=head1 DESCRIPTION |
28
|
|
|
|
|
|
|
|
29
|
|
|
|
|
|
|
rofi is a lightweight, extensible, scriptable, menu interface for Linux. It has |
30
|
|
|
|
|
|
|
a scripting API documented in C. This module is a perl |
31
|
|
|
|
|
|
|
interface to that API. |
32
|
|
|
|
|
|
|
|
33
|
|
|
|
|
|
|
Generally, the interface works by L to STDOUT, |
34
|
|
|
|
|
|
|
which appear in the rofi menu for selection. Each time a user selects an option, |
35
|
|
|
|
|
|
|
the script is called again with the most recent selection pushed onto C<@ARGV>. |
36
|
|
|
|
|
|
|
|
37
|
|
|
|
|
|
|
There are also some envars that let you inspect certain user actions. Those are |
38
|
|
|
|
|
|
|
exposed via: |

There are also some options that can be set by printing specially formatted |

|
|
|
|
|
|
|
strings to STDOUT. |

This is a god object that's the primary interface to the entire script |

various methods and configuration options. |

If it doesn't look like the script was called by rofi (i.e. C is |
119
|
|
|
|
|
|
|
unset), I C is unset, this will return undef. So it's |
120
|
|
|
|
|
|
|
possible to know if your script (or whatever) was called from rofi or not. |
