+ 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.

;;; core-packages.el --- package management system -*- lexical-binding: t; -*-
|
|
|
|
;; Emacs package management is opinionated. Unfortunately, so am I. I've bound
|
|
;; together `use-package', `quelpa' and package.el to create my own,
|
|
;; rolling-release, lazily-loaded package management system for Emacs.
|
|
;;
|
|
;; The three key commands are `doom/packages-install', `doom/packages-update'
|
|
;; and `doom/packages-autoremove', which can be called via `make' on the command
|
|
;; line (make {install,update,autoremove}). These read packages.el files in each
|
|
;; activated module in `doom-modules-dir' (and one in `doom-core-dir') which
|
|
;; tell DOOM what plugins to install and where from.
|
|
;;
|
|
;; Why all the trouble? Because:
|
|
;; 1. Scriptability: I live in the command line. I want a programmable
|
|
;; alternative to `list-packages' for updating and installing packages.
|
|
;; 2. Flexibility: I want packages from sources other than ELPA. Primarily
|
|
;; github, because certain plugins are out-of-date through official channels,
|
|
;; have changed hands, or simply aren't in any ELPA repo.
|
|
;; 3. Stability: I used Cask before this. It would error out with cyrptic errors
|
|
;; depending on the version of Emacs I used and the alignment of the planets.
|
|
;; No more.
|
|
;; 4. Performance: A minor point, but this system is lazy-loaded (more so if you
|
|
;; byte-compile). Not having to initialize package.el (or check that your
|
|
;; packages are installed) every time you start up Emacs affords us precious
|
|
;; seconds.
|
|
;; 5. Simplicity: No Cask, no external dependencies (unless you count make),
|
|
;; just Emacs. Arguably, my config is still over-complicated, but shhh, it's
|
|
;; fine. Everything is fine.
|
|
;;
|
|
;; You should be able to use package.el commands without any conflicts, but to
|
|
;; be absolutely certain use the doom alternatives:
|
|
;;
|
|
;; + `package-install': `doom/install-package'
|
|
;; + `package-reinstall': `doom/reinstall-package'
|
|
;; + `package-delete': `doom/delete-package'
|
|
;; + `package-update': `doom/update-package'
|
|
;; + `package-autoremove': `doom/packages-autoremove'
|
|
;; + `package-refresh-contents': `doom/refresh-packages'
