Text editing commands

Variants

Insert

Insert text at the specified position

Fields

offset: usize

Character offset to insert at.

text: String

Text to insert.

Delete

Delete text in specified range

Fields

start: usize

Character offset of the deletion start.

length: usize

Length of the deletion in characters.

Replace

Replace text in specified range

Fields

start: usize

Character offset of the replacement start.

length: usize

Length of the replaced range in characters.

text: String

Replacement text.

InsertText

VSCode-like typing/paste: apply to all carets/selections (primary + secondary)

Fields

text: String

Text to insert/replace at each selection/caret.

InsertTab

Insert a tab at each caret (or replace each selection), using the current tab settings.

• If TabKeyBehavior::Tab, inserts '\t'.
• If TabKeyBehavior::Spaces, inserts spaces up to the next tab stop.

InsertNewline

Insert a newline at each caret (or replace each selection).

If auto_indent is true, the inserted newline is followed by the leading whitespace prefix of the current logical line.

Fields

auto_indent: bool

Whether to auto-indent the new line.

Indent

Indent the selected lines (or the current line for an empty selection).

Outdent

Outdent the selected lines (or the current line for an empty selection).

DeleteToPrevTabStop

Smart backspace: if the caret is in leading whitespace, delete back to the previous tab stop.

Otherwise, behaves like EditCommand::Backspace.

DeleteGraphemeBack

Delete the previous Unicode grapheme cluster (UAX #29) for each caret/selection.

DeleteGraphemeForward

Delete the next Unicode grapheme cluster (UAX #29) for each caret/selection.

DeleteWordBack

Delete back to the previous Unicode word boundary (UAX #29) for each caret/selection.

DeleteWordForward

Delete forward to the next Unicode word boundary (UAX #29) for each caret/selection.

Backspace

Backspace-like deletion: delete selection(s) if any, otherwise delete 1 char before each caret.

DeleteForward

Delete key-like deletion: delete selection(s) if any, otherwise delete 1 char after each caret.

Undo

Undo last edit operation (supports grouping)

Redo

Redo last undone operation (supports grouping)

EndUndoGroup

Explicitly end the current undo group (for idle or external boundaries)

ReplaceCurrent

Replace the current occurrence of query (based on selection/caret) with replacement.

• Honors options (case sensitivity / whole-word / regex).
• Treated as a single undoable edit.

Fields

query: String

Search query.

replacement: String

Replacement text.

options: SearchOptions

Search options (case sensitivity, whole-word, regex).

ReplaceAll

Replace all occurrences of query with replacement.

• Honors options (case sensitivity / whole-word / regex).
• Treated as a single undoable edit.

Fields

query: String

Search query.

replacement: String

Replacement text.

options: SearchOptions

Search options (case sensitivity, whole-word, regex).

Trait Implementations

impl Clone for EditCommand

fn clone(&self) -> EditCommand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EditCommand

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

Formats the value using the given formatter.

impl PartialEq for EditCommand

fn eq(&self, other: &EditCommand) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
