The window's active pane

Equivalents of The window's active pane in other languages
Language	Equivalent
Python	`libtmux.Window.active_pane`
Haskell	No public Haskell equivalent is implemented; the current modules expose scalar values and version parsing.
TypeScript	`window.Window.activePane`
Rust	`window.Window.active_pane`
Go	`tmux.Window.ActivePane`
Java	`io.github.libtmux.Window.activePane`
C#	`LibTmux.Window.ActivePane`
Swift	no accessor; `Pane.isActive` is a flag on the pane, so the active one is found by filtering a listing
OCaml	No direct public OCaml equivalent is recorded for this operation.
Perl	`LibTmux::Window::active_pane` Local captured relation. Unknown membership cannot prove that no pane is active.

No equivalent is recorded in Ruby, Lua, PowerShell, Julia, Erlang, Elixir, Common Lisp, Clojure, Kotlin, Scala or F#.
