Preview terminal color themes with realistic scenarios. Shows shell prompts, build output, git logs, diffs, docker containers, system monitors, and more -- all using ANSI colors 0-15 so your theme controls the appearance.
Useful for testing and designing terminal color schemes. Instead of staring at color swatches, see how your 16 colors actually play together across real-world terminal output.
Recorded under Catppuccin Mocha. Since diorama draws only in ANSI 0-15, the demo looks like whatever theme it runs under.

mise install # rust, task, lefthook, cocogitto, vhs
lefthook install # git hooks
task # list tasks
task lint # rustfmt check + clippy
task test
task build # release binary
CI runs rustfmt, clippy, and the tests on every push, and commit messages and branch names get checked against conventional-commit rules on every PR.
The README GIF is rendered from demo.tape with VHS.
Regenerate it with task demo (needs diorama on PATH plus ttyd and ffmpeg,
which VHS shells out to: brew install ttyd ffmpeg).
