PaneState

context (WindowContext) # – the winlink the pane was reached through

id (PaneId) # – the pane's stable id

index (int) # – the pane's position, which shifts as neighbours come and go

active (boolean) # – whether it was the active pane of its window

currentCommand (String) # – the command tmux reported running in it

size (Dimensions) # – how large the pane was, in terminal cells

position (PanePosition) # – where the pane's top-left corner sat in its window, in terminal cells

title (String) # – the pane title, which a program inside it can change

currentPath (String) # – the working directory tmux reported for it, as text. Not a java.nio.file.Path: a directory name is bytes to tmux, and converting one this JVM's encoding cannot represent throws — which, in a capture, would lose every other pane over one pane's directory. Pane.currentPath() converts on request instead

pid (OptionalLong) # – the process id of the program running in it, or empty when tmux reports no process at all — never a literal zero, so a caller cannot mistake the sentinel for a real pid

edges (PaneEdges) # – which sides of its window the pane touches

floating (Optional<Boolean>) # – whether the pane floats, or empty when the running tmux cannot say. Before 3.7 the format expands to nothing at all, and reporting that as false would be indistinguishable from a tmux that looked and found the pane was not floating.
