This is a rewrite/continuation of the following modules:
markdown-inline-graphvizpython-markdown-graphvizmarkdown-dot
At some point in the development of python-markdown the original method that these modules used to embed Graphviz was broken because the way it inserted the rendered SVG was dumb (see:).
I have poorly reimplemented the original functionality with the BlockProcessors class, this is a bit finnicky with the parsing of blocks (sometimes you need to use double newlines). But it is more robust than using the Preprocessor method.
I did not implement the PNG rendering functionality because I don't use it. If you want to make significantly smaller documents you might wish to implement SVGZ with the original PNG method from python-markdown-graphviz.
Because this uses the special {% %} syntax, it should be compatible with Jinja and other platforms that recognise it as such, however this is untested.
- Run
setup.py installor put this folder in your $PYTHONPATH - Add
markdown-graphviz-svgto your extensions list in ReText's configuration - Use like this:
{% dot
digraph G {
rankdir=LR
Earth [peripheries=2]
Mars
Earth -> Mars
}
%}
Where dot can be any of: dot, neato, fdp, sfdp, twopi, circo.
- Sometimes the block parser doesn't think you have made a separate block. Insert two newlines above and below your code block to fix it.
- If you don't insert an ending
%}, the parser will eat the rest of your document. I am not fixing this.
