Rust Shebang Is Not Highlighted Correctly

[orhnk]

Summary

#!/usr/bin/env run-cargo-script

one on the left is neovim (the correct one) right one is helix

Reproduction Steps

create a rust file (ending with '.rs') and open it with helix.

add a shebang which is generally represented as:

#!/usr/bin/env run-cargo-script

Helix log

You have to define a shebangs key in your languages.toml for Rust, i.e.

helix/languages.toml

Line 616 in 9a65118

shebangs = ["sh", "bash", "dash", "zsh"]

Is your nvim setup using nvim-treesitter for rust highlighting?

I don't see anything in tree-sitter-rust for parsing the shebang so this would require a change upstream there

[orhnk]

No, I don't use nvim-treesitter for highlighting. If you are interested, here is my neovim config file

This is my current Rust language section:

# Rust
[[language]]
name = "rust"
scope = "source.rust"
injection-regex = "rust"
file-types = ["rs"]
roots = ["Cargo.toml", "Cargo.lock"]
auto-format = true
shebangs = ["run-cargo-script"]
language-server = { command = "rust-analyzer" }
formatter = { command = "rustfmt" }
indent = { tab-width = 2, unit = "  " }

I wonder does it serve a purpose as an auto shebang generator? (Or even is there any)
