[desktop-discuss] VTE not working properly!

[Brian Cameron]

Edgar:

I took a look at the backspace key not working in VTE and the problem
seems to be in the src/vte.c file, in the function
vte_terminal_key_press.

It has some code like this:

   case VTE_ERASE_AUTO:
   default:
           if (terminal->pvt->pty_master != -1) {
                   if (tcgetattr(terminal->pvt->pty_master, &tio != -1) {
                            normal = g_strdup_printf("%c",
                                     tio.c_cc[VERASE]);
                            normal_length = 1;
                   }
           }

The problem seems to be that the tcgetattr() function is returning -1.
I notice errno is 22 (EINVAL).  This is odd since the tcgetattr() man
page doesn't indicate that this is a return code tcgetattr() will
return.  EINVAL is "Invalid argument", but the arguments look okay to
me.  Weird.

You can hack around this by changing the two calls in vte_terminal_init
to pass in VTE_ERASE_ASCII_BACSPACE instead of VTE_ERASE_AUTO.

     vte_terminal_set_backspace_binding(terminal,
         VTE_ERASE_ASCII_BACKSPACE);
     vte_terminal_set_delete_binding(terminal,
         VTE_ERASE_ASCII_BACKSPACE);

That seems a hacky workaround, though.  Anybody have any ideas why
tcgetattr() would be failing here?

This is really annoying and happens only with vte, gnome-terminal does not show this problem (althought gnome-terminal also uses libvte... I just don't understand). First I though it was a problem with my TERM setting, but hacking the code and setting VTE terminal emulation to "xterm-color" resulted in the same issue.

One last thing... in terminals I'm not able to use the end/start keys of my keyboard... what do I need to enable those? thanks in advance!
