🔧 Pre-commit Hooks
Reusable pre-commit hooks for OpenSCAD projects.
Published on PyPI as kellerlab-pre-commit-hooks.
📌 What
Two hooks for OpenSCAD-based 3D printing projects:
| Hook | Description |
|---|---|
flatten-validate |
Runs scadm flatten --all and fails if flattened files have uncommitted changes |
optimize-images |
Resizes oversized JPEGs/PNGs, compresses them, and strips metadata (privacy) |
🔧 Usage
Add to your .pre-commit-config.yaml:
- repo: https://github.com/kellerlabs/pre-commit-hooks
rev: v0.1.0 # use latest tag
hooks:
- id: flatten-validate
- id: optimize-images
flatten-validate
Flattens OpenSCAD files via scadm and validates that the output is committed. Reads flatten config from scadm.json automatically.
- id: flatten-validate
# Override trigger pattern (default: always_run)
always_run: false
files: '^(scadm\.json|models/.*\.scad)'
Options:
| Arg | Default | Description |
|---|---|---|
--flatten-dir |
Read from scadm.json |
Override flatten output dirs (list of paths/globs) |
optimize-images
Resizes JPEGs and PNGs exceeding max width, compresses them, and strips metadata. EXIF data (including GPS coordinates) is removed from JPEGs; text metadata chunks are removed from PNGs.
- id: optimize-images
args: [--max-width=1920, --quality=85]
Options:
| Arg | Default | Description |
|---|---|---|
--max-width |
1920 |
Maximum image width in pixels |
--quality |
85 |
JPEG compression quality (1-95, ignored for PNG) |
Both hooks fail when files are modified, printing instructions to git add the changes. Re-run git commit after staging.
