feat(ui-tui): right-to-left text shaping (§8 bidi) - #529
Merged
Conversation
Port RTL/bidi handling as a pure-TS shaper (no deps). src/bidi.ts reverses RTL runs (Hebrew/Arabic, incl. presentation forms) into visual order within LTR-base text, keeping digit sub-runs in logical order — the common case (RTL words in otherwise-LTR content) on terminals without native bidi. Opt-in via /rtl (and CLAWCODEX_RTL=1) since bidi-capable terminals would otherwise double-reorder. Scoped honestly: not full UAX #9 (no base-RTL paragraph resolution / nested levels). Display-only — stored entry text stays logical, so /export and /copy are unaffected. Verified: bidi unit cases (RTL word reversed, spaced run, digits keep order, no-RTL untouched); in-app /rtl toggles and a Hebrew assistant line renders reversed while the logical form is not shown.
