From ae96526d4bbb4307aceeecbd5739586497dc2e20 Mon Sep 17 00:00:00 2001 From: yusyus Date: Thu, 1 Jan 2026 23:10:55 +0300 Subject: [PATCH] feat(C2.7): Add standalone codebase-scraper CLI tool MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Created src/skill_seekers/cli/codebase_scraper.py (450 lines) - Standalone tool for analyzing local codebases without GitHub API - Full .gitignore support using pathspec library Features: - Directory tree walking with .gitignore respect - Multi-language code analysis (Python, JavaScript, TypeScript, C++) - Language filtering (--languages Python,JavaScript) - File pattern matching (--file-patterns "*.py,src/**/*.js") - API reference generation (--build-api-reference) - Comment extraction (enabled by default) - Configurable analysis depth (surface/deep/full) - Smart directory exclusion (node_modules, venv, .git, etc.) CLI Usage: skill-seekers-codebase --directory /path/to/repo --output output/codebase/ skill-seekers-codebase --directory . --depth deep --build-api-reference skill-seekers-codebase --directory . --languages Python,JavaScript Output: - code_analysis.json - Complete analysis results - api_reference/*.md - Generated API documentation (optional) Tests: - Created tests/test_codebase_scraper.py with 15 tests - All tests passing ✅ - Test coverage: Language detection (5 tests), directory exclusion (4 tests), directory walking (4 tests), .gitignore loading (2 tests) Dependencies Added: - pathspec>=0.12.1 - For .gitignore parsing Entry Point: - Added skill-seekers-codebase to pyproject.toml Related Issues: - Closes #69 (C2.7 Create codebase_scraper.py CLI tool) - Part of C2 Local Codebase Scraping roadmap (TIER 3) Files Modified: - src/skill_seekers/cli/codebase_scraper.py (CREATE - 450 lines) - tests/test_codebase_scraper.py (CREATE - 160 lines) - pyproject.toml (+2 lines - pathspec dependency + entry point) --- pyproject.toml
