Tab completion in SSH connection?

Topics: Developer Forum, User Forum

I use terminals mainly for the RDP sessions with windows. However, I would also like to use it for my SSH connections.

The problem is, TAB completion does not work. When I am in a SSH session, the TAB key does not do completion, it tabs to another section of the application. Is there a way to correct this problem?

Thanks in advance.

Anything new for this? That would really be great to have the tab completion working.

Terminals is so nice that I would like to do everything around it ! :)

Cheers !

I would love to add this as well, unfortunately I'm using a 3rd party control for the SSH connection which doesnt support this either...

For an interim fix, add the following code to class WalburySoftware.TerminalEmulator in TerminalControl/TerminalControl.cs

protected override bool ProcessDialogKey(Keys keyData)
if (keyData == Keys.Tab)
Message m = new Message();
m.Msg = WMCodes.WM_CHAR;
m.WParam = new IntPtr((int)keyData);

return true;
return base.ProcessDialogKey(keyData);

done!  Tested with Telnet and it works like a charm.

Is this already included in version 1.7b? or will it be in the next one?

Thank you so much for your work!

Also thank you Dozey!

 Thankyou.  Unfortunately I only have time chime in with these quick hacks, so here's my last improvement:

For WalburySoftware.TerminalEmulator in TerminalControl/TerminalControl.cs - The arrow / navigation keys weren't being sent

protected override bool ProcessDialogKey(Keys keyData)

Message keyMess = new Message();
keyMess.WParam = new IntPtr((int) keyData);
switch (keyData)
case Keys.Left:
case Keys.Up:
case Keys.Right:
case Keys.Down:
keyMess.Msg = 0x100;
byte[] buffer = new byte[8];
byte[] bytes = BitConverter.GetBytes((ushort) keyData);
buffer[2] = bytes[0];
buffer[3] = 1;
keyMess.LParam = new IntPtr(BitConverter.ToInt64(buffer, 0));
return true;
case Keys.Tab:
keyMess.Msg = 0x102;
return true;
return base.ProcessDialogKey(keyData);

Also, add the following to WalburySoftware.TerminalEmulator.uc_Keyboard.uc_KeyMap.SetToDefault() in TerminalControl/TerminalControl.cs - I had neither the knowledge nor time to educate myself as to which keyboard mappings were in use, so I slipped these in; seems to work over ssh. You could alternatively map the up/down/right/left keys in ProcessDialogKeys() to their predefined key codes, which are 72, 80, 77 and 75 respectively. I decided to add mappings for the codes defined in System.Windows.Forms.Keys as follows instead. 

Elements.Add(new uc_KeyInfo(38, true, "Key", "\x1B[A", uc_Mode.Any, 0));
Elements.Add(new uc_KeyInfo(40, true, "Key", "\x1B[B", uc_Mode.Any, 0));
Elements.Add(new uc_KeyInfo(39, true, "Key", "\x1B[C", uc_Mode.Any, 0));
Elements.Add(new uc_KeyInfo(37, true, "Key", "\x1B[D", uc_Mode.Any, 0));

Sorry I can't be of much assistance; I'd hand over the amended source code if I still had a copy - the changes above were pried from an assembly using Reflector and my sketchy memory. Hopefully some good will come of it.

  patch 2034 steals code from VncSharp and makes not just tab completion but arrow keys work.
