description: Export a diagram-design HTML file to SVG and PNG
|
|
argument-hint: "<html-file> [--svg-only|--png-only] [--scale=N] [--output=<path>]"
|
|
---
|
|
|
|
Export diagram HTML at `$1` to `.svg` or `.png`, following `skills/diagram-design/references/export.md` from installed diagram-design package. Read that reference first; treat it as source of truth.
|
|
|
|
Full argument string: `$ARGUMENTS`
|
|
|
|
## Defaults
|
|
|
|
- Produce both `.svg` and `.png` next to source (for example, `diagram.html` → `diagram.svg` + `diagram.png`).
|
|
- Render PNG at `device_scale_factor=2`.
|
|
|
|
## Flags
|
|
|
|
- `--svg-only` — emit SVG only. Skip Playwright.
|
|
- `--png-only` — emit PNG only.
|
|
- `--scale=1`, `--scale=2`, or `--scale=3` — override PNG device scale factor.
|
|
- `--output=<path>` — override output base path; append format extension.
|
|
|
|
## Required behavior
|
|
|
|
1. No source path → ask user which `.html` file to export. Do not guess.
|
|
2. Source is `assets/index.html` → refuse; ask for specific diagram file.
|
|
3. Source lacks `<svg>` → refuse; write nothing.
|
|
4. PNG requested without Playwright → show install instruction from reference verbatim; stop. Do not auto-install.
|
|
5. `--scale` outside {1, 2, 3} → reject.
|
|
|
|
After export, report output paths plus sizes.
