar and so they are not drawn by the canvas. Fixing the above brought up another issue though in bug1050040.pdf. In this PDF, the font fails to load by the browser and before we were still drawing the glyphs because it looked like the font had them, but with the fixes above the glyphs showed up as missing so we didn't attempt draw them. To fix this, I now throw an error when the loca table is in really bad shape and we fall back to trying to use a system font. We now also use this fall back if there are any format errors during converting fonts.

Add basic support for non-embedded Calibri fonts (issue 9195) There's a number of issues with the fonts in the referenced PDF file. First of all, they contain broken `ToUnicode` data (`NUL` bytes all over the place). However even if you skip those, the `ToUnicode` data appears to contain nothing but a `IdentityH` CMap which won't help provide a proper glyph mapping. The real issue actually turns out to be that the PDF file uses the "Calibri" font[1], but doesn't include any font files. Since that one isn't a standard font, and uses a fairly different CID to GID map compared to the standard fonts, we're not able to render the file even remotely correct. To work around this, I'm thus proposing that we include a (incomplete) glyph map for Calibri, and fallback to the standard Helvetica font. Obviously this isn't going to look perfect, but it's really the best that we can hope to achieve given that the PDF file is missing the necessary font data. Finally, please note that none of the PDF readers I've tried (Adobe Reader, PDFium in Chrome) were able to extract the text (which isn't very surprising, given the broken `ToUnicode` data). Fixes 9195. --- [1] According to Wikipedia, see https://en.wikipedia.org/wiki/Calibri, Calibri is (primarily) a Windows font.

It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly.

Fix several issues with glyph id mappings. The initial issue with #8255 was I added a missing glyphs check to adjustMapping, but this caused us to skip re-mapping a glyph if the fontCharCode was a missingGlyph which in turn caused us to overwrite a valid glyph id with an invalid one. While fixing this, I also added a warning if the private use area is full since this also accidentally happened when I made a different mistake. This brought to light a number of issues where we map missing glyphs to notdef, but often the notdef is actually defined and then ends up being drawn. Now the glyphs don't get mapped in toFontChar and so they are not drawn by the canvas. Fixing the above brought up another issue though in bug1050040.pdf. In this PDF, the font fails to load by the browser and before we were still drawing the glyphs because it looked like the font had them, but with the fixes above the glyphs showed up as missing so we didn't attempt draw them. To fix this, I now throw an error when the loca table is in really bad shape and we fall back to trying to use a system font. We now also use this fall back if there are any format errors during converting fonts.

Ensure that TrueType font tables have `uint32` checksums According to "The table directory" under https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6.html#Directory, TrueType font tables should have `uint32` checksums. This is something that I noticed, and was initially confused about, while debugging a TrueType issue. As far as I can tell, the current (`int32`) checksums we use doesn't cause any issues in practice. However, I do think that this should be addressed to agree with the specification, and to reduce possible confusion when reading the font code.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

/**
* Read the appropriate subtable from the cmap according to 9.6.6.4 from
* PDF spec
*/
Only choose a (3, 1) cmap table for TrueType fonts that have an encoding specified (issue 6410) For (1, 0) cmaps, we have two different codepaths depending on whether the font has/hasn't got an encoding. But with (3, 1) cmaps we don't have a good fallback when the encoding is missing, hence this patch changes `readCmapTable` to only choose a (3, 1) cmap table if the font is non-symbolic *and* an encoding exists. Without this, we'll not be able to successfully create a working glyph map for some TrueType fonts with (3, 1) cmap tables. Fixes 6410.

Enable the `no-unused-vars` ESLint rule Please see http://eslint.org/docs/rules/no-unused-vars; note that this patch purposely uses the same rule options as in `mozilla-central`, such that it fixes part of issue 7957. It wasn't, in my opinion, entirely straightforward to enable this rule compared to the already existing rules. In many cases a `var descriptiveName = ...` format was used (more or less) to document the code, and I choose to place the old variable name in a trailing comment to not lose that information. I welcome feedback on these changes, since it wasn't always entirely easy to know what changes made the most sense in every situation.

Fix two cmap related issues. In issue #8707, there's a char code mapped to a non- existing glyph which shouldn't be drawn. However, we saw it was missing and tried to then use the post table and end up mapping it incorrectly. This illuminated a problem with issue #5704 and bug 893730 where glyphs disappeared after above fix. This was from the cmap returning the wrong glyph id. Which in turn was caused because the font had multiple of the same type of cmap table and we were choosing the last one. Now, we instead default to the first one. I'm unsure if we should instead be merging the multiple cmaps, but using only the first one works.

Enable the `no-unused-vars` ESLint rule Please see http://eslint.org/docs/rules/no-unused-vars; note that this patch purposely uses the same rule options as in `mozilla-central`, such that it fixes part of issue 7957. It wasn't, in my opinion, entirely straightforward to enable this rule compared to the already existing rules. In many cases a `var descriptiveName = ...` format was used (more or less) to document the code, and I choose to place the old variable name in a trailing comment to not lose that information. I welcome feedback on these changes, since it wasn't always entirely easy to know what changes made the most sense in every situation.

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead. Please note: This patch was created automatically, using the ESLint --fix command line option.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Fallback in `readCmapTable`, instead of using `error`, for TrueType fonts with unsupported cmap formats (bug 1200096) Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1200096. The problematic font has a `format 2` cmap, which we've never supported properly. Prior to PR 2606, we were able to fallback to a working state, despite not having proper support for that cmap format. Obviously the best/correct solution would be to implement actual support for more cmap formats[1]. However, I'm hoping that a simple patch will be OK for now, given that: - `format 2` cmaps seem to be quite rare in practice, since this has been broken for 2.5 years before anyone noticed. - Having a simple patch will make potential uplifts a lot easier.

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Enable the `no-nested-ternary` ESLint rule (PR 11488 follow-up) This rule is already enabled in mozilla-central, and helps avoid some confusing formatting, see https://searchfox.org/mozilla-central/rev/9e45d74b956be046e5021a746b0c8912f1c27318/tools/lint/eslint/eslint-plugin-mozilla/lib/configs/recommended.js#209-210 With the recent introduction of Prettier some of the existing nested ternary statements became even more difficult to read, since any possibly helpful indentation was removed. This particular ESLint rule wasn't entirely straightforward to enable, and I do recognize that there's a certain amount of subjectivity in the changes being made. Generally, the changes in this patch fall into three categories: - Cases where a value is only clamped to a certain range (the easiest ones to update). - Cases where the values involved are "simple", such as Numbers and Strings, which are re-factored to initialize the variable with the *default* value and only update it when necessary by using `if`/`else if` statements. - Cases with more complex and/or larger values, such as TypedArrays, which are re-factored to let the variable be (implicitly) undefined and where all values are then set through `if`/`else if`/`else` statements. Please find additional details about the ESLint rule at https://eslint.org/docs/rules/no-nested-ternary

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode.

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly.

Fall back to the |defaultEncoding| when no valid "post" table is found in TrueType fonts (bug 1050040) Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1050040. With this patch the file is completely readable, but given that the font is broken enough to be rejected by OTS the rendering differs slightly from Adobe Reader. *Note:* the PDF file is sufficiently broken that even Adobe Reader complains about the font, *and* also about another more general issue.

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead.

Avoid accidentally getting the entire font file in `readNameTable` (issue 7020) In the PDF file in question, some of the 'name' table entries have `record.length === 0`. This becomes problematic in the non-unicode case, since `font.getBytes(0)` will fetch the *entire* stream. Given that OTS rejects 'name' entries larger than `2^16`, this thus explain the sanitizer errors. Fixes 7020.

Add `// prettier-ignore` comments to prevent re-formatting of certain data structures There's a fair number of (primarily) `Array`s/`TypedArray`s whose formatting we don't want disturb, since in many cases that would lead to the code becoming much more difficult to read and/or break existing inline comments. *Please note:* It may be a good idea to look through these cases individually, and possibly re-write some of the them (especially the `String` ones) to reduce the need for all of these ignore commands.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Enable the `no-nested-ternary` ESLint rule (PR 11488 follow-up) This rule is already enabled in mozilla-central, and helps avoid some confusing formatting, see https://searchfox.org/mozilla-central/rev/9e45d74b956be046e5021a746b0c8912f1c27318/tools/lint/eslint/eslint-plugin-mozilla/lib/configs/recommended.js#209-210 With the recent introduction of Prettier some of the existing nested ternary statements became even more difficult to read, since any possibly helpful indentation was removed. This particular ESLint rule wasn't entirely straightforward to enable, and I do recognize that there's a certain amount of subjectivity in the changes being made. Generally, the changes in this patch fall into three categories: - Cases where a value is only clamped to a certain range (the easiest ones to update). - Cases where the values involved are "simple", such as Numbers and Strings, which are re-factored to initialize the variable with the *default* value and only update it when necessary by using `if`/`else if` statements. - Cases with more complex and/or larger values, such as TypedArrays, which are re-factored to let the variable be (implicitly) undefined and where all values are then set through `if`/`else if`/`else` statements. Please find additional details about the ESLint rule at https://eslint.org/docs/rules/no-nested-ternary

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead. Please note: This patch was created automatically, using the ESLint --fix command line option.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

[TrueType] Recover from a missing "glyf" table by replacing it with dummy data, utilizing the existing code in `sanitizeGlyphLocations` It seems to be fairly common for OCR software to include incomplete TrueType fonts, notable missing the "glyf" table, in PDF files. Since we currently reject such fonts, the result is that text-selection/copying is broken. This patch contains a suggested approach to try and use these kind of broken fonts, by using existing code in `sanitizeGlyphLocations` to replace a missing "glyf" table with dummy data. Fixes 4684. Fixes 6007. Fixes 6829.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters.

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Fix two cmap related issues. In issue #8707, there's a char code mapped to a non- existing glyph which shouldn't be drawn. However, we saw it was missing and tried to then use the post table and end up mapping it incorrectly. This illuminated a problem with issue #5704 and bug 893730 where glyphs disappeared after above fix. This was from the cmap returning the wrong glyph id. Which in turn was caused because the font had multiple of the same type of cmap table and we were choosing the last one. Now, we instead default to the first one. I'm unsure if we should instead be merging the multiple cmaps, but using only the first one works.

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead. Please note: This patch was created automatically, using the ESLint --fix command line option. In a couple of places this caused lines to become too long, and I've fixed those manually; please refer to the interdiff below for the only hand-edits in this patch. ```diff diff --git a/src/core/evaluator.js b/src/core/evaluator.js index abab9027..dcd3594b 100644 --- a/src/core/evaluator.js +++ b/src/core/evaluator.js @@ -2785,7 +2785,8 @@ var EvaluatorPreprocessor = (function EvaluatorPreprocessorClosure() { t['Tz'] = { id: OPS.setHScale, numArgs: 1, variableArgs: false, }; t['TL'] = { id: OPS.setLeading, numArgs: 1, variableArgs: false, }; t['Tf'] = { id: OPS.setFont, numArgs: 2, variableArgs: false, }; - t['Tr'] = { id: OPS.setTextRenderingMode, numArgs: 1, variableArgs: false, }; + t['Tr'] = { id: OPS.setTextRenderingMode, numArgs: 1, + variableArgs: false, }; t['Ts'] = { id: OPS.setTextRise, numArgs: 1, variableArgs: false, }; t['Td'] = { id: OPS.moveText, numArgs: 2, variableArgs: false, }; t['TD'] = { id: OPS.setLeadingMoveText, numArgs: 2, variableArgs: false, }; diff --git a/src/core/jbig2.js b/src/core/jbig2.js index 5a17d482..71671541 100644 --- a/src/core/jbig2.js +++ b/src/core/jbig2.js @@ -123,19 +123,22 @@ var Jbig2Image = (function Jbig2ImageClosure() { { x: -1, y: -1, }, { x: 0, y: -1, }, { x: 1, y: -1, }, { x: -2, y: 0, }, { x: -1, y: 0, }], [{ x: -3, y: -1, }, { x: -2, y: -1, }, { x: -1, y: -1, }, { x: 0, y: -1, }, - { x: 1, y: -1, }, { x: -4, y: 0, }, { x: -3, y: 0, }, { x: -2, y: 0, }, { x: -1, y: 0, }] + { x: 1, y: -1, }, { x: -4, y: 0, }, { x: -3, y: 0, }, { x: -2, y: 0, }, + { x: -1, y: 0, }] ]; var RefinementTemplates = [ { coding: [{ x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }], - reference: [{ x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }, { x: 0, y: 0, }, - { x: 1, y: 0, }, { x: -1, y: 1, }, { x: 0, y: 1, }, { x: 1, y: 1, }], + reference: [{ x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }, + { x: 0, y: 0, }, { x: 1, y: 0, }, { x: -1, y: 1, }, + { x: 0, y: 1, }, { x: 1, y: 1, }], }, { - coding: [{ x: -1, y: -1, }, { x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }], - reference: [{ x: 0, y: -1, }, { x: -1, y: 0, }, { x: 0, y: 0, }, { x: 1, y: 0, }, - { x: 0, y: 1, }, { x: 1, y: 1, }], + coding: [{ x: -1, y: -1, }, { x: 0, y: -1, }, { x: 1, y: -1, }, + { x: -1, y: 0, }], + reference: [{ x: 0, y: -1, }, { x: -1, y: 0, }, { x: 0, y: 0, }, + { x: 1, y: 0, }, { x: 0, y: 1, }, { x: 1, y: 1, }], } ]; ```

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Fix the `charCodeOf` method in `IdentityToUnicodeMap` in order to prevent text selection from breaking After PR 6590, `font.spaceWidth` is now called in more cases than before (in `PartialEvaluator_getTextContent`), which exposed an underlying issue with `IdentityToUnicodeMap_charCodeOf` throwing an error.

Add a cache for glyphs. This reduces memory consumption for text heavy documents. I tested five documents and saw hit rates ranging from 97.4% to 99.8% (most of the misses are due to |width| varying even when |fontChar| matches). On two of those documents I saw improvements of 40 and 50 MiB. The patch also introduces the Glyph constructor, and renames the |unicodeChars| local variable as |unicode| for consistency with the corresponding Glyph property.

Hide .notdef glyphs in non-embedded Type1 fonts and don't ignore Widths Fixes #11403 The PDF uses the non-embedded Type1 font Helvetica. Character codes 194 and 160 (`Â` and `NBSP`) are encoded as `.notdef`. We shouldn't show those glyphs because it seems that Acrobat Reader doesn't draw glyphs that are named `.notdef` in fonts like this. In addition to testing `glyphName === ".notdef"`, we must test also `glyphName === ""` because the name `""` is used in `core/encodings.js` for undefined glyphs in encodings like `WinAnsiEncoding`. The solution above hides the `Â` characters but now the replacement character (space) appears to be too wide. I found out that PDF.js ignores font's `Widths` array if the font has no `FontDescriptor` entry. That happens in #11403, so the default widths of Helvetica were used as specified in `core/metrics.js` and `.nodef` got a width of 333. The correct width is 0 as specified by the `Widths` array in the PDF. Thus we must never ignore `Widths`.

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Add a cache for glyphs. This reduces memory consumption for text heavy documents. I tested five documents and saw hit rates ranging from 97.4% to 99.8% (most of the misses are due to |width| varying even when |fontChar| matches). On two of those documents I saw improvements of 40 and 50 MiB. The patch also introduces the Glyph constructor, and renames the |unicodeChars| local variable as |unicode| for consistency with the corresponding Glyph property.

Fallback to the built-in font renderer when font loading fails After PR 9340 all glyphs are now re-mapped to a Private Use Area (PUA) which means that if a font fails to load, for whatever reason[1], all glyphs in the font will now render as Unicode glyph outlines. This obviously doesn't look good, to say the least, and might be seen as a "regression" since previously many glyphs were left in their original positions which provided a slightly better fallback[2]. Hence this patch, which implements a *general* fallback to the PDF.js built-in font renderer for fonts that fail to load (i.e. are rejected by the sanitizer). One caveat here is that this only works for the Font Loading API, since it's easy to handle errors in that case[3]. The solution implemented in this patch does *not* in any way delay the loading of valid fonts, which was the problem with my previous attempt at a solution, and will only require a bit of extra work/waiting for those fonts that actually fail to load. *Please note:* This patch doesn't fix any of the underlying PDF.js font conversion bugs that's responsible for creating corrupt font files, however it does *improve* rendering in a number of cases; refer to this possibly incomplete list: [Bug 1524888](https://bugzilla.mozilla.org/show_bug.cgi?id=1524888) Issue 10175 Issue 10232 --- [1] Usually because the PDF.js font conversion code wasn't able to parse the font file correctly. [2] Glyphs fell back to some default font, which while not accurate was more useful than the current state. [3] Furthermore I'm not sure how to implement this generally, assuming that's even possible, and don't really have time/interest to look into it either.

This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead.

Rename the `isSpace` helper function to `isWhiteSpace` Trying to enable the ESLint rule `no-shadow`, against the `master` branch, would result in a fair number of errors in the `Glyph` class in `src/core/fonts.js`. Since the glyphs are exposed through the API, we can't very well change the `isSpace` property on `Glyph` instances. Thus the best approach seems, at least to me, to simply rename the `isSpace` helper function to `isWhiteSpace` which shouldn't cause any issues given that it's only used in the `src/core/` folder.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Enable auto-formatting of the entire code-base using Prettier (issue 11444) Note that Prettier, purposely, has only limited [configuration options](https://prettier.io/docs/en/options.html). The configuration file is based on [the one in `mozilla central`](https://searchfox.org/mozilla-central/source/.prettierrc) with just a few additions (to avoid future breakage if the defaults ever changes). Prettier is being used for a couple of reasons: - To be consistent with `mozilla-central`, where Prettier is already in use across the tree. - To ensure a *consistent* coding style everywhere, which is automatically enforced during linting (since Prettier is used as an ESLint plugin). This thus ends "all" formatting disussions once and for all, removing the need for review comments on most stylistic matters. Many ESLint options are now redundant, and I've tried my best to remove all the now unnecessary options (but I may have missed some). Note also that since Prettier considers the `printWidth` option as a guide, rather than a hard rule, this patch resorts to a small hack in the ESLint config to ensure that *comments* won't become too long. *Please note:* This patch is generated automatically, by appending the `--fix` argument to the ESLint call used in the `gulp lint` task. It will thus require some additional clean-up, which will be done in a *separate* commit. (On a more personal note, I'll readily admit that some of the changes Prettier makes are *extremely* ugly. However, in the name of consistency we'll probably have to live with that.)

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.

Represent cid chars using integers, not strings. cid chars are 16-bit unsigned integers. Currently we convert them to single-char strings when inserting them into the CMap, and then convert them back to integers when extracting them from the CMap. This patch changes CMap so that cid chars stay in integer format throughout, saving both time and space. When loading the PDF from issue #4580, this change reduces peak RSS from ~600 to ~370 MiB. It also improves overall speed on that PDF by ~26%, going from 724 ms to 533 ms.

Fix inconsistent spacing and trailing commas in objects in `src/core/` files, so we can enable the `comma-dangle` and `object-curly-spacing` ESLint rules later on *Unfortunately this patch is fairly big, even though it only covers the `src/core` folder, but splitting it even further seemed difficult.* http://eslint.org/docs/rules/comma-dangle http://eslint.org/docs/rules/object-curly-spacing Given that we currently have quite inconsistent object formatting, fixing this in *one* big patch probably wouldn't be feasible (since I cannot imagine anyone wanting to review that); hence I've opted to try and do this piecewise instead. Please note: This patch was created automatically, using the ESLint --fix command line option. In a couple of places this caused lines to become too long, and I've fixed those manually; please refer to the interdiff below for the only hand-edits in this patch. ```diff diff --git a/src/core/evaluator.js b/src/core/evaluator.js index abab9027..dcd3594b 100644 --- a/src/core/evaluator.js +++ b/src/core/evaluator.js @@ -2785,7 +2785,8 @@ var EvaluatorPreprocessor = (function EvaluatorPreprocessorClosure() { t['Tz'] = { id: OPS.setHScale, numArgs: 1, variableArgs: false, }; t['TL'] = { id: OPS.setLeading, numArgs: 1, variableArgs: false, }; t['Tf'] = { id: OPS.setFont, numArgs: 2, variableArgs: false, }; - t['Tr'] = { id: OPS.setTextRenderingMode, numArgs: 1, variableArgs: false, }; + t['Tr'] = { id: OPS.setTextRenderingMode, numArgs: 1, + variableArgs: false, }; t['Ts'] = { id: OPS.setTextRise, numArgs: 1, variableArgs: false, }; t['Td'] = { id: OPS.moveText, numArgs: 2, variableArgs: false, }; t['TD'] = { id: OPS.setLeadingMoveText, numArgs: 2, variableArgs: false, }; diff --git a/src/core/jbig2.js b/src/core/jbig2.js index 5a17d482..71671541 100644 --- a/src/core/jbig2.js +++ b/src/core/jbig2.js @@ -123,19 +123,22 @@ var Jbig2Image = (function Jbig2ImageClosure() { { x: -1, y: -1, }, { x: 0, y: -1, }, { x: 1, y: -1, }, { x: -2, y: 0, }, { x: -1, y: 0, }], [{ x: -3, y: -1, }, { x: -2, y: -1, }, { x: -1, y: -1, }, { x: 0, y: -1, }, - { x: 1, y: -1, }, { x: -4, y: 0, }, { x: -3, y: 0, }, { x: -2, y: 0, }, { x: -1, y: 0, }] + { x: 1, y: -1, }, { x: -4, y: 0, }, { x: -3, y: 0, }, { x: -2, y: 0, }, + { x: -1, y: 0, }] ]; var RefinementTemplates = [ { coding: [{ x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }], - reference: [{ x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }, { x: 0, y: 0, }, - { x: 1, y: 0, }, { x: -1, y: 1, }, { x: 0, y: 1, }, { x: 1, y: 1, }], + reference: [{ x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }, + { x: 0, y: 0, }, { x: 1, y: 0, }, { x: -1, y: 1, }, + { x: 0, y: 1, }, { x: 1, y: 1, }], }, { - coding: [{ x: -1, y: -1, }, { x: 0, y: -1, }, { x: 1, y: -1, }, { x: -1, y: 0, }], - reference: [{ x: 0, y: -1, }, { x: -1, y: 0, }, { x: 0, y: 0, }, { x: 1, y: 0, }, - { x: 0, y: 1, }, { x: 1, y: 1, }], + coding: [{ x: -1, y: -1, }, { x: 0, y: -1, }, { x: 1, y: -1, }, + { x: -1, y: 0, }], + reference: [{ x: 0, y: -1, }, { x: -1, y: 0, }, { x: 0, y: 0, }, + { x: 1, y: 0, }, { x: 0, y: 1, }, { x: 1, y: 1, }], } ]; ```

Map all glyphs to the private use area and duplicate the first glyph. There have been lots of problems with trying to map glyphs to their unicode values. It's more reliable to just use the private use areas so the browser's font renderer doesn't mess with the glyphs. Using the private use area for all glyphs did highlight other issues that this patch also had to fix: * small private use area - Previously, only the BMP private use area was used which can't map many glyphs. Now, the (much bigger) PUP 16 area can also be used. * glyph zero not shown - Browsers will not use the glyph from a font if it is glyph id = 0. This issue was less prevalent when we mapped to unicode values since the fallback font would be used. However, when using the private use area, the glyph would not be drawn at all. This is illustrated in one of the current test cases (issue #8234) where there's an "ä" glyph at position zero. The PDF looked like it rendered correctly, but it was actually not using the glyph from the font. To properly show the first glyph it is always duplicated and appended to the glyphs and the maps are adjusted. * supplementary characters - The private use area PUP 16 is 4 bytes, so String.fromCodePoint must be used where we previously used String.fromCharCode. This is actually an issue that should have been fixed regardless of this patch. * charset - Freetype fails to load fonts when the charset size doesn't match number of glyphs in the font. We now write out a fake charset with the correct length. This also brought up the issue that glyphs with seac/endchar should only ever write a standard charset, but we now write a custom one. To get around this the seac analysis is permanently enabled so those glyphs are instead always drawn as two glyphs.
