This section is for general questions about the Doom Emacs project and its
author.

** Is Emacs (or Doom) for me?
:PROPERTIES:
:ID:       6f325ee8-228a-4b05-8ce9-4a997948d46a
:END:
These four sections of [[id:a3bf32ae-8218-48c1-a7d9-a6fd61e5734a][our user manual]] answer this question:

- [[id:fba3642f-b01e-405b-80ac-2900df22e978][Why Emacs?]]
- [[id:e3172459-abcb-45cb-9135-9692f320a836][Why /not/ Emacs?]]
- [[id:46d2058d-249e-45a7-a7a2-58bade48df65][Why Doom?]]
- [[id:da317a3c-1672-40e2-85d5-b4246482af2c][Why /not/ Doom?]]

** How does Doom compare to <insert starter kit>?
I've compiled comparisons to several starter kits in [[id:f2186c7b-9f48-4b0b-ac0b-d891b5b1e1b3][our migration guide]].

** Is Doom a fork of another starter kit?
No. I started Doom from scratch in 2013 to learn Emacs and Emacs Lisp, and to
write a private config for myself. Starter kits were brought to my attention
later, when early Doom users vocally compared them.

That's not to say I've taken no inspiration from them since. Doom's earliest
file structure was inspired by Prelude's, until it was replaced with a module
system. Other concepts (like [[kbd:][SPC]] as a leader key) came from Spacemacs or were
PRed from migrating users, and were accepted because they seemed sensible.

More similarities (and differences) will no doubt emerge as our userbase grows
and more starter kits appear.

** Doom claims to be an Emacs framework, not a starter kit. What's the difference?
I don't claim to own these terms, but I use them to distinguish [[https://git.doomemacs.org/core][Doom's core]] (a
framework) from [[https://git.doomemacs.org/modules][Doom's module library]] (a starter kit).

My premise is: starter kits and Emacs frameworks have different goals. Where
starter kits help you avoid work by doing it for you, an Emacs framework helps
you /do/ that work yourself, but more effectively (by providing extra tools,
APIs, or organizational systems for writing/debugging). Of course, there will be
some crossover.

** Who maintains Doom Emacs?
My name is [[https://github.com/hlissner][Henrik]], I'm this project's author and its sole maintainer, for the
moment. I plan to onboard co-maintainers once the project has:

- Proper technical documentation for users, contributors, and
  maintainers. Many important organizational questions haven't been formally
  answered or committed to paper: such as our versioning scheme, git
  conventions, community policies, and code/documentation style guides. Even
  Doom's goals aren't formally stated anywhere.
- More unit, integration, and package tests. Total coverage isn't required (or
  desired), but Emacs issues are complex and esoteric, so /some/ measure of
  automated sanity checks (and protocols for merges and releases) are needed to
  spare future maintainers a stroll through a minefield.
- Resolved its stability, performance, and standardization issues that plague
  its CLI. Issues too esoteric for me to unleash onto unsuspecting
  co-maintainers in good conscience. I could live with them when Doom was my
  private config, but that is no longer the case. It needs to be rewritten.

Most of these issues will be resolved in the final 3.0.0 release.

I am looking for [[id:29d9a145-8f2e-4d22-b4d0-de8a2c72698d][module maintainers]] though!

** Why is the project called "Doom"?
As a kid in the Cretaceous period (1999), the [[https://github.com/id-Software/DOOM][source code]] of idsoftware's
classic Doom was my first exposure to programming. Totally clueless about C and
compilers, all I could do was peek at it from time to time and hope I'd absorb
its secrets if I stared hard enough. It didn't work, but it sure jump-started by
gamedev addiction.

So "Doom Emacs" was what you got when you combined childhood, demon-carnage
nostalgia, [[https://www.youtube.com/user/n4sco][terrible]] [[https://github.com/hlissner/emacs-solaire-mode][naming]] [[https://github.com/hlissner/vim-forrestgump][sense]], and the sneaking suspicion that Emacs is the
unwritten tenth circle Dante censored for humanity's protection.

I've doomed us all.

** Why does Doom use straight.el and not package.el?
=package.el= simply doesn't cut it. Its flaws become apparent the more packages
you manage, the more complex your config becomes, and how often those packages
see updates:

- No disaster recovery ::
  When things go wrong, we don't always have time to deal with it. Or we need to
  wait for upstream to deploy a fix. While we wait, we still have work to do,
  but now what? Emacs is broken! =package.el= doesn't give you any options to
  roll back, so you /have/ to deal with it, and now. Or hope your old config was
  backed up.

  Though Doom doesn't have a 'doom rollback' command (yet), the ability to
  quickly checkout an old commit of a problematic package (or Doom itself),
  without the overhead of forking and/or maintaining a local copy, is priceless.
- Rolling release or bust ::
  =package.el= installs the latest version of every package, or none at all.
  There's no rollback, no pinning to a stable ref, and no git history to peek
  into. It offers little reproducibility; wiping/losing/copying your config
  becomes a gamble if you aren't constantly backing up your packages (then
  recompiling them if you're up/downgrading Emacs).

  =melpa-stable= was well intentioned, but it offers no guarantees or standards
  on how/when maintainers tag their projects. I'd rather the user decide for
  themselves, because they're the ones in the trenches.
- Can't install packages from superior sources ::
  Often, a crucial fix sits in a pull request somewhere for too long, a package
  becomes outdated through official channels, or a superior fork springs up
  somewhere other than an ELPA. =package.el= cannot reach those sources.
- Slow at startup (by default) ::
  Initializing =package.el= can be expensive, depending on the number (and
  complexity) of installed packages -- especially for batch scripts.
  ~package-quickstart~ helps, up to a point, but Doom's package manager can do
  better with the assumptions available to its monolithic ecosystem. All without
  imposing =straight.el= or =package.el= on your runtime environments.

Package management needs to be easier, because Emacs is hard enough already.
Doom fills these gaps with =straight.el='s help, and beyond.

Granted, you /can/ get most of the above with a little Git know-how, but it
stops being convenient as you reach package 5 or 15, your tenacity permitting.

** Why is startup time important? Why not use the daemon?
It isn't, but it gets a disproportional amount of attention because it's the
first thing Doom's users notice. Doom is perfectly compatible with the daemon
and I don't intend to discourage its use. If I had to say something about it,
it's that I'm unhappy that a daemon is needed at all to get sane startup times
out of Emacs.

It's left to the user to know or care about optimal load paths, and to implement
them, but that's a lot to ask when the problem domain is so vast, esoteric, and
a moving target (with a high cost-to-benefit). Who has the time to inspect, much
less fix, all their packages? And maintain that effort across Emacs or package
updates? It's easier to use the daemon, so people do.

That said, there's no one to blame for that. I consider Doom's effort, the
daemon, even native compilation (though all excellent endeavors) stop-gap
measures for a deeper, underlying issue in Emacs that needs smarter people than
I to address.

Rather than startup time, runtime performance is a bigger priority, though the
two rarely stray far from each other.

** Where do I follow the development of the project?
:PROPERTIES:
:ID:       4af14dad-5b74-43a7-8c9a-153227eed4a9
:END:
Our development resources are listed [[id:a20e3feb-f1e4-4bd3-92a9-6dfb17bcb24b][in our manual]].

** Where do I report issues, request features, or get user support?
Check out [[id:2f277e96-654d-406f-8797-b9a7d2ccc218][our community resources]] for a complete list of communities and
platforms. I'd recommend [[https://discourse.doomemacs.org/get-help][our Discourse]].

** I don't like Discord. Can Doom move to IRC/Telegram/Matrix/other?
This is requested *a lot*--and not always so kindly. We have [[https://discourse.doomemacs.org][a Discourse]] and
[[https://discourse.doomemacs.org/t/a-matrix-space-for-doom-emacs/2664/12][there are plans for a Matrix space]], but that's as many platforms as I have
bandwidth for. Please do not ask me to reconsider.

There is no submission process for FAQs. Our community leaders select them from
our Discord, Discourse, and Github communities (sometimes elsewhere) based on

:END:
For common how-to and configuration questions from Doom users. You'll find more
[[https://discourse.doomemacs.org/tags/faq][on our Discourse]].

** Find out what version of Doom am I running?
Use ~M-x doom/info~ or ~$ doom info~ to produce detailed information about your
installation and environment.

Alternatively, ~M-x doom/version~ or ~$ doom version~ will only list the
versions of installed Doom components.

The installed version of Doom core is also displayed in the Doom dashboard's
mode-line.

** Turn (Doom) Emacs into a <insert language here> IDE with LSP?
:PROPERTIES:
:ID:       4cec77b2-bb1c-4b35-8ad1-d6dd9fcc1dbb
:END:
This is frequently asked: how to transform Doom Emacs into an IDE for some
programming language. In almost all cases, it's recommended that you enable
Doom's LSP support and install a supported LSP client.

This provides code completion, lookup {definition,references,documentation}
functionality, and syntax checking, all in one:

1. Enable Doom's [[doom-module::tools lsp]] module. ([[id:01cffea4-3329-45e2-a892-95a384ab2338][How do I enable modules?]])
2. Enable the ~+lsp~ flag on the ~:lang~ module corresponding to the language
   you want LSP support for. E.g. For python, enable [[doom-module::lang python +lsp]]. For
   rust, enable [[doom-module::lang rust +lsp]]. ([[id:01cffea4-3329-45e2-a892-95a384ab2338][How do I enable module flags?]])
3. Install [[https://emacs-lsp.github.io/lsp-mode/page/languages/][a supported LSP client]] on your system using your OS package manager
   OR from within Emacs using ~M-x lsp-install-server~ (warning: not all servers
   can be installed this way).
4. Run ~$ doom sync~ on the command line.
5. Restart Emacs.
6. (Optional) If Emacs fails to find your LSP server, you may need to run ~$
   doom env~ to regenerate your envvar file (which contains your =$PATH=, which
   tells Emacs where to find programs on your system).

*** Potential issues
1. Some language modules lack LSP support (either because it doesn't exist or
   I'm not aware of it -- let me know!). If you're certain a language is
   supported by [[doom-package:lsp-mode]], simply adding [[fn:lsp!]] to that major mode's hook will be
   enough to enable it:

   #+begin_src elisp
   ;; Remember to replace MAJOR-MODE with the major mode that powers the language.
   ;; E.g. `ruby-mode-local-vars-hook' or `python-mode-local-vars-hook'
   (add-hook 'MAJOR-MODE-local-vars-hook #'lsp! 'append)

   ;; For Elisp gurus: Doom provides MAJOR-MODE-local-vars-hook, and we use it
   ;; instead of MAJOR-MODE-hook because it runs later in the mode's startup
   ;; process (giving other functionality or packages -- like direnv -- time to
   ;; configure the LSP client).
   #+end_src

2. Some languages have alternatives that are superior to the LSP offerings (such
   as Cider for Clojure or Sly for Common Lisp).

When in doubt, check that language module's documentation! Look up a module's
documentation with [[kbd:][<help> d m]] (or ~M-x doom/help-modules~).

** Change my fonts
Doom exposes a couple variables for setting fonts. They are:

- [[var:doom-font]]: the primary font for Emacs to use.
- [[var:doom-variable-pitch-font]]: used for non-monospace fonts (e.g. when using
  variable-pitch-mode or mixed-pitch-mode). Popular for text modes, like Org or
  Markdown.
- [[var:doom-emoji-font]]: used for rendering emoji. Only needed if you want to use
  a font other than your operating system’s default.
- [[var:doom-symbol-font]]: used for rendering symbols.
- [[var:doom-serif-font]]: the sans-serif font to use wherever the [[face:fixed-pitch-serif]]
  face is used.
- [[var:doom-big-font]]: the large font to use when [[fn:doom-big-font-mode]] is active.

Each of these variables accept one of:

- A font-spec object: ~(font-spec :family "FontName" :size 12.0 :weight 'light)~
- An xft font string:
  - Short form: ~"JetBrainsMono-12"~
  - Long form:  ~"Terminus (TTF):pixelsize=12:antialias=off"~
- An XLFD string: ~"-*-Fira Code-regular-normal-normal-*-11-*-*-*-*-*-*-*"~

For example:
#+begin_src emacs-lisp
;; in $DOOMDIR/config.el
(setq doom-font (font-spec :family "JetBrainsMono" :size 12 :weight 'light)
      doom-variable-pitch-font (font-spec :family "DejaVu Sans" :size 13)
      doom-symbol-font (font-spec :family "JuliaMono")
      doom-big-font (font-spec :family "JetBrainsMono" :size 24))
#+end_src

#+begin_quote
 󰐃 If you or Emacs can't find your font, use ~M-x describe-font~ to look them
    up, or run ~$ fc-list~ to see all the available fonts on your system. *Font
    issues are /rarely/ Doom issues!*
#+end_quote

*** To change fonts on the fly:
1. Select your ~setq~ statements,
2. Evaluate them with ~M-x eval-region~ (evil users can use the [[kbd:][gr]] operator to
   evaluate regions of elisp, non-evil users can use [[kbd:][C-x C-e]]),
3. Then reload the fonts: ~M-x doom/reload-font~.

Your changes should take effect immediately.

** Change, customize, or make themes?
- To change themes, add ~(setq doom-theme 'name-of-theme)~ to
  =$DOOMDIR/config.el=.
- To switch themes on-the-fly, type [[kbd:][<help> t]] or ~M-x load-theme~.
- To customize or write themes, see our guide on [[https://discourse.doomemacs.org/t/how-to-switch-customize-or-write-themes/37][the Discourse]].

** Properly update Doom?
You can update Doom one of two ways:

1. The correct way: by running ~$ doom upgrade~ in the shell and restarting
   Emacs.
2. The manual way (if ~doom upgrade~ is broken for some reason):

   #+begin_src bash
   $ cd ~/.emacs.d
   $ git pull       # pull the latest version of Doom's source
   $ doom sync -u   # update Doom's packages and 'doom sync'
   #+end_src

This may change in the future, so ~$ doom upgrade~ will always be the safest
option. That said, ~$ doom help upgrade~ will always document the correct
procedure for manual updates if you need it.

** Bind my own keys (or change existing ones)?
Emacs provides a couple functions to bind keys:

- ~define-key KEYMAP KEY DEF~
- ~global-set-key KEY DEF~
- ~local-set-key KEY DEF~
- ~evil-define-key STATES KEYMAP KEY DEF &rest ...~

However, Doom provides a more general ~map!~ macro, to conveniently wrap up the
above four into a more succinct syntax. Comprehensive examples of ~map!~'s usage
can be found in its documentation (keyboard shortcut: [[kbd:][<help> f map\!]]).

There are also live examples =map!='s usage in
=config/default/+evil-bindings.el=.

Unfortunately, binding keys in Emacs can be a complicated affair. A more
detailed guide on keys, keymaps, and keymap precedence can be found [[https://discourse.doomemacs.org/t/how-to-re-bind-keys/56][on our
Discourse]].

** Change or alias the leader or localleader key?
This is documented in more detail in our user manual:

- [[id:76df34eb-142c-4280-85e7-b231d8adafc5][How to change your leader keys]]
- [[id:58741e77-c44b-4292-b9c9-5eb7da36fa21][How to bind new keys under the leader prefix]]
- [[id:8e0d2c05-6028-4e68-a50d-b81851f3f258][How to bind aliases for your leader / localleader prefix]]

** Change the style of (or disable) line-numbers?
Doom uses the [[doom-package:display-line-numbers]] package, which is included with Emacs 26+.

*** To disable line numbers entirely
#+begin_src emacs-lisp
;;; in $DOOMDIR/config.el
(setq display-line-numbers-type nil)
;; or
(remove-hook! '(prog-mode-hook text-mode-hook conf-mode-hook)
              #'display-line-numbers-mode)
#+end_src

*** To switch to relative line numbers
To change the style of line numbers, change the value of the
~display-line-numbers-type~ variable. It accepts the following values:
#+begin_example
t            normal line numbers
'relative    relative line numbers
'visual      relative line numbers in screen space
nil          no line numbers
#+end_example

For example:
#+begin_src emacs-lisp
;;; add to $DOOMDIR/config.el
(setq display-line-numbers-type 'relative)
#+end_src

You'll find more precise documentation on the variable through [[kbd:][<help> v
display-line-numbers-type]] ([[kbd:][<help>]] is [[kbd:][SPC h]] for [[doom-package:evil]] users, [[kbd:][C-h]] otherwise).

*** To cycle through different styles of line numbers
Use ~M-x doom/toggle-line-numbers~ (bound to [[kbd:][<leader> t l]] by default) to cycle
through the available line number styles in the current buffer.

E.g. ~normal -> relative -> visual -> disabled -> normal~

** Disable Evil (vim emulation)?
By disabling the [[doom-module::editor evil]] module ([[id:01cffea4-3329-45e2-a892-95a384ab2338][how to toggle modules]]).

Read the "[[id:f3925da6-5f0b-4d11-aa08-7bb58bea1982][Removing evil-mode]]" section in the module's documentation for precise
instructions.

** Know when to run ~$ doom sync~?
:PROPERTIES:
:ID:       594d2505-d3cb-4061-ab76-06e7c8a4e0b8
:END:
As a rule of thumb, run ~$ doom sync~ whenever you:

- Update Doom with ~$ git pull~ instead of ~$ doom upgrade~,
- Change your ~doom!~ block in =$DOOMDIR/init.el=,
- Change =autoload.el= or =autoload/*.el= files in any module (or =$DOOMDIR=),
- Change the =packages.el= file in any module (or =$DOOMDIR=).
- Install an Emacs package or dependency outside of Emacs (i.e. through your OS
  package manager).

If anything is misbehaving, it's a good idea to run ~$ doom sync~ first, to rule
out any issues with missing packages or autoloads.

This command is never needed for changes to =$DOOMDIR/config.el=.

** Suppress confirmation prompts when executing a doom command?
~-!~ or ~--force~ are the universal "suppress all prompts" switch for most
=doom= commands.

** Copy or sync my config to another system?
*Short answer:* it is safe to sync =$DOOMDIR= across systems, but not
=$EMACSDIR=. Once moved, use ~$ doom sync && doom build~ to ensure everything is
set up correctly.

*Long answer:* packages can contain baked-in absolute paths and non-portable
byte-code. It is never a good idea to mirror it across multiple systems, unless
they are all the same (same OS, same version of Emacs, same paths). Most issues
should be solved by running ~$ doom sync && doom build~ on the other end, once
moved.

** Start over, in case something went terribly wrong?
Delete =$EMACSDIR/.local/straight= and run ~$ doom sync~.

** Restore the s and S keys to their default vim behavior ([[doom-ref:][#1307]])
[[kbd:][s]] and [[kbd:][S]] have been intentionally replaced with the [[doom-package:evil-snipe]] plugin, which
provides 2-character versions of the f/F/t/T motion keys, ala [[https://github.com/goldfeld/vim-seek][vim-seek]] or
[[https://github.com/justinmk/vim-sneak][vim-sneak]].

These keys were changed because they are redundant with [[kbd:][cl]] and [[kbd:][cc]] respectively
(and the new behavior was deemed more useful).

If you still want to restore the old behavior, simply disable evil-snipe-mode:
#+begin_src emacs-lisp
;; in $DOOMDIR/config.el
(remove-hook 'doom-first-input-hook #'evil-snipe-mode)
#+end_src

** Doom and/or Emacs is slow
:PROPERTIES:
:ID:       643acc75-9717-4739-9c52-3947491e827e
:END:
The answer changes from version to version (of Emacs), and is often updated with
new information, so [[https://discourse.doomemacs.org/t/why-is-emacs-doom-slow/83][this is answered on Discourse]] instead.

** Doom starts up with a vanilla splash screen
The most common cause for this is a =~/.emacs= file. If it exists, Emacs will
read this file instead of the =~/.emacs.d= directory, ignoring Doom altogether.

If this isn't the case, run ~$ doom doctor~. It can detect a variety of common
issues and may offer you clues.

** I see a scratch buffer at startup instead of the dashboard
The common explanations for this are:

- Emacs can't find your private doom config (in =~/.doom.d= or
  =~/.config/doom=). Make sure only one of these two folders exist, and that it
  has an =init.el= file with a ~doom!~ block. Running ~$ doom install~ will
  create these files and directories for you.

- An error occurred while starting up Doom. Use [[kbd:][C-h e]] to inspect Emacs' log.
  Search it for errors or warnings. If you find one, [[id:aa116c29-b7d5-488a-860f-bdb22c1f4e8e][producing a backtrace]] from
  the error can shed more light on it (and will be required if you ask the
  community for help debugging it).

- You have disabled the [[doom-module::ui doom-dashboard]] module. Read about
  [[id:5e267107-81fa-45b4-8ff3-26d4b98e508e][what Doom modules are]] and [[id:01cffea4-3329-45e2-a892-95a384ab2338][how to
  toggle them]].

If you're still stuck, run ~$ doom doctor~. It can detect a variety of common
issues and may give you some clues as to what is wrong.

** Doom fails to find executables (or inherit my shell's =$PATH=)
The three most common causes for =$PATH= issues in Doom are:

1. Your shell configuration doesn't configure =$PATH= correctly. Run ~$ which
   <PROGRAM>~ in your shell. If it doesn't emit the path you expect (or any path
   at all) then you need to modify you shell config to do so correctly.
2. Your app launcher (rofi, albert, docky, dmenu, sxhkd, etc) is launching Emacs
   with the wrong shell, either because it defaults to a different shell from
   the one you actively use or the app launcher itself inherits the wrong
   environment because it is being launched from the wrong shell.
3. You're a Mac user launching Emacs from an =Emacs.app= file. MacOS launches
   these apps from an isolated environment.

As long as your shell is properly configured, there is a simple solution to
issues #1 and #3: generate an envvar file by running ~$ doom env~. This scrapes
your shell environment into a file that is loaded when Doom Emacs starts up. Run
~$ doom help env~ for details on how this works.

For issue #2, you'll need to investigate your launcher. There are too many
launchers write a walkthrough for, you'll have better luck asking about it on
[[https://doomemacs.org/discord][our Discord]] or [[https://discourse.doomemacs.org][Discourse]].

** Changes to my config aren't taking effect
1. Make sure you don't have both =~/.doom.d= and =~/.config/doom= directories.
   Doom will ignore the first if the second exists.
2. Remember to run ~$ doom sync~ after making [[id:594d2505-d3cb-4061-ab76-06e7c8a4e0b8][certain changes]] to your config.
   Run ~$ doom help sync~ to know exactly when you should use it.
3. If you are reconfiguring a package, make sure you've deferred your settings
   until the package loads with the ~after!~ macro:

   #+begin_src emacs-lisp
  (after! magit
    (setq magit-repository-directories '(("~/projects" . 2))
          magit-save-repository-buffers nil))
   #+end_src

   There are two exceptions to this rule:
   #+begin_src emacs-lisp
   ;; Setting file/directory variables don't (and shouldn't be) deferred. e.g.
   (setq org-directory "~/org")

   ;; Don't defer setting variables whose documentation explicitly say they must
   ;; be set *before* the package is loaded. e.g.
   (setq evil-respect-visual-line-mode t)
   #+end_src

If none of these solve your issue, try ~$ doom doctor~. It will detect a variety
of common issues, and may give you some clues as to what is wrong. Otherwise,

** Doom crashes and/or freezes
Here are a few common causes for random crashes:

- Some fonts cause Emacs to crash when they lack support for a particular glyph
  (typically symbols). Try changing your font by changing ~doom-font~ or
  ~doom-symbol-font~.

- Ligatures can cause Emacs to crash. Try a different [[doom-module::ui ligatures +fira][ligature font]] or disable
  the [[doom-module::ui ligatures]] module altogether.

- On some systems (particularly MacOS), manipulating the fringes or window
  margins can cause Emacs to crash. This is most prominent in Doom's Dashboard
  (which uses the margins to center its contents), in org-mode buffers (which
  uses ~org-indent-mode~ to create virtual indentation), or Magit (whose fringes
  are adjusted on the fly).

  There is currently no known fix for this, as it can't be reliably reproduced.
  Your best bet is to reinstall/rebuild Emacs or disable the errant
  plugins/modules.

  E.g. To disable ~org-indent-mode~:
  #+begin_src emacs-lisp
  ;; in $DOOMDIR/config.el
  (after! org
    (setq org-startup-indented nil))
  #+end_src

  Or disable the [[doom-module::ui doom-dashboard]] and [[doom-module::tools magit]] modules (see [[doom-ref:][#1170]]).

If these don't help, check our troubleshooting guides for [[id:f88eaf35-97c4-48de-85ef-2d53f8615d4a][hard crashes]] or

** TRAMP connections hang forever when connecting
You'll find solutions [[https://www.emacswiki.org/emacs/TrampMode#toc7][on the emacswiki]].

** Why do I see ugly indentation highlights for tabs?
[[https://github.com/doomemacs/doomemacs/blob/4eeb3c7a19c324f5a7839a2e3edb03fc87d23034/core/core-ui.el#L97-L116][Doom highlights non-standard indentation]]. i.e. Indentation that doesn't match
the indent style you've set for that file. Spaces are Doom's default style for
most languages (excluding languages where tabs are the norm, like Go).

There are a couple ways to address this:

1. Fix your indentation! If it's highlighted, you have tabs when you should have
   spaces (or spaces when you should be using tabs).

   Two easy commands for that:
   - ~M-x tabify~
   - ~M-x untabify~

2. Change ~indent-tabs-mode~ (~nil~ = spaces, ~t~ = tabs) in
   =$DOOMDIR/config.el=:

   #+begin_src emacs-lisp
   ;; use tab indentation everywhere
   (setq-default indent-tabs-mode t)

   ;; or only in certain modes
   (setq-hook! 'sh-mode-hook indent-tabs-mode t) ; shell scripts
   (setq-hook! '(c-mode-hook c++-mode-hook) indent-tabs-mode t)  ; C/C++
   #+end_src

3. Use [[https://editorconfig.org/][editorconfig]] to configure code style on a per-project basis. If you
   enable Doom's [[doom-module::tools editorconfig]] module, Doom will recognize
   =.editorconfigrc= files.

4. Or trust in [[doom-package:dtrt-indent]]; a plugin Doom uses to analyze and detect indentation
   when you open a file (that isn't in a project with an editorconfig file).
   This isn't foolproof, and won't work for files that have no content in them,
   but it can help in one-off scenarios.

** "The directory =~/.emacs.d/server= is unsafe" error at startup (Windows only)
If you're getting this error you must reset the owner of
=C:\Users\USERNAME\.emacs.d= to your own account:

1. Right-click the =~/.emacs.d/server= directory in Windows Explorer,
2. Click Properties,
3. Select the "Security" tab,
4. Click the "Advanced" button,
5. Select the "Owner" tab,
6. Change the owner to your account name.

([[https://stackoverflow.com/questions/885793/emacs-error-when-calling-server-start][source]])

** My new keybinds don't work
Emacs has a complex and hierarchical keybinding system. If a global keybind
doesn't take effect, it's likely that another keymap is in effect with higher
priority than the global keymap. For example, non-evil users may have tried
something like this, to rebind [[kbd:][C-left]] and [[kbd:][C-right]]:
#+begin_src emacs-lisp
(map! "<C-left>"  #'something
      "<C-right>" #'something)
#+end_src

Just to find that the rebinding had no effect (i.e. [[kbd:][C-h k C-left]] reports that
it's still bound to ~sp-backward-slurp-sexp~). That's because these keys are
bound in ~smartparens-mode-map~. They need to be unbound for your global
keybinds to work:
#+begin_src emacs-lisp
(map! :after smartparens
      :map smartparens-mode-map
      [C-right] nil
      [C-left] nil)
#+end_src

#+begin_quote
 󰐃 I use [C-left] because it is easier to type than "<C-left>", but they are
    equivalent; two different ways to refer to the same key.
#+end_quote
** Recursive load error on startup
If you see an error like:
#+begin_example
Error: error ("Recursive load"
  "/Applications/Emacs.app/Contents/Resources/lisp/jka-compr.el.gz"
  "/Applications/Emacs.app/Contents/Resources/lisp/jka-compr.el.gz"
  "/Applications/Emacs.app/Contents/Resources/lisp/jka-compr.el.gz"
  "/Applications/Emacs.app/Contents/Resources/lisp/jka-compr.el.gz"
  "/Applications/Emacs.app/Contents/Resources/lisp/jka-compr.el.gz"
  "/Applications/Emacs.app/Contents/Resources/lisp/obsolete/cl.el.gz")
#+end_example

Then these are the three most common explanations:

- *GNU* =tar= and/or =gzip= are not installed on your system.

  #+begin_quote
    *Warning macOS and *BSD distro users:* you likely have BSD variants of
      =tar= and =gzip= installed by default. Emacs requires the GNU variants!
  #+end_quote

- =tar= and/or =gzip= aren't in your =$PATH=, somehow. Once you've corrected
  your shell config, run ~$ doom env~ to regenerate your envvar file (containing
  the =$PATH= Doom will see), then restart Emacs.

- *(macOS users only)* You've installed Emacs from one of the sources I
  recommend you avoid. For example, emacsformacosx.com. Our user manual outlines
  where you should acquire Emacs from.

The project does not have a dedicated support team -- only one overworked
[[doom-user:hlissner][meatball]] and a handful of busy volunteers -- so there may be delays processing
your PR. Sometimes this is unavoidable, but there are some measures you can take
to mitigate these delays:

- Ensure there are no open PRs that tackle the same issue. If yours is intended
  to replace an existing one, please mention it.
- Include an explanation: why the PR is necessary, what it fixes, any gotchas I
  should be aware of, and issues it affects.
- Be acquainted with our [[id:46442b23-a7ae-44ba-afdb-b7ba8bb76b6e][git commit conventions]]. Good commit etiquette is
  required. Do not be afraid to rebase or force-push to tidy up your PR, once it
  is ready for review.
- Adhere to our [[id:b3d85a53-a544-44e5-9353-06e413bd7f30][code]], [[id:9bb17259-0b07-45a8-ae7a-fc5e0b16244e][documentation]], and [[id:cc55968b-f430-45e4-9e05-4c6187871b9d][keybind]] conventions, where applicable.
- Ensure you've targeted the =master= branch.
- Keep your PR focused. It shouldn't do too much in too many places, if that can
  be avoided.
- If your PR introduces new tools, dependencies, or packages, I'm going to test
  them. It takes time to research them, acquire them, learn how to use them, and
  finally test them in the context of your PR. You can speed this up by
  including steps to set up an MVE with some mock inputs and expected results.

  Extra points if you supply a =shell.nix= or =Dockerfile= to do so (if
  applicable).

** My PR was approved but not merged, what gives?
I approve PRs in bulk, often days before merging them. This is done to:

- Allow me to merge them when I have time to respond to regressions they may
  cause.
- Give me a second chance to catch issues,
- Give the submitter extra time to correct mistakes,
- Give users a change to test it themselves,

If your PR was approved, you only have to wait for Henrik to get off his
glorious Canadian behind and merge it. If it's been a week or so with no
progress, feel free to ping him in-thread or [[https://doomemacs.org/discord][on Discord]] (in the #contributing
channel).

Due to the sheer complexity of Emacs, our issue tracker receives many
false-positive, redundant, vague, or "support request"-type issues. This is a
problem because they pollute our search results, make it difficult for users and
maintainers to track real issues, and cost much effort to process; taking away
time from real issues or project development.

Since Doom's "support team" only consists of one overworked maintainer and a
handful of busy volunteers, we have to be strict; we don't have the capacity to
chase issues that aren't *actionable*, *immediately reproducible*, or *cannot be
investigated within a reasonable amount of time* (which includes issues that are
poorly researched, vague, or open-ended).

Posts that fall into these categories will be immediately closed, tagged for
deletion, and given a brief explanation why, including instructions to overturn
or contest the ruling if I've made a mistake.

Some examples:
- Performance issues without a clear, verifiable, or reproducible cause.
- Behavior that can't be reproduced in [[id:04f91253-a92a-4125-a576-44de226582bb][vanilla Doom]].
- Behavior that can be reproduced in vanilla Emacs.
- An open-ended request to improve something without concrete goals.
- An issue that consists solely of "X doesn't work" and little else.
- An issue that omits important information, like steps to reproduce or system
  information.
- A post asking how to configure or use Emacs to achieve some effect (our issue
  tracker is for bug reports, not support; ask on [[https://doomemacs.org/discord][Discord]] or [[https://discourse.doomemacs.org][Discourse]] instead).
- A convoluted and unfocused issue that present multiple issues in one.
- A rude user that won't meet us half way and/or expects us to do all the work
  for them.

Consider becoming my [[https://github.com/sponsors/hlissner][Github sponsor]]. If you're not a fan of Github sponsorship,
my page lists a couple alternatives.

If you do decide to sponsor me, thank you for your support! It is a big help,
and directly translates to more hours on my Doom, Emacs-related, or open-source
capers.

** How do I claim my tier rewards?
Once you have sponsored, you'll receive an automated email telling you how, but
in case you didn't: email me at contact@henrik.io or DM me on Discord
(@Henrik#0666) with *your github username* and (optionally) *Discourse

Yes! By becoming a module maintainer, community moderator, or regular you get
the same perks as sponsors [[https://github.com/sponsors/hlissner][on the 25/mo tier]]. Here's what they do:

- *Module maintainers* look after one or more Doom modules. They become my
  consultants for that module(s)' ecosystem, packages, and implementation, and
  issues about them. Some Emacs Lisp expertise is helpful, but it's more
  important that you are knowledgeable about your chosen module's ecosystem.
- *Moderators* look after our Github, Discord, and/or Discourse communities.
  They keep our issue tracker, github projects, and repos organized, and they
  keep the peace by warning/banning bad actors. They're held to a higher
  standard, however, as they represent us.
- *Regulars* are pillars of our community; they're folks that frequent our
  Discord and/or Discourse, are active, helpful, and friendly. This is the only
  role you can't apply for, but we keep a eye out for folks to give it to!

** What is the difference between "first shake" and "first priority"?
Some of my Sponsor tier rewards offer "first shake" or "first priority" on open
issues/feature requests. To explain what these mean:

- Issues that get *first shake* get triaged and investigated before other
  issues, and if it can be resolved in one sitting, I will.
- Issues that get *first priority* get entirely resolved before I move on to
  anything else.

That said, the exception to these rules are issues that are extraordinarily
difficult, outside my expertise, or depend on other development efforts to
resolve.

Folks that depend on Doom for their work or businesses would benefit from
getting first priority, to ensure their issues are resolved ASAP. Or check out
[[https://github.com/sponsors/hlissner?frequency=one-time&sponsor=hlissner][my one-time tiers]] to hire me for dedicated support.

For questions regarding Doom's code design, defaults, or conventions.

** Why does Doom sharp-quote function symbols?
~#'symbol~ is short for ~(function symbol)~, the same way ~'symbol~ is short for
~(quote symbol)~.

I use it to indicate to the byte-compiler (or human readers) that a symbol will
be treated as a function rather than literal data.

However, at runtime, the sharp-quote serves no functional purpose like it does
in other lisps. ~(funcall 'some-function)~ will function identically to
~(funcall #'some-function)~. The sole difference is at compile-time: the
byte-compiler performs additional checks on function symbols and will warn if a
function isn't known to be defined where it's used.

There's more about quoting [[https://emacsdocs.org/docs/elisp/Quoting][in the Emacs manual]].

** Why does Doom not use dash, f, s, or similar libraries?
=subr-x=, =seq=, =map=, =pcase=, and =cl-lib= are all built into Emacs and,
since Emacs 27.1 (the minimum version Doom supports), have made Dash and co
(mostly) redundant. One of Doom's goals is to prefer native functionality where
possible or trivial. That said, many third-party packages depend on them, so
chances are they are already installed on your system.

** Why does Doom discourage the use of ~M-x customize~?
=Customize= exists so that you don't need to be a Lisp programmer to configure
Emacs. It's helpful to beginners (with both configuration and discovery), but I
think it should only serve as a stopgap until you are comfortable writing and
navigating Emacs Lisp, then abandoned. Here's why:

- The way it applies its settings (through theme variables) defies conventional
  load order, which is troublesome to support in middleware like Doom (or user
  configuration) when lazy loading is involved.

- I don't see many instances in the wild where this load-order quirk is
  accommodated. I think this is because those writing/offering that code are
  Lisp programmers, who don't use =Customize= and may not be exposed to its
  quirks, but for beginners this is frustration waiting to happen.

- =Customize= works flawlessly if it is the sole source of truth for your Emacs
  configuration, but /all/ Emacs configs eventually take on Lisp. At this point
  you acquire a second source of truth that =Customize= is happy to (quietly)
  override.

- Without its /unparalleled/ extensibility, I believe Emacs isn't particularly
  interesting or effective software. And =Customize= exposes only a superficial
  portion of that extensibility. Learning Lisp is inevitable if you want to deal
  with issues or tweak where =Customize= can't, and Doom wants to help you face
  Lisp, rather than work around it. Otherwise, you may be happier using modern,
  better polished, and less-DIY competitors.

- =Customize='s commands are safe for read-only use (e.g. to browse/search
  settings), but I'm not convinced it can be compete with Emacs'
  self-documentating facilities. For example, its library of ~describe-*~
  commands already set the bar pretty high.

All that said, I take no steps to disable or cripple =Customize= in Doom
(besides a warning here and there, and hiding it in some menus where it is known
to cause issues). If used sparingly, you may not even run into these issues.

** Why no =expand-region= for evil users (by default)?
I believe [[doom-package:expand-region]] is redundant with and less precise than evil's text
objects and motions.

- There's a text object for every "step" of expansion that expand-region
  provides (and more).
  - To select the word at point = [[kbd:][v i w]]
  - symbol at point = [[kbd:][v i o]]
  - line at point = [[kbd:][V]]
  - the block at point (by indentation) = [[kbd:][v i i]]
  - the block at point (by braces) = [[kbd:][v i b]]
  - sentence at point = [[kbd:][v i s]]
  - paragraph = [[kbd:][v i p]]
  - etc.
- Selection expansion can be emulated by using text objects consecutively: [[kbd:][v i w]]
  to select a word, followed by [[kbd:][i o]] to expand to a symbol, then [[kbd:][i b]] expands to
  the surrounding brackets/parentheses, etc. There is no reverse of this
  however; you'd have to restart visual mode.

The [[doom-package:expand-region]] way dictates you start at some point and expand/contract until
you have what you want selected. The vim/evil way would rather you select
exactly what you want from the get go. In the rare event a text object fails
you, a combination of [[kbd:][o]] (swaps your cursor between the two ends of the region)
and motion keys can adjust the ends of your selection.

#+begin_quote
 󰐃 There are also text objects for xml tags ([[kbd:][x]]), C-style function arguments
    ([[kbd:][a]]), angle brackets, and single/double quotes.
#+end_quote

This is certainly more to remember compared to a pair of expand and contract
commands, but text objects (and motions) are the bread and butter of vim's modal
editing paradigm. Vimmers will feel right at home. To everyone else: mastering
them will have a far-reaching effect on your effectiveness in vim environments.
I highly recommend putting in the time to learn them.

That said, if you aren't convinced, it is trivial to install [[doom-package:expand-region]] and
binds keys to it yourself:
#+begin_src emacs-lisp
;;; in $DOOMDIR/packages.el
(package! expand-region)

;;; in $DOOMDIR/config.el
(map! :nv "C-=" #'er/contract-region
      :nv "C-+" #'er/expand-region)
#+end_src

** Why ~doom env~ instead of ~exec-path-from-shell~?
For some context: there are scenarios where Emacs launches in an isolated
environment where it cannot see your =$PATH= or other needed environment
variables. This affects macOS users (all =Emacs.app= bundles launch Emacs in an
isolated environment), Linux users who misconfigure their launchers to use the
wrong shell, or Windows users who may have no shell environment at all.

[[doom-package:exec-path-from-shell]] was written to mitigate this, by polling the shell at
startup for those environment variables. ~$ doom env~ was written as more
reliable (and slightly faster) substitute. Here's why it's better:

1. [[doom-package:exec-path-from-shell]] must spawn (at least) one process at startup to scrape
   your shell environment. This can be slow depending on the user's shell
   configuration and may fail on non-standard shells (like =fish=). A single
   program (like =pyenv= or =nvm=) or config framework (like =oh-my-zsh=) could
   all our startup optimizations in one fell swoop.

2. [[doom-package:exec-path-from-shell]] takes a whitelist approach and captures only =$PATH= and
   =$MANPATH= by default. You must be proactive in order to capture all the
   envvars relevant to your development environment and tools.

   ~$ doom env~ takes the blacklist approach and captures all of your shell
   environment. This front loads the debugging process, which is nicer than
   dealing with it later, while you're getting work done.

That said, if you still want [[var:exec-path-from-shell]], it is trivial to install
yourself:
#+begin_src emacs-lisp
;;; in $DOOMDIR/packages.el
(package! exec-path-from-shell)

;;; in $DOOMDIR/config.el
(require 'exec-path-from-shell)
(when (display-graphic-p)
  (exec-path-from-shell-initialize))
#+end_src

** Why =ws-butler= over =whitespace-cleanup= or =delete-trailing-whitespace=?
I believe [[doom-package:ws-butler]] is less imposing on teammates/project maintainers; it only
cleans up whitespace on the lines you've touched.

You know the story: a PR with 99 whitespace adjustments around a one-line
contribution. Why? Because they added [[fn:delete-trailing-whitespace]] (or
[[fn:whitespace-cleanup]]) to [[var:before-save-hook]], which mutates entire buffers.

Automated processes that mutate entire files (or worse, whole projects) should
be deliberately invoked, and by someone privvy to the consequences, rather than
automated. =ws-butler= achieves that balance by only cleaning whitespace on
lines that you have modified since opening the file.
