This is an ongoing evolution of Emacs configuration files, inspired by a bunch of online resources.

Installation

Different ways to install:

1. If emacs-conf is available in a custom pacman repository

   pacman -S emacs-conf
   ln /opt/emacs-conf/init ~/.config/emacs/
   ln /opt/emacs-conf/early-init.el ~/.config/emacs/
   

2. Download or clone git repo and point the emacs init (and early-init.el) file to this configuration.

3. (Old) Run one of the following install script commands (using curl, wget or fetch).

   sh -c "$(curl -fsSL http://gitea.weseng.de/daniel/emacs/raw/master/scripts/install.sh)"
   sh -c "$(wget -O- http://gitea.weseng.de/daniel/emacs/raw/master/scripts/install.sh)"
   sh -c "$(fetch -o - http://gitea.weseng.de/daniel/emacs/raw/master/scripts/install.sh)"
   

   Installation path is ~/.config/emacs. See details and other installed linux packages as requirements inside sripts/install.sh.

Packages

General key bindings and functions

• C-r (query-replace-regexp) replace text
• C-x RET f (set-buffer-file-coding-system) e.g. set to =utf-8

• (diff-buffer-with-file) show a diff between buffer (current state) and file (saved state)

Information

Interlock symlinks and auto-save files. Be aware that symbolic links of the form “.#*” are not auto-save files but interlocks to prevent the simultaneous editing of the same file. See Interlocking in the EmacsManual for details.

Errors

• failed execution of bibtex2html
  • see bib2htmlxxxxxx.blg for errors, e.g.
    • I couldn’t open style file acmu.bst
  • copy/merge the texmf directory into your home directory.
• when using this in an Org mode buffer: #+HEADER: :fit yes :imagemagick yes :iminoptions -density 300
  • can leads to:
    • convert: attempt to perform an operation not allowed by the security policy `gs' @ error/delegate.c/ExternalDelegateCommand/378.
    • convert: no images defined `DESY_logo_tikz.png' @ error/convert.c/ConvertImageCommand/3282.

#+LATEX_HEADER: \newcommand\hcancel[2][black]{\setbox0=\hbox{$#2$}%
#+LATEX_HEADER: \rlap{\raisebox{.45\ht0}{\textcolor{#1}{\rule{\wd0}{1pt}}}}#2}

    • hcancel: [\"{\\\\setbox0=\\\\hbox{$#2$}\\\\rlap{\\\\raisebox{.45\\\\ht0}{\\\\textcolor{#1}{\\\\rule{\\\\wd0}{1pt}}}}#2}\",2]
