7selection-popup - selection management pop-up
8
9=head1 DESCRIPTION
10
11Binds a popup menu to Ctrl-Button3 that lets you paste the X
12selections and either modify or use the internal selection text in
13various ways (such as uri unescaping, perl evaluation, web-browser
14starting etc.), depending on content.
15
16Other extensions can extend this popup menu by pushing a code reference
17onto C<< @{ $term->{selection_popup_hook} } >>, which gets called whenever
18the popup is being displayed.
19
20Its sole argument is the popup menu, which can be modified. The selection
21is in C<$_>, which can be used to decide whether to add something or not.
22It should either return nothing or a string and a code reference. The
23string will be used as button text and the code reference will be called
24when the button gets activated and should transform C<$_>.
25
26The following will add an entry C<a to b> that transforms all C<a>s in
27the selection to C<b>s, but only if the selection currently contains any
28C<a>s:
29
30 push @{ $self->{term}{selection_popup_hook} }, sub {
31 /a/ ? ("a to b" => sub { s/a/b/g }
32 : ()
33 };
