A style captured from text left out the attributes that the text's JSON skips at their defaults, such as the Hyphenation options, the Composer, tab stops, Auto kerning and the character alignment. Redefining a paragraph or character style from text set back to the defaults therefore did not reach the text using the style: a paragraph that had the old Hyphen Limit or Single-line Composer from the style kept it. setAttrs dropped a default value it was given in the same way. New and Redefine now capture every attribute of the selected text, and charStyle.setAttrs and paraStyle.setAttrs keep a default value. When a style changes, text whose value equals the old definition's takes the new value, a default included. Local overrides on text that uses a style other than the Normal styles stay, and an attribute that setAttrs leaves out still leaves the text's value alone. The Character Styles and Paragraph Styles panels compare the attributes a style holds with the same attributes of the selection. A paragraph style made from type with Auto alignment no longer shows "+" on that type. Two existing behaviors change. Applying a style made with New or Redefine from text, without Clear Overrides, now also sets the attributes that text had at their defaults, such as Auto kerning, no OpenType features, the Every-line Composer, no tab stops and the default Hyphenation options. Redefining [Normal Paragraph Style] or [Normal Character Style] from text gives every paragraph or run that uses it those attributes too, so local values of them on that text are reset.

//! Character Styles and Paragraph Styles panels.
|
|
//!
|
|
//! A style is a named, partial set of attributes ([`TextStyleDef`]); text using it records the
|
|
//! name in `CharStyle::style_name` / `ParaStyle::style_name`. Applying a style sets its attributes
|
|
//! (Clear Overrides first resets to the Normal style). Redefining a style updates its users but keeps
|
|
//! their local overrides: an attribute changes only where it still had the old style's value.
