Layout and visual settings for the editor canvas.

Fields

line_numbers: bool

Whether to render line numbers in the left gutter.

line_height: Pixels

Vertical line height in pixels.

font_size: Pixels

Text font size in pixels.

tab_size: usize

Number of spaces per tab indentation.

highlight_active_line: bool

Whether to highlight the background of the active cursor line.

block_cursor: bool

Default cursor shape: true for block, false for line/bar.

cursor_blink: bool

Whether the cursor should blink when focused.

context_menu: bool

Whether right-click opens the expandable context menu.

show_default_menu_items: bool

Whether the built-in edit rows (Undo/Redo/Cut/Copy/Paste/Delete/Select All) lead the context menu. Hooks always append after them.

line_wrap: bool

Whether to soft-wrap lines at the viewport boundary.

font_family: Option<SharedString>

Base font family override (None auto-selects, see below).

When unset, the editor probes Self::platform_monospace_candidates at paint time and uses the first family with bold + italic faces. An explicitly set family is trusted verbatim (still probed, so Editor::face_availability stays truthful). Missing faces fall back silently at the OS level, which is why auto-select exists.

code_font_family: Option<SharedString>

Font family for Code spans (None reuses the base family).

markdown: MarkdownConfig

Markdown WYSIWYG and syntax configuration.

Implementations

impl EditorConfig

pub fn platform_monospace_candidates() -> Vec<SharedString>

Ordered monospace fallback families for font auto-select.

Ordered by likelihood of shipping full (regular/bold/italic/bold-italic) faces: a partial set (e.g. regular+bold only) can never satisfy emphasis, so completeness outranks name recognition.

pub fn font_candidates(&self) -> Vec<SharedString>

Candidate families for auto-select: the explicit family alone when set, otherwise the platform list.

pub fn pick_family( candidates: &[SharedString], probe: impl FnMut(&str) -> (bool, bool), ) -> Option<&SharedString>

Picks the first candidate with bold + italic faces (else the first with either, else None). Pure to stay headless-testable; callers pass a probe comparing resolved FontIds.

pub fn base_font(&self, host: &Font, selected: Option<&SharedString>) -> Font

Resolves the base font: explicit family, else auto-selected family, else host.

pub fn code_font(&self, host: &Font, selected: Option<&SharedString>) -> Font

Resolves the font for Code spans: explicit code family, else whatever Self::base_font resolves (so code follows auto-select by default).

Trait Implementations

impl Clone for EditorConfig

fn clone(&self) -> EditorConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EditorConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EditorConfig

fn default() -> Self

Returns the “default value” for a type.
