;;; core/core-packages.el -*- lexical-binding: t; -*- ;; Emacs package management is opinionated, and so is Doom. Doom uses `straight' ;; to create a declarative, lazy-loaded and (nominally) reproducible package ;; management system. We use `straight' over `package' because the latter is ;; tempermental. ELPA sources suffer downtime occasionally and often fail to ;; build packages when GNU Tar is unavailable (e.g. MacOS users start with BSD ;; tar). Known gnutls errors plague the current stable release of Emacs (26.x) ;; which bork TLS handshakes with ELPA repos (mainly gnu.elpa.org). See ;; https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3434. ;; ;; What's worse, you can only get the latest version of packages through ELPA. ;; In an ecosystem that is constantly changing, this is more frustrating than ;; convenient. Straight (and Doom) can do rolling release, but it is opt-in. ;; ;; Interacting with this package management system is done through Doom's ;; bin/doom script. Find out more about it by running 'doom help' (I highly ;; recommend you add the script to your PATH). Here are some highlights: ;; ;; + `bin/doom install`: a wizard that guides you through setting up Doom and ;; your private config for the first time. ;; + `bin/doom sync`: your go-to command for making sure Doom is in optimal ;; condition. It ensures all unneeded packages are removed, all needed ones ;; are installed, and all metadata associated with them is generated. ;; + `bin/doom upgrade`: upgrades Doom Emacs and your packages to the latest ;; versions. There's also 'bin/doom update' for updating only your packages. ;; ;; How this works is: the system reads packages.el files located in each ;; activated module, your private directory (`doom-private-dir'), and one in ;; `doom-core-dir'. These contain `package!' declarations that tell DOOM what ;; plugins to install and where from. ;; ;; All that said, you can still use package.el's commands, but 'bin/doom sync' ;; will purge ELPA packages.
