I am learning how TeXmacs uses plugin styles. Just as a test, I modified /usr/local/share/TeXmacs/plugin/python/packages/session/python.ts adding letters A and B to macro python-output like this:
<assign|python-output|<\macro|body>
<\with|mode|text|language|verbatim|font-family|tt>
<\generic-output>
A<arg|body>B
</generic-output>
</with>
</macro>>
expecting these letters to show up in python output, but nothing happened. Thinking that this might have something to do with style caching, I ran texmacs --delete-style-cache, but nothing changed. What am I missing?
