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.

Rob Wu	204d540af2	Handtool: Remove focus from previous node on click "This commit fixes the issue that a focused element cannot lose focus when the draggable element is clicked." https://github.com/Rob--W/grab-to-pan.js/commit/11c368f97cebe19 Steps to reproduce/verify: 1. Enable the hand tool (e.g. by using the H shortcut) 2. Click on the Page number input. 3. Click or drag the PDF canvas. 4. Observe that the page number input is still focused. Consequently, the hand tool cannot be disabled using the H shortcut.	11 years ago
Rob Wu	45c633b072	Update Grab to pan to fix performance issue Reported at http://stackoverflow.com/questions/21392844/pdf-js-recalculating-problme See also `e0f893753a` Changes versus grab-to-pan.js: Moved inline style to viewer.css, lowered z-index from 2e9 to 50000 (note to future maintainers: make sure that all other z-index values stay below 50000!).	11 years ago
Rob Wu	3914768085	Implement hand tool The logic for the hand tool is implemented in a separate project, maintained at https://github.com/Rob--W/grab-to-pan.js Integration notes - Added toggle as an entry under the Secondary toolbar - Added shortcut "h" to toggle hand tool (to-do: document this in wiki after merge). This shortcut is also used in Adobe's Acrobat Reader. To-do: localizations for: hand_tool_enable.title= hand_tool_enable_label= hand_tool_disable.title= hand_tool_disable_label= To-do (wish): persistence of hand tool preference, preferably a global setting. secondaryToolbarButton-handTool.png created by Stephen Horlander <shorlander@mozilla.com>	12 years ago
