Summary

  • mark the Line SVG as presentational by default, matching Circle and avoiding redundant image announcements when a wrapper owns the progress semantics
  • accept and forward standard SVG and ARIA attributes so standalone Line and Circle instances can expose role="progressbar", an accessible name, and value metadata
  • document the accessibility contract in English and Chinese and add runtime/type coverage for default and caller-overridden semantics

Verification

  • exact base: cd730a65958a2afad2ea12f6ae3a3b3a3e052650
  • regression before the fix: tests/semantic.spec.tsx failed because Line had no presentational role
  • pnpm test --runInBand — 4 suites, 19 tests, 11 snapshots passed
  • pnpm tsc — passed
  • pnpm lint — 0 errors; one pre-existing unused-disable warning in src/Line.tsx
  • pnpm docs:build — passed
  • git diff --check — passed

pnpm compile reaches declaration generation but is blocked by TS2688: Cannot find type definition file for keyv. I reproduced the same failure in an isolated worktree at the unmodified exact base, so it is not introduced by this PR.

Fixes #304

AI assistance disclosure: Codex was used to trace the existing SVG semantics, implement the narrowly scoped prop contract, and draft tests and documentation. The default-role regression was reproduced on the exact base and all listed checks were run locally.

6-28: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Line 增加显式进度语义测试。

当前用例只验证 <Line percent={25} /> 的默认 role="presentation"role="progressbar"、accessible name 和 aria-valuenow 只传给了 Circle。因此该用例无法验证 Line 是否允许调用方覆盖默认角色并透传 ARIA 属性。

请新增一个独立的 Line 用例,并断言 rolearia-labelaria-valueminaria-valuemaxaria-valuenow

from React.SVGAttributes before redefining them with the component-specific
number and StrokeLinecapType contract. Keep Line’s existing destructuring and
path-rendering behavior unchanged, and document that these fields are
intentionally component-specific rather than forwarded SVG attributes.
