| description | Create reproducible TUI screenshots and GIF demos for documentation with Betamax. Use when asked to capture terminal screenshots, record demos, or author .keys files. |
Use README.md for the authoritative syntax, options, and keys file format. Keep outputs reproducible and deterministic.
Launch any command in a tmux session with a hotkey bound to capture PNG screenshots on demand.
betamax capture <command> # capture with default settings
betamax capture nvim myfile.py # capture inside neovim
betamax capture --preset docs htop # use a named preset
betamax capture --theme dracula --shadow --window-bar colorful htop
Options:
--key KEY — capture hotkey in tmux format (default: C-g / Ctrl+G)--output-dir DIR — output directory (default: ./captures)--cols N / --rows N — terminal dimensions (default: current terminal)--preset NAME — load preset from ~/.config/betamax/presets/<name>.conf--save-text — also save raw ANSI text alongside PNG--window-bar STYLE — add window bar: colorful, colorful_right, rings--border-radius N, --margin N, --padding N — decoration geometry--shadow — enable drop shadow--theme NAME — color theme (dracula, nord, catppuccin-mocha, etc.)Config files (key=value, # comments):
.betamaxrc — project config (searched up to git root)~/.config/betamax/config — global config~/.config/betamax/presets/<name>.conf — named presets.keys file with @set:cols, @set:rows, and @set:output for consistent sizing.@require:termshot for PNG or @require:termshot + ffmpeg for GIFs.@wait/@sleep to reach the desired UI state before capture.betamax "<command>" -f path/to/file.keys.The same decoration flags from betamax capture work on the main command:
betamax myapp -f demo.keys --theme dracula --shadow --window-bar colorful
betamax myapp -f demo.keys --border-radius 10 --padding 10 --margin 20
CLI flags override @set: directives in the keys file, which override .betamaxrc config.
Precedence: CLI > @set: > .betamaxrc > global config > preset > defaults.
