Implementations

impl MarkdownSpanner

pub fn render_with<'a>( content: &'a str, logical_line: &'a str, parsed: &'a ParsedLine, visual_start_col: usize, cursor_col: Option<usize>, is_first_visual_line: bool, force_raw: bool, available_width: u16, theme: &Theme, ) -> Vec<Span<'a>>

pub fn rendered_cursor_col_with( logical_line: &str, parsed: &ParsedLine, visual_start_col: usize, cursor_col: usize, is_first_visual_line: bool, force_raw: bool, ) -> usize

Rendered screen column for cursor_col, treating that same column as the caret — so the markdown element it lands in counts as revealed.

Correct for mapping the real caret. To map an arbitrary column (a selection edge, a replace preview span boundary) use Self::rendered_col_with_reveal and pass the caret separately: otherwise the mapper reveals whatever element the boundary touches, counts that element’s hidden sigils as drawn, and the highlight lands right of the text it belongs to.

pub fn rendered_col_with_reveal( logical_line: &str, parsed: &ParsedLine, visual_start_col: usize, cursor_col: usize, reveal_col: Option<usize>, is_first_visual_line: bool, force_raw: bool, ) -> usize

Rendered screen column for target_col, with element reveal driven by reveal_col — the row’s real caret column, or None when the caret is on another row.

The split matters because render_with reveals only the element under the caret. Any mapping that assumed the measured column was the caret would disagree with what was actually drawn.

pub fn visible_positions_with( logical_line: &str, parsed: &ParsedLine, cursor_col: Option<usize>, force_raw: bool, ) -> Vec<bool>

pub fn rendered_col_to_logical_with( logical_line: &str, parsed: &ParsedLine, visual_start_col: usize, rendered_col: usize, reveal_col: Option<usize>, is_first_visual_line: bool, force_raw: bool, ) -> usize

Logical column for the cell at rendered_col, inverse of Self::rendered_col_with_reveal.

reveal_col is the row’s real caret column, or None when the caret is on another row — the same value the render loop passes as cursor_col. It has to be threaded here because render_with reveals the element under the caret, and a revealed element’s sigils occupy cells: measuring the row as if nothing were revealed put every column past the first revealed sigil out by the width of what was wrongly skipped.
