CLI and art videos

The guided tour of the rich command, then the CLI and art videos of earlier releases, kept as a record. Every other recording, the terminal apps and the raycaster among them, is on Terminal recordings.

Run the suite in your terminal

CLI 0.0.8 introduced rich --demo: a single guided pass through the suite with three-second section pauses. Use --demo-delay 5 to slow it down; Ctrl+C stops cleanly. See the tour instructions.

The guided tour of the rich CLI suite, recorded in a real terminal

Cast · GIF · Tape

For terminal apps built on intuiTUIve, see Eleven apps, rebuilt: recordings of the file manager, git client, system monitor, HTTP client, game, CSV viewer, disk treemap, music player and task list, rebuilt from real terminal apps.

This recording runs rich --demo --demo-delay 1.5 in a real terminal, faster than the default three-second pace. It is a tape recorded by rich record, so it is replayed from the build in this repository and CI checks its screenshots on every change:

Console log Recorded exports
console.log and progress.log lines, each with its time and caller, above a finished progress bar A recording console's text, HTML and SVG exports
Inspect Diff Mermaid Filter and highlight
Structured data as a tree A text diff A Mermaid flowchart as text Filtered and highlighted log lines
Ask in a script FIGlet banner Image diff Tour complete
A rich choose picker, with the answer captured by the shell A FIGlet banner An image diff The end of the tour

The recordings below, up to 0.0.12, are kept as historical records. They were captured by Python scripts that rich record has since replaced; their raw recordings and source/binary provenance are in .github/evidence/.

The 0.0.12 tour: MP4 · GIF. It shows rich mermaid drawing a flowchart as text, code themes in the terminal's own palette, --filter and --highlight, and --image-fit native.

The 0.0.11 tour is kept as a historical recording: MP4 · GIF. It shows inspect, diff, view, the hex, unicode and ansi explain inspectors, a theme file, a redacted capture, Atkinson dithering with OKLab colour distance, and transparent images.

The 0.0.10 tour is kept as a historical recording: MP4 · GIF. It shows a pushed theme, ~~~ strikethrough, Progress with speed and time remaining, a two-file watch, and quadrant, ANSI16 and tone adjustments.

CLI 0.0.9 workflows

The optimized 0.0.9 preparation build demonstrates ANSI256 image rendering with and without Floyd–Steinberg dithering, a named theme, read-only doctor diagnostics, available demo sections and terminal batch progress. Each scene uses actual recorded terminal output, with captions and three-second holds; no audio.

The raw recordings, fixture, export checks and source/binary hashes are committed in .github/evidence/0.0.9/. See release notes for the bounded feature scope and recipes for copyable commands.

CLI 0.0.8 workflows

These clips replay actual output captured from an optimized rich (rs-rich-cli) 0.0.8 binary in an 88 × 28 PTY. Command captions are added, each completed result is held for two seconds, and there is no audio.

All nine crop anchors

A deterministic asymmetric source makes the crop position visible. Every anchor is recorded in a wide and a tall viewport: cover preserves the source aspect ratio, so a particular viewport crops only one axis. Positions on the other axis therefore produce the same crop.

Plan a batch, then export in parallel

The first command uses --dry-run; the capture script checks that the destination is still empty. The second exports both documents with --jobs 2, checks the resulting HTML files, and records the real JSON completion report.

Inspect configuration and overrides

config validate, default settings, the preview profile, and explicit CLI width/color/pager overrides are shown in sequence. The fixture deliberately places the profile before defaults to demonstrate that TOML document order does not change precedence.

Capture evidence and benchmark results include source/binary hashes, exact arguments, exit codes, raw ANSI/asciinema recordings, fixtures and exported HTML. The videos were made by scripts/capture_v8_demos.py, since replaced by rich record (see it at commit 9157264). The benchmark still runs from the repository root:

cargo build --release -p rs-rich-cli --locked
python scripts/bench_batch.py

The benchmark compares jobs 1, 2 and 4 using generated JSON inputs and fresh HTML destinations. It checks that all exports are byte-identical across job counts. Timings include process startup and disk writes; results depend on host, input size and filesystem caches, and do not promise a parallel speedup. PTY capture requires POSIX, FFmpeg and DejaVu fonts; the benchmark uses Python's standard library only.

CLI 0.0.7 demos

These clips were captured from the built rich (rs-rich-cli) 0.0.7 binary (target/release/rich, default features). They replay its actual PTY output; captions are added, still results are held for two seconds, and watch output retains event timing sampled at 10 fps. There is no audio.

Image render modes

Watch and batch workflows

A file changes, becomes invalid and recovers; batch then exports two HTML files.

Commands and source/binary hashes are committed with raw ANSI/asciinema recordings and the exported HTML files. The alpha fixture was generated deterministically by the capture script, scripts/capture_release_demos.py, since replaced by rich record (see it at commit 9157264). See workflow recipes and image fitting options.

Archived GIF playback

The same bouncing-ball GIF rendered with truecolor half-blocks and colored ASCII. These clips replay real output from our archived CLI recordings. They have no audio.

The left side uses upper-half block characters to represent two vertical pixels per terminal cell. The right side uses ASCII characters; both retain color.

Half-block rendering

From a repository checkout, in a truecolor terminal:

cargo run -p rs-rich-cli -- --gif crates/rich-art/examples/assets/ball.gif --gif-mode blocks --width 32 --loop 1

ASCII rendering

Download ASCII MP4

cargo run -p rs-rich-cli -- --gif crates/rich-art/examples/assets/ball.gif --gif-mode ascii --width 32 --loop 1

Animation needs an interactive terminal. Redirected output renders one frame; color support depends on terminal capabilities. See the CLI guide.

How these videos were made

The source is the project's v0.0.4 PTY evidence, captured in an 80 × 24 terminal with a 32-column image. These are replays of that recorded output, not fresh recordings of the current checkout. The generator verifies the saved ANSI SHA-256 hashes and checks that the asciinema output matches the ANSI stream.

The replay keeps complete frames, crops unused terminal space, uses DejaVu Sans Mono, and displays each frame for 100 ms. MP4s repeat the sequence three times; the preview GIF loops continuously. This presentation timing differs from the original recording. Titles and comparison layout are added by the media script.

The progress and spinner GIFs elsewhere in the docs are conversions of committed SVG frame sequences exported by the library. They are not terminal recordings.
