Struct Editor 

pub struct Editor { /* private fields */ }

The editor state machine. Ties together buffer, selection, and history. This is the primary public API for kode-core.

Implementations

impl Editor

pub fn new(text: &str) -> Self

Create an editor with the given text.

pub fn empty() -> Self

Create an empty editor.

pub fn buffer(&self) -> &Buffer

pub fn text(&self) -> String

pub fn selection(&self) -> Selection

pub fn cursor(&self) -> Position

pub fn version(&self) -> u64

pub fn is_dirty(&self) -> bool

pub fn can_undo(&self) -> bool

pub fn can_redo(&self) -> bool

pub fn mark_clean(&mut self)

pub fn selected_text(&self) -> String

Get the selected text, or empty string if cursor only.

pub fn insert(&mut self, text: &str)

Insert text at the cursor. If there’s a selection, replace it.

pub fn backspace(&mut self)

Delete the character before the cursor (backspace).

pub fn delete_forward(&mut self)

Delete the character after the cursor (forward delete).

pub fn delete_selection(&mut self)

Delete the current selection. No-op if cursor only.

pub fn insert_newline(&mut self)

Insert a newline at the cursor.

pub fn apply_transaction(&mut self, tx: Transaction)

Apply a pre-built transaction atomically. All steps are applied and a single history entry is created for undo.

Steps must contain sequential offsets: each step’s offset is relative to the buffer state after all previous steps have been applied.

pub fn set_cursor(&mut self, pos: Position)

Set the cursor to a position, collapsing any selection.

pub fn set_selection(&mut self, anchor: Position, head: Position)

Set a selection range.

pub fn extend_selection(&mut self, head: Position)

Extend the selection to a new head position (shift+arrow behavior).

pub fn select_all(&mut self)

Select all text.

pub fn move_left(&mut self)

Move cursor left by one character.

pub fn move_right(&mut self)

Move cursor right by one character.

pub fn move_up(&mut self)

Move cursor up by one line.

pub fn move_down(&mut self)

Move cursor down by one line.

pub fn move_to_line_start(&mut self)

Move cursor to start of current line.

pub fn move_to_line_end(&mut self)

Move cursor to end of current line.

pub fn move_to_start(&mut self)

Move cursor to start of document.

pub fn move_to_end(&mut self)

Move cursor to end of document.

pub fn move_word_left(&mut self)

Move cursor left to the start of the previous word.

pub fn move_word_right(&mut self)

Move cursor right to the end of the next word.

pub fn extend_selection_left(&mut self)

Extend selection one character left (Shift+Left).

pub fn extend_selection_right(&mut self)

Extend selection one character right (Shift+Right).

pub fn extend_selection_up(&mut self)

Extend selection up one line (Shift+Up).

pub fn extend_selection_down(&mut self)

Extend selection down one line (Shift+Down).

pub fn extend_selection_word_left(&mut self)

Extend selection to word boundary left (Shift+Ctrl+Left).

pub fn extend_selection_word_right(&mut self)

Extend selection to word boundary right (Shift+Ctrl+Right).

pub fn extend_selection_to_line_start(&mut self)

Extend selection to line start (Shift+Home).

pub fn extend_selection_to_line_end(&mut self)

Extend selection to line end (Shift+End).

pub fn extend_selection_to_start(&mut self)

Extend selection to document start (Ctrl+Shift+Home).

pub fn extend_selection_to_end(&mut self)

Extend selection to document end (Ctrl+Shift+End).

pub fn page_up(&mut self, page_lines: usize)

Move cursor up by N lines (PageUp).

pub fn page_down(&mut self, page_lines: usize)

Move cursor down by N lines (PageDown).

pub fn select_word(&mut self)

Select the word at the cursor (double-click behavior).

pub fn select_line(&mut self)

Select the entire current line (triple-click behavior).

pub fn delete_word_back(&mut self)

Delete from cursor to start of previous word (Ctrl+Backspace).

pub fn delete_word_forward(&mut self)

Delete from cursor to end of next word (Ctrl+Delete).

pub fn indent(&mut self)

Insert a tab (2 spaces) at the cursor, or indent all selected lines.

pub fn outdent(&mut self)

Remove one level of indentation (2 spaces) from the current or selected lines.

pub fn duplicate_lines(&mut self)

Duplicate the current line or all selected lines (Ctrl+D).

pub fn word_start_before_cursor(&self) -> Position

Get the position at the start of the word before/at the cursor. Used by the autocomplete system to determine the prefix to replace.

pub fn undo(&mut self)

Undo the last transaction.

pub fn redo(&mut self)

Redo the last undone transaction.
