Is it possible to list all supported project.platforms targets from the pixi CLI API?

[matthewfeickert]

With pixi project platform list it is possible to list all of the platforms supported in a particular pixi project.

Example:

$ pixi --version
pixi 0.26.1
$ pixi project platform help
Commands to manage project platforms

Usage: pixi project platform [OPTIONS] <COMMAND>

Commands:
  add     Adds a platform(s) to the project file and updates the lockfile [aliases: a]
  list    List the platforms in the project file [aliases: ls]
  remove  Remove platform(s) from the project file and updates the lockfile [aliases: rm]
  help    Print this message or the help of the given subcommand(s)

Options:
      --manifest-path <MANIFEST_PATH>  The path to 'pixi.toml' or 'pyproject.toml'
  -v, --verbose...                     Increase logging verbosity
  -q, --quiet...                       Decrease logging verbosity
      --color <COLOR>                  Whether the log needs to be colored [env: PIXI_COLOR=] [default: auto] [possible values: always, never, auto]
      --no-progress                    Hide all progress bars [env: PIXI_NO_PROGRESS=]
  -h, --help                           Print help
$ pixi project platform list  # in the same directory as an example pixi project
Environment: default
- win-64
- linux-64
- osx-arm64
- osx-64

Is it possible from the pixi CLI API to output all supported pixi project platforms by a particular version of pixi?

Use case

You're demonstrating that by adding to the project.platforms key that you can solve the environment across multiple platforms at the same time. During the demonstration you're asked "How do I know what are the valid platform identifiers (i.e. target values)?". Ideally it would be nice to provide a CLI API method to get these, if it doesn't already exist.

Currently not through the cli. You will get the list of options when you are using a wrong one. e.g.

❯ pixi project platform add matthew
  × 'matthew' is not a known platform. Valid platforms are 'noarch', 'unknown', 'linux-32', 'linux-64', 'linux-aarch64', 'linux-armv6l', 'linux-armv7l', 'linux-ppc64le', 'linux-ppc64', 'linux-s390x',
  │ 'linux-riscv32', 'linux-riscv64', 'osx-64', 'osx-arm64', 'win-32', 'win-64', 'win-arm64', 'emscripten-wasm32', 'wasi-wasm32', 'zos-z'

Ah great. Thanks for this example.

The length of this list I think is truly an impressive feat that should be celebrated! :D
