history

Project history and usage

gat is a Go implementation of a modern `cat`-style terminal file viewer. It keeps the familiar single-command file display model while adding syntax highlighting, Markdown rendering, image display for Sixel-capable terminals, pretty printing, and secret masking.

Project history

The project started publicly in March 2023 and released v0.1.0 the same day. Its official README describes it as a cat alternative written in Go and documents a steady release series through the 0.x line.

Adoption history

The README documents installation through the author's Homebrew tap, Homebrew core, `go install`, and GitHub release binaries. That places gat in the same terminal-tool packaging niche as other enhanced `cat` replacements, but with a small Go binary distribution story.

How it is used

Users run `gat` with one or more files and optional flags for language selection, output format, themes, Markdown rendering, nonprinting character display, and secret masking. Environment variables such as `GAT_FORMAT` and `GAT_THEME` can provide defaults for output style.

Why package nerds care

gat is package-nerd-relevant as another entry in the long-running ecosystem of `cat` replacements, but its mix of terminal image support, Markdown rendering, and built-in token masking makes it more than a straight colorizer.

Timeline

2023: Public GitHub repository created.
2023: v0.1.0 released.
2025: v0.20.x releases continued the 0.x series.

Related projects

gat relates to traditional Unix `cat`; the official sources describe it generically as a cat alternative rather than positioning it against a specific competing package.
