merge: rewrite-docs

I've omitted docs/*.org from this merge, as there is still work left to
do there, but I am pushing the module docs early so folks can benefit
from the new docs sooner.

* Description
* Description :unfold:
This module enables support for a literate config.
A literate config consists of a =DOOMDIR/config.org=. All src blocks within are
tangled =DOOMDIR/config.el=, by default, when ~doom sync~ is executed.

This module only requires a =$DOOMDIR/config.org=, which will be tangled into
=$DOOMDIR/config.el= when you run ~$ doom sync~.

* Configuration
** Change the location of config.org
The ~+literate-config-file~ variable controls where to look for your config.org.
To change this it must be modified early -- in =DOOMDIR/init.el= or
=DOOMDIR/cli.el=.
To change this it must be modified early -- in =$DOOMDIR/init.el= or
=$DOOMDIR/cli.el=.
Source blocks needs to be in some language to be automatically tangled, for
example ~#+BEGIN_SRC elisp~, but it doesn't matter what language is used. All
blocks are tangled to ~config.el~, but ~elisp~ gives correct syntax
example ~#+begin_src emacs-lisp~, but it doesn't matter what language is used.
All blocks are tangled to ~config.el~, but ~elisp~ gives correct syntax
highlighting. If you don't want to specify language in block you can also
enforce tangling by adding ~#+BEGIN_SRC :tangle yes~
enforce tangling by adding ~#+begin_src :tangle yes~
** Change where src blocks are tangled or prevent it entirely
By default, this module tangles all src emacs-lisp blocks to config.el unless
otherwise specified.
To specify otherwise use the =:tangle= parameter to:
To specify otherwise use the ~:tangle~ parameter to:
- Specify a destination other than config.el: ~:tangle packages.el~
- Disable tangling of the block altogether with ~:tangle no~
- Or force non-elisp src blocks to tangle somewhere
For example:
#+BEGIN_SRC org
,#+BEGIN_SRC elisp :tangle no
#+begin_src org
,#+begin_src emacs-lisp :tangle no
(message "Don't tangle me")
,#+END_SRC
,#+end_src
,#+BEGIN_SRC elisp :tangle packages.el
,#+begin_src emacs-lisp :tangle packages.el
(package! my-package)
(package! other-package)
,#+END_SRC
,#+end_src
,#+BEGIN_SRC sh :tangle ~/.dotfiles/bin/script.sh :tangle-mode (identity #o755)
,#+begin_src sh :tangle ~/.dotfiles/bin/script.sh :tangle-mode (identity #o755)
#!/usr/bin/env bash
echo Hello world
,#+END_SRC
,#+end_src
,#+BEGIN_SRC sh :tangle ~/.dotfiles/bin/script.sh :shebang "#!/usr/bin/env bash"
,#+begin_src sh :tangle ~/.dotfiles/bin/script.sh :shebang "#!/usr/bin/env bash"

/There are no known problems with this module./ [[doom-report:][Report one?]]
* Frequently asked questions
[[doom-suggest-faq:][Ask a question?]]
** How do I tangle to =$DOOMDIR/init.el=?
If your literate needs are more complex (e.g. you want to make your init.el
literate), this module won't cut it. =init.el= is loaded long before
=config.org= is tangled in the ~doom sync~ process.
literate), this module won't cut it. =init.el= files in modules are loaded long
before =config.org= is tangled in the ~$ doom sync~ process.
However, Doom comes with a [[file:../../../bin/org-tangle][bin/org-tangle]] script which can be used to tangle
arbitrary org files from the command line. Use it to create your own compilation
workflows. This is /much/ faster than using ~org-babel-load-file~ directly to
load your literate config every time Doom is started.
** How to disable tangle-on-save
** How do I disable tangle-on-save?
There are occasions where tangling on save may be undesirable. Maybe it's too
slow, produces too much noise, or happens too often (on unrelated org files in
your =DOOMDIR=). This behavior can be disabled with:
#+BEGIN_SRC elisp
;; add to DOOMDIR/config.el
your =$DOOMDIR=). This behavior can be disabled with:
#+begin_src emacs-lisp
;; add to $DOOMDIR/config.el
