Text editor support via Digestif

Text editor support via Digestif

[Augusto Stoffel]

Hi all,

I have worked a bit on ConTeXt support in the Digestif language server
[1], and I think it's pretty usable by this point, so I would like to
invite everyone to check it out. Feedback is welcome.

Digestif plugs into any editor that support the Language Server
Protocol, and provides the usual IDE features: completion (of
commands, keyword arguments, references, citations), go to definition,
find references, document outline, etc. Among the fancier features is
fuzzy-matching, so you can, say, find a citation by typing parts of the
title or author names (and get away with using meaningless BibTeX
identifiers).

The newest (git) version reads the ConTeXt interface files at runtime,
so it should be pretty accurate, and also work with third-party
packages. It would be cool to also have some integrated
documentation, but it looks like ConTeXt (or TeX in general) doesn't
have anything of help in this direction currently, right?

Another nice thing is that Digestif is a Lua program, and can run on
the LuaTeX interpreter with no extra dependencies. On the other hand, I
didn't get the change to test it on Windows or editors other than
Emacs, although both things should work with minimal adjustments. Let
me know if you have any issues.

Best,

Augusto

this looks great. Thanks a lot for this.

Unfortunately I get

Company mode enabled in current buffer
Yas minor mode enabled in current buffer
eglot--connect: Symbol’s function definition is void: project-root

when I activate eglot in emacs.

Using

(require 'company-lsp)
(add-to-list 'company-lsp-filter-candidates '(digestif . nil))

Using lsp-mode I get

progn: Symbol’s value as variable is void: company-lsp-filter-candidates

for

(add-to-list 'company-lsp-filter-candidates '(digestif . nil))

I have no experience with using either eglot or lsp-mode. So I am afraid
that I have to adjust something more than written on your Github page.

Thanks a lot for your work on digestif and improving ConTeX support!

I'd probably like to use it with SublimeText which I favour over VScode...

I'd have to revive ST's package which provides support for ConTeXt syntax and
now trying it with vim/coc, but wonder whether you're using TeXLive or lmtx? 

I'm trying with the latter on Debian (Sid)...

I have only tested it with TeXLive. But if lmtx provides a lua interpreter
with kpathsea bindings, like the usual texlua, then it will surely work. If
that's not the case and you installed lmtx in a nonstandard location, you
will need to set an environment variable to specify the location of the
interface XML files.

Best,
Augusto

you can use resolvers.findfile when you use

mtxrun --script yourscript ...

OK.

I've installed it into ~/opt/lmtx and context-en.xml is at

opt/lmtx/tex/texmf-context/tex/context/interface/mkiv/context-en.xml

Which variable should be set?

You would set DIGESTIF_TEXMF to the (list of) directory(ies) containing 
the ls-R file(s).

However, I gather from Hans's comment that lmtx does not have the ls-R 
files. So something lmtx-specific has to be added to Digestif.

Best,
Augusto
