* My dotfiles
The config files are organized in emacs org files. They are tangled
and symlinked to the appropriate directories.

[[file:emacs-init.org::*tangle%20dotfiles][A hook]] tangles all files automatically on each save.
~emacs-init.org~ is special and not automatically tangled. The >100 src
blocks make tangling take several seconds and ~org-babel-load-file~ in
~init.el~ tangles the init org file on each emacs start anyway.

For now the symlinks need to be created by manually running the
appropriate src block in each configuration file.

** Git Setup
Every program's configuration lives in its own branch. All branches
except the ones which end with a plus sign are then merged into
=master=. To keep the git history clean, I use this script:

#+begin_src shell :shebang "#!/bin/bash" :tangle tangle/merge.sh
git checkout master
git reset --hard init
git branch -a | grep -v -e +$ -e master | sed "s/[ *] //" | xargs git merge
git push --force origin master
#+end_src

** Updating all tangled files
This script (re-)tangles all =.org= and =.org.gpg= files. Run this in
case the org files were updated outside of your local emacs (e.g.
after pulling from a remote). Make sure to run it from the dotfiles
directory.

#+begin_src shell :shebang "#!/bin/bash" :tangle no
emacs --batch --eval="\
  (progn (require 'org)
         (let ((org-confirm-babel-evaluate nil))
           (mapc 'org-babel-tangle-file (split-string \"$(ls *.org *.org.gpg)\"))))"
#+end_src

The above won't quite work for me as I use ~org-crypt~ in some
configuration files and it also needs to be loaded & setup. For
details see [[file:emacs-init.org][emacs-init.org]].

#+begin_src shell :shebang "#!/bin/bash" :tangle tangle/tangle.sh
emacs --batch --eval="\
  (progn (require 'org)
         (require 'org-crypt)
         (org-crypt-use-before-save-magic)
         (setq org-tags-exclude-from-inheritance '(\"crypt\"))
         (setq org-crypt-key \"F1EF502F9E81D81381B1679AF973BBEA6994521B\")
         (defun save-without-hook ()
           (let ((before-save-hook nil))
             (save-buffer)))
         (setq org-babel-pre-tangle-hook '(org-decrypt-entries save-without-hook))
         (advice-add 'org-babel-tangle :after '(lambda (&rest r)
                                                 (org-encrypt-entries)
                                                 (save-without-hook)))
         (let ((org-confirm-babel-evaluate nil))
           (mapc 'org-babel-tangle-file (split-string \"$(ls *.org *.org.gpg)\"))))"
#+end_src

* Window manager
I use [[https://github.com/ch11ng/exwm][exwm]] and [[https://awesomewm.org/][awesome]] as my window managers. When doing a lot of
coding and similar stuff I tend to use exwm as I will spend most of my
time in emacs anyway.
