# You can move it here ~/.config/elvish/lib/hx.elv
# Or add `eval (slurp < ~/$REPOS/helix/contrib/completion/hx.elv)`
# Be sure to replace `$REPOS` with something that makes sense for you!
### Renders a pretty completion candidate
var candidate = { | _stem _desc |
edit:complex-candidate $_stem &display=(styled $_stem bold)(styled " "$_desc dim)
}
### These commands will invalidate further input (i.e. not react to them)
var skips = [ "--tutor" "--help" "--version" "-V" "--health" ]
### Grammar commands
var grammar = [ "--grammar" "-g" ]
### Config commands
var config = [ "--config" "-c" ]
### Set an arg-completer for the `hx` binary
set edit:completion:arg-completer[hx] = {|@args|
var n = (count $args)
if (>= $n 3) {
# Stop completions if passed arg will take presedence
# and invalidate further input
if (has-value $skips $args[-2]) {
return
}
# If the previous arg == --grammar, then only suggest:
if (has-value $grammar $args[-2]) {
$candidate "fetch" "Fetch the tree-sitter grammars"
$candidate "build" "Build the tree-sitter grammars"
return
}
# When we have --config, we need a file
if (has-values $config $args[-2]) {
edit:complete-filename $args[-1] | each { |v| put $v[stem] }
return
}
}
edit:complete-filename $args[-1] | each { |v| put $v[stem]}
