Applies a layout to applications/windows

• table - A table describing your desired layout. Each element in the table should be another table describing a set of windows to match, and their desired size/position. The fields in each of these tables are:
  • A string containing an application name, or an hs.application object, or nil
  • A string containing a window title, or an hs.window object, or a function, or nil
  • A string containing a screen name, or an hs.screen object, or a function that accepts no parameters and returns an hs.screen object, or nil to select the first available screen
  • A Unit rect, or a function which is called for each window and returns a unit rect (see hs.window.moveToUnit()). The function should accept one parameter, which is the window object.
  • A Frame rect, or a function which is called for each window and returns a frame rect (see hs.screen:frame()). The function should accept one parameter, which is the window object.
  • A Full-frame rect, of a function which is called for each window and returns a full-frame rect (see hs.screen:fullFrame()). The function should accept one parameter, which is the window object.
• windowTitleComparator - (optional) Function to use for window title comparison. It is called with two string arguments (below) and its return value is evaluated as a boolean. If no comparator is provided, the '==' operator is used
  • windowTitle: The :title() of the window object being examined
  • layoutWindowTitle: The window title string (second field) specified in each element of the layout table
  • Optionally a final element, the key "options" and a table value that can contain the following keys: * absolute_x: A boolean indicating that the x value in a frame rect above, is an absolute co-ordinate (ie useful for negative absolute co-ordinates) * absolute_y: A boolean indicating that the y value in a frame rect above, is an absolute co-ordinate (ie useful for negative absolute co-ordinates)

• None

• If the application name argument is nil, window titles will be matched regardless of which app they belong to

• If the window title argument is nil, all windows of the specified application will be matched

• If the window title argument is a function, the function will be called with the application name argument (which may be nil), and should return a table of hs.window objects (even if there is only one window it must be in a table)

• You can specify both application name and window title if you want to match only one window of a particular application

• If you specify neither application name or window title, no windows will be matched :)

• Monitor name is a string, as found in hs.screen:name() or hs.screen:getUUID(). You can also pass an hs.screen object, or a function that returns an hs.screen object. If you pass nil, the first screen will be selected

• The final three arguments use hs.geometry.rect() objects to describe the desired position and size of matched windows:

  • Unit rect will be passed to hs.window.moveToUnit()
  • Frame rect will be passed to hs.window.setFrame() (including menubar and dock)
  • Full-frame rect will be passed to hs.window.setFrame() (ignoring menubar and dock)

• If either the x or y components of frame/full-frame rect are negative, they will be applied as offsets against the opposite edge of the screen (e.g. If x is -100 then the left edge of the window will be 100 pixels from the right edge of the screen)

• Only one of the rect arguments will apply to any matched windows. If you specify more than one, the first will win

• An example usage:

  layout1 = {
      {"Mail", nil, "Color LCD", hs.layout.maximized, nil, nil},
      {"Safari", nil, "Thunderbolt Display", hs.layout.maximized, nil, nil},
      {"iTunes", "iTunes", "Color LCD", hs.layout.maximized, nil, nil},
      {"iTunes", "MiniPlayer", "Color LCD", nil, nil, hs.geometry.rect(0, -48, 400, 48)},
    }```
  

• An example of a function that works well as a windowTitleComparator is the Lua built-in string.match, which uses Lua Patterns to match strings
