Window Management

Windows are managed by the user, hence the manual in manual tiling. Despite this, custard provides means of matching a window by either its name or class in order to automatically apply settings the user prescribes to the window.

When using the match command with a window class (window.class) or window name (window.name), the string is tested as a regular expression.

$ custard - match window.name 'expression' ([setting name] [setting value]...)
$ custard - match window.class 'expression' ([setting name] [setting value]...)

Setting name	Default value	Accepted inputs	Behavior
borders	0	Any positive integer	Sets the amount of borders for a matched window. Currently a maximum of three borders is supported.
border.size.inner	0	Any positive integer	Sets the inner-border size for a matched window. Unused for single-border windows
border.size.outer	0	Any positive integer	Sets the inner-border size for a matched window
border.color.focused	#FFFFFFFF	Any hexadecimal color, with or without an alpha channel	Sets the focused color for a matched window border
border.color.unfocused	#676767FF	Any hexadecimal color, with or without an alpha channel	Sets the unfocused color for a matched window border
border.color.background	#000000FF	Any hexadecimal color, with or without an alpha channel	Sets the background color for a matched window. Also used as a border background color for two or more borders
border.colors.flipped	False	Any boolean (True or False)	Flips border colors between the focus-state color and background color
geometry	Monitor default geometry	Any geometry name	Sets the geometry of a matched window
workspace	Current workspace	Any positive integer	Sets the workspace that a matched window is in by default

Example

To send Chrome to workspace 2

$ custard - match window.name 'Chrom(.+)' \
    workspace 2

To display images in a border-less window

$ custard - match window.class 'feh' \
    borders 0
