Also, it is -important to mention that a main loop iteration is executed on each reported -event (key-press, mouse event, window resize, etc). - -GUIs are composed by Views, you can think of it as buffers.

The reason for this is that it allows gocui to be -concurrent-safe. So, if you want to update your GUI from a goroutine, you must -use *Gui.Update().

But I'm glad that it did what I wanted the most. It moved people away from "ncurses" mindset and these days we see both re-implementations of termbox API in various languages and even possibly better libs with similar API design. If you're looking for a Go lib that provides terminal-based user interface facilities, I've heard that https://github.com/gdamore/tcell is good (never used it myself). Also for more complicated interfaces and/or computer games I recommend you to consider using HTML-based UI. Having said that, termbox still somewhat works. In fact I'm writing this line of text right now in godit (which is a text editor written using termbox-go). So, be aware. Good luck and have a nice day. + +## Termbox +Termbox is a library that provides a minimalistic API which allows the programmer to write text-based user interfaces. 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.

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.
