[question][Conan 2.0] what's the correct way of obtaining the list of settings for a package in conancenter?

[mkmkme]

What is your question?

In 1.X, you could see the available options for the upstream package at least by search the full reference:

❯ conan search 'sdl/2.26.1@' -r conancenter
...
    Package_ID: f4055e5fd18060c3b0e30bed926e054dcb4524ab
        [options]
            alsa: True
            arts: False
            directfb: False
            esd: False
            fPIC: True
            iconv: True
            jack: False
            libunwind: True
            nas: True
            opengl: True
            opengles: True
            pulse: True
            sdl2main: True
            shared: False
            sndio: False
            video_rpi: False
            vulkan: True
            wayland: True
            x11: True
            xcursor: True
            xinerama: True
            xinput: True
            xrandr: True
            xscrnsaver: True
            xshape: True
            xvm: True
...

I couldn't find any way to get the list of options in 2.0. I need that in order to understand how can I configure the dependencies for my project.

Have you read the CONTRIBUTING guide?

You can get pretty similar results with conan list (As in, conan search is just an alias for list over all remotes), by specifying that you want info for all the packages of a reference, like so: (And maybe adding a --formater=json in case you need to parse this output from another script)

$ conan list "zlib/1.2.13:*" -r conancenter
conancenter
  zlib
    zlib/1.2.13

Doesn't work for sdl:

❯ conan list 'sdl/2.26.1:*' -r conancenter

  sdl
    sdl/2.26.1

Oh, yes, sorry about that, I didn't look at the recipe itself. With Conan 2 being out for just a few weeks, some recipes are not yet migrated to the newer version, and so won't show packages in Conan v2, because none has yet been built for it.

Luckily, sdl2 has a few PRs in the pipeline to migrate it, namely conan-io/conan-center-index#16266. Once merged, packages for sdl will show up with their options. We just opened the CI services from a planned maintenance, so the backlog of PRs that the CI needs to process has increased a bit, but it should get addressed shortly™️

[mkmkme]

I see. Thanks!
I wonder if it's worth converting this issue to a feature request and make it so you don't need to figure out those options from actually compiled packages in conancenter :)

I do have a workaround for this with

conan download sdl/2.26.1 --recipe-only
conan inspect $(conan cache path sdl/2.26.1)

and luckily I can make it a custom subcommand for myself with 2.0 features. Although I wish I didn't have to, and having such information without need to download recipe first sounds like a good feature :)

[AbrilRBS]

Recent work for conan list formatters have made the output of conan list easier to understand - If a different approach is wanted, we'd be happy to accept custom commands in conan-extensions, closing as solved! :)
