Uses the smiley system instead of the img system to display formula
This has interesting enhancements:

- First smiley text stays available for copy, hence copy of the image,
copies the smiley text
- Second since smileys are cached, (using a checksum hash table), latex
formula are not calculated twice
- Third, this allows future implementation to actually send the custom
smiley to the peer (to be done)
- Forth, the buffer string does not get modified (simpler parsing
function)

Here’s its page

- This will remove the use of the script (so to make it usable under win32 for instance)

- This patch removes the script usage, .tex file is now generated directly from the C code,
and latex is directly called. There still is the convert call (which still implies the imagemagik dependency, but that’s a WIP)

Temporary files are now created in a temporary directory (using tmpnam), script is no longer used so deleted

- This patch stack on the two preceding patches and allow convert to be configured

“WTF?” you might ask. And you are right in doing so. The usefulness of this becomes clear immediately to people who dislike how their gnuplot plots look when imported as bitmap into a LaTeX document. The fonts aren’t right, lines look wishy-washy, etc. And even if you do get these right, once you change the fonts in your document you have to redo all plots. The gnuplot-lua-terminal solves these issues by using PGF/Tikz. PGF/Tikz is a drawing library for LaTeX. Simply put, your gnuplot plot is translated into a list of LaTeX commands which make sure to use the right fonts, line widths, etc., to achieve a seamless fit into your LaTeX document.

MINI-HOWTO:

start gnuplot

Then in the terminal run:

and then use some pdf viewer to look at the result. The default settings of the Lua terminal create a tex file without preamble, etc, so you can include it in your document. With the “fulldoc” option we get a complete LaTeX source including preambel, etc.. Have a look at the included documentation for more info.

Example:

Here you can find an example output.
