Company backends are now built from an alist (+company-backend-alist),
which can be manipulated through set-company-backend!. Backends can now
be set to all children of a parent mode (text-mode, prog-mode, etc),
like so:
(set-company-backend! :derived 'text-mode 'company-dabbrev)
or only for an exact major-mode:
(set-company-backend! 'markdown-mode 'company-dabbrev-code)
Backends cascade. So combining the two examples above will cause
company-backends in a markdown-buffer (which is derived from text-mode)
to be (company-dabbrev-code company-dabbrev).
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.
: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.
set! used to aggressively evaluate its arguments (at expansion-time),
even if placed inside an after! block. This causes unavoidable errors if
those arguments use functions/variables that don't exist yet.
Fixes#112
+ 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.
