- tools/ExtractMethod: net10.0 console app (Microsoft.CodeAnalysis.CSharp
5.9.0, pinned latest stable). CLI: <file.cs> <startLine> <endLine>.
Parses the file, builds a scratch compilation with refs from
TRUSTED_PLATFORM_ASSEMBLIES, and reports how many whole statements the
line range covers (clean error otherwise; exit codes: 0 ok, 1
resolution error, 2 usage).
- Tooling/CompilationLoader: shared parse + compilation path for CLI and
tests (tests exercise the exact loading path the CLI uses).
- Tooling/SelectionResolver: snaps a 1-based inclusive line range to
whole statements in the enclosing method body block; boundary checks
never split a statement; nested/blank-line ranges handled cleanly.
- tests/: ExtractMethod/Fixtures/Demo.cs checked-in fixture exercising
every bucket of the parent spec (read-only local, written+read-later
return, scratch local, param read, field+property access, indexer +
method invocation, multi-statement range incl. a for-loop); excluded
from project compilation, copied to output as data.
- Tests: Demo.cs compiles with no diagnostics; range 68..72 resolves to
2 statements (LocalDeclarationStatement, ForStatement); AnalyzeDataFlow
succeeds on the fixture's for-loop node; mid-statement range fails
cleanly. 30/30 green.
