Rubric

bat in Go — a cat clone with wings

$ go install goforge.dev/rubric@latest
Source repository pkg.go.dev

Rubric is bat written in Go — a cat(1) clone with wings. It ports sharkdp/bat to Go, aiming for feature parity while tracking current upstream behavior. Syntax highlighting and themes come from chroma (the Go analogue of Rust’s syntect): ~296 languages and ~74 themes out of the box.

Features

  • Syntax highlighting with language auto-detection (name, extension, content)
  • Themes (--theme, --list-themes; bat theme names aliased to chroma styles)
  • Decorations: line numbers, grid, header, rule, snip (--style)
  • Git change markers (--style=changes) and --diff / --diff-context
  • Line ranges (-r) and line highlighting (-H)
  • Wrapping (--wrap, --chop-long-lines), tab expansion, blank-line squeeze
  • Paging through less (auto when interactive), syntax mapping, config file

Run

go install goforge.dev/rubric@latest
rubric src/main.go
rubric --style=full --theme=GitHub README.md
git diff | rubric -l diff

Rubric is built as a goforge workspace.
