From 0379613e41bf4ee4a65ed06240f83069a1f5bcf5 Mon Sep 17 00:00:00 2001 From: adriens Date: Sat, 31 Jan 2026 14:17:36 +1100 Subject: [PATCH 1/7] feat: Add CUE validation for extension description.yml files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements comprehensive schema validation for all 153 extension description.yml files using CUE (https://cuelang.org/). This ensures consistency, catches errors early, and maintains quality across all community extension definitions. Changes: - Add CUE schema definition (schema/description.cue) * Validates required fields (name, description, language, build, etc.) * Type checking for strings, numbers, and lists * Format validation for GitHub repos and git references * Supports all existing field variations and edge cases - Add validation script (scripts/validate_descriptions.sh) * Validates all description.yml files in batch * Color-coded output with clear error messages * Summary statistics and failed file reporting - Add GitHub Actions workflow (.github/workflows/validate_descriptions.yml) * Automatic validation on PRs and pushes * Triggers on changes to description.yml, schema, or validation script * Installs CUE and runs validation as status check - Add comprehensive documentation * schema/README.md: Complete validation guide with examples * VALIDATION.md: Quick contributor reference Validation Results: ✅ All 153 description.yml files pass validation ✅ Schema accommodates all existing variations ✅ Fast execution (~2 seconds for all files) Benefits: - Prevents invalid description.yml files from being merged - Provides immediate feedback to contributors - Enforces consistent structure across all extensions - Self-documenting schema with inline comments - Easy to extend for future requirements Usage: Local: ./scripts/validate_descriptions.sh CI: Runs automatically on PRs Closes # --- .github/workflows/validate_descriptions.yml | 47 +++++ VALIDATION.md | 50 ++++++ schema/README.md | 185 ++++++++++++++++++++ schema/description.cue | 70 ++++++++ scripts/validate_descriptions.sh | 71 ++++++++ 5 files changed, 423 insertions(+) create mode 100644 .github/workflows/validate_descriptions.yml create mode 100644 VALIDATION.md create mode 100644 schema/README.md create mode 100644 schema/description.cue create mode 100755 scripts/validate_descriptions.sh diff --git a/.github/workflows/validate_descriptions.yml b/.github/workflows/validate_descriptions.yml new file mode 100644 index 000000000..dfbe2773e --- /dev/null +++ b/.github/workflows/validate_descriptions.yml @@ -0,0 +1,47 @@ +name: Validate Extension Descriptions + +on: + pull_request: + paths: + - 'extensions/*/description.yml' + - 'schema/description.cue' + - 'scripts/validate_descriptions.sh' + - '.github/workflows/validate_descriptions.yml' + push: + branches: + - main + paths: + - 'extensions/*/description.yml' + - 'schema/description.cue' + - 'scripts/validate_descriptions.sh' + - '.github/workflows/validate_descriptions.yml' + workflow_dispatch: + +jobs: + validate: + name: Validate description.yml files + runs-on: ubuntu-latest + + steps: + - name: Checkout repository + uses: actions/checkout@v4 + + - name: Install CUE + run: | + curl -fsSL https://cuelang.org/install.sh | sh + echo "$HOME/.local/bin" >> $GITHUB_PATH + + - name: Verify CUE installation + run: cue version + + - name: Validate description.yml files + run: | + chmod +x scripts/validate_descriptions.sh + ./scripts/validate_descriptions.sh + + - name: Summary + if: success() + run: | + echo "✅ All description.yml files validated successfully!" >> $GITHUB_STEP_SUMMARY + echo "" >> $GITHUB_STEP_SUMMARY + echo "**Total files validated:** $(find extensions -name 'description.yml' | wc -l)" >> $GITHUB_STEP_SUMMARY diff --git a/VALIDATION.md b/VALIDATION.md new file mode 100644 index 000000000..4d520502d --- /dev/null +++ b/VALIDATION.md @@ -0,0 +1,50 @@ +# Contributing Extension Validation Guide + +When adding or modifying a DuckDB community extension, your `description.yml` file must pass validation. + +## Quick Start + +Before submitting a PR: + +```bash +# Install CUE (one-time setup) +# macOS: +brew install cue + +# Linux: +curl -fsSL https://cuelang.org/install.sh | sh + +# Validate your changes +./scripts/validate_descriptions.sh +``` + +## What Gets Validated? + +All `extensions/*/description.yml` files are checked for: +- Required fields (name, description, language, build, maintainers) +- Correct data types and formats +- Valid GitHub repository references +- Proper structure and syntax + +## Common Issues + +| Error | Solution | +|-------|----------| +| Missing required field | Add the field (e.g., `license: MIT`) | +| Invalid GitHub format | Use `owner/repo` format in `repo.github` | +| Wrong build system | Use `cmake`, `CMake`, or `cargo` | +| Invalid version type | Quote string versions: `version: "1.0.0"` | + +## Full Documentation + +See [schema/README.md](schema/README.md) for: +- Complete schema reference +- Field-by-field documentation +- Example files +- Troubleshooting guide + +## CI Validation + +Your PR will automatically run validation.
