v0.26.0

Text drawn where it is laid out. Registered fonts now keep their kerning, justification and mark placement on the page, right-to-left text reads in the right order, lines stay inside their boxes, and tagged output stops nesting its marked content. All packages share the line: engine (crates.io forme-pdf), every @formepdf/* npm package, formepdf (PyPI), forme-go (tag v0.26.0), and the VS Code extension.

Fixes the six externally reported issues #156, #157, #158, #159, #160 and #161, and #162.

Changed: these move existing documents

• Registered fonts are drawn at their laid-out positions. Layout placed shaped glyphs with the shaper's advances and the Knuth-Plass positions, but the writer drew each run as one plain Tj, so a viewer advanced every glyph by the font's own width and dropped the rest. Measured in Liberation Sans, the font every PDF/UA and PDF/A document embeds: a 24pt kerning line drawn 17.8pt wider than laid out, justified paragraphs drawn ragged (Tw does not apply to Type0 fonts, ISO 32000-1 9.3.3), and Hebrew points beside their letters. Registered-font text is now written as positioned TJ arrays, with Ts for marks the shaper moves vertically, and /W widths are exact rather than truncated. Text with nothing to adjust keeps a plain Tj. Standard fonts (Helvetica, Times, Courier) are unchanged. Output in registered fonts grows about 1%
• Right-to-left text reads in the right order. The shaper returns an RTL run in visual order and the BiDi reordering reversed it again, so Hebrew was drawn backwards; and a line mixing RTL text with a number or a Latin word was never reordered at all. Both are fixed, checked against Chrome's glyph order. Arabic now extracts identically to Chrome. Hebrew points keep the shaper's placement through the reordering
• Ragged-right lines stay inside their box. Knuth-Plass let word spaces shrink when choosing breaks for every alignment, but only justified text narrows its spaces when drawn, so a left-aligned line could run a few points past its box. Spaces are now incompressible unless the text is justified, and the letter-spacing after a line's last character, which paints nothing, no longer decides whether the line fits. Some paragraphs re-break; the new breaks match Chrome's
• Justified text. A justified paragraph's last line used to inherit the previous line's word spacing (#162). Underlines and strikes on justified lines, and inline link click areas, no longer count the word spacing twice
• HTML margin boxes are sized by the boxes present. Each was a fixed third of the edge, so a lone @top-center header wider than a third wrapped where Chrome keeps it on one line. A lone box, or a centre box without side boxes, now takes the whole edge, and side boxes without a centre split it
• Fixed headers, footers and watermarks inherit the document's style (#160). On the HTML path, margin boxes inherit from the page, not <body>, as CSS specifies
• Tagged output no longer nests marked content. An element kept its marked-content sequence open while its children were written, so nearly every sequence sat inside another and a table cell's text belonged to its cell and its row at once. Wrapper elements now carry no content of their own and box ink is marked as an artifact. veraPDF's "Nested MCID" warnings on the corpus go from about 10,000 to 0, and tagged files are about 5% smaller. Inline link text is now tagged inside its /Link element (#157)
• A component that returns an array or fragment renders (#159), and a Page returned by a component at the Document level becomes a real page

Fixed

• Ligature glyphs copy as their whole text in ToUnicode (#156)
• Inline links inside text get link annotations (#157)
• Document info strings (title, author, outline titles) are encoded correctly, and DocInfo and XMP agree on the producer (#158)
• Lists keep .map() and component children in template mode (#161); a child a list still drops is reported in the render warnings
• DotPlot draws its yLabel, and both axis titles get room beside the tick labels
• Knuth-Plass hyphen_penalty is applied
• A link nested inside a different link is reported instead of dropped silently
• Two Northmoor templates' totals tables fill their column, and the termination letter's prose is widened to stay on one page

Added

• The HTML dir attribute and CSS direction property. Correction: the 0.24.0 notes said dir="rtl" reached the engine's BiDi. It did not: the attribute was copied onto <body> and never mapped. It is mapped now

Internal

• The CLA workflow no longer locks pull requests when they close
• Visual tests keep concurrent runs' temporary files apart
