[O] example filter for code blocks?

Hi everyone,

I have an idea for putting links in a pdf that would open python code blocks in an editor. To do that, I need to modify what happens when an org-file is published to latex.

Essentially I want it to do exactly what it already does in terms of running pygments, and making nicely formatted and syntax highlighted code blocks and output.

After that though, I want to tangle the code block to a file in a directory, and insert a new link after the rendered code block. I would prefer not to have to put :tangle headings in each code block because there are many (e.g. hundreds) of them in course notes. It would be sufficient if they were just sequentially numbered as dir/1.py, dir/2.py, etc... and it is fine if these get overwritten on each export.

the link that would go after the code block in the latex export would be something like:
\LaunchPython{dir/1.py}{Open code}

Then clicking on it would open dir/1.py in whatever editor your system is configured for. \LaunchPython is a newcommand I have defined that works already.

It seems like the new export engine should make this easy to do, but I am not sure where to start. Could anyone point me to a starting place? Thanks!
