Hi,

I tried to write one some time ago but it seems my knowledge of ConTeXt was
insufficient. I gave up. I also think it would be nice.

If I can recall, one of the first problems I ran into concerned how ConTeXt
environments work (among other things I cannot recall). In LaTeX, you have
something like:
\begin{theorem}
When you are writing the grammar, you can clearly separate the tokens into
'\', 'begin', '{' and '}'. So you get a consistent object that the
tree-sitter library can work with. But with ConTeXt, you have something
like this:
\startTheorem
We know that it is actually made up of '\', 'start' and 'Theorem'. But
there is nothing separating the latter two so I couldn't find a way to make
it general enough across board because of how configurable ConTeXt is (we
have very few pre-defined environments). So I went with \start[theorem]. I
am very sure it was my skill but just some thoughts from someone who tried
in the past.

Maybe we could benefit from pre-converting the source file to an XML-like
tree before applying the grammar? At which point you are venturing into LSP
territory...
