Terminal is the main terminal app for GNUstep Desktop but also great way to make a command line utility into nice GNUstep app.
Terminal's code originally comes from NEXTSPACE's Terminal.app, which in turn comes from GAP project created by Alexander Malmberg.
It makes it really easy to embed terminal application in a GNUstep app or create a wrapper (e.g. see VimGS as an example). This approach is used by many GNUstep Desktop apps.
The mouse support is compatible with XTerm
- mouse tracking
- mouse scroll wheel
Great for vim!
Send commands back to your GNUstep wrapper.
The wrapped program can print special escape sequence in form of ^[]X;<CMD>^G
where <CMD> is a string.
This will cause - (void)ts_handleXOSC:(NSString *)cmd to be called on your TerminalView.
Similar approach can be used to communicate the other way around where GNUstep wrapper sends an escape code (either real or made up) to trigger functionality in the wrapped program.
Good example how this could works in practice is VimGS project, vimrc file in particular.
Although Terminal is originally based on Linux console terminal, it now includes support for codes used by Xterm and other terminals.
To make sure command line tools knows about all of its functions, Terminal comes with its own terminfo file which needs to be installed for things to work properly.
You can then refer to it as TERM=gsterm
Terminal supports StepTalk support.
