Yes, it would. Basically it allows you to do screen control and the output depends on the TERM environment variable.
We either implement a wrapper around pure terminfo which is quite low-level. You have to make calls that create output strings using the building blocks described here: http://pubs.opengroup.org/onlinepubs/7908799/xcurses/terminfo.html Or, we can interface to curses, which is a higher-level API, providing calls such as "goto position", "create window [rectanguar work area] here", etc. The benefit of curses is that it keeps track of the content of the screen, making things like repaint both optimised and simple. Ther API for curses can be found here: http://pubs.opengroup.org/onlinepubs/7908799/xcurses/curses.h.html As for implementation, creating an APL API for terminfo is obviously easier. Much less thinking involved. :-) Regards, Elias On 18 August 2014 23:27, Blake McBride <blake1...@gmail.com> wrote: > I like this!
