# colcon-output — Extension for colcon to customize the output in various ways.

License: permissive · Maintenance: active · Downloads: 183.7K/mo

## What it is and what it does

colcon-output is a plugin for the colcon build system that extends colcon-core's capabilities to customize how build output is displayed and formatted. It sits in the colcon ecosystem as an optional output handler, allowing developers to tailor the presentation of build logs and status messages during the build process.

The package is designed for developers using colcon who need finer control over build output. It requires only colcon-core as a runtime dependency and supports Python 3.6 and later across macOS, Windows, and POSIX systems.

Use it for:

- Customize build output when using colcon for multi-package builds
- Integrate colcon into CI/CD pipelines with tailored output for log parsing
- Reduce visual noise in build logs by reformatting colcon's default output
- Enhance readability of build status for teams working with large colcon workspaces
