Windows window manipulation for node.js
winctl wraps a few functions of the windows api to allow iterating over currently opened windows and performing a few limited operations on them. This is not a production ready module! There is no real documentation either yet. Sorry for that.
The example has to suffice for now.

Requirements
This module is currently only compatible with Windows. Please ensure you have the required dependencies as well as Visual Studio installed.
Building
node-gyp is required to build xinput.js.
Install node-gyp using npm:
npm install -g node-gyp
Then configure and build:
node-gyp configure
node-gyp build
Example
var winctl = require('../'); var win = winctl.GetActiveWindow(); // Output some information about the currently active windowconsole.log("Active Window Hwnd:", win.getHwnd());console.log("Active Window Title:", win.getTitle());console.log("Dimensions:", win.dimensions());/* ->Active Window Hwnd: 26282110Active Window Title: Bash cpp-modules/winctlDimensions: { left: 708, top: 112, right: 2025, bottom: 1132 }*/ // Manipulate the currently active window a bit// Move active window to 0,0 and resize it to 800x600win.move(0, 0, 800, 600); // Move active window to the right by 30px and increase its width by 60pxwin.moveRelative(30, 0, 60, 0); // Minimize the active windowwin.showWindow(winctl.WindowStates.MINIMIZE); console.log(); // Find a windows "File Explorer" window by ClassNameconsole.log("Title of window with class 'CabinetWClass':", winctl.GetWindowByClassName("CabinetWClass").getTitle()); // Find a window by exact titleconsole.log("HWND of window with exact title 'File Explorer':", winctl.GetWindowByTitleExact("File Explorer").getHwnd()); // Find first window containing the string 'alc' and bring it to the foregroundwinctl.FindByTitle("alc").then(window => { console.log("Title of window with title 'alc':", window.getTitle()); // --> Title of window with title 'alc': Calculator // Activate the window window.setForegroundWindow();}); // Iterate over all windows with a custom filter -> show all visible windowswinctl.FindWindows(win => win.isVisible() && win.getTitle()).then(windows => { console.log("Visible windows:"); windows.sort((a,b) => a.getTitle().localeCompare(b.getTitle())).forEach(window => console.log(" - %s [pid=%d, hwnd=%d, parent=%d]", window.getTitle(), window.getPid(), window.getHwnd(), window.getParent()));});/* -->Visible windows: - Bash cpp-modules/winctl [pid=27196, hwnd=26282110, parent=NaN] - Bash cpp-modules/winctl [pid=30696, hwnd=10357510, parent=NaN] - Calculator [pid=6948, hwnd=5311194, parent=NaN] - File Explorer [pid=4860, hwnd=5115324, parent=NaN] - src [pid=4860, hwnd=219155192, parent=NaN]*/ // Log when a new window opens or the active window changeswinctl.Events.addListener("active-window", function(now, prev) { console.log("Changed active window to: %s [prev=%s]", now.getTitle(), prev.getTitle());}); winctl.Events.addListener("open-window", function(win) { console.log("Opened new window: %s [%d]", win.getTitle(), win.getHwnd());}); // Stop listening after 5ssetTimeout(() => { winctl.Events.removeAllListeners("active-window"); winctl.Events.removeAllListeners("open-window"); console.log("---done---");}, 5000);
