Struct Capabilities

    pub bold: bool,

}

Which formatting controls this document’s format can spell — the toolbar’s enabled state, one flag per button, from LeafDoc::capabilities. Mirrors leaf_core::Capabilities, where the reasoning lives.

Its shape is a flat record of Bools rather than a query taking a gesture because the Swift side wants exactly one crossing and a value it can hold in an @Observable: let caps = doc.capabilities(), then .disabled(!caps.bold) on each control.

Fields

bold: bool

italic: bool

code: bool

mark: bool

underline: bool

strike: bool

superscript: bool

subscript: bool

heading: bool

Both LeafDoc::set_heading and LeafDoc::set_paragraph — they are the same gesture in core and stand or fall together.

blockquote: bool

bullet_list: bool

ordered_list: bool

task: bool

LeafDoc::toggle_task_item, LeafDoc::toggle_task_checked and LeafDoc::toggle_task_at — including a tap on a rendered checkbox, which should not be live where the box cannot be spelled.

link: bool

image: bool

[LeafDoc::insert_image] and LeafDoc::insert_media both.

thematic_break: bool

footnote: bool

LeafDoc::insert_footnote. Markdown and djot spell the pair; HTML does not, so the button goes rather than dims into a refusal.

code_language: bool

table: bool

The grid controls. Gate them on this and LeafDoc::caret_in_table: this asks whether the format’s tables are editable, that whether the caret is in one.

cell_line_break: bool

Shift+Return inside a cell — LeafDoc::cell_line_break.
