Emacs configuration file

TODOS

  • Paket exec-path-from-shell, um PATH aus Linux auch in emacs zu haben

First start

When pulling the repository the first time, an initial init.el needs to be setup. After start it will replace itself with the configuration from init.org

(require 'org')
(find-file (concat user-emacs-directory "init.org"))
(org-babel-tangle)
(load-file (concat user-emacs-directory "init.el"))
(byte-compile-file (concat user-emacs-directory "init.el"))

This function updates init.el whenever changes in init.org are made. The update will be active after saving.

  (defun me/tangle-init ()
    "If the current buffer is 'init.org',
  the code blocks are tangled, and the tangled file is compiled."
    (when (equal (buffer-file-name)
		 (expand-file-name (concat user-emacs-directory "init.org")))
      ;; avoid running hooks
      (let ((prog-mode-hook nil))

      (load-file user-init-file))))

Magit

Little crash course in magit:

  • magit-init to init a git project

  • magit-status (C-x g) to call the status window

In status buffer:

  • s stage files

  • u unstage files

  • U unstage all files

  • a apply changes to staging

  • c c commit (type commit message, then C-c C-c to commit)

  • b b switch to another branch

  • P u git push

  • F u git pull

Installation 

sudo su
cd /opt
python3 -m venv beancount
source ./beancount/bin/activate
pip3 install wheel
pip3 install beancount
sleep 100
echo "shell running!"
deactivate

  (use-package beancount

To support org-babel, check if it can find the symlink to ob-beancount.el

  orgpath=`find /home/marc/.emacs.d/elpa/ -type d -name "org-plus*" -print`
  beansym="$orgpath/ob-beancount.el
  bean="/home/marc/Archiv/Programmierprojekte/Lisp/beancount-mode/ob-beancount.el"

  if [ -h "$beansym" ]
  then
    echo "$beansym found"
  elif [ -e "$bean" ]
  then
    echo "creating symlink"
    ln -s "$bean" "$beansym"
  else
    echo "$bean not found, symlink creation aborted"
  fi

Fava is strongly recommended.

cd /opt
python3 -m venv fava
source ./fava/bin/activate
pip3 install wheel
pip3 install fava
deactivate

Start fava with fava my_file.beancount

It is accessable on this URL: Fava Beancount-mode can start fava and open the URL right away.
