monoceros add-language

Adds a language toolchain to a workbench’s config. The toolchain is installed into the container on the next monoceros apply.

monoceros add-language <name> <lang>[:version] [--yes]

<lang> is a catalog language (node, python, java, go, rust, dotnet, …). Append :version to pin one; omit it for the catalog default.

Examples

monoceros add-language acme go            # catalog default
monoceros add-language acme java:21       # pin a version
monoceros add-language acme python:3.12

Languages with extra options Monoceros surfaces (e.g. Java’s Maven/Gradle) are written as an editable object you can tweak in the yml:

languages:
  - java:
      version: '21'
      installMaven: true
      installGradle: true
  - go:latest

Behavior

• Idempotent by language name. add-language acme java is a no-op when a java entry is already present, whatever its version.
• No confirmation prompt. The edit is written straight to the yml as soon as you run the command.
• Edits the yml only. Run monoceros apply to install the toolchain.
