lukas Comments - Answer Overflow

Hey, I was looking at the codebase yesterday and noticed a comment about Mojo not being able to use functions in CFFI. You can pass mojo functions right to cffi callbacks, you just can’t pass null pointers

Ah I hadn't considered publishing the python bindings. Is there a specific use case you have in mind that the bindings would be able to accomplish?

That’s an interesting question. Maybe when magic gets a little better I’ll write a Mojo wrapper around the C and publish

It's mostly all working, aside from a few corner cases in the tree sitter grammar

Ah I haven't put it up yet since I'm still tweaking a lot, but I can publish it with a YMMV warning I guess

It should just be the same as how I added struct. Pr for that is welcome. I also should add tests

I’m probably gonna start on __mlir_op sometimes this weekend or next week. It’s tricky to get right since it requires custom grammar parsing and not just a highlight token. At least that’s what it requires if we want more granular control over things like bracket vs plain backtick

Yep, that’s what I’m doing (except I’m using Zed in the above which might have slightly different tree sitter setup)

I’m not sure how I want to highlight dialect names though. Or builtins

We’ll probably have to patch in some of the newer syntax/tree sitter stuff. Lately I’ve been playing with special highlighting for MLIR stuff

Ooh wait, is there a tree sitter grammar for MLIR? We could have it so that things like:

__mlir_op.`1: i1`

__mlir_op.`1: i1`

uses MLIR syntax highlighting injection within the backticks

FWIW this is my helix config and it works for me

[language-server.mojo-lsp]
command = "mojo-lsp-server"
config = { provideFormatter = true }

[[grammar]]
name = "mojo"
source = { git = "https://github.com/lsh/tree-sitter-mojo", rev = "e645ad097257a29bed5ee6213fef47e26b280f63" }

[[language]]
name = "mojo"
grammar = "mojo"
scope = "source.mojo"
roots = ["__init__.mojo"]
file-types = ["mojo", "🔥"]
indent = { tab-width = 4, unit = " " }
auto-format = true
language-servers = ["mojo-lsp"]
formatter = { command = "mojo", args = ["format", "-q", "-"]}
