- ExtractFirstScanner: reads-only scan of non-local/param read expressions
(member/field/property access, element access, invocation, cast), deduped
by symbol+text with occurrence counts; invocations flagged (hoisting
changes eval count); own-class field/property reads marked optional.
Assignment LHS skipped whole (decision 5) — surfaced as a report note.
- SignatureBuilder: promotes bucket overlaps into one coherent signature
(declared-inside vars drop from params; declared-inside return candidates
become the return; outside candidates already covered by their ref
write-back stay ref params). Trailing composite returns stay void with a
note suggesting an extract-variable first.
- ExtractionReporter + ReportFormatter: single composition shared by CLI and
tests; report = header, params (ref), returns, locals, extract-first
(count + flags), notes, suggested-signature line last.
- DataFlowClassifier: Returns now carry types (ReturnSuggestion) — the
signature line needs them.
- Displays: compact symbol/type formatting for the report.
- Fixture: RepeatReads (dedupe ×2 + skipped field write), Casts (cast
candidate) appended at the end so all pinned line numbers stay put.
- 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.
