tree-sitter-prr

This is a fork of the-mikedavis/tree-sitter-diff that basically just adds a > in front of every line.

I did this because I wanted to try out the mailing-list-style-code-review-tool-for-GitHub, prr, but wanted to have syntax highlighting in Helix.

Usage in Helix

Update your languages.toml with the following:

[[language]]
name = "prr"
scope = "source.prr"
roots = []
file-types = ["prr"]
injection-regex = "prr"

[[grammar]]
name = "prr"
source = { git = "https://github.com/bcspragu/tree-sitter-diff", rev = "3390ef2dce6c749900a9dca72671b06c83d2bc59" }

And then run hx --grammar fetch && hx --grammar build. I had to do a bunch of manual chown-ing because the Arch AUR helix-git package puts everything in /usr/lib/helix, which is owned by root.

Example

I swear it works, here's a diff of a random Helix PR I loaded with prr get helix-editor/helix/4079:
