Paragraph dialog: Special box sets First line and Hanging indents - #4922
The Paragraph dialog gets Word's Special box and its By length in place of the signed First line box:
Special
By
indentFirst sent
(none)
— (disabled)
0
First line
n
+n
Hanging
n
−n
Today a hanging indent can only be set from the dialog by typing a negative First line value, which users coming from Word or WPS don't expect (they look for Special › Hanging, which is how references, numbered clauses and many Thai government documents are laid out).
How it behaves
A positive first-line indent opens as First line, a negative one as Hanging, both by a positive length.
Picking First line or Hanging from (none), or while the selected paragraphs differ, starts at 0.5" (1.27 cm), as Word does.
Switching between First line and Hanging keeps By.
Nothing changes in what the dialog sends: it is still indentFirst in para.set, so the engine, DOCX and the ruler are untouched.
Scope
Only the Indentation grid of the Paragraph dialog (dialogs/dispatch.rs, dialogs/paragraph.rs). It doesn't touch line spacing; #3777 adds the line spacing rule box (Exactly / At least…) in the same dialog, so whichever lands second has a small conflict in that grid.
New strings (English only, translations follow through craft-i18n): Special:, (none), First line, Hanging, By:.
Tests
dialogs::tests::paragraph_dialog_sets_first_line_and_hanging_indents drives the dialog through kittest: picks Hanging (0.5"), changes By, switches to First line (By kept), back to Hanging, OK → indent_first == -54 pt; reopening shows Hanging by 0.75"; (none) clears it. While writing it, it caught a bug of my own where the By box wrote back the previous kind in the frame a new kind was picked.
Added a Special indentation control to the Paragraph dialog, with options for no indent, First line, and Hanging.
Set the indent amount using the By field. Choosing First line or Hanging from no indent starts at 0.5 inches, and switching between the two preserves the amount.
Committed By edits update the indent amount; uncommitted edits do not. The By field is unavailable when no indent is selected.
Different indent settings across selected paragraphs appear as a mixed value. Choosing an indent type or editing the amount applies a consistent value to the selection.
Word's Paragraph dialog sets the first-line indent with a Special box
((none), First line, Hanging) and a By length. WordCraft had a single
signed First line box, so a hanging indent had to be typed as a negative
number. The dialog now has Special and By in its place: a positive
first-line indent shows as First line, a negative one as Hanging, both by
a positive length. Picking a kind from (none), or while the selected
paragraphs differ, starts at 0.5" as Word does, and switching between
First line and Hanging keeps By. What the dialog sends (`indentFirst`)
is unchanged.

Walkthrough
The Paragraph dialog replaces its signed first-line indent field with a Special selector and a By amount field. The controls support no indent, First line, and Hanging. Tests cover selection, amount editing, mixed values, and preserving existing indents.

Summary
Special indent control crates/ui-egui/src/dialogs/paragraph.rs, crates/ui-egui/src/dialogs/dispatch.rs, crates/ui-egui/src/dialogs/tests.rs, ROADMAP.md, docs/ui-parity.md
The dialog adds a Special selector and By field. Selecting First line or Hanging from no indent starts at 0.5 inches in the current unit. Switching between indent types preserves the amount. Committed By edits apply the amount. Tests cover mixed selections, unchanged values, and applying Hanging to selected paragraphs. Documentation records the behavior.

Before / after behavior
observed — Modified behavior in crates/ui-egui/src/dialogs/paragraph.rs: Added para_special to display and edit first-line indentation kind and magnitude. It maps positive, negative, and zero values to First line, Hanging, and (none), respectively; mixed values display blank. Choosing a non-none kind from blank or none initializes the magnitude to half an inch in the current unit, while switching between First line and Hanging retains it. The By field is disabled for blank or none, and committed edits preserve the selected kind's sign and clear the mixed state.
observed — Modified behavior in ROADMAP.md: The latest-update banner adds the Paragraph dialog’s Special box change as the current trivial update; the prior undefined-style update moves into the previous-change history.
observed — Modified behavior in ROADMAP.md: Adds a progress-log entry describing First line and Hanging indent choices, the 0.5-inch initial By value, retaining By when switching kinds, and applying typed values after commitment.
observed — Modified behavior in ROADMAP.md: Adds a trivial revision-history entry for the Paragraph dialog’s Special box setting First line and Hanging indents.

Drive the By value and the (none) choice through the UI in this test.
The test covers the Special combo for Hanging and First line. It does not cover the By control or the (none) choice. Two steps write first directly. Because of this, a regression in the By control or in choosing (none) would not fail the test.
Apply this change:
Set By through its widget, not by writing Dialog::Paragraph { first }.
Choose (none) through the Special combo, not through ok_edit.
Assert indent_first after each step.
Other tests in crates/ui-egui/src/dialogs do not click the Special combo or the By control. The gap is limited to this test.

CodeRabbit on storytold#4922: the By box took each key as it was typed, so
replacing 0.5 with 0.25 set By to 0 at the first key, which turned
Special to (none) and disabled the box mid-typing. By now commits on
Tab or focus loss. The test drives By and (none) through the dialog and
fails without the fix (-0.0 vs -0.5 after typing "0"). docs/ui-parity.md
records the Special box.

@coderabbitai The nitpick on paragraph_dialog_sets_first_line_and_hanging_indents is done in 6b0f4d9: By is set by typing into its box (not by writing first), (none) is picked from the Special combo on the reopened dialog, and indent_first is checked after each OK. Main is merged in 81fe93e (docs status lines only). cargo test -p wordcraft-ui-egui passes (1013), clippy and fmt are clean.
Add mixed first-line indents to the Paragraph dialog UI test.
The new UI test starts with one paragraph. The existing mixed-selection tests do not give the selected paragraphs different indent_first values. Add a UI case that checks unchanged OK preserves each indent and that choosing a Special kind from the blank state initializes By to 0.5 inches.

@pakiat Thanks for the update. The changes you describe in 6b0f4d90 address the test-coverage nitpick: the test types into By, selects (none) through the reopened Special combo, and checks indent_first after each OK.
Noted the main merge in 81fe93ea and your reported 1,013 passing tests, clean clippy, and clean formatting. I have not independently rerun those checks.
📝 I couldn't check this conversation for new learnings, so no new learning was saved.
CodeRabbit nitpick on storytold#4922: selected paragraphs with different first-line
indents show Special blank, an unchanged OK keeps each indent, and picking
Hanging from the blank box sets half an inch for all of them.

@coderabbitai The mixed-selection nitpick is done in 2e5f199: paragraph_dialog_special_box_over_differing_first_line_indents selects paragraphs with first-line indents of +18 pt, −18 pt and none. Special shows blank, an unchanged OK keeps each indent, and picking Hanging from the blank box sets −0.5" (−36 pt) on all three. The dialog tests pass (145), clippy and fmt are clean.
On the related issues: #4541 asks for first-line indents in characters (w:firstLineChars), which this PR doesn't add; the By box uses the measurement unit from Options, as Left and Right do.
For best results, initiate chat on the files or code changes.
@pakiat The changes you describe in 2e5f1996 address the mixed-selection nitpick. The test covers preserving each indent after an unchanged OK and applying −36 pt to all three paragraphs when Hanging is selected from blank Special.
Noted your report of 145 passing dialog tests and clean clippy and formatting checks. I have not independently rerun those checks.
Agreed that #4541 remains separate: character-based indents (w:firstLineChars) are outside this PR’s scope. By uses the measurement unit from Options, consistent with Left and Right.

ReviewerA — source-read COMMENT (not an approval)
I read the first hunk: the Paragraph dialog imports para_special, and per the title its Special box (None, First line, Hanging) sets the First line and Hanging indents, as Word's dialog does. The two are exclusive and the "By" value is a positive distance whose sign is derived from the kind, so the model (a signed first-line indent) must round-trip: a paragraph with a negative first-line indent opens with Hanging and the positive value. I did not read para_special. Add tests for opening a paragraph with each of the three, changing the kind (the By value is kept), "None" (zero), a mixed selection (blank, not forced), and units (cm, in, pt). Nothing was run.
I ran nothing and have no exact-head CI result for this PR, so this is not an approval. Where a diff was long I read its code hunks rather than every generated or documentation line.
Review: a first-line indent opens as First line by its size; By reads and takes lengths in the measurement unit.

paragraph_dialog_sets_first_line_and_hanging_indents: Hanging starts at 0.5"; a typed By counts once committed; switching First line ⇄ Hanging keeps By; reopening a hanging paragraph shows Hanging by 0.75"; (none) sets 0.
