- fix: ekp-param-set silently reset after first justify (now persists;
ekp-param-reset added)
- fix: narrow-width CJK returned empty string (data loss); two-pass
emergency-break strategy guarantees output for any input
- fix: K-P penalties never synced to C module; space-box metrics
divergence between C and Elisp engines
- fix: para cache ignored ekp-latin-lang (stale hyphenation after
language switch) and used collision-prone sxhash keys
- fix: fullwidth letters/digits misclassified as CJK punctuation
- fix: combining chars split from their base char in the tokenizer
- fix: punctuation-wrapped words (word!/(word)/word;) never hyphenated
- fix: renderer double-counted stripped space widths; negative glue
clamped; batch/tty font detection no longer crashes
- feat: real looseness support via (position × line-count) DP
- perf: O(1) line metrics and gap counts via prefix arrays (inner loop
previously allocated O(n) subsequences → O(n³) total); box measurement
dedupe; eq fast-path para lookup; prebuilt per-para glue arrays
→ zh justify 7547ms → 96ms (compiled elisp) / 57ms (C);
range-justify 68.5s → 0.48s / 34ms; C module itself 3–19× faster
- test: 36 batch-safe ERT tests + 300-case property fuzz (C/elisp
byte-identical output, zero content loss) replacing ad-hoc suite
- docs: readme/readme_zh/DEVELOPER/DEVELOPER_ZH/ekp_c-README rewritten
to match the implementation; phase handoff in .phrase/phases/
BREAKING: requires Emacs 29.1+; C module must be rebuilt (v1.1, new
arities); ekp-threshold-factor / ekp-flagged-penalty /
ekp-forced-break-penalty removed; Rust module stubs removed.
