Apparently, we didn't have one of these, and thus had a moderate
number of generally very old violations in the codebase. Fix this and
clear the ones that exist..
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
We want to avoid doing too much setup for the info overlay widget
during initialization, since we don't really need it, and side
effects like focusing a modal can cause hard-to-detect
glitches for other features.
We now have components.toggle simply return an object, without
putting the object into a lookup table. The consumers of the
objects have all been changed to just store the object in their
own module scope.
The diff is a bit hard to read here, but it's mostly de-denting
code and removing these things:
- we don't have opts.name
- we don't have __toggle.lookup
- we don't have keys
- we don't create a sibling object to the prototype object
We now make sure our toggler exists before invoking its `goto`
method. Usually a toggler exists pretty early during app
startup, but _setup_info_overlay is wrapped in i18n.ensure_i18n,
which asynchronously fetches translation data.
This commit also simplifies how we find the toggler, by just
storing it in the module where it gets created and consumed.
Fixes#9085.
For info overlays (keyboard/markdown/search help) we now let
the modal portions of the widget have focus, so that you can
page around. And then tab switching still works with the arrow
keys.
There are several ways we open help for keyboard shortcuts,
markdown help, and search operators.
- from the gear menu
- from the compose box
- from the search box
- hitting ? for keyboard help
- arrowing/clicking through the tabs
This just moves the relevant code into a module and changes a
bunch of one-line calls in various places.
