earthlyls = { command = "earthlyls" }

[[language]]
name = "earthfile"
scope = "source.earthfile"
injection-regex = "earthfile"
roots = ["Earthfile"]
file-types = [
  { glob = "Earthfile" },
]
comment-token = "#"
indent = { tab-width = 2, unit = "  " }
language-servers = ["earthlyls"]

[[grammar]]
name = "earthfile"
source = { git = "https://github.com/glehmann/tree-sitter-earthfile", rev = "2a6ab191f5f962562e495a818aa4e7f45f8a556a" }

Optionally run hx --grammar build to update your tree-sitter libraries and get the Earthfile syntax highlighting.

Performance

How fast?

On a macbook air m1, earthlyls loads the 178 Earthfile in the earthly repository — approximately 10000 lines — in 51.95ms. A simple "go to definition" runs under a millisecond. A "go to reference", which searchs in all the Earthfile in the workspace, runs in 18.61ms.
