tom_analyzer_shared 0.2.0

Shared analyzer-summary caching infrastructure reused by Tom code generators (reflection, d4rt bridges, etc).

Changelog

0.2.0

• Added resolveDartSdkPath() and looksLikeDartSdk() — a robust runtime Dart SDK locator (in src/sdk/dart_sdk_locator.dart). The analyzer derives the SDK from Platform.resolvedExecutable, which is correct under dart run but fails for AOT-compiled tools (dart compile exe) where the executable is the tool itself, not the dart binary. The locator tries DART_SDK / DART_HOME, the resolved executable, and the dart/flutter executables on PATH (handling the Flutter bin/cache/dart-sdk layout), validating every candidate against the SDK marker file before returning it. The result is cached for the process lifetime.
• SummaryGenerator now uses resolveDartSdkPath() to locate the SDK summary directory, fixing a PathNotFoundException for lib/_internal/allowed_experiments.json when run from a compiled binary.

0.1.0

• Initial release. Extracted summary-caching infrastructure from tom_reflection_generator into a reusable library so multiple code generators (reflection, d4rt bridges, ...) can share the same <workspace>/.tom/analyzer-cache/ directory.
• Public API:
  • PackageDependency, DependencySet
  • DependencyResolver (parses pubspec.lock, locates hosted/SDK package sources)
  • SummaryCacheManager (reads/writes {name}@{version}.sum files)
  • SummaryGenerator (generates the SDK summary and per-package summaries in topological order)
  • runSummaryCacheStage() and SummaryCacheResult — reusable orchestration helper that resolves dependencies, generates missing summaries, and returns the paths to pass to AnalysisContextCollectionImpl.
