Controller commands the host engine implements. hjkl-vim never mutates the editor directly — it emits a command and the host (apps/hjkl) calls the corresponding Editor method.

Variants

ReplaceChar

Fields

ch: char

count: usize

FindChar

Emitted by PendingState::Find when the user completes f<x> / F<x> / t<x> / T<x>. The host calls Editor::find_char.

Fields

ch: char

forward: bool

till: bool

count: usize

AfterGChord

Emitted by PendingState::AfterG when the user completes g<x>. The host calls Editor::after_g(ch, count).

Fields

ch: char

count: usize

AfterZChord

Emitted by PendingState::AfterZ when the user completes z<x>. The host calls Editor::after_z(ch, count).

Fields

ch: char

count: usize

ApplyOpMotion

d<motion> / y<motion> / c<motion> / ><motion> / <<motion> — apply operator over a single-key motion. motion_key is the raw key char (e.g. 'w', '$', 'G'). Engine parses via parse_motion and applies. total_count = count1 * inner_count.

Fields

op: OperatorKind

motion_key: char

total_count: usize

ApplyOpDouble

dd / yy / cc / >> / << — doubled-letter line op.

Fields

op: OperatorKind

total_count: usize

ApplyOpTextObj

diw etc. — apply operator over text-object range. The reducer owns the i/a key via PendingState::OpTextObj; on the next char it emits this command. Host calls Editor::apply_op_text_obj.

Fields

op: OperatorKind

ch: char

inner: bool

total_count: usize

ApplyOpG

dgg etc. — apply operator over g-chord motion or case-op linewise form. The reducer owns the g key via PendingState::OpG; on the next char it emits this command. Host calls Editor::apply_op_g.

Fields

op: OperatorKind

ch: char

total_count: usize

ApplyOpFind

df<x> / dF<x> / dt<x> / dT<x> — apply operator over find motion. Engine builds Motion::Find { ch, forward, till } and applies it. total_count is count1 * inner_count folded at transition time.

Replaces EnterOpFind (removed in 0.7.0). The reducer no longer sets engine Pending::OpFind; instead it transitions to PendingState::OpFind and emits this command on the next char.

Fields

op: OperatorKind

ch: char

forward: bool

till: bool

total_count: usize

SetPendingRegister

"<reg> chord completion. Engine validates reg against [a-zA-Z0-9"+*_] and sets vim.pending_register if valid. Invalid chars are silently ignored (no-op), matching the engine FSM behaviour.

Fields

reg: char

SetMark

m<ch> chord completion. Engine validates ch and records the mark at the current cursor position. Invalid chars are silently ignored (no-op).

Fields

ch: char

GotoMarkLine

'<ch> chord completion. Engine validates ch and jumps to the mark linewise (row only, cursor lands on first non-blank column). Invalid or unset marks are silently ignored (no-op).

Fields

ch: char

GotoMarkChar

`<ch> chord completion. Engine validates ch and jumps to the mark charwise (exact row + col). Invalid or unset marks are silently ignored (no-op).

Fields

ch: char

Trait Implementations

impl Clone for EngineCmd

fn clone(&self) -> EngineCmd

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineCmd

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

Formats the value using the given formatter.

impl PartialEq for EngineCmd

fn eq(&self, other: &EngineCmd) -> 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.
