pretext

Fixed

• Streaming line layouts and line statistics now agree with batch layout when a later break follows a soft hyphen. Streaming also retains later text after consecutive lines containing only invisible break controls (#222).
• Terminal soft hyphens now stay invisible and preserve terminal letter spacing across the rich line APIs.
• Rich bidi metadata now resets independently at each paragraph boundary.
• Rich-inline preparation with long internal whitespace, streaming layout of long hyphenated runs, and long font-size strings now avoid excessive repeated work (#221).
• Rich-inline cursors now retain original item indices across empty items, zero-width items can occupy a line, and boundary spaces preserve their font and signed letter spacing. Mutating a visited line no longer changes the walker's continuation (#220).
• Overlong independent symbol runs can now wrap at grapheme boundaries, with browser-specific punctuation attachment (#208).
• Numeric minus signs no longer introduce a preferred break before their number, and ASCII hyphens after CJK text stay attached to the preceding character (#213, #215).
• The Markdown chat demo now keeps ordinary text inside its bubbles in Firefox on macOS (#202).

Added

• The published package now ships declaration maps, so editor go-to-definition and programmatic TypeScript source tracing land in the shipped .ts source instead of the .d.ts files.

Fixed

• Word-internal keyboard and Unicode symbol runs in long words now stay with surrounding text the way browsers break them, while browser-break symbols stay breakable (#169).
• Overlong hyphenated runs now prefer browser-like dash breakpoints before falling back to emergency grapheme breaks (#89).

Changed

• The package now declares itself side-effect-free so bundlers can tree-shake unused entrypoints (#160).
• layoutNextLine() and layoutNextLineRange() now avoid redundant chunk lookup in chunk-heavy manual layout paths (#140).

Fixed

• { wordBreak: 'keep-all' } now handles no-space mixed Latin, numeric, and CJK text more like browsers.
• No-space punctuation chains now stay together for non-ASCII word-like text too, instead of only ASCII words.
• Opening punctuation such as ¡, ¿, German low quotes, and ⸘ now stays with the following word instead of dangling at line end (#165).
• Numeric prefix/postfix symbols like $, %, €, +, −, and ° now stay attached to adjacent text the way browser line breaking does (#105).
• Soft-hyphen breaks now stay at the soft-hyphen insertion point instead of pulling post-hyphen graphemes onto the broken line (#162).
• Line geometry now preserves browser-style terminal letter spacing, including rich-inline item boundaries and visible soft-hyphen breaks (#171).
• Rich-inline item boundaries no longer overflow the requested width after a forced-progress break (#132).
• The markdown chat demo now drops parsed link URLs unless they resolve to HTTP(S) hrefs (#168).

Added

• Numeric CSS-pixel letterSpacing support on prepare(), prepareWithSegments(), and each existing rich-inline item (#108, #156).

Fixed

• CJK text followed by opening bracket annotations now wraps like browsers instead of leaving the opening bracket on the previous line (#148).

Added

• Geometry-first rich line helpers for manual layout work: measureLineStats(), measureNaturalWidth(), layoutNextLineRange(), and materializeLineRange().
• @chenglou/pretext/rich-inline, a narrow helper for inline-only rich text, mentions/chips, and browser-like boundary whitespace collapse.
• { wordBreak: 'keep-all' } support on prepare() / prepareWithSegments() for CJK and Hangul text.
• A virtualized markdown chat demo for rich inline text and pre-wrap layout.

Changed

• Prepare-time analysis is more resilient on long mixed-script, CJK, Arabic, repeated-punctuation, and other degenerate inputs.

Fixed

• Mixed CJK-plus-numeric runs, keep-all mixed-script boundaries, and long breakable runs now stay closer to browser behavior.
• Rich-path bidi metadata and CJK detection now handle the relevant astral Unicode ranges correctly.

Added

• A justification comparison demo that shows native CSS justification, greedy hyphenation, and a Knuth-Plass-style paragraph layout side by side.

Changed

• Rich layout is faster on chunk-heavy and long-breakable text.

Fixed

• layout(), layoutWithLines(), and layoutNextLine() stay aligned on narrow ZWSP / grapheme-breaking edge cases.
• The justification comparison demo no longer paints justified lines wider than their column.
