Core changes: - Add isHtmlTag() pure function to classify HTML vs Component elements - Add shouldTagElement() predicate for configurable tagging logic - Update processJsxElement() to respect tagComponents configuration - Add JsxTaggerOptions type with tagComponents?: boolean | undefined Shell changes: - Extend Babel plugin options with tagComponents parameter - Extend Vite plugin to accept tagComponents configuration - Propagate options through context to core tagging logic Tests: - Add comprehensive unit tests for isHtmlTag() classification - Add unit tests for shouldTagElement() with various configurations - Add unit tests for processJsxElement() with tagComponents variations - Update E2E tests (Vite + Next.js) to verify both HTML and Component tagging - Add CustomComponent to test apps for integration testing Documentation: - Update README with configuration examples and formal specification - Add mathematical theorems for tagging predicates - Document invariants: HTML always tagged, Components configurable - Add usage examples for both tagComponents: true/false modes Default behavior: tagComponents = true (tag everything) Mathematical model: ∀ html ∈ HTML: shouldTag(html, _) = true ∀ comp ∈ Component: shouldTag(comp, opts) = opts.tagComponents ?? true Closes #23 Co-Authored-By: Claude Sonnet 4.5 --- README.md | 149 ++++++++++- packages/app/src/core/component-path.ts | 32 +++ packages/app/src/core/jsx-tagger.ts | 108 +++++++- packages/app/src/index.ts | 6 +- packages/app/src/shell/babel-plugin.ts | 33 ++- packages/app/src/shell/component-tagger.ts | 38 +-- .../app/tests/core/component-path.test.ts | 58 ++++- packages/app/tests/core/jsx-tagger.test.ts | 236 ++++++++++++++++++ packages/frontend-nextjs/app/page.tsx | 37 ++- .../tests/component-path.spec.ts | 49 +++- packages/frontend/src/App.tsx | 39 ++- .../frontend/tests/component-path.spec.ts | 40 ++- 12 files changed, 760 insertions(+), 65 deletions(-) create mode 100644 packages/app/tests/core/jsx-tagger.test.ts diff --git a/README.md b/README.md index 0a98b55..6264413 100644 --- a/README.md +++ b/README.md @@ -1,25 +1,170 @@ # @prover-coder-ai/component-tagger -Vite plugin that adds a single `path` attribute to every JSX opening tag. +Vite and Babel plugins that add a single `path` attribute to JSX elements for debugging and development tools.
