Backport bits of CLI rewrite
The rewrite for Doom's CLI is taking a while, so I've backported a few
important changes in order to ease the transition and fix a couple bugs
sooner.

Fixes #2802, #2737, #2386

The big highlights are:

- Fix #2802: We now update recipe repos *before* updating/installing any
  new packages. No more "Could not find package X in recipe repositories".

- Fix #2737: An edge case where straight couldn't reach a pinned
  commit (particularly with agda).

- Doom is now smarter about what option it recommends when straight
  prompts you to make a choice.

- Introduces a new init path for Doom. The old way:
  - Launch in "minimal" CLI mode in non-interactive sessions
  - Launch a "full" interactive mode otherwise.
  The new way
  - Launch in "minimal" CLI mode *only* for bin/doom
  - Launch is a simple mode for non-interactive sessions that still need
    access to your interactive config (like async org export/babel).
  - Launch a "full" interactive mode otherwise.

  This should fix compatibility issues with plugins that use the
  async.el library or spawn child Emacs processes to fake
  parallelization (like org's async export and babel functionality).

- Your private init.el is now loaded more reliably when running any
  bin/doom command. This gives you an opportunity to configure its
  settings.

- Added doom-first-{input,buffer,file}-hook hooks, which we use to queue
  deferred activation of a number of packages. Users can remove these
  modes from these hooks; altogether preventing them from loading,
  rather than waiting for them to load to then disable them,
  e.g. (after! smartparens (smartparens-global-mode -1)) -> (remove-hook
  'doom-first-buffer #'smartparens-global-mode)

  Hooks added to doom-first-*-hook variables will be removed once they
  run.

  This should also indirectly fix #2386, by preventing interactive modes
  from running in non-interactive session.

- Added `doom/bump-*` commands to make bumping modules and packages
  easier, and `doom/bumpify-*` commands for converting package!
  statements into user/repo@sha1hash format for bump commits.

- straight.el is now commit-pinned, like all other packages. We also
  more reliably install straight.el by cloning it ourselves, rather than
  relying on its bootstrap.el.

  This should prevent infinite "straight has diverged from master"
  prompts whenever we change branches (though, you might have to put up
  with it one more after this update -- see #2937 for workaround).

All the other minor changes:

- Moved core/autoload/cli.el to core/autoload/process.el
- The package manager will log attempts to check out pinned commits
- If package state is incomplete while rebuilding packages, emit a
  simpler error message instead of an obscure one!
- Added -u switch to 'doom sync' to make it run 'doom update' afterwards
- Added -p switch to 'doom sync' to make it run 'doom purge' afterwards
- Replace doom-modules function with doom-modules-list
- The `with-plist!` macro was removed, since `cl-destructuring-bind`
  already serves that purpose well enough.
- core/autoload/packages.el was moved into core-packages.el
- bin/doom will no longer die if DOOMDIR or DOOMLOCALDIR don't have a
  trailing slash
- Introduces doom-debug-variables; a list of variables to toggle on
  doom/toggle-debug-mode.
- The sandbox has been updated to reflect the above changes, also:
  1. Child instances will no longer inherit the process environment of
     the host instance,
  2. It will no longer produce an auto-save-list directory in ~/.emacs.d

completion/ivy

Description

This module provides Ivy integration for a variety of Emacs commands, as well as a unified interface for project search and replace, powered by ripgrep.

I prefer ivy over ido for its flexibility. I prefer ivy over helm because it's lighter, simpler and faster in many cases.

Module Flags

  • +fuzzy Enables fuzzy completion for Ivy searches.
  • +prescient Enables prescient filtering and sorting for Ivy searches.
  • +childframe Causes Ivy to display in a floating child frame, above Emacs.
  • +icons Enables file icons for switch-{buffer,project}/find-file counsel commands.

Plugins

Hacks

  • Functions with ivy/counsel equivalents have been globally remapped (like find-file => counsel-find-file). So a keybinding to find-file will invoke counsel-find-file instead.
  • counsel-[arp]g's 3-character limit was reduced to 1 (mainly for the ex command)

Prerequisites

This module depends on:

Install

MacOS

brew install ripgrep

Arch Linux

sudo pacman --needed --noconfirm -S ripgrep

openSUSE

sudo zypper install ripgrep

Features

Ivy and its ilk are large plugins. Covering everything about them is outside of this documentation's scope, so only Doom-specific Ivy features are listed here:

Jump-to navigation

Inspired by Sublime Text's jump-to-anywhere, CtrlP/Unite in Vim, and Textmate's Command-T, this module provides similar functionality by bringing projectile and ivy together.

https://assets.doomemacs.org/completion/ivy/projectile.png

Keybind Description
SPC p f, SPC SPC Jump to file in project
SPC f f, SPC . Jump to file from current directory
SPC s i Jump to symbol in file

Project search & replace

This module provides interactive text search and replace using ripgrep.

Keybind Description
SPC s p Search project
SPC s P Search another project
SPC s d Search this directory
SPC s D Search another directory

https://assets.doomemacs.org/completion/ivy/search.png

Prefixing these keys with the universal argument (SPC u for evil users; C-u otherwise) changes the behavior of these commands, instructing the underlying search engine to include ignored files.

This module also provides Ex Commands for evil users:

Ex command Description
:pg[rep][!] [QUERY] Search project (if !, include hidden files)
:pg[rep]d[!] [QUERY] Search from current directory (if !, don't search recursively)

The optional `!` is equivalent to the universal argument for the previous commands.


These keybindings are available while a search is active:

Keybind Description
C-c C-o Open a buffer with your search results
C-c C-e Open a writable buffer of your search results
C-SPC Preview the current candidate
C-RET Open the selected candidate in other-window

Changes to the resulting wgrep buffer (opened by C-c C-e) can be committed with C-c C-c and aborted with C-c C-k (alternatively ZZ and ZQ, for evil users).

In-buffer searching

The swiper package provides an interactive buffer search powered by ivy. It can be invoked with:

  • SPC s s (swiper-isearch)
  • SPC s S (swiper-isearch-thing-at-point)
  • SPC s b (swiper)
  • :sw[iper] [QUERY]

https://assets.doomemacs.org/completion/ivy/swiper.png

A wgrep buffer can be opened from swiper with C-c C-e.
