Asciinema demo recorder

Regenerates homepage/public/fresh-demo.cast, the recorded Fresh demo played inside the hero on the landing page via homepage/public/vendor/asciinema-player/.

Files

Path	Purpose
`record.py`	Python driver. Forks a pty, runs `fresh`, sends a canned key timeline, writes asciicast v2 to disk.
`setup-demo.sh`	Creates a small Rust project (main.rs, notes.md, Cargo.toml) with a git history and a local uncommitted edit so the git gutter and Review Diff have content to show.
`regenerate.sh`	One-shot: builds fresh if needed, sets up the demo workspace, runs the recorder.

Regenerate the demo

scripts/record-asciinema/regenerate.sh

The cast lands at homepage/public/fresh-demo.cast (~270 KB, ~35 s). Rebuild the site with bun run build to deploy.

Override paths / binary

FRESH=/path/to/fresh \
DEMO_DIR=/tmp/my-demo \
OUTPUT=/tmp/custom.cast \
  scripts/record-asciinema/regenerate.sh

Or call the Python driver directly:

scripts/record-asciinema/setup-demo.sh /tmp/demo
scripts/record-asciinema/record.py /tmp/out.cast \
    --fresh ./target/debug/fresh \
    --demo /tmp/demo

What the demo shows

main.rs open with Rust syntax highlighting and a dirty git marker.
The command palette (Ctrl+P) and its command catalogue.
Select Theme with live-preview theme cycling.
Fuzzy file finder opening notes.md, then buffer switcher back.
Multi-cursor (Ctrl+D ×3) on the word pub.
Live Grep (Find in Files) with its split preview panel.
Magit-style Review Diff with hunk navigation and s to stage.

Editing the timeline

The sequence lives in record.py under the TIMELINE = [] block. Each tuple is (delay_before_event_seconds, bytes_to_send). An empty payload is a pure pause.

Before adding a new step, drive it manually in tmux to make sure the command name, key binding and visible effect match your expectation:

tmux new-session -d -s f -x 110 -y 30 \
    "cd /tmp/fresh-demo-workspace && ./target/debug/fresh main.rs"
tmux send-keys -t f C-p
tmux capture-pane -t f -p       # read the visible pane

When the cast doesn't match what you meant, it's almost always one of:

the palette defaults to >command mode — use Backspace to fall into file-finder mode,
Review Diff is a real command but review diff / quit might not match what you expect — verify with the palette first,
multi-cursor needs a prior selection: Ctrl+Shift+Right selects the word, then Ctrl+D extends to the next match.
