"""scripts/setup.py
|
|
|
|
Unified project setup helper (Python-only).
|
|
|
|
This script installs Python dependencies from `requirements.txt` and then
|
|
downloads Playwright browser binaries by running `python -m playwright install`.
|
|
By default this script installs **Chromium** only to conserve space; pass
|
|
`--browsers all` to install all supported engines (chromium, firefox, webkit).
|
|
|
|
Usage:
|
|
python ./scripts/setup.py # install deps and playwright browsers
|
|
python ./scripts/setup.py --skip-deps
|
|
python ./scripts/setup.py --playwright-only
|
|
|
|
Optional flags:
|
|
--skip-deps Skip `pip install -r requirements.txt` step
|
|
--no-playwright Skip running `python -m playwright install` (still installs deps)
|
|
--playwright-only Install only Playwright browsers (installs playwright package if missing)
|
|
--browsers Comma-separated list of Playwright browsers to install (default: chromium)
|
|
--install-editable Install the project in editable mode (pip install -e .) for running tests
|
|
--install-deno Install the Deno runtime using the official installer
|
|
--deno-version Pin a specific Deno version to install (e.g., v1.34.3)
|
|
--upgrade-pip Upgrade pip, setuptools, and wheel before installing deps
