Jonas Jenwald	a5d5b970af	[Firefox addon] Enforce double quotes, using ESLint, to avoid linting errors in mozilla-central (issue 7957) Given that this patch causes a lot of churn in the addon code, I wouldn't really mind if we ultimately decide against doing this and just add a rule exception in mozilla-central instead.[1] --- [1] Note that I used the ESLint `--fix` option, hence writing this commit message actually took longer time than the creation of the patch :-)	8 years ago
Jonas Jenwald	3ec99f0e12	[Firefox addon] Convert the code to be ES6 friendly, in order to better agree with mozilla-central coding conventions (issue 7957) Please note: ignoring whitespace changes is most likely necessary for the diff to be readable. This patch addresses all the current, in `mozilla-central`, linting failures in the addon. It should thus be possible to change the `.eslintignore` entry for PDF.js in `mozilla-central` from `browser/extensions/pdfjs/` to `browser/extensions/pdfjs/build/` and `browser/extensions/pdfjs/web/**` instead. Note that we cannot, for backwards compatibility reason of the general PDF.js library, at this time make similar changes for files residing in the `build` and `web` directories in `mozilla-central`. The main changes in this patch are that we now use [classes](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes) instead of our previous "class-like" functions, and also use the more compact [object shorthand notation](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Object_initializer#New_notations_in_ECMAScript_2015). A couple of functions were also converted to [arrow functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions), to reduced usages of `bind(this)` and `var self = this`. One caveat with ES6 classes is that it's not (yet) possible to define private constants/helper functions within them, which is why the `NetworkManagerClosure` was kept to not change the visibility of those constant/functions. Besides testing in Firefox Nightly 53, this patch has also been tested in Firefox ESR 45 and SeaMonkey 2.46. However, I'd gladly welcome help with testing the patch more, to ensure that nothing has gone wrong during the refactoring. Fixes the first bullet point of issue 7957.	8 years ago
Jonas Jenwald	15f75a5585	[Firefox addon] Remove the `registerAddonHistogram` fallback code for Firefox versions 36 (and below) from `PdfJsTelemetry-addon.jsm` Given that the addon doesn't even work in Firefox versions prior to 38, this is just dead code that can now be removed.	8 years ago
Jonas Jenwald	2f3805efbc	Switch to using ESLint, instead of JSHint, for linting Please note that most of the necessary code adjustments were made in PR 7890. ESLint has a number of advantageous properties, compared to JSHint. Among those are: - The ability to find subtle bugs, thanks to more rules (e.g. PR 7881). - Much more customizable in general, and many rules allow fine-tuned behaviour rather than the just the on/off rules in JSHint. - Many more rules that can help developers avoid bugs, and a lot of rules that can be used to enforce a consistent coding style. The latter should be particularily useful for new contributors (and reduce the amount of stylistic review comments necessary). - The ability to easily specify exactly what rules to use/not to use, as opposed to JSHint which has a default set. Note: in future JSHint version some of the rules we depend on will be removed, according to warnings in http://jshint.com/docs/options/, so we wouldn't be able to update without losing lint coverage. - More easily disable one, or more, rules temporarily. In JSHint this requires using a numeric code, which isn't very user friendly, whereas in ESLint the rule name is simply used instead. By default there's no rules enabled in ESLint, but there are some default rule sets available. However, to prevent linting failures if we update ESLint in the future, it seemed easier to just explicitly specify what rules we want. Obviously this makes the ESLint config file somewhat bigger than the old JSHint config file, but given how rarely that one has been updated over the years I don't think that matters too much. I've tried, to the best of my ability, to ensure that we enable the same rules for ESLint that we had for JSHint. Furthermore, I've also enabled a number of rules that seemed to make sense, both to catch possible errors and various style guide violations. Despite the ESLint README claiming that it's slower that JSHint, https://github.com/eslint/eslint#how-does-eslint-performance-compare-to-jshint, locally this patch actually reduces the runtime for `gulp` lint (by approximately 20-25%). A couple of stylistic rules that would have been nice to enable, but where our code currently differs to much to make it feasible: - `comma-dangle`, controls trailing commas in Objects and Arrays (among others). - `object-curly-spacing`, controls spacing inside of Objects. - `spaced-comment`, used to enforce spaces after `//` and `/*. (This is made difficult by the fact that there's still some usage of the old preprocessor left.) Rules that I indend to look into possibly enabling in follow-ups, if it seems to make sense: `no-else-return`, `no-lonely-if`, `brace-style` with the `allowSingleLine` parameter removed.
