**Important**
- For **Gnuplot** source blocks: Do not use `%` inside Gnuplot source
block but `\%` or in format command `\%%`
- % starts a comment in LaTeX and therefore stops further
interpretations like a closing bracket `}` etc.
- Gnuplot graphics are imported as .tex (text, axis, legend) and
.eps (figure) files.
- `\%` `\%%` can also be used for HTML SVG export

## Other packages
- **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.
<a id="information"></a>
# 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](https://www.emacswiki.org/info-ref?find=Interlocking) in the [EmacsManual](https://www.emacswiki.org/emacs/EmacsManual) for details.
<a id="errors"></a>
# Errors
- failed execution of bibtex2html
- see bib2htmlxxxxxx.blg for errors, e.g.
- I couldn&rsquo;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.``
- edit `/etc/ImageMagick-7/policy.xml` and comment out
- `<policy domain="delegate" rights="none" pattern="gs" />`
<a id="todos"></a>
# TODOs
- Org / global configuration
- Page formatting
- Modify HTML styling
- Printed page layout, white styled figures
- Custom export function for HTML and \(\LaTeX\), with;
- `Shift` - `<f5>`, `Shift` - `<f6>` with open file
- delete temp. generated export files
- Figures
- Gnuplot
- plot transposed files/tables
- preamble in function and call this function for every gnuplot block either
manually or automatically with a hook?!
- 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:
- Preamle: `#+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]`
