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.
IMPORTANT: This is a breaking update for Mac users, as your shell
environment will no longer be inherited correctly (with the removal of
exec-path-from-shell). The quick fix is: 'bin/doom env refresh'. Also,
the set-env! autodef now does nothing (and is deprecated), be sure to
remove calls to it in your config.
Smaller changes:
+ This update also adds --no-* switches to doom quickstart
+ Includes general improvements to the documentation of several bin/doom
commands.
+ Moves doom/reload* commands to core/autoload/config.el
+ doom/reload-project has been removed (it didn't actually do anything)
The breaking change:
This update adds an "envvar file" to Doom Emacs. This file is generated
by `doom env refresh`, populated with variables scraped from your shell
environment (from both non-interactive and interactive sessions). This
file is then (inexpensively) loaded at startup, if it exists.
+ The file is manually generated with `doom env refresh`.
+ It can be regenerated automatically whenever `doom refresh` is run by
running `doom env enable` (`doom env clear` will reverse this and
delete the env file).
+ `doom quickstart` will ask if you want to auto-generate this envvar
file. You won't need it if you're confident Emacs will always be
started from the correct environment, however.
+ Your env file can be reloaded from a running Emacs session with `M-x
doom/reload-env`. Note: this won't work if the Emacs session you're
running it in doesn't have a correct SHELL set. i.e. don't use this to
create your first env file!
The idea isn't mine -- it's borrowed from Spacemacs -- and was
introduced to me in #1053 by @yurimx. I was impressed with it. Prior to
this, I was unhappy with exec-path-from-shell (no hate to the dev, I
understand its necessity), and 'doom patch-macos' wasn't ideal for mac
users (needed to be reapplied every time you update Emacs). What's more,
many users (even Linux users) had to install exec-path-from-shell
anyway.
This solution suffers from none of their shortcomings. More reliable
than patch-macos, more performant and complete than
exec-path-from-shell, and easily handled by bin/doom.
- doom-post-init-hook was renamed doom-init-modules-hook
- doom-init-hook was renamed doom-before-init-modules-hook
- doom-init-modules-hook now runs before the user's config.el is run
- Moved doom-init-ui-hook to run later (on window-setup-hook rather than
emacs-startup-hook).
Yield a modest improvement in startup times.
On MacOS, command used to be 'meta, which Emacs (and many packages) use
for many keybinds. I don't want to pollute the command key, so it is now
meta (as is the Emacs default).
The MacOS keybind fixes have been moved back to super.
Using meta is a little more flexible. Since there is no dedicated meta
key on our keyboards (anymore), it can be remapped to another modifier
by changing mac-command-modifier, x-meta-keysym, etc. without
sacrificing super or alt keybinds.
+ Now uses an overriding keymap for leader keys, so that it is always
available, even outside of normal/visual states. In insert/emacs
states, or in sessions where evil is absent, an alternative prefix is
used for leader/localleader keys. See these variables:
+ doom-leader-prefix
+ doom-leader-alt-prefix
+ doom-localleader-prefix
+ doom-localleader-alt-prefix
+ Keybinds now support alternative prefixes through the new :alt-prefix
property. This is useful for non-evil users and non-normal evil
states. By default, this is M-SPC (leader) and M-SPC m (localleader).
+ Removed +evil-commands flag from config/default (moved to
feature/evil/+commands.el).
+ config/default/+bindings.el has been split into
config/default/+{evil,emacs}-bindings.el, which one is loaded depends
on whether evil is present or not. The latter is blank, but will soon
be populated with a keybinding scheme for non-evil users (perhaps
inspired by #641).
+ The define-key! macro has been replaced; it is now an alias for
general-def.
+ Added unmap! as an alias for general-unbind.
+ The following modifier key conventions are now enforced for
consistency, across all OSes:
alt/option = meta
windows/command = super
It used to be
alt/option = alt
windows/command = meta
Many of the default keybinds have been updated to reflect this switch,
but it is likely to affect personal meta/super keybinds!
The map! macro has also been rewritten to use general-define-key. Here
is what has been changed:
+ map! no longer works with characters, e.g. (map! ?x #'do-something) is
no longer supported. Keys must be kbd-able strings like "C-c x" or
vectors like [?C-c ?x].
+ The :map and :map* properties are now the same thing. If specified
keymaps aren't defined when binding keys, it is automatically
deferred.
+ The way you bind local keybinds has changed:
;; Don't do this
(map! :l "a" #'func-a
:l "b" #'func-b)
;; Do this
(map! :map 'local "a" #'func-a
"b" #'func-b)
+ map! now supports the following new blocks:
+ (:if COND THEN-FORM ELSE-FORM...)
+ (:alt-prefix PREFIX KEYS...) -- this prefix will be used for
non-normal evil states. Equivalent to :non-normal-prefix in general.
+ The way you declare a which-key label for a prefix key has changed:
;; before
(map! :desc "label" :prefix "a" ...)
;; now
(map! :prefix ("a" . "label") ...)
+ It used to be that map! supported binding a key to a key sequence,
like so:
(map! "a" [?x]) ; pressing a is like pressing x
This functionality was removed *temporarily* while I figure out the
implementation.
Addresses: #448, #814, #860
Mentioned in: #940
On MacOS, the daemon is unlikely to run with the correct environment if
launched through launchctl or brew services, so it makes sense to use
exec-path-from-shell there too.
May address #736
:env lets you specify what environment variables exec-path-from-shell
should pull in from your shell environment at startup. As such, these
need to be defined at startup. :env is useless post-init.
May address #433
+ 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.
