Dear Monks

I'm trying to read a range of text from Vte::Terminal

There is a very old reference of Gtk2::Vte on how to call this method at :
https://gtk2-perl.sourceforge.net/doc/pod/Gnome2/Vte/Terminal.html

And this link documents the function and its parameters
https://api.gtkd.org/vte.Terminal.Terminal.getTextRange.html

My problem is that I don't understand how to create the $func parameter

I have tried this code, but it fails with fatal errors

$$self{_GUI}{_VTE} = Vte::Terminal->new();
# more code

my $func = sub { return 1 };
my $string = $$self{_GUI}{_VTE}->get_text_range($row, $col, $row, $end
+_col, $func, my $data = undef);

[download]
ERROR:gperl-i11n-invoke-c.c:584:_allocate_out_mem: assertion failed: (interface_info)
Bail out! ERROR:gperl-i11n-invoke-c.c:584:_allocate_out_mem: assertion failed: (interface_info)

And many other variants that make even less sense, and all of them fail. Inclusive passing the undef value to the function.

For example this line does not crash, but it does not work either

my $func = {sub => {return 1}};
my $string = $$self{_GUI}{_VTE}->get_text_range($row, $col, $row, $end
+_col, $func, my $data = undef);

I need to be able to grab the text from a line where the user clicks, so I can test for the existence of a url and then try to open the url on a browser.

This is for the open source project asbru on github

If you need a working code, the only option I can offer is to clone the repo at : https://github.com/asbru-cm/asbru-cm

Edit PACTerminal.pm and around line 1141 you should see the button_press_event

In the button_press_event, you can add the line to grab the text with any fixed parameters at any point when the user clicks

Thanks
