Tracking issue: language support requests

[clason]

This is a tracking issue collecting requests for new languages to add to nvim-treesitter. If you would like to add a language to the list, comment on this issue with the following information:

• name of the language
• link to an existing tree-sitter parser (if available)
• link to a repository containing queries (if available)
• language grammar description, vim syntax plugin etc. if none of the above exist.

Note: having a language on this list does not mean a maintainer will do the work for adding it; rather this list is meant as guidance for community contributions.

---

Languages needing a PR

(Parsers and simple queries exist already and just need to be included in our list and tested.)

• Proto (Support for protobuf #2307)
• Solidity (Add support for solidity #1168)
• SQL (add sql syntax parser #2511)
• org (Support org files #2841)
• TJ's Neovim-specific Lua parser (What would it take to use my lua grammar :) #543)
• ReScript
• gotmpl

Languages needing queries

(A parser exists, but queries for highlights, indent, injections, folds, and/or locals are still missing. Some guidance for writing these can be found in CONTRIBUTING.md and the tree-sitter documentation.)

• Agda (Agda #1431)
• Objective-C (Anyone interested in an Objective-C parser? #1824)
• Vimdoc (feat: add vimdoc parser and queries #2679)

Languages needing parsers

(Not even a parser exists yet; if you are familiar with the language and tree-sitter, consider contributing one. You can also help by searching for new parsers in case someone has created by now.)

• luadoc (comments with emmyLua annotations; similar to jsdoc/phpdoc)
• htmldjango/jinja2
• ASCIIdoc (request: Asciidoc support ? #2263)
• zsh (zsh support (need a parser of its own) #655)

Haxe

• Syntax (described with OCaml): https://github.com/HaxeFoundation/haxe/tree/development/src/syntax
• Vim syntax plugin: https://github.com/jdonaldson/vaxe
• LSP: https://github.com/vshaxe/haxe-language-server
• Official site: https://haxe.org/

Haxe also has a tree-sitter implementation here:

FSharp

EDIT: @baronfel 's parser is now archived, points to this one instead
Current Parser
It doesn't appear that anyone has done any queries
Language spec's

I would love to contribute, but frankly all of this is WAAAAY over my head.

Jenkinsfile

In addition to groovy's syntax, there are additional keywords added by jenkins that would be common on a Jenkinsfile:

OpenSCAD

My parser for this seems to be feature complete: https://github.com/bollian/tree-sitter-openscad

I'm willing to maintain support for my parser. Currently I'm looking for guidance on how to write the queries and modules for supporting highlighting, folding, and indentation.

GDB

I Want to use https://github.com/LiadOz/nvim-dap-repl-highlights with c++, I set up nvim-dap to use GDB, but it has no syntax highlighting. There is basic syntax highlighting for gdb in vim, but not for tree-sitter, which is what the plugin requires. It would also help with editing ~/.gdbinit

Nftables

The scripting interface for writing Nftables firewall rules.

Existing Vim plugin: https://github.com/nfnty/vim-nftables
Reference: https://wiki.nftables.org/wiki-nftables/index.php/Quick_reference-nftables_in_10_minutes

There is no available parser yet.

KCL

https://kcl-lang.io/ - constraint-based, functional configuration language.

tree-sitter parser: https://github.com/kcl-lang/tree-sitter-kcl
Neovim plugin: https://github.com/kcl-lang/kcl.nvim

WIT

[fwrs]

iCalendar (.ical, .ics, .ifb, .icalendar)

RFC5545: https://datatracker.ietf.org/doc/html/rfc5545#section-3.1
Something fairly simple to just differentiate the keys and values and also "BEGIN"/"END" blocks would be really nice

Sourcepawn

tree-sitter parser: https://github.com/nilshelmig/tree-sitter-sourcepawn
link to a repository containing queries: https://github.com/nilshelmig/tree-sitter-sourcepawn

Idris2

tree-sitter parser: https://github.com/gwerbin/tree-sitter-idris2/tree/master
queries: not found

Typst

Typst: Typst Docs Parser: tree-sitter-parser Grammar can be found in the readme of the parser

Don't know if there's a repository containing queries

EDIT from @theHamsta:

• WIP repo https://github.com/SeniorMars/typst.nvim
• alternative grammar https://github.com/frozolotl/tree-sitter-typst
• Helix issue Is there any plan to support typst? helix-editor/helix#6688

Upon feature comparison, the ideal parser would be uben0/tree-sitter-typst#7 (comment) instead. Queries are being worked on by @Nagefire at https://github.com/Nagefire/nvim-treesitter/tree/feat/typst. So this request should be updated.

[Freed-Wu]

https://github.com/rush-rs/tree-sitter-asm:

The nvim-treesitter plugin does not include this parser.

Is it possible to add it?

[clason]

This list has become unmanageable, so I'm closing and locking it.

Resolution

• List of parsers is now maintained at https://github.com/nvim-treesitter/nvim-treesitter/wiki/List-of-parsers
• If you are willing to maintain the queries, just open a PR adding an entry to the list and (at least) a basic highlight query.
• If a parser is missing in the list, reach out on Matrix or -- if you must -- open a discussion (which will be closed afterwards).
• Do not open requests for languages which do not have a parser; this is out of scope for this project.
