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

Installation

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

Or 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.

Usage

See the emacs command my-help for some key-bindings and further commands and information.

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
(decode-coding-region) e.g. decode to utf-8 (郭富城Aaron Kwok)

rainbow-mode.el :: https://elpa.gnu.org/packages/rainbow-mode.html rainbow-mode is a minor mode for Emacs which displays strings representing colors with the color they represent as background.

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.

TODOs

Org / global configuration
- Page formatting
  - Modify HTML styling
    - Printed page layout, white styled figures
Figures
- Gnuplot
  - plot transposed files/tables
Tables
- Wrap Table in div element. For smartphone scrolling.
Table of contents
- $\LaTeX$; currently headers with no-number property means not included in TOC
- HTML; currently generated list, like lot and lol, are not included in toc but own headers without numbers are.
Equation cancel/strike out with color line
- hcancel[color]{}
- Example: $\hcancel[red]{f_{X_2}(x_2)}}$
- Definition:
  - Preamble: #+LATEX_HEADER: \usepackage{cancel}
    #+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]
