Hi! This is the staged-recipes linter and your PR looks excellent! 🚀

[conda-forge-admin]

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/outlines-core/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipes/outlines-core/meta.yaml:

• ℹ️ Jinja2 variable references are suggested to take a {{<one space><variable name><one space>}} form. See lines [25].

Completes the difficult half of #27820, hopefully...

    Could not find openssl via pkg-config:
    Could not run `PKG_CONFIG_PATH=/home/conda/staged-recipes/build_artifacts/outlines-core_1737141988511/_h_env_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placehold_placeho/lib/pkgconfig PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags openssl`
    The pkg-config command could not be found.

    Most likely, you need to install a pkg-config package for your OS.
    Try `apt install pkg-config`, or `yum install pkg-config`,
    or `pkg install pkg-config`, or `apk add pkgconfig` depending on your distribution.

    If you've already installed it, ensure the pkg-config command is one of the
    directories in the PATH environment variable.

    If you did not expect this build to link to a pre-installed system library,
    then check documentation of the openssl-sys crate for an option to
    build the library from source, or disable features or dependencies
    that require pkg-config.

    cargo:warning=Could not find directory of OpenSSL installation, and this `-sys` crate cannot proceed without this knowledge. If OpenSSL is installed and this crate had trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the compilation process. See stderr section below for further information.

    --- stderr


    Could not find directory of OpenSSL installation, and this `-sys` crate cannot
    proceed without this knowledge. If OpenSSL is installed and this crate had
    trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
    compilation process.

    Make sure you also have the development packages of openssl installed.
    For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

    If you're in a situation where you think the directory *should* be found
    automatically, please open a bug at https://github.com/sfackler/rust-openssl
    and include information about your system as well as this message.

    $HOST = x86_64-unknown-linux-gnu
    $TARGET = x86_64-unknown-linux-gnu
    openssl-sys = 0.9.104


    It looks like you're compiling on Linux and also targeting Linux. Currently this
    requires the `pkg-config` utility to find OpenSSL but unfortunately `pkg-config`
    could not be found. If you have OpenSSL installed you can likely fix this by
    installing `pkg-config`.

I am working on the same package at #28863

Do you want to switch over there and I add you as maintainer?

[maresb]

Woah cool! Add me after approval to not slow things down?

If you comment on the PR (#28863) I will add you there. If you don't, I'll do it once the feedstock has been created.

Closing in favor of #28863

[maresb]

@hadim, may I ask what's your interest in outlines? Are you using it directly?

I'm on a team that wants to use vllm, and that's a bit of a mess to get running with conda-forge.

[hadim]

I don't have any specific project with it. I wanted to give it a try myself and thought having it on c-f would be a good thing.
