Built-ins
=========
Types:
- "string": A string.
- 1, 2, 3: Integers
- #t, #f: Booleans.
Boolean operations:
- (and bool*) -> bool: perform a boolean AND of boolean values
- (or bool*) -> bool: perform a boolean OR of boolean values
Addition, substraction:
- (+ int*) -> int: add integers
- (+ string*) -> string: concat strings
- (- int int*) -> int: subtract integers from the first
Types casting:
- (cast-int string|int|bool) -> int: cast to an integer value
- (cast-string string|int|bool) -> string: cast to an string value
Comparison operators:
- (<|>|= int int) -> bool: compare two integers
- (<|>|= string string) -> bool: compare two strings
Function flow:
- (if bool func) -> type: execute a function if the condition holds
- (if bool func func) -> type: choose what function to execute depending on the
condition
- (begin func func*) -> type: execute a sequence of functions, and return the
result of the last one
Logical operations
==================
This are predicates you can use to test strings, for instance in "if"
conditions.
- (is string string) -> bool: return #t if the two strings are the same
Example: (if (is (application_name) "XMMS") ...)
- (contains string string) -> bool: return #t if the second string is a
substring of the first one.
Example: (if (contains (application_name) "term") ...)
- (matches string string) -> bool: return #t if the second string is a regular
expression matching the first one.
Example: (if (matches (window_name) "^Character.+") ...)
Matchers
========
Matchers are functions which return informations about windows. You can for
instance use them in "if" condition to match some particular windows.
- (window_name) -> string: return the title of the current window
- (application_name) -> string: return the application name of the current
window, as determined by libwnck
- (window_role) -> string: return the role of the current window, as determined
by the WM_WINDOW_ROLE hint
- (window_class) -> string: return the class of the current window
Actions
=======
Actions are the functions you can use to change some window properties.
All actions return booleans (TRUE on success, FALSE on failure).
- (debug): debugging function - print informations about current window
- (print args*): print all arguments
- (geometry string): set size and/or position of a window. Examples:
(if ... (geometry "600x600"))
(if ... (geometry "+200+200"))
(if ... (geometry "600x600+200+200"))
- (fullscreen): make the current window fullscreen
- (focus): focus the current window
- (center): center position of current window
- (maximize): maximize the current window
- (maximize_vertically): maximize the current window vertically
- (maximize_horizontally): maximize the current window horizontally
- (minimize): minimize the current window
- (shade): shade ("roll up") the current window
- (unshade): unshade ("roll down") the current window
- (close): close the current window
- (pin): pin the current window to all workspaces
- (unpin): unpin the current window from all workspaces
- (set_workspace int): move the window to a specific workspace number,
counting from 1
- (skip_pager): remove the current window from the pager
- (skip_tasklist): remove the current window from the window list
- (above): set the current window to be above all normal windows
- (below): set the current window to be below all normal windows
- (undecorate): remove the window manager decorations from the current window
- (wintype string): set the window type of the current window. Accepted values
are: "normal", "dialog", "menu", "toolbar", "splashscreen", "utility",
"dock" and "desktop".
