YAS demo text

make demo/img writes ANSI-coloured statusline snapshots to demo/<scenario>.txt (and per-theme renders under demo/themes/). This skill strips the ANSI escape sequences so the box-drawing layout survives as plain, diff-able, paste-able text.

Quick start

Render the snapshots, then strip them into demo/text/ (mirrors the demo/ tree):

make demo/img                                   # or: DEMO_ONLY=tasks make demo/img
.claude/skills/yas-demo-text/scripts/demo-text.sh

demo/text/<scenario>.txt now holds the colour-free render. Both demo/ and demo/text/ are gitignored, so these are scratch artifacts — diff them, paste them, regenerate them; don't commit them.

Strip arbitrary output

scripts/strip-ansi.sh is a plain ANSI filter (stdin or named files → stdout), wrapping sed 's/\x1B\[[0-9;]\{1,\}[A-Za-z]//g':

COLUMNS=160 uv run python claude/statusline_command.py < ops/session-info-example.json \
  | .claude/skills/yas-demo-text/scripts/strip-ansi.sh

Before/after comparison

make demo/img && .claude/skills/yas-demo-text/scripts/demo-text.sh
cp -r demo/text /tmp/yas-before        # stash the baseline
# ... make your renderer change ...
make demo/img && .claude/skills/yas-demo-text/scripts/demo-text.sh
diff -ru /tmp/yas-before demo/text     # see exactly which cells moved

Notes

• The strip regex matches CSI sequences (\x1B[…<letter>), removing colour, bold and italic; it leaves box-drawing and Nerd Font glyphs intact, so column alignment is preserved exactly.
• Nerd Font PUA glyphs render as boxes outside a Nerd-Font terminal (e.g. on GitHub), but the layout and text labels still read clearly. For a snapshot meant to paste into GitHub markdown, render in the github glyph mode first (YAS_GLYPH_MODE=github make demo/img): it folds the box-drawing frame, block/sparkline ramp, and PUA icons to width-1 EAW-narrow/ASCII stand-ins, so the result stays a clean, box-free rectangle in a browser monospace font. The yas-pr skill uses this by default for before/after PR renders.
• The repo's Python strip_ansi (test/helper.py) is SGR-only and for tests; this skill's sed filter is broader and for the demo snapshots.
