colcon-bash
Extension for colcon to provide Bash scripts.
Decision gist · record as of 2026-08-14
Yes, if you use colcon and need Bash script generation for environment setup. Install friction is low and the package is actively maintained. However, the Alpha status and two-year gap since the last release suggest it may not be heavily developed; verify that the current version meets your colcon version requirements before depending on it for production workflows.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires colcon-core to be installed; colcon-bash is a plugin that extends colcon and has no standalone utility.
- Low friction install with a single pure-Python wheel dependency on colcon-core.
- Active maintenance with recent commits, though the package is classified as Alpha and last release was over 2 years ago.

What it is and what it does
colcon-bash is a plugin for the colcon build system that generates Bash shell scripts for environment setup and workspace management. It extends colcon-core to produce shell initialization files that developers source to configure their build environment. The package is a pure-Python wheel with a single runtime dependency on colcon-core, making it lightweight to install.
It is used as part of the colcon ecosystem to automate shell environment configuration across different operating systems (macOS and POSIX systems). When integrated into a colcon workflow, it handles the generation of Bash-compatible setup scripts without requiring manual shell configuration. The package has been maintained since 2018 and remains active, though it carries an Alpha development status and has not had a release in over two years.
Use it for
- Generate Bash environment setup scripts automatically when building multi-package colcon workspaces.
- Configure shell environment variables and paths for ROS 2 or other colcon-based projects on macOS and Linux.
- Automate workspace initialization so developers can source a single script to activate all build dependencies.
- Integrate Bash script generation into CI/CD pipelines that use colcon for build orchestration.
