## プロジェクトの歴史と使われ方

nyan is a Go command-line replacement for the narrow use case of running cat on source files while keeping terminal syntax highlighting. Its upstream README describes it as a colorizing cat command, with language selection, line numbers, and selectable themes such as monokai, dracula, pygments, and solarized variants.

### プロジェクトの歴史

The GitHub repository was created on 2019-07-08 by toshimaru. The README explicitly ties the name to Nyan Cat, but the tool's implementation niche is practical rather than novelty: plain file output with optional syntax coloring instead of a pager-first workflow.

### 採用の歴史

nyan started as a small Homebrew-tap style developer utility and the README notes that version 1.2.0 was merged into homebrew-core. The Homebrew formula API reported stable version 1.2.6 and 610 installs over the 365-day analytics window queried on 2026-07-01, which fits a modest but real CLI-tool audience.

### 使われ方

Package nerds use nyan where bat is more UI than they want: quick terminal inspection of files with colors, sometimes with --language to force highlighting, --theme to match a terminal theme, --number for line numbers, and --list-themes to preview palettes.

### パッケージ好きにとっての重要性

nyan sits in the tiny ecosystem of colorizing cat clones such as ccat and bat. Its significance is mostly packaging shape: a small Go single-command utility that graduated into homebrew-core because it cleanly solves one terminal habit.

### タイムライン

- 2019-07-08: GitHub repository created.
- v1.2.0: upstream README says nyan was merged into homebrew-core.
- 2026-07-01: Homebrew formula API reported stable version 1.2.6.
