The session's active window

Equivalents of The session's active window in other languages
Language	Equivalent
Python	`libtmux.Session.active_window`
Haskell	No public Haskell equivalent is implemented; the current modules expose scalar values and version parsing.
TypeScript	`session.Session.activeWindow`
Rust	`session.Session.active_window`
Go	`tmux.Session.ActiveWindow`
Java	`io.github.libtmux.Session.activeWindow`
C#	`LibTmux.Session.ActiveWindow`
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	Select the active captured WindowLink, then resolve its physical window.

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