# Live visual verification of omp TUI config
|
|
|
|
## When
|
|
Changing `~/.omp/agent/config.yml` (statusLine.*, composer.*, theme) on a Frank workstation and needing PROOF of how it renders — not inference from the bundle. The status-line/composer knobs are file-watched: edits repaint the RUNNING session; no restart.
|
|
|
|
## Loop (per trial)
|
|
1. Read the live config line(s) first; edit with `edit` (never batch trials — one state per screenshot).
|
|
2. Capture: `sleep 2 && niri msg action screenshot-screen --path /tmp/x.png --show-pointer false` — flag is `--path` (`-o` is invalid); the write lands asynchronously, so `sleep 1.5` before touching the file.
|
|
3. Crop+scale with PIL to the bar/composer region (known good crop for blankpad right monitor: `(2267,1240,3440,1440)`, 1.3x LANCZOS), then `read` the PNG absolute path.
|
|
4. For pixel facts (rule colors, meter lengths) don't eyeball alone: scan rows with `Image.load()` counting dominant colors; sample every 2px and lower thresholds before concluding "nothing found".
|
|
5. After the matrix, RESTORE the original values and re-screenshot the baseline.
|
|
|
|
## Pitfalls
|
|
- Read a downscaled FULL-screen shot first: Frank's screens carry multiple terminals + a browser; a fixed crop can silently capture a different window's bars (happened during the contextLine audit — two omp windows on one screen).
|
|
- Session-accent rules/borders share colors with meters; color presence alone proves nothing. Compare states against each other, and settle ambiguous pixels from the bundle code path (grep `dist/cli.js` for the render function).
|
|
- Live config drifts (other sessions own files there): never `git add -A` the main checkout to promote a trial; commit from a separate `git worktree add` off the target ref.
|
|
- `read` the absolute `/tmp/...` path for screenshots.
|
|
- Multi-value enums: one screenshot per value; identical renders (e.g. claude shape `contextLine: off` vs `embedded`) are themselves a finding — record them as such.
