`diff-hl-update-async` was enabled in f2696d7, causing a regression
where with-editor buffers wouldn't get cleaned up properly. This would
particularly affect Magit's COMMIT_EDITMSG buffers. To quote jds on
Discord:
It seems like after committing (with cc in the magit buffer), it
leaves COMMIT_EDITMSG around. The next time I try & commit, a single c
keypress immediately jumps to the old COMMIT_EDITMSG buffer, but it's
inactive - C-c C-c closes that buffer but makes no change to git.
I opt for advice instead of find-file or with-editor-mode hooks to
restore normal behavior should with-editor-mode be later disabled
without the death of its buffer (not relevant to magit, specifically,
but it might be to other consumers of with-editor, now or in the
future).

Amend: f2696d7302
These advice were unnecessary when not only does diff-hl expose
variables to change them, but one of the overridden definitions is
identical to the function it's replacing.
Also includes some other minor refactors.
The NS build of Emacs (on MacOS) seems to struggle rendering our old
fringe bitmaps for diff-hl, leading to noticably slow-downs when
scrolling in buffers with diff-hl enabled. By pre-computing the pixel
height and width of the bitmap, rather than relying on passing `repeat`
to define-fringe-bitmap's ALIGN argument, this seems to spare it a chunk
of wasted cycles.

BREAKING CHANGE: This removes git-gutter as an implementation for the
`:ui vc-gutter` module, leaving only the diff-hl implementation. There
are no longer any +git-gutter or +diff-hl flags for this module. Users
don't have to do anything to keep the vc gutter, unless they prefer
git-gutter for any reason (in which case they'll need to install and set
it up themselves).
This has been planned for some time, because of a roadmap goal for Doom
to lean into native/built-in functionality where it's equal or better
than the third party alternatives. diff-hl relies on the built-in vc.el
library instead of talking to git directly (thus expanding support to
whatever VCS's vc.el supports, and not git alone), which also means it
can take advantage of its caching and other user configuration for
vc.el. Overall, it is faster and lighter.
What I've also been waiting for was a stage-hunk command, similar to
git-gutter:stage-hunk, which arrived in dgutov/diff-hl@a0560551cd and
dgutov/diff-hl@133538973b, and have evolved since.

featurep! will be renamed modulep! in the future, so it's been
deprecated. They have identical interfaces, and can be replaced without
issue.
featurep! was never quite the right name for this macro. It implied that
it had some connection to featurep, which it doesn't (only that it was
similar in purpose; still, Doom modules are not features). To undo such
implications and be consistent with its namespace (and since we're
heading into a storm of breaking changes with the v3 release anyway),
now was the best opportunity to begin the transition.
A new convention I'm slowly rolling out to modules to help readers
quickly identify the purpose of a change. E.g.
UX - a change done to improve user experience
STYLE - for aesthetics
FIX - addresses a perceived or potential issue
PERF - intended to improve performance
Combined tags will be delimited with commas. E.g. "UX,PERF:"
There may be more later, and these will be further documented in the new
docs about to come up.
Originally, this intended to *stop* diff-hl from too aggressively
deleting the diff overlays while editing. This is either no longer the
case or the old advice was mistaken; the intended behavior is achieved
without it.
BREAKING CHANGE: users who are used to diff-hl displaying diffs in dired
will notice they have vanished. diff-hl's conig has been moved to :ui
vc-gutter +diff-hl (added in 27a448b). Enable it to get it back.
Ref: 27a448b04b
This adds an alternative backend to the :ui vc-gutter module, enabled
with the +diff-hl flag. In the future, I intend for diff-hl to replace
git-gutter, as it is slightly faster and depends on more native
functionality (vc.el), but it's still a little buggy. It will remain
opt-in until those issues are sorted out.
BREAKING CHANGE: This changes moves its default configuration of the
fringe behind a +pretty flag. This won't cause breakage, but will cause
a (possibly unwanted) visual change: git-gutter will use its default
indicators (e.g. + and - symbols) instead of the continuous bars from
before.
To get back the old look, enable `+pretty` on the `:ui vc-gutter`
module.
This was done to make the defaults toggleable, to standardize +pretty,
to document issues with this customization that have been brought up by
members of the Emacs community, and to better document it in comments
for posterity.
I've omitted docs/*.org from this merge, as there is still work left to
do there, but I am pushing the module docs early so folks can benefit
from the new docs sooner.
Fewer links means less confusion.
- Merge doom-issue and doom-commit links into doom-ref (for auto-linking
Issue/PR/commit references).
- Merge doom-module-source and doom-docs-source links into doom-source.
- Rename doom-report-issue to doom-report.
- Use '!' as the icon for module issues link.
- Remove doom-repo (replaced with "doom:*" in :lang org module).
- Add doomdir and emacsdir links to :lang org module.
this commit adds a default keybinding for the vc-gutter hydra (leader-g
.) if both vc-gutter and hydra are enabled. It ensures that the various
vc-*-log-view-modes open up in emacs state, and it adds hg, svn and bzr
to the list of vc backends handled by git-gutter
Caused by over-zealous doom-switch-window-hook.
For my own sanity (and if you're curious), I'll break it down here:
1. Doom has a `doom-switch-window-hook` hook. It triggers when window
focus is changed.
2. We use `buffer-list-update-hook` to trigger
`doom-switch-window-hook`. (That may sound weird, but this hook is
reliably executed when window focus is changed -- there are
safeguards to prevent this from triggering too often)
3. `buffer-list-update-hook` triggers whenever a buffer is created, but
`doom-switch-window-hook` only triggers if the created buffer is in
a new window.
4. The use of `with-temp-buffer` in `centaur-tabs-line-format` counts as
"buffer creation" in a "new window".
5. `+vc-gutter-update-h` is in `doom-switch-window-hook`. This refreshes
git-gutter, which initiates a redraw of Emacs.
6. When Emacs redraws, it recalculates its mode and header lines. which
triggers `doom-switch-window-hook` once, which triggers
`+vc-gutter-update-h`, which redraws the screen, then Emacs recalculates
the header line, running `centaur-tabs-line-format`...
Infinite loop ensues
Hopefully fixes:
- hlissner/doom-emacs#2436
- ema2159/centaur-tabs#18
- ema2159/centaur-tabs#88
