Description

Description

Provide a tool that would translate a YAML launchfile to XML, or vice versa.

I believe this should be mechanically possible without special fuzzy logic.

Because it would go through intermediate representation, I think the real goal is that we could possibly translate from Python->frontend for files that use only frontend-exposed actions. Given how arg specs are done imperatively/dynamically right now, that still might not be easy though.

Motivation

Allow folks to migrate codebases more easily.

Research direction

No files or tests are named. Start by mapping the YAML and XML launchfile representations and the intermediate representation, then determine how the Python frontend and imperative argument specifications fit. Done means a defined, tested translation path in both directions.
