history

Project history and usage

Clog is a small command-line filter for colorizing log streams, commonly used with tools such as tail -f so important log lines stand out in a terminal.

Project history

The project is maintained under the Gothenburg Bit Factory organization, with official documentation hosted on gothenburgbitfactory.org and source code in the GothenburgBitFactory/clog GitHub repository.

Adoption history

Package-manager adoption is modest but broad for a niche log utility: the input records Homebrew, Debian, Ubuntu, and MacPorts package names, which fits a Unix-terminal workflow.

How it is used

Users pipe a log stream into clog with a section name; rules in ~/.clogrc match patterns and apply color, match-only coloring, suppression, or blank-line output.

Why package nerds care

Clog matters to package nerds as a focused example of the classic Unix filter model: it does one terminal task, keeps configuration in a dotfile, and composes with tail and other shell tools.

Timeline

2022: GitHub releases list Clog 1.3.0 as the latest release.
2025: The official Clog documentation site remained published by Gothenburg Bit Factory.

Related projects

The official site links Clog alongside other Gothenburg Bit Factory projects such as Taskwarrior and Timewarrior.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
