+ New `input` and `buffer` support for :defer in def-package! can now
defer packages until the first command invoked after startup or first
interactive buffer switch, respectively
+ Exploit these new :defer techniques to lazy-load many core packages,
netting Doom a 20-30% decrease in startup time
+ Various userland macros (like package!, def-package-hook!, packages!,
and disable-packages!) will now throw an error if used incorrectly
(i.e. outside of their intended files; e.g. package! should be used in
packages.el files)
+ Removed support for multiple/nested doom! calls. There should only be
THE ONE in ~/.doom.d/init.el (or ~/.config/doom/init.el)
+ Fix an issue where load-path and auto-mode-list modifications would
not persist because doom-packages-file was cached too late.
+ Added package-activated-list to cached variables in
doom-packages-file, thus we no longer need custom-file.
+ Load Doom core files from doom-initialize. Now doom-initialize can be
called from state-dependent non-interactive functions, instead of
reloading core/core.el, which was clumsy
+ Removed the doom-post-init-hook hook. There was no reason for it to
exist when doom-init-hook can simply be appended to
+ doom-project can now be a symbol or list of project modes.
+ doom-project-hook hooks are promised to receive the mode symbol and
state, but until now only received the former.
+ Add docstrings to doom-project-{find-file,browse}.
+ doom|autoload-project-mode is now on find-file-hook instead of
after-change-major-mode (which fires it way too many times).
+ Renamed :init to :on-load (run once, the first time the project mode
is activated).
+ New properties :on-enter FORM and :on-exit FORM (run each time the
mode is enabled or disabled, respectively).
+ New property :hooks HOOKS (automatically add HOOKS to mode-hook).
+ Add doom-init-hook and doom-post-init-hook to simplify Emacs init
hooks into less ambiguous ones.
+ Attach former after-init-hook and emacs-startup-hook hooks to new doom
init hooks.
+ Vastly improves daemon and tty support: preventing incorrect colors
from bleeding across face class barriers, and into GUI Emacs and vice
versa, when spawned with emacsclient.
+ Fix persp-mode breaking Emacs daemon, and ensuring that initialization
is done properly in terminal Emacs (and emacsclient frames).
+ 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.
