sweeper 0.4.2

Finds and removes unused gen-l10n translation keys from ARB files using resolved static analysis.

Changelog

0.4.2

• Internal: stricter lint rules and style cleanups; no functional changes.

0.4.1

• clean no longer rewrites ARB files it removed nothing from: untouched files stay byte-identical instead of being reformatted by re-serialization.
• Hand-written Dart files inside the gen-l10n output directory (e.g. lib/l10n/l10n.dart helpers) are now scanned for key usage; only the generated <output-localization-file> and its _<locale> variants are excluded. Previously, keys used only in such files were wrongly deleted.
• tool/ scripts are now scanned for key usage.
• Invalid --keep globs report a clean error (exit 2) instead of crashing with a stack trace.
• --keep globs are case-sensitive on every platform; previously they were case-insensitive on Windows only.
• SweepEngine accepts a relative projectRoot instead of throwing a raw ArgumentError.
• Removing an ARB key with an explicit null value is now counted in the per-file removal totals.
• Atomic writes use a pid-suffixed temp file (safe under concurrent runs) and clean up the temp file on failure.

0.4.0

• New --scan/-s flag on check and clean: include additional package roots (monorepo siblings) when scanning for key usage.
• Pub workspaces are detected automatically: all workspace members are scanned for key usage, and the shared root package_config.json is found by walking up parent directories.

0.3.0

• New sort command: alphabetizes keys in all ARB files, keeping @@ headers first and @key metadata attached to its key.

0.2.2

• Widened analyzer constraint to >=10.0.0 <15.0.0 so sweeper can coexist with packages pinned to older analyzer majors (e.g. dart_code_linter). Full test suite verified against analyzer 10.0.0 and 14.0.0.

0.2.1

• README: full commands & flags reference (including --quiet).

0.2.0

• Hardened detection: the localizations class must be declared in the gen-l10n output location (output-dir or the legacy package:flutter_gen synthetic package), so identically-named classes elsewhere never count.
• Colored terminal output (ANSI auto-detected, plain when piped).
• New --quiet/-q flag on check and clean to print summaries only.
• Dartdoc for the full public API and a pub.dev example.

0.1.0

• Initial release: check and clean commands with resolved-AST unused-key detection, --keep globs, --json, --dry-run, and fail-closed behavior.
