If there is a way to automatically get a list of all ConTeXt commands

be happy to improve omni-completion for ConTeXt in Vim.
All is in xml files (i-*.xml) in the distribution maintained by
Wolfgang. We ship with this for editors:
dir t:\texmf\context\data
04/21/2021 11:40 AM <DIR> scite
04/21/2021 11:40 AM <DIR> textadept
04/21/2021 11:40 AM <DIR> texworks
04/21/2021 11:40 AM <DIR> vscode
these lists are generated by mtx-interface so we can add more if needed
Could you please elaborate on the (automatic?) data flow from ConTeXt's
source files to data files for each application? Is it:
source code -> XML -> .lua -> mtx-interface -> data?
In particular, it is not clear to me how i-*.xml files are related to
mtx-interface, as the latter does not use them directly, AFAICS.
for sure it does
in the early days of context mkii we had \startsetups kind of
definitions that got filtered from the source but when xml support was
built that moved to an xml file
then Wolfgang did an excellent job on checking each xml snippet and
added many more and these i-* files showed up, we extended the xml a
bit, redid the rendering of these lists etc
wolfgang is in charge of this so when something specific in the files is
needed ...
Anyway, mtx-interface seems exactly what I am looking for, and I would
like to use it to generate ConTeXt keywords for Vim. Can I patch that
script?
basically we only need
function flushers.vim(collected)
end
For MetaFun keywords I don't know yet: do those XML files contain enough
information about the content of all mp-* source files? E.g., the fact
that `hlingrid` is a def? Looking at the Scite files, I see only
internals and commands, and they seem to cover only the "main" MetaFun
names.
it is still on the agenda to make xml files for metafun but there is no
timeline for that
now, when it comes to highlighting, the reference is the scite one
(which supports several of the languages that we use, and also supports
mixed lua/mp/tex/... lexing) ... right from the start the way it shows
up in an editor determined how the user interface evolved ... believe it
or not, but for a long time we used texedit (written in modula, was
pretty ok in 640K mem, also fast and one could scroll files in the
sidebar and see them instantly; it used the character based windowing
i'd written as a student for terminals connected to a dec vax .. just
for fun ... i'm that old) ... when modula disappeared i actually rewrote
that one in perl/tk and it still works but then decided to use scite
anyway, so scite is still my reference (i looked to vscode but seeing
all this extra stuff, the need for 'servers', the lack of simply running
a command based on suffix ... not now)
that said, we can support whatever editor one uses makes much sense (one
should really use the editor, word processor, operating system etc one
feels most comfortable with) so just make a prototype (or tell me what
kind of lists you need, because it's rather trivial to generate them)
I have used a custom script in the past for fine-grained keyword
extraction from MetaFun's source code. By fine-grained, I mean that the
output contains information about the kind of keyword (def, primary def,
vardef, constant, variable, etc.) I could update it to Lua and mp-*.mpxl
if that interests you—unless that has already been done, of course.
just look at the files in the scite path ... much info is available, for
context it comes from the xml files, for the tex engine and meta* it
comes from mult* lua files
adding more detail (not sure if distinguishing between def and vardef
makes sense ... we more use the 'primitive', 'lowlevel', 'interface'
kind of grouping
let's see what Wolfgang thinks of it ...
