What is Doom Emacs

It is a story as old as time. A stubborn, shell-dwelling, and melodramatic as vimmer -- envious of the features of modern text editors -- spirals into despair before succumbing to the dark side. This is his config.

Doom is a configuration framework for GNU Emacs tailored for Emacs bankruptcy veterans who want less framework in their frameworks and the performance of a hand rolled config (or better). It can be a foundation for your own config or a resource for Emacs enthusiasts to learn more about our favorite OS.

Doom's mantras

• Gotta go fast. Startup and run-time performance are priorities. Doom goes beyond lazy loading packages by modifying them to be snappier and load lazier!
• Close to metal. There's less between you and vanilla Emacs by design. There's less to grok, on top of Emacs.
• Readability counts. Internals ought to be written as if reading them were part of the user experience, and it is! Modules should be syntactically sweet. Backend logic should be functional (as much as elisp permits), abstraction light and (hopefully) documented.
• Opinionated, but not stubborn. Doom is a bundle of reasonable defaults and curated opinions, but all of it should be optional. Use as little or as much of it as you like.
• Your system, your rules. There are more ways to set up your development environment than there are dislikes on Youtube Rewind '18, so Doom leaves it to you. Doom will not automatically install system dependencies (and will coerce its plugins not to do so either). Use doom doctor to figure out what's missing.

Features

• Minimalistic good looks inspired by modern editors.
• A modular architecture for a more organized Emacs configuration.
• A custom elisp library to help simplify your config.
• (Optional) Vim-emulation powered by evil-mode, including ports of popular vim plugins and functionality.
• A declarative package management system (powered by straight.el) with a command line interface. Install packages from anywhere, not just (M)ELPA.
• A curated set of sane defaults for all packages, all (major) OSes, and Emacs itself.
• Support for many programming languages. Too many to list. Includes syntax highlighting, linters/checker integration, inline code evaluation, code completion (where possible), REPLs, documentation lookups, snippets, and more!
• Support for many tools, like docker, pass, ansible, terraform, and more.
• A Spacemacs-esque keybinding scheme, centered around leader and localleader prefix keys (SPC and SPCm, by default).
• A rule-based popup management system that dictates how temporary or disposable buffers are displayed (and disposed of).
• Automatic indentation detection and editorconfig integration. Let someone else argue about tabs vs _*spaces*_.
• Project-management tools and framework-specific minor modes with their own snippets libraries.
• Project search (and replace) utilities, powered by ripgrep.
• Isolated and persistent workspaces (also substitutes for vim tabs).
• An envvar file generator that captures a snapshot of your shell environment for Doom to load at startup. No more struggling to get Emacs to inherit your PATH, among other things.

Troubleshooting

Encountered strange behavior or an error? Here are some things to try before you shoot off that bug report:

• Run bin/doom sync. This ensures Doom is properly set up and its autoloads files are up-to-date.
• If you have byte-compiled your config (with bin/doom compile), see if bin/doom clean makes the issue go away. Never debug issues with a byte-compiled config, it will make your job harder.
• Run bin/doom doctor to detect common issues in your development environment.
• Search Doom's issue tracker for mention of any error messages you've received.
• Visit our FAQ to see if your issue is listed.

If all else fails, file that bug report! Please include the behavior you've observed, the behavior you expected, and any error messages or warnings logged to the *Messages* buffer (can be opened with SPC h e or M-x view-echo-area-messages).

It's a great help if you included a backtrace with errors, i.e. M-x toggle-debug-on-error then recreating the error(s).
