Fixes an issue where dtrt-indent and/or nav-flash would hang Emacs when
opening large files, and disables all mode hooks for large
files (without using fundamental-mode so you can at least get syntax
highlighting).
This update may potentially break your usage of add-hook! if you pass
the :local or :append properties to it. This is how they used to work:
(add-hook! :append 'some-mode-hook #'do-something)
Thsoe properties must now follow the hooks, e.g.
(add-hook! 'some-mode-hook :append #'do-something)
Other changes:
- Various add-hook calls have been renamed to add-hook! because I
incorrectly assumed `defun` always returned its definition's symbol,
when in fact, its return value is "undefined" (so sayeth the
documentation). This should fix#1597.
- This update adds the ability to add multiple functions to hooks
without a list:
(add-hook! 'some-mode-hook
#'do-something
#'do-something-else)
- The indentation logic has been changed so that consecutive function
symbols at indented at the same level as the first argument, but forms
are indent like a defun.
(add-hook! 'some-mode-hook
#'do-something
#'do-something-else)
(add-hook! 'some-mode-hook
(message "Hello"))
Calling this pivotal macro "def-package!" has frequently been a source
of confusion. It is a thin wrapper around use-package, and it should be
obvious that it is so. For this reason, and to match the naming
convention used with other convenience macros/wrappers, it is now
use-package!.
Also changes def-package-hook! -> use-package-hook!
The old macros are now marked obsolete and will be removed when straight
integration is merged.
This is second of three big naming convention changes. In this commit,
we change the naming conventions for hook functions and variable
functions:
1. Replace the bar | to indicate a hook function with a -h suffix, e.g.
doom|init-ui -> doom-init-ui-h
doom|run-local-var-hooks -> doom-run-local-var-hooks-h
2. And add a -fn suffix for functions meant to be set on variables,
e.g.
(setq magit-display-buffer-function #'+magit-display-buffer-fn)
See ccf327f8 for the reasoning behind these changes.
This is first of three big naming convention updates that have been a
long time coming. With 2.1 on the horizon, all the breaking updates will
batched together in preparation for the long haul.
In this commit, we do away with the asterix to communicate that a
function is an advice function, and we replace it with the '-a' suffix.
e.g.
doom*shut-up -> doom-shut-up-a
doom*recenter -> doom-recenter-a
+evil*static-reindent -> +evil--static-reindent-a
The rationale behind this change is:
1. Elisp's own formatting/indenting tools would occasionally struggle
with | and * (particularly pp and cl-prettyprint). They have no
problem with / and :, fortunately.
2. External syntax highlighters (like pygmentize, discord markdown or
github markdown) struggle with it, sometimes refusing to highlight
code beyond these symbols.
3. * and | are less expressive than - and -- in communicating the
intended visibility, versatility and stability of a function.
4. It complicated the regexps we must use to search for them.
5. They were arbitrary and over-complicated to begin with, decided
on haphazardly way back when Doom was simply "my private config".
Anyhow, like how predicate functions have the -p suffix, we'll adopt the
-a suffix for advice functions, -h for hook functions and -fn for
variable functions.
Other noteable changes:
- Replaces advice-{add,remove}! macro with new def-advice!
macro. The old pair weren't as useful. The new def-advice! saves on a
lot of space.
- Removed "stage" assertions to make sure you were using the right
macros in the right place. Turned out to not be necessary, we'll
employ better checks later.
:feature was a "catch-all" category. Many of its modules fit better in
other categories, so they've been moved:
- feature/debugger -> tools/debugger
- feature/evil -> editor/evil
- feature/eval -> tools/eval
- feature/lookup -> tools/lookup
- feature/snippets -> editor/snippets
- feature/file-templates -> editor/file-templates
- feature/workspaces -> ui/workspaces
More potential changes in the future:
- A new :term category for terminal emulation modules (eshell, term and
vterm).
- A new :os category for modules dedicated to os-specific functionality.
The :tools macos module would fit here, but so would modules for nixos
and arch.
- A new :services category for web-service integration, like wakatime,
twitter, elfeed, gist and pastebin services.
+ Add doom-switch-frame-hook
+ Replace doom-{enter,exit}-{buffer,window}-hook with
doom-switch-{buffer,window}-hook
+ New switch-buffer hooks run on buffer-list-update-hook rather than
in select-window advice.
+ Blank our buffer-list-update-hook in some places to reduce how many
times it gets triggered.
+ Add +nav-flash-exclude-commands to control where
+nav-flash-blink-cursor-maybe should not trigger nav-flash.
+ Rename API to conform to Doom naming conventions
+ +nav-flash-blink-cursor
+ +nav-flash-blink-cursor-maybe
+ +nav-flash|delayed-blink-cursor
+ +nav-flash|blink-cursor
+ +nav-flash|blink-cursor-maybe
+ +nav-flash*blink-cursor
+ doom-before-switch-buffer-hook => doom-exit-buffer-hook
+ doom-before-switch-window-hook => doom-exit-window-hook
+ doom-after-switch-buffer-hook => doom-enter-buffer-hook
+ doom-after-switch-window-hook => doom-enter-window-hook
Shorter, easier-to-type names that better describe their intended
purpose.
The old names are still usable, but deprecated.
Now that we are loading package autoloads files (as part of the
generated doom-package-autoload-file when running make autoloads), many
:commands properties are redundant. In fact, many def-package! blocks
are redundant.
In some cases, we can do without a config.el file entirely, and can move
into the autoloads file or rely entirely on package autoloads.
Also, many settings have been moved in their module's autoloads files,
which makes them available ASAP; their use no longer depends on module
load order.
This gained me a modest ~10% boost in startup speed.
+ enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster
startup; ~5-20% general boost
+ reduce consing, function calls & garbage collection by preferring
cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and
various cl-lib filter/map/reduce functions) -- where possible
+ prefer functions with dedicated opcodes, like assq (see byte-defop's
in bytecomp.el for more)
+ prefer pcase & cond (faster) over cl-case
+ general refactor for code readability
+ ensure naming & style conventions are adhered to
+ appease byte-compiler by marking unused variables with underscore
+ defer minor mode activation to after-init, emacs-startup or
window-setup hooks; a customization opportunity for users + ensures
custom functionality won't interfere with startup.
