This makes package.el commands safe to use in Doom, and prevents errors
caused by unitialized state, by running package-initialize before
you use a package.el command.
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.
Autoload paths used to be relative to arbitrary roots (usually
doom-modules-dir). This commit changes doom//reload-autoloads to iterate
over autoloads in doom-autoloads-file and replace their file paths with
an absolute one.
Theoretically this should make Emacs feel marginally faster, but we
*probably* get more of a benefit from a shorter load-path (because we no
longer need doom-modules-dirs, doom-core-dir or doom-psuedo-module-paths
in the load-path).
This is highly experimental however!
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.
Originally, I built the load-path with site-lisp paths first, then
packages. There was a modest ~10% startup boost doing this, because
there were considerably more site packages loaded at startup than
plugins.
However, this meant built-in packages would get precedence over plugins,
which is undesirable. In org's case, I simply modified the load-path
in lang/org/init.el. However, this issue has cropped up again in #340.
Evidently, that 10% boost may not be worth the risk it imposes, so I've
rearranged the load-path with packages first.
+ map-delete is shorter and faster than assq-delete-all
+ map-put is simpler than the delete-then-set workflow
+ map-merge is great for merging default and user settings
