oils-container

YSH and OSH shells in a container

Build

Install buildah and podman.

Available releases are listed at https://www.oilshell.org/releases.html

Choose a release version, its checksum, and set a tag for your image.

version="0.22.0"
checksum="7ad64ad951faa9b8fd310fc17df0a93291e041ab75311aca1bc85cbbfa7ad45f"
image_tag="quay.io/chroot.club/oils:v${version}-debian"

Run the following command.

buildah unshare ./container.sh $version $checksum $image_tag

Or do this if you have ysh on your workstation.

buildah unshare ./container.ysh $version $checksum $image_tag

An unshare session is required, because our container.sh script mounts the root filesystems of two working containers. This operation would require root privileges otherwise. See man buildah-unshare.

Usage

Oils is actually two shells

• osh - a new POSIX-compatible shell implementation to run your existing scripts
• ysh - a brand new shell language with better defaults, structured data types, and more

Currently, both shells are implemented by the oils-for-unix binary, and are invoked via symlinks. The language (YSH or OSH) is chosen at runtime based on whether ysh or osh is invoked.

Anyway, do one of these.

podman run --rm quay.io/chroot.club/oils:v0.22.0-debian osh -c 'echo hi from a POSIX shell'
podman run --rm quay.io/chroot.club/oils:v0.22.0-debian ysh -c '
    var wow = { native: ["json", "support"] }
    echo "omg a new shell with"
    json write (wow)
'
