* Add Tooltip component to common
Will be used to provide backwards compatibility when we switch to CSS tooltips.
All other methods of creating tooltips are deprecated and this component-based method should be used instead.
* Modify direct child instead of using container element
Instead of using a container to house the tooltip, we'll now modify the
first direct child of the Tooltip component.
The Tooltip component will ensure that:
- children are passed to it
- only one child is present
- that child is an actual HTML Element and not a text node, or similar
- that child is currently present in the DOM
Only after all of the above are satisfied, will the tooltip be created
on that element. We store a reference to the DOM node that the tooltip
should be created on, then use this to perform tooltip actions via
jQuery. If this element gets changes (e.g. the tooltip content is
updated to another element) then the tooltip will be recreated.
If any of the first 3 requirements are not satisfied, an error will
be thrown to alert the developer to their misuse of this component.
To make this work, we do need to overwrite the title attribute of
the element with the tooltip, but this is the only solution other than
specifying `title` as an option when making the tooltip, but this is
not accessible by screenreaders unless they simulate a hover on the
element.
* Add warning about component overwriting `title` attr
* Update previous uses of Tooltip component
* Remove `lodash-es` dependency
* Replace `escapeRegExp` with home-made util
* Replace `throttle` with `throttle-debounce` library
* Use native browser methods for `deepFlatten`
We need a polyfill for iOS 11 and below. I think using a native method with this polyfill is better than having our own function instead, even if the bundle size is ~150B more.
* Save a few bytes in `escapeRegExp`
* Fix typo in comment
* Undo import re-organisation
* Use spread instead of slice
* Use smaller Array.flat polyfill from MDN
* Export new utils in `compat.js`
* Bump dependencies and add missing typing libraries
* Fix expose-loader breaking changes
* Expose jQuery using its own typings instead of ours
* Extend jQuery typings with our own custom $.fn helpers
* Use jQuery typings for Component's `this.$` attribute
* Format webpack config file
* Use Spin.js 3.1.0
We previously used the tobscure/m.attrs.bidi github repo, but that repo was recently taken offline. We decided to integrate it as a util instead of publishing it as a separate package since we seem to be the only project using it, and adopting it into a new project requires barneycarroll/mattr, which does not seem to be used anywhere.
The code added here was taken from https://github.com/askvortsov1/m.attrs.bidi, a fork (without changes) of the tobscure repo. Support for alternative module systems and ways of registering bidi were removed, and the file was formatted in compliance with our prettier config.
* Run extenders exported by extensions
* Add some basic extenders
* Patch Mithril as the very first thing so extension code can run safely
* Load the payload into the app before booting extensions
* Setup default routes before booting extensions
* Replace gulp with webpack and npm scripts for JS compilation
* Set up Travis CI to commit compiled JS
* Restructure `js` directory; only one instance of npm, forum/admin are "submodules"
* Refactor JS initializers into Application subclasses
* Maintain partial compatibility API (importing from absolute paths) for extensions
* Remove minification responsibility from PHP asset compiler
* Restructure `less` directory
