# memect-ppx

Use the local `ppx` CLI to parse PDFs and images into structured Markdown and JSON.

## Runtime Requirements

- Use Python `>= 3.12`.
- Prefer installing PPX into a virtual environment instead of the system Python.
- If `ppx` is missing, read `references/troubleshooting.md` and create a virtual environment before installing dependencies.
- Keep this skill's frontmatter `version` synchronized from the repository `pyproject.toml` with `scripts/sync_version.py`.

## Workflow

1. Confirm the runtime uses Python `>= 3.12`.
2. Check the runtime with `scripts/check_ppx_env.sh`.
3. If `ppx` is missing, create or use a virtual environment and install PPX there.
4. Choose parsing options:
   - Use `--ocr auto` by default.
   - Use `--ocr yes` for scanned PDFs or screenshots.
   - Use `--ocr no` for native PDFs when OCR causes noise.
   - Use `--table auto` by default.
   - Use `--table llm` only when the user needs highest table accuracy and an LLM backend is configured.
5. Run `ppx parse <input> -o <output>`.
6. Inspect the output folder and report the main artifacts:
   - `doc.md`
   - `doc.json`
   - `pages/`
   - `images/` when figures are extracted
7. If parsing fails, summarize the failing step and load the relevant note from `references/`.

## Common Commands

```bash
ppx parse report.pdf -o output/
ppx parse scan.pdf --ocr yes -o output/
ppx parse figure.png -o output/
ppx parse report.pdf --pages "1-5,10" -o output/
ppx parse report.pdf --table llm --backend deepseek -o output/
```

## Output Contract

- Prefer returning the absolute output directory.
- Mention whether the result came from `doc.md`, `doc.json`, or page-level files.
- Call out OCR mode, table mode, and backend when they materially affect accuracy.

## References

- Read `references/cli-options.md` when choosing parse flags.
- Read `references/backend-config.md` when using DeepSeek, Paddle, or GLM backends.
- Read `references/troubleshooting.md` when PPX is missing, Python is too old, or runtime dependencies fail.
