Convenience methods for using dot2tex to make latex figures

[mpharrigan]

We use graphviz. There exists a package dot2tex that can generate latex code and/or pdf figures from graphviz. This has the benefit of supporting latex math. Here's a little code snippet. I had to hack into the call graph drawer code to use sympy.printing.latex so the dot file contains raw latex-math

def to_latex_pdf(g, fn_prefix):
    dot = GraphvizCallGraph(g, edgelabel_fmt='latex').get_graph()
    with open(f'{fn_prefix}.dot', 'w') as f:
        f.write(dot.to_string())

    subprocess.check_call(['dot', '-Txdot', f'-o{fn_prefix}.xdot', f'{fn_prefix}.dot'])
    subprocess.check_call(['dot2tex', '-traw', f'{fn_prefix}.xdot', '-o', f'{fn_prefix}.tex'])
    subprocess.check_call(['pdflatex', f'{fn_prefix}.tex'])
    subprocess.check_call(['pdfcrop', f'{fn_prefix}.pdf', f'{fn_prefix}.pdf'])

The motivation is to draw latex figures for the call graph; correct?

[mpharrigan]

yes. conceivably this could be used for the decomposition-graph as well

Sadly, dot2tex says it's unmaintained and does not support the tables-within-nodes we use for the costing graphs. You can use the existing code to write an SVG file but it won't render latex math
