From 70403c2bd38ea6280d2fcf7309ccbf3b9d69ec72 Mon Sep 17 00:00:00 2001 From: Terence Date: Wed, 8 Apr 2026 04:17:49 +0800 Subject: [PATCH 01/10] feat(languages): add Rust, C++, and Go source languages across all 452 algorithms Expand language support from 3 (TypeScript, Python, Java) to 6 by adding Rust, C++, and Go source files with synchronized @step markers for all 452 algorithms. Includes per-algorithm correctness tests for all 5 non-TypeScript languages and shell-based test runner infrastructure. - Update SupportedLanguage union type, LANGUAGE_LABELS, MONACO_LANGUAGE_MAP, LANGUAGE_EXTENSIONS, and buildLineMapFromSources for 6 languages - Add 1,356 new source files (452 x 3 languages) with matching @step markers - Add 2,260 per-algorithm test files (452 x 5 languages: Python, Java, Rust, C++, Go) - Add 5 shell test runner scripts and npm test:* commands - Add source-loader.test.ts with 36 Vitest tests - Update all documentation, rules, and agent configs for 6-language support - Fix tracker and storybook test fixtures for expanded SupportedLanguage type --- .claude/PLAN.md | 2 +- .claude/agents/qa-tester.md | 2 +-

multi-language CI, and restructure test files - Add Dockerfile.test with all 6 toolchains (Node 22, Python 3.12, Java 21, Rust, g++, Go) - Add docker-compose.test.yml with per-language test services - Add docker:test:* npm scripts for zero-install test execution - Add sharded CI jobs for Python, Java, Rust, C++, Go in ci.yml and deploy.yml - Optimize CI shards per language (Python 2, Java 4, Rust 8, C++ 4, Go 4) - Move 2,260 language test files from sources/ to algorithm directories - Update test imports: Python sys.path, C++ #include, Rust include!, Java javac -d, Go source copy - Fix 8 C++ portability issues (missing includes for GCC on Linux) - Fix 52 source files with stray export keywords - Fix contains-duplicate and contains-duplicate-ii imports to use ?fn plugin - Update test scripts with --shard and --workers support - Update README, docs/testing.md, docs/deployment.md, docs/contributing.md --- .claude/settings.json | 69 +++++++- .github/workflows/ci.yml | 166

reorganize trackers and visualizers into category subdirectories - Move 36 tracker files from flat src/trackers/ into 11 category subdirs (arrays, dynamic-programming, graph, hash-maps, heaps, linked-lists, matrices, sets, stacks-queues, strings, trees) - Move 32 visualizer files from flat src/components/visualization/ into matching category subdirs - Update barrel src/trackers/index.ts with grouped re-exports - Update VisualizationPanel.tsx imports to new subdir paths - Update 452 pipeline story imports to new visualizer paths - Fix 21 direct bst-operation-tracker imports to use barrel - Add 5 new story files: PalindromeVisualizer, TransformVisualizer, DistanceVisualizer, FrequencyVisualizer, TrieVisualizer - base-tracker.ts and VisualizationPanel.tsx stay at their roots - Zero step-generator changes (barrel absorbs restructuring) --- .../SingleNumberPipeline.stories.tsx | 2 +- .../FloydCycleDetectionPipeline.stories.tsx | 2 +- .../CyclicSortPipeline.stories.tsx | 2 +-

refactor(structure): move test files into __tests__/ and update all documentation - Move 3,616 files (7 test files + 1 story per algorithm) into __tests__/ subdirs - Update all relative imports: TS (../sources/, ../step-generator), Python (sys.path ../ sources), C++ (#include ../sources/), Rust (include! ../sources/) - Update Java/Go test scripts for ../sources/ compilation paths - Add rendered SVG architecture diagrams (architecture-overview, data-flow, state-management) replacing Mermaid code blocks - Update docs/architecture.md with high-level code architecture diagram, algorithm directory layout, project structure tree - Update docs/testing.md with __tests__/ paths, story count 488, test locations - Update docs/contributing.md with new directory structure and story paths - Update docs/deployment.md CI job table with per-language shard counts - Update .claude/CLAUDE.md, rules/architecture.md, rules/testing.md, rules/storybook.md for new file organization ---

and regenerate GIF - Expand demo to 5 scenes showcasing diverse visualizers: Bubble Sort (array bars), step-by-step control, Dijkstra (grid wavefront), BST In-Order (tree), BFS (graph) - Add playFor() helper to reduce scene boilerplate - Fix step-forward crash by resetting before stepping - Output: 640px wide, 12fps, 4.45MB GIF (under 5MB target) --- docs/assets/demo.gif | Bin 4954639 -> 4665665
