featurep! will be renamed modulep! in the future, so it's been
deprecated. They have identical interfaces, and can be replaced without
issue.
featurep! was never quite the right name for this macro. It implied that
it had some connection to featurep, which it doesn't (only that it was
similar in purpose; still, Doom modules are not features). To undo such
implications and be consistent with its namespace (and since we're
heading into a storm of breaking changes with the v3 release anyway),
now was the best opportunity to begin the transition.
:feature was a "catch-all" category. Many of its modules fit better in
other categories, so they've been moved:
- feature/debugger -> tools/debugger
- feature/evil -> editor/evil
- feature/eval -> tools/eval
- feature/lookup -> tools/lookup
- feature/snippets -> editor/snippets
- feature/file-templates -> editor/file-templates
- feature/workspaces -> ui/workspaces
More potential changes in the future:
- A new :term category for terminal emulation modules (eshell, term and
vterm).
- A new :os category for modules dedicated to os-specific functionality.
The :tools macos module would fit here, but so would modules for nixos
and arch.
- A new :services category for web-service integration, like wakatime,
twitter, elfeed, gist and pastebin services.
- Removes +gist/kill-cache (gist-list and gist-list-user with a
universal argument already does this).
- Removes +gist/open-current. No longer necessary when gists aren't
opened in popups.
- Makes keybinds more consistent with other "porcelains", like elfeed's
or magit.
+ 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.
