📝 Walkthrough

Walkthrough

Adds a configurable Filler Words post-processing plugin. It removes Latin and Japanese filler words, persists settings, provides a localized WPF editor, deploys through the plugin pipeline, and adds unit-test coverage.

Changes

Filler Words plugin

Layer / File(s) Summary
Filler-word filtering engine
plugins/TypeWhisper.Plugin.FillerWords/FillerWordFilter.cs, plugins/TypeWhisper.Plugin.FillerWords/FillerWordMatcher.cs, plugins/TypeWhisper.Plugin.FillerWords/Tests/FillerWordFilterTests.cs
Normalizes filler words and removes Latin and Japanese matches with cached, language-specific matchers. Tests cover punctuation, whitespace, scripts, boundaries, and ordering.
Plugin lifecycle and settings UI
plugins/TypeWhisper.Plugin.FillerWords/FillerWordsPlugin.cs, plugins/TypeWhisper.Plugin.FillerWords/FillerWordsSettingsStore.cs, plugins/TypeWhisper.Plugin.FillerWords/FillerWordsSettingsView.xaml, plugins/TypeWhisper.Plugin.FillerWords/FillerWordsSettingsView.xaml.cs, plugins/TypeWhisper.Plugin.FillerWords/Localization/*, plugins/TypeWhisper.Plugin.FillerWords/Tests/FillerWordsPluginTests.cs
Adds host lifecycle handling, persisted settings, default restoration, localized labels, live word counts, and post-processing integration.
Plugin registration and deployment
plugins/TypeWhisper.Plugin.FillerWords/manifest.json, plugins/TypeWhisper.Plugin.FillerWords/TypeWhisper.Plugin.FillerWords.csproj, .github/workflows/publish-plugins.yml
Registers the plugin and deploys its assembly, manifest, and localization resources. Publishing resolves the filler-words project path.
Plugin test-project integration
tests/TypeWhisper.PluginSystem.Tests/TypeWhisper.PluginSystem.Tests.csproj, plugins/TypeWhisper.Plugin.FillerWords/Tests/FillerWordsLocalizationTests.cs
Includes the plugin tests and adds a project reference to the plugin project. Localization tests validate keys, translations, placeholders, and singular word-count formatting.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 6c5e2

The plugin’s localization tests currently do not run, leaving localized behavior unverified and creating a merge-readiness risk until the test is included in the executing test project or the omission is explicitly accepted.

Poem

I’m a rabbit with words in a row,
Now fillers hop out as transcripts flow.
Latin and Japanese, neat and bright,
Settings persist and defaults sit right.
Tests thump their paws: “All clear tonight!”

Add singular word-count resources.

When the configured list contains one word, these strings render 1 words and 1 Wörter. Add singular resources and select them when the count is one.

  • plugins/TypeWhisper.Plugin.FillerWords/Localization/en.json#L4-L4: add an English singular form for 1 word.

Requesting changes for the functional output issues below.

The core Windows port matches the current macOS implementation in priority, defaults, and Latin/Japanese matching. Two of these output issues are inherited from macOS rather than Windows-specific, but they still corrupt Windows output and should be covered before merge.

I also confirmed the two existing CodeRabbit findings:

  • The matcher cache key can collide between distinct configured lists and return a matcher for the wrong settings.
  • The word-count localization needs singular forms for 1 word and 1 Wort.

All current checks are green, and the 39 focused Filler Words tests pass, but they do not cover these regressions.

[P2] Preserve whitespace outside the removed match

NormalizeWhitespace rewrites the entire result after any filler match. For example, um Intro\n code block becomes Intro\ncode block, so unrelated indentation and intentional double spaces are lost. Please restrict cleanup to whitespace introduced around replaced matches, and add a regression test that preserves formatting elsewhere in the input.

[P2] Consume complete attached punctuation

The optional single [,.!?]? leaves punctuation debris for common transcripts such as Um... hello, which currently becomes .. hello. Please handle repeated punctuation and the Unicode ellipsis without consuming punctuation that belongs to surrounding text, and cover both forms in tests.

Compile and execute this localization test class.

FillerWordsLocalizationTests.cs is excluded from compilation by the project manifest test-file removal rule. dotnet test cannot execute these assertions.

Add this file to the executing test project, or move it to that project. Keep the plugin assembly exclusion if it prevents test dependencies from shipping.
