How it got here

2019–2020 · Modular architecture and feature expansion

The project underwent a major architectural refactoring to establish a modular, state-machine-driven codebase, separating concerns like CLI parsing, color handling, and diff processing into distinct modules. This period also introduced a comprehensive feature set for diff styling, navigation, and shell completion, supported by robust integration testing and automated release processes.

2021 · Modularization and utility expansion

This period focused on reorganizing the codebase into dedicated modules for handlers and utilities, significantly improving code maintainability. The team expanded the tool's capabilities by adding new subcommands for themes, colors, and external tools, while also integrating the bat library for enhanced syntax highlighting and pager management.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 95a0e224f5 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
