depythontex nested \py enviroment

[Cadair]

In my document I have the following LaTeX code:

    \begin{subfigure}[b]{\fwidth}
        \py[fluxTD]|get_pgf_include(fnames[3])|
        \caption{\py[fluxTD]|captions[3]|}
        \label{fig:TD_flux_r30_4}
    \end{subfigure}

which works fine under pythontex but when I run depythontex I get the following error:

* DePythonTeX error:
    Could not find command "py" on line 512

Do you have any suggestions on how I could fix this in depythontex?

The solution to this is to make the \py environment print out the \caption environment.

I assume this limitation of depythontex extends beyond my limited use case however,

depythontex works fine with normal environments, but the subfigure environment provided by the subcaption package is using a minipage environment internally, and I believe this throws off the line numbering. depythontex currently relies on line numbers to locate the commands it is replacing, since this reduces the potential for false positives. I will need to look into a more advanced system for dealing with these sorts of cases.

I will put a note about this limitation in the next release. In more complex cases with depythontex, it is simpler to generate larger chunks of text on the Python side, rather than using a lot of interspersed \py commands.

I believe this is the first issue specifically related to depythontex. If you don't mind me asking, what sort of situation are you using it for? I haven't put much development time into depythontex since getting the first version working, because it's worked for my limited use cases. But if it is starting to get more use, I might consider improving it sooner rather than later.

Sorry for the slow response.

I am, in this case using PythonTeX for writing a paper manuscript here. I needed dePythonTeX to make a source file I could send to the journal.

Thanks for the link! Seeing how others are using depythontex gives me a better sense of how it may be improved.
