Calling this pivotal macro "def-package!" has frequently been a source
of confusion. It is a thin wrapper around use-package, and it should be
obvious that it is so. For this reason, and to match the naming
convention used with other convenience macros/wrappers, it is now
use-package!.
Also changes def-package-hook! -> use-package-hook!
The old macros are now marked obsolete and will be removed when straight
integration is merged.
- Adds the auto-minor-mode package to replace our in-house
implementation.
- Merges associate! into the def-project-mode! macro because associate!
on its own is less useful than auto-minor-mode-alist,
auto-minor-mode-magic-alist or hooks.
- Changes the semantics of :modes and :add-hooks properties of
def-project-mode!. Its arguments are evaluated as is; lists will need
to be quoted.
squash! core-lib: remove associate! macro
TAB now either indents, expands the snippet at point, or expands the
emmet expression at point.
Also it now falls back to emmet-expand-line if yasnippet won't load.
load!'s first argument is no longer a symbol (that will cause
void-variable errors now) to save on unnecessary interning and simplify
compile-time logic. It accepts any valid form that evaluates to a string
now.
If you use load!, you need to change its argument to a string!
e.g. (load! +my-module) => (load! "+my-module")
+ 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.
