OSRF Project Advances colcon-mixin for Robotics Software Builds
TL;DR. A Google Summer of Code project improved colcon-mixin, a robotics build tool, by adding support for mixin composition. - The update allows mixins to reference each other, simplifying complex build configurations for developers. - This change addresses a longstanding request for modularity in colcon-mixin arguments. - It also introduces a behavior change in how multiple mixins merge scalar arguments.
- Google Summer of Code (GSoC) project enhanced colcon-mixin.
- Mixin composition feature added, allowing mixins to include other mixins.
- Addresses previous limitation where mixins were standalone bundles.
- Introduces new merging logic for scalar arguments in colcon-mixin.
