custom pygments style detected but ignored only in minted #299

Hi,

I'm running an up-to-date debian unstable. I installed base16-pygments by running pip3 install pygments-base16.

When I try the following: xelatex -shell-escape -halt-on-error main.tex on this file :

\documentclass[12pt]{article}

\usepackage{minted}
\usemintedstyle{base16-onedark}

\begin{document}
  \mintinline{ocaml}{let f x = Some x}
\end{document}

It produces a file with default minted color scheme. It doesn't use the specified base16-onedark.

If I change the name to something that doesn't exist like fjesfkljesklfjklesf, I have a proper error:

(./_minted-main/default-pyg-prefix.pygstyle)Could not find style module 'fjesfkljesklfjklesf'.
system returned with code 256

So, minted finds that my style exists but just seems to ignore it. So I asked myself : maybe the style is wrong ?

I tried to call pygments myself, using: pygmentize -f html -O full,style=base16-onedark -l ocaml -o out.html code.ml on this file:

let f x = Some x

I checked the result with xdg-open out.html and the color scheme is the right one.

OK, maybe minted is just ignoring all my styles ? So I changed the \usemintedstyle{base16-onedark} to \usemintedstyle{monokai} (monokai is installed by default with pygment on my system) and this one is working.

So for some reasons, minted knows that base16-onedark exists (otherwise it would fail saying it can't find it) but ignores it completely and I can't see why...

Everything works fine with pygmentize so I believe the issue comes from minted. Do you have any clue ?

Cheers.

minted can't use any styles whose names contain characters besides a-z,A-Z, plus - and _. This ultimately goes back to the characters that LaTeX allows in (normal) macro names, plus a little customization. So the numbers in the style name are causing failures...I'm surprised this didn't result in an error message.

There is an existing issue (https://github.com/gpoore/minted/issues/294) that, when resolved, should fix this as well. I have no idea when that will be possible, however.

For now, your best option if you really need the alternate style is to create a custom copy with a name that doesn't involve numbers.
