Release Notes

✨ Highlights

This release brings in numerous improvements and bug fixes and one big feature: argument variables tasks!
By specifying the args key in your manifest, you will have a more convenient way of specifying arguments, which works with pipes and even allows you to set defaults.

Let's say you define this manifest:

[tasks.install]
cmd = "cargo install {{ type }} --path {{ path }}"
args = ["path", { arg = "type", default = "--release" }] # `path` is mandatory, `type` is optional with a default

Both of the invocations now work, since type is optional:

pixi run install /path/to/manifest
pixi run install /path/to/manifest --debug

If you don't specify args for your tasks everything which you append to the CLI will also be appended to the task.

[tasks.install]
cmd = "cargo install"

Therefore, running pixi run install --debug --path /path/to/manifest will lead to cargo install --debug --path /path/to/manifest being run inside the environment.
This was already the behavior before this release, so existing tasks should continue to work.
