- hyphen: bundled en-US dictionary from the public-domain Moby Hyphenator II
list (Grady Ward, Gutenberg #3204), front-coded + deflated (433 KB), with
case/apostrophe/punctuation/compound handling and inflection inheritance;
our own Liang patterns (19.5k, 129 KB) trained by a patgen-style trainer
(hyphen::patgen, examples/hyphgen.rs) for unknown words; heuristic last.
Discretionary hyphens replace automatic points.
- breaker: prioritised word/letter/glyph-scaling glue in Knuth-Plass and
layout; uncapped badness; hyphen limit as a hard constraint (hyphen-count
states); hyphenation zone for ragged text (both composers); ragged
hyphenation measured correctly; optical margin alignment; balance ragged
lines; Knuth's node pruning.
- compose: Keep Options (keep with next, keep all lines, keep first/last)
via paragraph snapshots; desired spacing applied to all alignments;
justified last lines shrink instead of overflowing; word shaping and
hyphenation caches (300k-char story: ~40 ms warm, ~60 ms cold).
- tests: golden corpus, perf (ignored), keeps, balance, optical, zone,
limit, letter/glyph scaling, discretionary hyphens.
