* Check for undefined
new URL(file, window.location.href) throws the following error in IE11 + iPad Safari:
Unable to get property 'replace' of undefined or null reference
* Adapting previous change to pdf.js code standards
Added curly braces
* Moved check for undefined above try/catch
`__pdfjsdev_webpack__` was used to skip evaluating part of an AST,
in order to not mangle some `require` symbols.
This commit removes `__pdfjsdev_webpack__`, and:
- Uses `__non_webpack_require__` when one wants the output to
contain `require` instead of `__webpack_require__`.
- Adds options to the webpack config to prevent "polyfills" for
some Node.js-specific APIs to be added.
- Use `// eslint-disable-next-line no-undef` instead of `/* globals ... */`
for variables that are not meant to be used globally.
Don't allow setting various properties, such as `currentPageNumber`/`currentScale`/`currentScaleValue`/`pagesRotation`, before `{PDFViewer, PDFThumbnailViewer}.setDocument` has been called
This is a trivial follow-up to PR 5383, and it's a bit strange that this has been wrong since late 2014 without anyone noticing (maybe because inline images aren't too common).
So, apparently code works better if you actually spell correctly, who knew ;-)
Fixes 8613.
Note that these files were among the first to be converted to ES6 classes, so it probably makes sense to do another pass to bring them inline with the most recent ES6 conversions.
All other code-paths already checks that the `MessageHandler` isn't terminated, but apparently `onFailure` was missing that check (compare e.g. with the `onSuccess` function).
From what I can tell, this is only an issue if workers are *disabled*, hence why I didn't bother adding a unit-test.
Fixes 8584.
These changes consists mainly of replacing `var` with `let`/`const`, adding a couple of default parameters to function signatures, and finally converting `EventBus`/`ProgressBar` to proper classes.
After PR 8510, we now always lookup the localized `page_scale_percent` string to prevent any possible ordering issues. Since the scaleSelect dropdown is updated asynchronous, there's really no point in having a helper function any more, hence this code can rather be placed inline in `Toolbar._updateUIState`.
In general, we may not know the stroke properties when path construction
happens. Since we must know the properties when we apply the stroke, we
should set the properties at that point. Note that we already do that
for the color and opacity, but not yet for the other properties.
The https://github.com/mozilla/pdf.js/wiki/Contributing article has been updated to explicitly mention that an ES6 browser is now a minimum requirement for development.
Since we recently have seen a couple of issues filed which seemed to indicate that people tried to use PDF.js in browsers without full ES6 support, it's probably a good idea to mention this more prominently in the README as well.
