Preserve Arabic cell direction and RTL sheet layout in PDF exports - #955
Stacked on #940. It contains all of #940 (Arabic shaping in PDF) and adds cell direction and right-to-left sheet geometry (M12.AR5). Review the diff against #940's branch; once #940 merges, this PR is up to date with it.
Summary
PDF export now honors cell Context, Left-to-Right and Right-to-Left settings. Wrapped lines keep their paragraph direction. Right-to-left sheets place columns, repeated headings, merged cells and objects in the same order as the grid, and explicit Left and Right alignment stay on the side the grid shows them.
PDF export
- infer each line separately; place every sheet left to right+ preserve cell direction across lines; mirror RTL sheet positions+ reject oversized text before appending an incomplete PDF block
Depends on #940 (Arabic PDF glyphs). The cell reading direction it reads landed with #947.
Evidence
Before: PDF ignored explicit reading order and RTL sheet layout. A public size-limit probe returned a PDF with an unmatched marked-content block. After: Direction, wrapped paragraphs, numeric brackets, RTL columns, headings, objects, clipping and sparklines have focused regressions. The same size-limit probe returns an error; its regression failed before the fix and passes afterward.
At the current head, with Noto Sans Arabic installed and no CRAFT_FONTS_DIR: the gridcraft-pdf and gridcraft-engine tests, workspace clippy and fmt pass. The full cargo xtask ci with the craft-fonts bundle relies on the hosted gate.
Poppler rendering inspected for LTR and RTL sheets. Bounding boxes confirm reversed column positions; logical Arabic strings remain searchable. No physical printer test.
Merge Danger
Door: Two-way. Revert the commit to restore prior export behavior.
Blast Radius: PDF. Explicit cell direction is shared with XLSX persistence. Latin text retains the standard-font path, including forced RTL numeric text without an Arabic font.
Summary by CodeRabbit
New Features
PDF exports now shape Arabic text and preserve its searchable logical text, alongside mixed right-to-left and left-to-right content.
Right-to-left sheets now mirror page layout, including cells, drawings, headings, and link targets, while keeping text readable.
Arabic fonts are used when available; exports fall back to standard fonts when needed and display a message if no Arabic font is available.
Bug Fixes
Text wrapping, alignment, spacing, and cell reading direction now account for text direction and Arabic glyph dimensions.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
PDF export now supports shaped Arabic text, direction-aware layout, and mirrored right-to-left sheets. The engine wraps and draws text using resolved direction. PDF finalization returns errors and Arabic-font fallback status.
Changes: Arabic PDF and RTL Export
Layer / File(s)
Summary
Arabic font inputs and glyph shaping crates/pdf/build.rs, crates/pdf/Cargo.toml, crates/pdf/src/arabic.rs, ATTRIBUTION.md, crates/pdf/README.md
The PDF crate validates bundled Arabic-font inputs, selects bundled or installed faces, shapes Arabic text, and writes Type3 subsets with Unicode mappings. Attribution and package descriptions document the font inputs and Arabic output.
Direction-aware PDF drawing and errors crates/pdf/src/lib.rs, crates/pdf/src/tests.rs
The PDF API measures and draws text by direction, tracks rendering errors, and includes Arabic font resources. PdfDoc::finish returns a result; tests cover shaping, direction, mappings, and limits.
Direction-aware text layout and wrapping crates/engine/Cargo.toml, crates/engine/src/cmd/print/text.rs, crates/engine/src/cmd/print/objects.rs, crates/engine/src/cmd/print/tests.rs
The engine resolves text direction per paragraph, wraps at grapheme boundaries, and applies direction-aware measurements and drawing to cell text and shape text. Tests cover Arabic output, reading order, wrapping, and text direction.
RTL sheet geometry and PDF export integration crates/engine/src/cmd/print.rs, crates/engine/src/cmd/print/draw.rs, crates/engine/src/cmd/print/objects.rs, crates/engine/src/cmd/print/tests.rs, ROADMAP.md, docs/*
The engine mirrors RTL sheet content, objects, and link targets. PDF export returns page count and Arabic-font fallback status, and queues a message when Arabic-font support is unavailable. Tests and documentation record the export behavior.

The reviewed paths preserve workbook protection and prevent rendering failures from publishing incomplete exports. No introduced security flaw was established. Font-dependent behavior and compatibility with external callers remain verification limits.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The inspected attacker-controlled surface is workbook text and formatting processed by an export operation. Failures affect that operation and its prospective output; font caches are process-wide, while page content and glyph subsets belong to individual pages. Deployment-level tenant isolation and maximum aggregate export exposure are not established by the supplied evidence.
Trust Boundaries and Controls
observed — Workbook text can trigger Arabic font processing but does not supply the font pathname in the inspected loader. Build-bundle paths are canonicalized and constrained to the configured root, with checksum and glyph-coverage validation. Native fallback reads recognized filenames from system and environment-derived font directories with a 64 MiB input limit.
Resilience and Maintainability Implications
observed — Arabic processing limits each input line to 128 KiB and each page subset to 16,384 distinct glyph entries and 64 MiB of tracked outline/source data. Text drawing checks the complete generated block against the page-content limit before appending it and records failure for finalization. These are local bounds, not a demonstrated aggregate CPU or memory budget for an entire export.

The title "Preserve Arabic cell direction and RTL sheet layout in PDF exports" matches the main changes in the changeset. The raw summary shows Arabic PDF shaping, cell reading direction preserved through wrapping and drawing, and RTL sheets mirrored across print drawing, objects, text, and links. The title is specific, single-sentence, and free of file lists or vague terms. The title is slightly long at 66 characters, but it stays clear and readable.

Mirror hyperlink rectangles and internal link targets on RTL sheets.
When sh.right_to_left is true, draw_block_links still uses b.rect(cell_range) and unmirrored block bounds. The annotation can cover the wrong cell. printed_target also uses the unmirrored PrintedBlock.x, so internal links can land at the wrong horizontal position.
Use b.drawn_rect(cell_range) and mirror the block bounds. Store the mirror axis and sheet direction in PrintedBlock, then mirror the target x-coordinate by the target cell width.

@coderabbitai Thanks, valid: PDF hyperlinks (#954) landed on main after this PR was written, so they weren't mirrored. Fixed in d594c95:
draw_block_links mirrors each clipped link rectangle with b.text_x. Clipping before mirroring gives the same box, since the block bounds mirror with it.
PrintedBlock keeps mirror_axis: Option<f32> (set only for right-to-left sheets), and printed_target mirrors the target cell's left edge by its width.
New test right_to_left_sheets_mirror_link_rectangles_and_targets exports the same sheet left-to-right and right-to-left and checks that the link /Rect and the /XYZ target mirror about the page width. It fails without the fix.
For best results, initiate chat on the files or code changes.
@Mouhand-Kaddo Thanks for the detailed update. Based on your description, d594c95 addresses both hyperlink rectangles and internal link destinations on RTL sheets.
The LTR-versus-RTL regression test covers both /Rect and /XYZ coordinates. I have not independently verified the commit or test result.

… lacks a character or is missing (review)
Characters the Arabic face lacks are drawn the way non-Arabic text is
(standard fonts or the CID font). With no bundled or installed Arabic
face, Arabic text takes the standard-font path and the export shows a
message once. Only a broken font or a size limit still fails the export.
🤖 Claude Opus 5.5 responding on behalf of Mouhand-Kaddo
This branch now includes #940's fixes for both P1s (merged in 816a6c0), so the two points you said it inherits no longer apply. A character the Arabic face lacks falls back like non-Arabic text, and a missing Arabic font exports ? with a message instead of failing.
With #947 merged, this diff is now #940 plus this PR's print and PDF direction commit. The merge needed one follow-up: the RTL mirroring test read render_pdf's old tuple result and now reads .bytes (0d7334a). The gridcraft-pdf and gridcraft-engine tests and clippy (pdf, engine, ui-egui) pass locally. The Hebrew-through-CID gap you noted is unchanged.
Main's PDF writer now writes each object straight into the output and
tracks the graphics state (storytold#816). The Arabic subset fonts are written
with the same stream and dictionary helpers, the shaped-text block sets
its colours with push_rgb, and it is dropped at the 28-level q limit
like an image. Main's newer PDF tests read finish()'s Result.
…-direction
Brings in main through storytold#940. The direction-aware text paths keep their
split into shaped and standard text on main's writer: the standard path
sets its colour through the tracked style and its matrix after the first
font, the shaped path respects the q nesting limit, and WordArt shadows
and outlines are drawn with each line's direction. The RTL sparkline test
finds the path line now that line styles follow the stroke colour.

…edit
Without an Arabic face for the text's weight, Arabic is set in the CID
font, which has no Arabic glyphs, so readers show blanks or boxes rather
than `?`. The export message no longer says `?` or "not installed": it
also appears for bold text with only the regular face, and on the web,
where the font is not bundled. The docs say the same.
The VML pass-through assertion is back to main's version, and the line
comments this PR added are removed.
…-direction
Brings in storytold#940's corrected no-font message and docs. Conflicts keep this
branch's direction-aware code without the line comments storytold#940 removed;
the two comments this PR added (sparkline mirroring, grapheme breaking)
go too. The gaps and file-format headers now name this PR's change.
…heet
The grid swaps explicit Left and Right before mirroring a right-to-left
sheet, so they land where the user put them; the PDF mirrored them
unswapped, printing Align Left on the right. text_align now swaps them
the same way. General alignment is unchanged.
Without a face the text takes the standard-font path, which has no
128 KiB shaping limit, so the export succeeds; the test checks that PDF
instead of expecting the error.

… width
Without an Arabic face, text_width sums the standard widths instead of
returning zero, so the old guard never skipped and the tests failed on
a machine without the font. They now ask PdfDoc::missing_arabic_font.

Remove the completed Arabic PDF work from this remaining-work list.
Line 57 limits the PDF gap to scripts outside Arabic. Line 67 confirms Arabic shaping and RTL export. However, this second Missing entry still lists unrestricted “non-Latin PDF” work. Consolidate the two Missing entries so contributors do not select completed Arabic PDF work.
As per coding guidelines, gaps.md is the “ranked work list: pick from it.”

Review comment at @docs/gaps.md at line 62:
Update the “Missing” entry in the remaining-work list to exclude completed Arabic PDF work and consolidate it with the other PDF gap entry, while retaining the still-missing CJK fallback, complex shaping for other scripts, bidi, and non-Latin PDF work that remains outstanding.

@coderabbitai Valid, fixed in 028d80a: the second Missing entry in docs/gaps.md §5 now says "non-Latin PDF outside Arabic", matching the first. Merging the two entries is left alone here; the duplicate came from main, not this PR.

Stacked on #940. It contains all of #940 (Arabic shaping in PDF) and adds cell direction and right-to-left sheet geometry (
M12.AR5). Review the diff against #940's branch; once #940 merges, this PR is up to date with it.Summary
PDF export now honors cell Context, Left-to-Right and Right-to-Left settings. Wrapped lines keep their paragraph direction. Right-to-left sheets place columns, repeated headings, merged cells and objects in the same order as the grid, and explicit Left and Right alignment stay on the side the grid shows them.
Depends on #940 (Arabic PDF glyphs). The cell reading direction it reads landed with #947.
Evidence
After: Direction, wrapped paragraphs, numeric brackets, RTL columns, headings, objects, clipping and sparklines have focused regressions. The same size-limit probe returns an error; its regression failed before the fix and passes afterward.
CRAFT_FONTS_DIR: thegridcraft-pdfandgridcraft-enginetests, workspace clippy and fmt pass. The fullcargo xtask ciwith the craft-fonts bundle relies on the hosted gate.Merge Danger
Door: Two-way. Revert the commit to restore prior export behavior.
Blast Radius: PDF. Explicit cell direction is shared with XLSX persistence. Latin text retains the standard-font path, including forced RTL numeric text without an Arabic font.
