How to specify global-environments with constraints?

setup-pixi/README.md

Lines 151 to 157 in 33be5ba

	### Global Environments
	You can specify `pixi global install` commands by setting the `global-environments` input argument.
	This will create one environment per line, and install them.
	This is useful in particular to install executables that are needed for `pixi install` to work properly.
	For instance, the `keyring`, or `gcloud` executables. The following example shows how to install both in separate global environments.
	By default, global environments are not cached. You can enable caching by setting the `global-cache` input to `true`.

it is unclear how to install something the equivalent to pixi global install 'cmake <4.0' given that

      - name: Set up Pixi
        uses: prefix-dev/setup-pixi@v0.9.4
        with:
          run-install: false
          global-environments: |
            "cmake <4.0"

errors out with

Error:   × invalid package name '"cmake': '"cmake' is not a valid package name. Package names can only contain 0-9, a-z, A-Z, -, _, or .
    ╰─▶ '"cmake' is not a valid package name. Package names can only contain 0-9, a-z, A-Z, -, _, or .

and

      - name: Set up Pixi
        uses: prefix-dev/setup-pixi@v0.9.4
        with:
          run-install: false
          global-environments: |
            cmake <4.0

errors out with

  Error:   × missing package name

What is the proper syntax that I'm missing?

👋 Gentle ping to @pavelzw (given the commit history on action.yml).

wouldn't something like cmake<4.0 solve your issue?

setup-pixi splits arguments on spaces (i don't want to build a bash-like quote parser into setup-pixi. thus, something like cmake <4.0 would be the bash equivalent of pixi global install "cmake" "<4.0" which will error in the same way.

Ah thanks @pavelzw. I will give this a try soon.

I was expecting to need to follow recipe syntax with the required space of package <x.y.z. Would you be open to a PR that adds an example with version constraints?

[pavelzw]

Yes feel free to create one, thanks!
