The defaults were designed for much, much older systems. We can safely
increase this to stave off premature abortion of intentional deeply
nested loops or excessive allocations.
+ Add doom-gc-cons-upper-limit variable
+ Don't use most-positive-fixnum, in case Emacs somehow wants to
allocate that much!
+ Don't use startup optimizations in noninteractive sessions
+ Restore gc-cons-threshold on idle timer, instead of hook (to defer the
possible GC pause and so deferred packages can take advantage of these
optimizations).
This was done to help the modeline build its file path in indirect
buffers, but this has been fixed by using buffer-base-buffer.
Both ui/modeline and ui/doom-modeline have been refactored to
accommodate this.
This change facilitates the users that prefer their custom-file
somewhere other than doom-local-dir (e.g. in ~/.doom.d/custom.el).
This change prevents loading both files during startup. Just change
`custom-file` and Doom will load it after your config.el is loaded (but
before doom-post-init-hook runs).
Possibly fixes recursive load errors, to do with
kill-buffer-query-functions and buffer-predicate autoloads loading in a
weird way on Emacs 25 (and especially on MacOS, for some reason).
Also ensures that the custom hooks aren't fired until as late as
possible, which prevents a few packages from prematurely loading at
startup. Faster startup! Yay!
doom! no longer loads modules, it only sets
doom-modules (incrementally).
Instead, modules are loaded by doom-initialize-modules (which makes more
sense).
This restores the correct value of noninteractive while core libs are
loading, so packages like recentf can avoid initializing when running
emacs non interactively (thus polluting output or possibly causing
errors).
+ Removes redundant/unhelpful comments
+ Renames functions, hooks and variables to be self-documenting
+ Use add-to-list to ensure idempotency (and is more performant)
Another refactor, again to improve the locality of doom errors and make
the data that accompanies them more useful in determining the origin and
source of issues. Also, bin/doom is now a little more informative about
how to debug errors.
Caused because of symbol-file advice assuming SYMBOL would always be a
symbol.
This would prevent backtraces from happening, making debugging
impossibly obtuse.
This may indirectly fix#701
The error handlers were a little too effective. They obscured a large
chunk of the stacktrace after errors, even in debug mode. This fixes
that and ensures backtraces in debug mode are more helpful.
This fix prevented the byte-compiler from trying to load packages that
were disabled or failed their :when/:unless/:if predicates. This commit
moves it into doom-byte-compile, so the :no-require predicate doesn't
have to run on every package in an interactive session, eating MY
PRECIOUS cpu cycles.
I do love my cpu cycles, yessiree.
This will hopefully reveal more information as to the cause and origin
of errors at startup. It should also make doom-debug-mode more likely to
produce a backtrace in non-interactive sessions.
This naming convention was meant to be for batch commands, but it grew
to include "commands that were helpful with managing Doom", but many of
these commands shouldn't be interactive in the first place!
...if it exists. Otherwise fall back on original functionality. This
allows certain symbols to overwrite where Emacs thinks they were
defined.
Warning: only use this for autodefs! It may have unintended side-effects
for other symbols.
+ Move doom-initialize et co into core.el
+ Lazy load core-packages
+ load! has been moved into core-lib
+ Added FILE! and DIR! macros
+ Fix package! not returning correct value when package is disabled
+ Remove :disabled support for def-package-hook! officially
Removes doom-module-table; which was inflexible (though more stable). It
prevented you from putting your doom! block in anywhere but
~/.doom.d/init.el.
It is replaced (somewhat) by (doom-modules).
The autoloads file has been split into doom-autoload-file and
doom-package-autoload-file. The former is for Doom's modules and
standard library; the latter is for compiling all package autoloads like
load-path and auto-mode-alist (among other things).
This reduced my startup speed from ~1s to ~0.5s
This offloads some of the work Doom has to do creating
`doom-packages-file` onto `make autoloads`. This closely mimics the
package-quickstart-refresh functionality in Emacs 27+, but is more
specialized.
This means package autoloads are now loaded on every startup.
Many :mode, :interpreter, and :commands declarations in def-package!
blocks are made redundant by this and will be cleaned up soon.
:defer now supports a hook, a cons cell with (SYMBOL . INTEGER) where
SYMBOL is a hook and INTEGER is a number of idle seconds before the
package is autoloaded, or just the integer (as per the default behavior
of :defer).
Also fixes an issue where switch-buffer-deffered packages (like
smartparens) wouldn't load.
+ 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
The config/private module has been removed. ~/.doom.d (or
~/.config/doom; whichever is detected first) is now a first class
citizen of Doom and should just work(tm).
Your init.el only needs to contain:
(require 'core (concat user-emacs-directory "core/core"))
And you may place your doom! block in ~/.doom.d/init.el (or
~/.config/doom/init.el).
Formerly, you were required to have a doom! call (even a blank one) in
~/.doom.d/init.el if you wanted to have private sub-modules in
~/.doom.d/modules/.
No more. It is no longer doom!'s responsibility to affect
`doom-modules-dirs`. This is now done by :config private, while the
Doom modules directory is now the initial entry in doom-modules-dirs.
+ Fix#446, where the .local/packages.el cache was generated with
a faulty load-path.
+ Entries in the doom-modules hash table are now plists, containing
:flags and :path, at least.
+ Add doom-initialize-modules for loading module config.el files.
+ Add doom-module-get for accessing this plist, e.g.
(doom-module-get :some module) ; returns plist
(doom-module-get :some module :flags) ; return specific property
+ Replace doom-module-enable with doom-module-set, e.g.
(doom-module-set :some module :flags '(+a +b +c))
+ Remove doom-module-flags (use doom-module-get instead)
+ Rename doom-module-enabled-p with doom-module-p
+ Replace doom-module-path with doom-module-find-path and
doom-module-expand-file. The former will search for an existing module
or file in doom-modules-dirs. The latter will expand the path from
whatever path is stored in doom-modules.
+ Replace doom-module-paths with doom-module-load-path
+ Changed doom! to allow for nested doom! calls by delaying the loading
of module config.el files until as late as possible.
+ Refactor doom-initialize-packages to only ihitialize package state
(i.e. doom-packages, package-alist, and quelpa-cache), rather than its
previous behavior of loading all Doom files (and sometimes all module
files). This is faster and more predictable.
Doom saves a lot of startup time by avoiding package-initialize, because
it loads every packages' autoloads file, which is expensive.
Unfortunately, these autoloads files are necessary for some plugins with
abnormal file structures (such as ESS). Previously, I was content with
loading them myself, but these occurrences have become more frequent, so
it would be safest if I relied on package-initialize more.
So doom-initialize will now do so. However, it will cache the load-path
(and Info-directory-list, fixing the lost info buffers) on first run.
This makes byte-compiling Doom almost useless, but it makes startup just
as fast as Doom would be if you had.
This needs more testing.
Any module can now use a doom! call to declare a module tree root.
This means that if you have a doom! block in
~/.emacs.d/modules/lang/org/init.el, then you can have submodules in
~/.emacs.d/modules/lang/org/modules/MODULE/SUBMODULE if you wanted to
for some reason.
This is only really truly useful for private modules. A doom! block in
~/.doom.d/init.el will recognize and enable modules in
~/.doom.d/modules/.
~/.doom.d/modules is now a full module tree, like ~/.emacs.d/modules.
Symlinks are no longer involved.
Private modules can now shadow Doom modules. e.g.
~/.doom.d/modules/lang/org will take precendence over
~/.emacs.d/modules/lang/org.
Also, made doom--*-load-path variables public (e.g. doom--site-load-path
=> doom-site-load-path), and rearranged the load-path for a 10-15%
startup boost.
This is a breaking change! Update your :popup settings. Old ones will
throw errors!
Doom's new popup management system casts off its shackles (hur hur) and
replaces them with the monster that is `display-buffer-alist`, and
window parameters.
However, this is highly experimental! Expect edge cases. Particularly
with org-mode and magit (or anything that does its own window
management).
Relevant to #261, #263, #325
Local cache and data files were stored in a parent folder named after
your host, because I'd symlink the same config across computers via
dropbox. This would cause byte-compile issues in packages, so I stopped
doing this.
Now that each computer gets its own clone, host-namespaced local
directories are unnecessary. There's no other benefit to having them.
This refactor is about improving how Emacs deals with errors.
A large net is now cast at startup to catch possible errors, produce
more helpful error messages, and localize the damage. Significantly
reducing the risk of later modules not loading (and leaving you
stranded in a half-broken Emacs session).
The DOOM core files are an exception. If something messes up in there,
it *should* choke.
+ use-package will now report missing packages or slow-loading/broken
def-package! configurations.
+ Persp-mode no longer (inadvertantly) hides buffers that pop up at
startup, like the *Warnings*, *Backtrace* or debugger buffers.
+ `make autoloads` (or doom/reload-autoloads) now produces a slightly
more informative error message if an error occurs while building the
autoloads file.
+ Error handling for package management is *slightly* better now; error
messages now include the type of error; this needs work.
+ 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.
