ruler
ruler is a program used for creating rules like in some window managers, like i3 or bspwm.
Rules are commands that are associated with a set of window properties
(descriptors). When a
window is created, ruler executes all rules whose descriptors match the properties of a
window.
Descriptors can be defined as regular expressions (POSIX Extended Regular Expressions) to avoid code repetition.
Commands are executed asynchronously by default. If a command is prefixed with a semicolon, it will be run synchronously.
For more information, see the included manual page (ruler(1)).
Example configuration
# move all browsers to workspace 2
role="browser"
wtf "$RULER_ID" && waitron group_add_window 2
# drop a notification if a window containing that fifth glyph is born
instance=".*e.*"
echo "warning!" > /tmp/notifyd.fifo
Dependencies
Build time dependencies:
- a yacc implementation (GNU bison, OpenBSD yacc etc.)
- a lex implementation (flex)
Building and installing
$ make
# make install
The Makefile respects the DESTDIR and PREFIX environment variables.
