Functions

func FindClosestSlot 

func FindClosestSlot(x, y int, state *State) int

FindClosestSlot finds the slot index whose position is closest to the given point. Used when entering grabbed mode to start at the current window's slot.

func FindTerminalAtSlot 

func FindTerminalAtSlot(slotIdx int, state *State) int

FindTerminalAtSlot returns the index of the terminal at the given slot, or -1 if empty. 

func NavigateSlot(currentIdx int, dir Direction, rows, cols int) int

NavigateSlot calculates the new slot index after moving in a direction. Uses spatial navigation: arrow keys move in the grid based on direction. Wraps around at edges. NOTE: This assumes a uniform grid. For layouts with variable columns per row (like flexible_last_row), use NavigateSlotSpatial instead. 

func NavigateSlotSpatial(currentIdx int, dir Direction, positions []tiling.Rect, rows, cols int) int

NavigateSlotSpatial navigates slots using actual slot positions. This handles layouts with variable columns per row (like flexible_last_row). Falls back to grid math if positions is empty. 

func NavigateTerminal(currentIdx int, dir Direction, count int) int

NavigateTerminal cycles through terminals in a list. For PhaseSelecting: cycles through available terminals. Wraps around at edges.

Types

type Action 

type Action int

Action represents a terminal action from move mode. 

const (
	// ActionNone means no action is pending.
	ActionNone Action = iota
	// ActionDeleteSelected removes the selected slot (requires confirmation).
	ActionDeleteSelected
	// ActionInsertAfterSelected inserts a terminal after the selected slot.
	ActionInsertAfterSelected
	// ActionAppend appends a terminal at the end.
	ActionAppend
)

func (Action) String 

func (a Action) String() string

String returns a readable action name.

type BorderOverlay 

type BorderOverlay struct {
	Top    xproto.Window
	Bottom xproto.Window
	Left   xproto.Window
	Right  xproto.Window
	// contains filtered or unexported fields
}

BorderOverlay represents a rectangular border made of 4 thin windows

type Direction 

type Direction int

Direction represents an arrow key direction 

const (
	DirUp Direction = iota
	DirDown

const (
	HintPhaseNone HintPhase = iota
	HintPhaseSelecting
	HintPhaseMove
	HintPhaseConfirmDelete
)

type LayoutProvider 

type LayoutProvider interface {
	GetActiveLayoutName() string
}

type Mode 

type Mode struct {

	// OnMoveComplete is called after a successful move/swap operation.
	OnMoveComplete OnMoveCompleteFunc
	// contains filtered or unexported fields
}

Mode is the main move mode controller

func NewMode 

func NewMode(backend platform.Backend, detector *terminals.Detector, cfg *config.Config, layoutProvider LayoutProvider) *Mode

NewMode creates a new move mode controller

func (*Mode) Enter 

func (m *Mode) Enter() error

Enter activates move mode, starting in the selecting phase

func (*Mode) Exit 

func (m *Mode) Exit()

Exit deactivates move mode

func (*Mode) HandleArrowKey 

func (m *Mode) HandleArrowKey(dir Direction)

HandleArrowKey processes an arrow key press

func (*Mode) HandleCancel 

func (m *Mode) HandleCancel()

HandleCancel processes the Escape key press

func (*Mode) HandleConfirm 

func (m *Mode) HandleConfirm()

HandleConfirm processes the Enter key press

func (*Mode) IsActive 

func (m *Mode) IsActive() bool

IsActive returns true if move mode is currently active

func (*Mode) UpdateConfig 

func (m *Mode) UpdateConfig(cfg *config.Config)

UpdateConfig updates the mode's configuration reference

type MoveResult 

type MoveResult struct {
	// SourceSlot is the original slot index of the moved window.
	SourceSlot int
	// TargetSlot is the new slot index of the moved window.
	TargetSlot int
	// IsSwap indicates whether two windows were swapped.
	IsSwap bool
}

MoveResult contains information about a completed move operation.

type OnMoveCompleteFunc 

type OnMoveCompleteFunc func(result MoveResult)

OnMoveCompleteFunc is called after a move operation completes. It receives the move result for post-processing (e.g., renaming tmux sessions).

type OverlayManager 

type OverlayManager struct {
	// contains filtered or unexported fields
}

OverlayManager manages overlay windows for move mode

func NewOverlayManager 

func NewOverlayManager(xu *xgbutil.XUtil, root xproto.Window) *OverlayManager

NewOverlayManager creates a new overlay manager

func (*OverlayManager) Cleanup 

func (m *OverlayManager) Cleanup()

Cleanup destroys all overlay windows

func (*OverlayManager) HideAll 

func (m *OverlayManager) HideAll()

Render draws borders for all terminals and all grid slots.

Slots are rendered first and terminals after, so terminal borders appear on top.

type Phase 

type Phase int

Phase represents the current phase of move mode 

const (
	// PhaseInactive means move mode is not active
	PhaseInactive Phase = iota
	// PhaseSelecting means user is choosing which window to move

	PhaseGrabbed
	// PhaseConfirmDelete means user must confirm terminal deletion
	PhaseConfirmDelete

func (Phase) String 

func (p Phase) String() string

String returns the string representation of the phase

type State 

type State struct {
	Phase           Phase
	SelectedIndex   int               // Index of highlighted terminal in Terminals slice
	GrabbedWindow   platform.WindowID // Window ID of grabbed window (0 if none)
	TargetSlotIndex int               // Target slot index for grabbed window
	PendingAction   Action            // Pending action awaiting confirmation
	PendingSlot     int               // Slot index targeted by the pending action (-1 if none)
