📝 Walkthrough

Walkthrough

The .code function now supports line callouts. Quarkdown validates and propagates callouts, renders HTML markers and descriptions, applies client-side markers, styles the output, and adds coverage. Code enhancement logic is split into feature classes. The mock CLI configuration no longer passes an explicit library path.

Changes

Code callouts and enhancement pipeline

Layer / File(s) Summary
Callout contract and AST propagation
quarkdown-core/..., quarkdown-stdlib/...
The .code function accepts callouts keyed by positive line numbers. The AST stores and serializes the callout map.
Code enhancement pipeline
quarkdown-html/src/main/typescript/document/handlers/capabilities/...
Code highlighting delegates line numbering, focus ranges, callout markers, and copy-button registration to separate feature classes.
HTML output and styling
quarkdown-html/src/main/kotlin/..., quarkdown-html/src/main/scss/...
HTML output includes callout metadata and escaped descriptions. SCSS styles markers and the callout list.
Validation, examples, and documentation
quarkdown-*/src/test/..., docs/code.qd, CHANGELOG.md, mock/code.qd
Tests cover callout numbering, invalid lines, scoping, focus ranges, file content, language matching, and script escaping. Documentation and examples describe callouts.

Mock CLI configuration

Layer / File(s) Summary
Mock CLI run configuration
.run/CLI_Mock.run.xml
The mock CLI configuration removes the explicit --libs library-path argument.

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

Merge Risk: 🟡 Moderate · up to 889c6

The PR adds code callouts, but the current head still lacks the required document-type coverage for focus behavior and retains shared run configurations that are non-portable and ambiguously named. These issues can miss regressions and make local execution unreliable or confusing, so merge should wait for fixes or explicit owner acceptance.

Poem

A rabbit marks each code line bright
With numbered hops in circles of light
Notes gather below in a tidy row
Safe escaped words tell what they show
The mock CLI skips the library path

Inline comments:
In @.run/CLI_Mock.run.xml:
- Around line 4-6: Remove the hard-coded Homebrew-specific NODE_PATH,
PUPPETEER_CACHE_DIR, and QD_NPM_PREFIX environment entries from the shared
CLI_Mock run configuration. Keep them only in a local configuration or replace
them with project-relative or user-provided paths.
- Line 17: Rename the second run configuration’s name from “CLI: Mock” to a
distinct descriptive name that reflects its command, while leaving the
configuration type and other settings unchanged.

In `@quarkdown-html/src/main/scss/components/_code.scss`:
- Around line 76-77: Update the SCSS around the global-font-family mixin and
background-color declaration: remove parentheses from the argumentless
font.global-font-family mixin invocation and add the required blank line before
background-color to satisfy Stylelint.

In
`@quarkdown-html/src/main/typescript/document/handlers/capabilities/code/focus.ts`:
- Around line 51-52: Update the focus range parsing in the handler around
isLineInFocusRange so absent data-focus-start or data-focus-end attributes
remain NaN instead of defaulting to 0, preserving open-ended ranges through the
end or from the beginning as documented. Add tests covering both start-only and
end-only focus attributes.

In `@quarkdown-html/src/test/e2e/code/callouts/callouts.spec.ts`:
- Line 6: Replace the direct test(...) declaration in the callouts E2E test with
the repository’s testMatrix pattern, specifying the required document types
while preserving the existing test body and assertions.
