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