Hi,
I have two questions with the vim module.
1. I want to use the math mode inside the code. I've seen the escape option,
e.g. here [1], but this seems to work only with comments. Is there a
possibility to use it directly in the code, too?
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
:-)
Minimal example:
```
\usemodule[vim]
\definevimtyping[python][syntax=python, escape=on]
\starttext
\startpython
# Returns \m{\sum_{i=1}^{n}i}
def sum_upto(\m{n \in \mathbb{N}})
r = range(1, \m{n} + 1)
return sum(r)
\stoppython
\stoptext
```
Another option will be to use the algorithmic module:

2. It would be cool, if I can define some background color for the code.
Unfortunately I'm very new to context and haven't seen a direct option. I
assume this is possible with some kind of extra environment around the code?
You can add
\setupbackground[background=color, backgroundcolor=gray]
\setupvimtyping[python]
[
before={\startbackground},
after={\stopbackground},
]
or, instead of modifying the default background, define a new background
and use that.
