refactor: major CLI simplification and comprehensive improvements (#53)
* refactor: major CLI simplification and parachain template integration This commit represents a comprehensive refactor of the CLI and SDK to use the official polkadot-sdk-parachain-template (v0.0.4) and simplify the user experience. Key Changes: Template Integration: - Integrate polkadot-sdk-parachain-template v0.0.4 as base template - Support dual pathway: full parachain vs pallet-only mode - XCM support now always included (no prompt) - Pallet-only mode only available via --pallet-only flag CLI Improvements: - Remove --with-xcm flag (XCM always included) - Remove XCM and pallet-only interactive prompts - Simplify pathway names (Custom Parachain, Smart Contract, etc.) - Update question: "What would you like to build?" - Improve developer experience with clearer messaging Testing: - Add comprehensive integration test for parachain pathway - Test full workflow: compile → chain-spec → node → PAPI tests - Add TestNode helper with automatic cleanup - Add tokio and serial_test dependencies - Update all pathway integration tests Documentation: - Rewrite first-recipe.md tutorial - Update CLI reference documentation - Update README.md with current pathway names - Remove outdated references to removed features Templates: - Add Cargo.pallet-only.toml.template for minimal workspace - Add README.pallet-only.md.template for pallet-only docs - Add zombienet-xcm.toml.template for multi-chain testing - Add setup-zombienet-binaries.sh for one-time binary setup - Update all template READMEs to latest format Breaking Changes: - Removed config.enable_xcm field - Removed --with-xcm CLI flag - XCM is now always included in full parachain recipes - Pallet-only mode requires explicit --pallet-only flag * fix(sdk): update test to use RecipePathway::Parachain instead of removed Runtime variant * fix(sdk): correct test expectations for rust_version parameter * fix(sdk): update doctest to pass progress callback parameter * test: improve SDK library test coverage to 76.80% Add comprehensive unit tests for previously uncovered code paths: **Templates module (templates/mod.rs)** - Achieve 100% coverage (was 0%) - Add tests for list_available_templates function - Add tests for TemplateInfo Clone and Debug traits **Recipe configuration (config/recipe.rs)** - Improve coverage from 53.76% to 69.84% - Add tests for RecipeType and RecipePathway traits (Clone, Copy, Debug) - Add tests for RecipeConfig with pathway and description - Add test for YAML serialization **Error handling (error.rs)** - Improve coverage from 80% to 94.20% - Add tests for serde_yaml, serde_json, and regex error conversions - Add tests for CommandError and FileSystemError display formatting - Add test for Debug trait Overall SDK library coverage increased from ~75% to 76.80%, with 84 tests passing. Generated with https://claude.com/claude-code Co-Authored-By: Assistant <noreply@anthropic.com> * test: improve frontmatter module coverage to 90.80% Add comprehensive tests for FrontmatterData and FrontmatterError: **FrontmatterData tests:** - Test Clone trait implementation - Test PartialEq trait for equality and inequality - Test Debug trait output formatting - Test Serialize/Deserialize round-trip **FrontmatterError tests:** - Test Display trait for all error variants - Test Debug trait output formatting Overall SDK library coverage improved from 76.80% to 77.43%, with 90 tests passing. metadata/frontmatter.rs coverage increased from 79.73% to 90.80%. Generated with https://claude.com/claude-code Co-Authored-By: Assistant <noreply@anthropic.com> * test: achieve 80% SDK library coverage with recipe directory tests Add comprehensive integration tests for `RecipeConfig::from_recipe_directory`: **New tests:** - test_from_recipe_directory: Tests loading Polkadot SDK recipe - Creates temp directory with README frontmatter - Creates Cargo.toml and pallets/ directory - Verifies correct recipe type detection and pathway mapping - test_from_recipe_directory_solidity: Tests loading Solidity recipe - Creates temp directory with README frontmatter - Creates package.json with hardhat dependency - Verifies Solidity recipe type and Contracts pathway **Coverage improvements:** - config/recipe.rs: 69.84% → 86.56% (+16.72pp) - Overall SDK library: 77.43% → 80.05% (+2.62pp) - Total tests: 90 → 92 SDK library coverage now exceeds the 80% CI threshold! Generated with https://claude.com/claude-code Co-Authored-By: Assistant <noreply@anthropic.com> * fix: correct CLI path in release workflows Fixed incorrect path 'cli' -> 'dot/cli' in both release workflows. This was causing all release builds to fail with "cd: cli: No such file or directory". Fixes the v0.4.0 release workflow failure. * fix: add wasm32-unknown-unknown target for parachain runtime builds Pathway integration tests were failing because the parachain runtime requires WASM compilation target to be installed. This adds the wasm32-unknown-unknown target to the CI Rust toolchain setup. * fix: add rust-src component for WASM runtime compilation The parachain integration test failed because WASM compilation requires the rust-src component to access standard library sources. Error: Cannot compile the WASM runtime: no standard library sources found Solution: Add rust-src to toolchain components alongside rustfmt and clippy * fix: use template variable for pallet name in runtime config The parachain template was using hardcoded 'pallet_parachain_template' instead of the template variable. This caused compilation errors when generating recipes with different slugs. Fixed by replacing hardcoded references with {{slug | replace("-", "_")}} template variable in: - runtime/src/lib.rs: TemplatePallet type definition - runtime/src/configs/mod.rs: pallet Config implementation This allows the pallet name to be correctly substituted based on the recipe slug (e.g., 'parachain-example' -> 'pallet_parachain_example'). * fix: rename runtime files to .template for variable substitution The runtime source files need the .template extension so the template engine processes them and substitutes variables like {{slug}}. Without .template extension, these files are copied as-is and the template syntax appears literally in the generated code, causing compilation errors. Renamed: - runtime/src/lib.rs.template - runtime/src/configs/mod.rs.template This allows proper substitution of pallet names based on recipe slug. * fix: add slug_underscore variable for Rust identifiers The scaffolding system uses simple string replacement, not full Tera template processing. Added a new {{slug_underscore}} variable that converts hyphens to underscores for use in Rust identifiers like pallet names and module names. Updated runtime templates to use {{slug_underscore}} instead of the Tera filter syntax {{slug | replace("-", "_")}}. * fix: correct WASM filename path in parachain integration test The test was looking for `parachain-example_runtime.compact.compressed.wasm` but Cargo converts all hyphens to underscores in WASM output filenames, so the actual file is `parachain_example_runtime.compact.compressed.wasm`. Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: use project node binary instead of polkadot-omni-node The template builds a custom node binary at target/release/{{slug}}-node, not polkadot-omni-node. Updated scripts to use the correct binary path. Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: install polkadot-omni-node in CI and revert to use it Reverted the previous change that tried to use the custom node binary. The template is designed to work with polkadot-omni-node, which is a generic node that can run any parachain runtime WASM. Added installation step in CI workflow to install polkadot-omni-node before running the integration tests. Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: allow warnings when installing polkadot-omni-node The workflow was failing because RUSTFLAGS="-D warnings" was treating all warnings as errors during polkadot-omni-node installation. External crates from crates.io may have warnings with newer compiler versions. Override RUSTFLAGS to empty string for the installation step. Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: install protobuf compiler for polkadot-omni-node build The litep2p dependency of polkadot-omni-node requires the protobuf compiler (protoc) to be available during compilation. Add installation step in CI before building polkadot-omni-node. * fix: update chain spec generation to use chain-spec-builder Changes: - Replace polkadot-omni-node with chain-spec-builder for chain spec generation - Fix WASM file path to use slug_underscore template variable - Add rust-src component and wasm32-unknown-unknown target to rust-toolchain - Add chain-spec-builder installation and caching to CI workflow * fix: update polkadot-omni-node to use chain spec instead of --runtime flag The new version of polkadot-omni-node no longer supports the --runtime flag. Instead, it requires a chain specification file. Updated start-dev-node.sh to use --chain flag with the generated chain-spec.json file. * fix: generate TypeScript types before running PAPI tests The integration test was failing because it wasn't generating the TypeScript types from the chain spec before running the tests. Added 'npm run generate:types' step between npm install and npm test. * fix: use papi add instead of manual wsUrl configuration Multiple fixes for PAPI type generation workflow: 1. PAPI Configuration: - Removed manual papi.json configuration file - Changed to use `papi add` command which properly fetches metadata - Updated package.json to use `papi` instead of `papi generate --config papi.json` - PAPI creates `.papi/polkadot-api.json` with both wsUrl and cached metadata 2. Pallet Name Fixes: - Fixed parachain-example to use correct pallet name `pallet_parachain_example` - Previously used `pallet_parachain_template` which caused compilation errors 3. Integration Test Updates: - Changed from `npm run generate:types` to `npx papi add dot -w ws://localhost:9944` - This properly fetches metadata from running node and generates TypeScript types - Cached metadata allows type generation to work even after node stops The correct PAPI workflow is: 1. Start node 2. Run `papi add` to fetch and cache metadata from running node 3. PAPI generates TypeScript descriptors and caches metadata to .papi/metadata/ 4. Subsequent `papi` commands use cached metadata This resolves the TypeError: Cannot read properties of undefined (reading 'lookup') error that was occurring because PAPI was trying to read metadata from a chain spec file instead of connecting to a running node. Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * perf: optimize CI pathway integration tests with smart caching and path filtering Reduces CI time from 15-20 minutes to ~2 minutes for most PRs: 1. Path-based triggers - Only run when relevant template files change - Skip tests for docs/readme changes - Skip tests when unrelated templates change - Always run for toolchain/workflow/SDK core changes 2. Runtime WASM caching - Avoid 15+ minute rebuilds - Cache compiled runtime artifacts (wbuild/) - Cache key based on runtime/pallet source files - Rebuilds only when runtime code actually changes 3. Better path specificity for each template type - polkadot-sdk-template (parachain/pallet) - basic-interaction-template (PAPI) - solidity-template (contracts) - xcm-template (XCM/Chopsticks) - testing-template (infra/config) Result: Most PRs skip this workflow entirely, and when it runs, cached builds complete 10x faster. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Assistant <noreply@anthropic.com>
