The library is crossplatform and has both terminal-based implementations on *nix operating systems and a winapi console based implementation for windows operating systems. The basic idea is an abstraction of the greatest common subset of features available on all major terminals and other terminal-like APIs in a minimalistic fashion. Small API means it is easy to implement, test, maintain and learn it, that's what makes the termbox a distinct library in its area. - -### Installation -Install and update this go package with `go get -u github.com/nsf/termbox-go` - -### Examples -For examples of what can be done take a look at demos in the _demos directory.
