Escaping with /BTEX ... /ETEX

[hmenke]

It would be cool if one could escape to ConTeXt within /BTEX ... /ETEX like for regular typing. This is extremely useful for annotating code. Currently only automatic escaping in comments works.

\usemodule[vim]

\definevimtyping
  [python]
  [syntax=python,
   escape=on]

\starttext

\starttyping[escape=yes]
# Returns /BTEX\m{\sum_{i=1}^{n}i}/ETEX
def sum_upto(/BTEX\m{n \in \mathbb{N}}/ETEX)
    r = range(1, /BTEX\m{n}/ETEX + 1)
    return sum(r)
\stoptyping

\startpython
# Returns \m{\sum_{i=1}^{n}i}
def sum_upto(\m{n \in \mathbb{N}}w)
    r = range(1, \m{n} + 1)
    return sum(r)
\stoppython

\stoptext

This was also asked on the context mailing list, so I'll copy-paste my reply from there:

Short answer. No.

Long answer. t-vim relies on vim to syntax highlight the code. Since the code is not valid python, the default python syntax highlighting will not work. In principle, it is possible to write a vim syntax highlighting script for a derivative of python where math terms are allowed, but that requires a lot of work for each language. The whole point of t-vim module was that I am lazy and don't want to write the parser for each language :-)

Thank you for taking the time to implement this! Maybe you should mark this as fixed now.

I am embarrassed to say that I forgot that you had raised this issue. As I said in my previous message (and also repeat in my blog post), I always thought that the implementation will be ugly. So, all thanks to Cristoph who wrote a clean implementation of this feature.
