Whether this was the active window when captured

Equivalents of Whether this was the active window when captured in other languages
Language	Equivalent
Python	`libtmux.Window.window_active`
Ruby	`LibTmux::WindowLinkSnapshot#active?`
Elixir	`LibTmux.WindowLink.active` The flag belongs to the session placement, `WindowLink`.
Haskell	No public Haskell equivalent is implemented; the current modules expose scalar values and version parsing.
TypeScript	no accessor; the field is read from `Window.format`, tmux's own row
Rust	`window.Window.is_active`
Go	`tmux.Window.Active`
Java	`io.github.libtmux.Window.active`
C#	no equivalent on `Window`
Swift	no equivalent on `Window`
OCaml	`Libtmux.Window_link.is_current`
Perl	`LibTmux::WindowLink::active` Captured session-relative placement data; this is not a property of the physical window.

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