It used to be that after! suppressed macro expansion, but at some point
around 28.1, the elisp interpreter started recognizing the
compiler-macro hint in eval-after-load's definition; implicitly wrapping
quoted forms in a function. Therefore, we can no longer rely on
eval-after-load to hide macros from the byte-compiler. Instead, modules
will need to take care to wrap macro calls in `eval` or similar, on a
case-by-case basis.
This fixes a couple bugs with this macro:
- Nested %-refs (in nested fn!'s) were interpolated as arguments of the
outer-most fn!. E.g. (fn! (fn! %2)) would expand to:
Before this fix:
(lambda (_%1 %2)
(lambda (_%1 %2)
%2))
After this fix:
(lambda ()
(lambda (_%1 %2)
%2))
- Unused arguments were not only listed in the wrong order, they were
off-by-one. E.g.
(fn! %3 %5) expands to (lambda (_%4 _%3 %3 _%1 %5) %3 %5)
This never caused any actual issues, but it was unexpected.
I've also moved the lookup table to `fn!`, and removed unnecessary
entries from it.
startup-redirect-eln-cache adds the new directory and removes
$EMACSDIR/eln-cache from native-comp-eln-load-path, but it's not
available in 28.1, so we'll have to wait until Doom drops 28.1 support
to use it.
doom-etc-dir will be renamed to doom-data-dir, to better reflect its
purpose, and align it with XDG_DATA_HOME (where it will be moved to in
v3, where Doom will begin to obey XDG directory conventions more
closely).
- Deprecates the doom-private-dir variable in favor of doom-user-dir.
- Renames the pseudo category for the user's module: :private -> :user.
- Renames the doom-private-error error type to doom-user-error.
Emacs uses the term "user" to refer to the "things" in user space (e.g.
user-init-file, user-emacs-directory, user-mail-address, xdg-user-dirs,
package-user-dir, etc), and I'd like to be consistent with that. It also
has the nice side-effect of being slightly shorter. I also hope
'doom-user-error' will be less obtuse to beginners than
'doom-private-error'.
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.
To reduce redundancy, remove the maintenance hassle that version
constants would impose later on, and rely on built-in
facilities (featurep) more over global variables or doomisms, these
global constants have been deprecated in favor of Emacs "features":
- EMACS28+ -- replace with (> emacs-major-version 27)
- EMACS29+ -- replace with (> emacs-major-version 28)
- NATIVECOMP -- replace with (featurep 'native-compile)
- MODULES -- replace with (featurep 'dynamic-modules)
(These constants will be formally removed when v3 is released. The IS-*
constants are likely next, but I haven't decided on their substitutes
yet)
I also decided to follow native-compile's example and provide features
for Emacs' system features (since system-configuration-features' docs
outs itself as a poor method to detect features):
- dynamic-modules
- jansson
- native-compile -- this one already exists, but will instead be removed
if it's non-functional; i.e. (native-comp-available-p) returns nil.
These are now detectable using featurep, which is fast and built-in.
Some of our comments/docs can come off as disparaging or snide. They're
glimpses of unfiltered frustration or snarky rubber ducking gone too
far, something I can totally sympathize with, as a scatterbrained
tinkerer, unwittingly made responsible for a lot of work that isn't mine
because of Doom's position as a middleman. But now that Doom has a
veritable userbase, I'd like to hold it to a higher standard.
Light-hearted banter and aired grievances in our source code,
documentation, or community are fine if focused on the problem or the
personal/shared experiences of the community (things that offer value or
amusement to others), but it is never acceptable to attack people or
their efforts. Especially not the very people on whose shoulders Doom
stands.
I sincerely apologize if these have offended you.

A regression introduced in 1d8c61698b. Doom disables its
file-name-handler-alist optimization if in a daemon session or if debug
mode is active.
Fix: #6657
Amend: 1d8c61698b
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.
If you've moved $EMACSDIR, comp-el-to-eln-filename will throw errors
about missing directories/files, rendering 'doom sync' ineffective and
forcing the user to delete $EMACSDIR and reinstall Doom.
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.
If vterm-buffer-name-string is set to non-nil, then vterm will rename
the buffer after it is initialized. Since +vterm/toggle looks up buffers
by name, it will lose track of them, causing it to create a new one on
each invocation. With this, it will no longer lose track of them.
Fix: #6651
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
Unsetting file-name-handler-alist around a `load` call prevents any
change to this variable from surviving that file's evaluation (e.g. by
packages loaded therein). Since the user's config files are loaded with
this macro, this affects users' configs, which is unacceptable.
Since this optimization is already done in early-init.el, we can get
away with being more selective here.
See 6f1c0f7cc7 for part 1.
Turns out startup.elc likely exists on most Emacs installations (and,
since it's so integral to Emacs, it likely gets special treatment), so
it was a poor heuristic for this fix. Instead, a more variable target
would be calc-loaddefs.el.
On some systems, only calc-loaddefs.el.gz exists (in which case, we
should turn off the optimization). On others, calc-loaddefs.el
exists (so I'll assume it's safe to leave them on). I won't check for
calc-loaddefs.elc because it doesn't matter; calc.el explicitly
calls (load "calc-loaddefs.el") so it is never loaded.
Of course, you can sidestep the entire issue by building Emacs with
--without-compress-install, but it's not practical for users to
know/want to do that.
Amend: 6f1c0f7cc7
Some installs of Emacs do not come with byte-compiled versions of its
bundled elisp files, so when loading them, Emacs falls back to loading
its *.el.gz files. This would be fine if it were not for a startup
optimization Doom employs, where it sets file-name-handler-alist to
nil (and by doing so, robs Emacs of the ability to read compressed
elisp). This causes "symbol's value as variable is void: \213" errors at
startup.
With this commit, Doom now disables this optimization early if it
suspects this applies to your install. But time will tell if it's early
enough.

Based on the new variable `+tree-sitter-hl-enabled-modes`
This allows for people to use tree sitters tools without having
to use it for highlighting.
Useful because some modes (such as web-mode and its derivatives) do a
better job than the tree sitter alternative in this respect.
If tangling failed, it would do so silently, continuing on with the
'doom sync'. This causes a visible error instead, aborting the 'doom
sync'. Unfortunately, org-babel-tangle doesn't appear to produce any
errors, so this our error message can't be improved at this stage.
Fix: #6642
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.
