Variadic Args

{@} forwards leftover recipe CLI args to the recipe cmd.

[recipes.test]
cmd = 'go test "{pkg}" {@}'

[recipes.test.arguments.pkg]
type = "rel_path"
position = 1
required = true
values = "@go-packages"

Run it with:

shadowtree test ./internal/recipe -run=TestResolve -count=1

The typed positional value supplies {pkg}. The leftover flags are spliced at {@} as separate shell-quoted words.

Rules

{@} is supported only in cmd.
In shell command strings, it must occupy a whole shell word.
It is not available in pre, post, or sync_out.
For typed recipes, positional values and known key=value values are consumed by typed arguments and excluded from {@}.
Unknown identifier key=value tokens remain errors.
Command flags such as -run=TestName pass through.

Use -- after typed recipe arguments to pass the following argv literally to {@}, including option values that contain =:

shadowtree test pkg=./internal/recipe -- --flag NAME=value
