Ka with a nukta and the vowel sign I is shaped as one cluster: the vowel
sign's glyph, then the ligature of Ka and the nukta. The ligature is
neither Ka's default glyph nor an alternate, so the lookup found no
glyph for Ka: text.glyphAlternates reported the vowel sign's glyph and
text.setGlyphAlternate reported Ka's default glyph. When the cluster
holds neither, the lookup now takes the first glyph that is not drawn
for another character of the grapheme.
text.glyphAlternates reported the first glyph of the character's
cluster as the chosen glyph. A vowel sign drawn before its consonant
(Devanagari Ka with the vowel sign I) comes first in that cluster, so
the query reported the vowel sign's glyph for Ka, while
text.setGlyphAlternate reported Ka's own glyph. Both commands now take
the character's glyph by the same rule, and so does the check in
text.setGlyphAlternate that the chosen glyph is drawn.
A character that overflows its area is shaped with its grapheme, and
each character of the grapheme now keeps its own style there, so a
nukta of another size no longer makes a ligature with its consonant
that the laid-out text does not draw. A test font with a Devanagari
nukta ligature checks both.
text.setGlyphAlternate looked for the character's glyph only in a
cluster as long as the character. A character followed by a combining
mark is shaped in one cluster with the mark, so the lookup found
nothing: under a substituting feature such as salt, `gid: null`
reported the default glyph instead of the one drawn, and a request for
the default glyph changed nothing.
The lookup now also takes a cluster that holds the character's
grapheme, and in a cluster of several glyphs takes the character's
default glyph or one of its alternates. Text that overflows its area
is shaped with the whole grapheme.
Follows #5442.
- text.setGlyphAlternate keeps the default glyph as a choice when a
feature of the character's style (salt, a stylistic set) draws another
glyph for it, so the default glyph is drawn. A character that is not
laid out (overflowing text) is shaped alone in its style to decide.
gid: null reports the glyph the style draws.
- The Glyphs panel's alternates grid shows the default glyph first when
the font does not list it, so a chosen alternate can be put back.
- A test for a chosen character that starts a longer grapheme (f with a
combining acute), which is not split from its mark.
- The alternates tests in the engine hold the shared font lock while
they add fonts to the global font database.
text.startList read a negative or fractional `at` as the end of the
text, so it could remove a typed list marker there and start a list.
The `start` and `end` of text.editRange, text.getRange,
text.setRangeStyle and the type shortcut commands given an `id` read
such values as the start or end of the text.
These now return "`at` must be a whole number" (naming the key) and
change nothing. Omitted or null keys keep their defaults, and 2.0 is
read as 2.
While the Type tool edits a frame of threaded text, Select All selects
the text of every frame of the story, highlighted in each frame. The
tool edits the first frame that holds text.
- Typing, Delete and Cut replace the whole story as one undo step
(`text.editRange` takes `clear`, the other frames whose text goes).
- Copy and Cut take the whole story (`text.getRange {id, story: true}`).
- Fills and strokes, `type.step`, `appearance.copyFrom`, the Character,
Paragraph, OpenType and text style panels, the Tabs panel's tab
stops, the font menus and the Justification dialog act on every
frame's text (`text.setRangeStyle {id, story: true}` styles them in
one edit).
- A caret move, a click or a word or paragraph selection ends it.
Select All in unthreaded type is unchanged.

A stroke color given without strokeWidth left characters at weight 0, so
nothing was drawn. As paint.setStroke does, a painted stroke now gives a
run with no weight 1 pt, for the characters and for the label styles a
graph keeps; an explicit strokeWidth still sets the weight.
text.setStyle takes stroke (a color or "none") and strokeWidth (the character
stroke's weight in document points, as stroke.set gives it), with keepModel
for both colors. They apply to all the text or to the start..end range, and
to graph label styles, in the same undo step as the command's other keys.
A stroke key was ignored before.
The OpenType panel gets a Position menu after Figure, with Default
Position, Superscript, Subscript, Numerator and Denominator. `numr` and
`dnom` join the extra features (the existing bits keep their indices),
so they round-trip through the stored tags and reach the shaper.
text.setStyle and text.setRangeStyle take `featureChanges`, which turns
features on or off on top of each character's own features in one
command and keeps every tag the list does not name. The Figure menu,
the Position menu and the checkboxes send it, so on a selection whose
characters have different features each character keeps its other
features. Reset OpenType Features still sends `features`.
Catalog rows for Position:, Default Position, Numerator and
Denominator; one line each in docs/type-parity.md and
docs/target-app-parity.md.
Baseline shift now moves a character in the line's frame, outside
Character Rotation, so a positive shift moves a character up from its
line at any rotation, and the character turns about its shifted pen
position. The Touch Type tool splits a drag into its part along the line
(kerning) and its part up from the line (baseline shift) at every
rotation; before, within about 6 degrees of a quarter turn it dropped
the cross-line part.
Characters that already combine a rotation with a baseline shift are
drawn in a new position. Their stored values do not change.
- text: glyph transform order, PositionedGlyph::pivot (the turning
point), tab leaders in the same order
- tools: Touch Type splits drags against the line's up axis and measures
rotate-handle turns about the shifted pen position
- engine: text.touchType description; dy is up from the line
- docs: mcp.md Touch Type paragraph, target-app-parity.md progress line
The Character panel's All Caps, Underline and Strikethrough buttons, and
its menu's All Caps, Underline, Strikethrough, Proportional Metrics,
Tate-chu-yoko and No Break, read the first selected character's style.
With only some characters marked they could show on, and choosing one
turned the attribute off for every character. They now show on only
when every selected character has the attribute, and a click on a mixed
selection turns it on for all, as Small Caps and Standard Vertical Roman
Alignment do. type.underline (Cmd+Shift+U) underlines a mixed selection
the same way. The Character Alignment and Digits submenus check no item
while the selected characters differ.
text.setFormat ignored a value that was not true or false for underline,
strikethrough, allCaps, proportionalMetrics, tateChuYoko,
standardVerticalRoman, noBreak, hyphenate, hyphenateCapitalized and
romanHangingPunctuation. It now refuses it with "`<key>` must be true or
false" and changes nothing, as text.setRangeStyle does.
The reference app's shortcut list switches between its Type tools with
Shift and with Alt (Option). VectorCraft's Type tools had no such switch.
While no type is being edited, a press with Shift held makes new type
with the chosen tool's horizontal or vertical counterpart: Type and
Vertical Type, Area Type and Vertical Area Type, Type on a Path and
Vertical Type on a Path. A press with Alt held makes it with Type on a
Path in place of Area Type, or the reverse, in the same writing
direction. With both keys held, both switch. The keys held when the
press starts are the ones that count. The pointer shows the tool the
press acts as, and the chosen tool stays selected. While type is being
edited, Shift and Alt work as they did.
