Functions

apply

Signature hs.layout.apply(table[, windowTitleComparator])
Type Function
Description Applies a layout to applications/windows
Parameters
  • 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
Returns
  • None
Notes
  • 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()`. 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
