AppWindowSwitcher

macOS application aware, keyboard driven window switcher. Spoon on top of Hammerspoon.

Switches windows by focusing and raising them. All windows matching a bundelID, a list of bundleID's, an application name matchtext, or a list of application name matchtexts are switched by cycling them. Cycling applies to visible windows of currently focused space only. The spoon does not launch applications, it operates on open windows of running applications.

Example ~/.hammerspoon/init.lua configuration:

hs.loadSpoon("AppWindowSwitcher")
    -- :setLogLevel("debug") -- uncomment for console debug log
    :bindHotkeys({
        ["com.apple.Terminal"]        = {hyper, "t"},
        [{"com.apple.Safari",
          "com.google.Chrome",
          "com.kagi.kagimacOS",
          "com.microsoft.edgemac", 
          "org.mozilla.firefox"}]     = {hyper, "q"},
        ["Hammerspoon"]               = {hyper, "h"},
        [{"O", "o"}]                  = {hyper, "o"},
    })

In this example,

• hyper-t cycles all terminal windows (matching a single bundleID),
• hyper-q cycles all windows of the four browsers (matching either of the bundleIDs)
• hyper-h brings the Hammerspoon console forward (matching the application title),
• hyper-o cycles all windows whose application title starts with "O" or "o".

Windows maintain an order on the desktop, they are stacked. The cycling logic works as follows:

• If the focused window is part of the application matching a hotkey, then the last window (in terms of stacking) of the matching application(s) will be brought forward and focused.
• If the focused window is not part of the application matching a hotkey, then the first window of the matching applications will be brought forward and focused.

Methods

bindHotkeys
Signature	AppWindowSwitcher:bindHotkeys(mapping) -> self
Type	Method
Description	Binds hotkeys for AppWindowSwitcher
Parameters	mapping - A table containing hotkey modifier/key details for each application to manage
Returns	The AppWindowSwitcher object
Notes	The mapping table accepts these formats per table element: * A single text to match: ["<matchtext>"] = {mods, key} * A list of texts, to assign multiple applications to one hotkey: [{"<matchtext>", "<matchtext>", ...}] = {mods, key} * <matchtext> can be either a bundleID, or a text which is substring matched against a windows application title start.

setLogLevel
Signature	AppWindowSwitcher:setLogLevel(level) -> self
Type	Method
Description	Set the log level of the spoon logger.
Parameters	Log level - "debug" to enable console debug output
Returns	The AppWindowSwitcher object
