**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 Links - - ## Multiple cursors

## Other packages - **rainbow-mode.el:** 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](https://www.emacswiki.org/info-ref?find=Interlocking) in the [EmacsManual](https://www.emacswiki.org/emacs/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.`` - edit `/etc/ImageMagick-7/policy.xml` and comment out - `` # TODOs - Org / global configuration - Page formatting - Modify HTML styling - Printed page layout, white styled figures - Custom export function for HTML and $\LaTeX$, with; - `Shift` - ``, `Shift` - `` 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.
