gocui - Minimalist Go package aimed at creating Console User Interfaces

[Roi Martin]

Hi!

I've just released gocui, a minimalist Go package aimed at creating Console User Interfaces, based on termbox-go. You can find it at:

https://github.com/jroimartin/gocui

On-line doc: http://godoc.org/github.com/jroimartin/gocui

The main features of gocui are:
* Minimalist API.
* Views (the "windows" in the GUI) implement the interface io.Writer.
* Support for overlapping views.
* The GUI can be modified at runtime.
* Global and view-level keybindings.

A few examples can be found in the folder _demos (demo2.go is the more complete one).

Of course, comments are welcome. Thanks! :)

Best regards,

Roi Martin

Very cool! I've done a couple of things on top of termbox-go, which is
a great library, but I was wondering to what extent a set widgets on
top of termbox would appear over time.

Thank you Roi for writing this, it looks really good. 

I've been experimenting with termbox-go myself lately, and I have a question for you and anyone else who is using termbox-go:

Is it feasible to use termbox-go to control multiple terminals from the same process? My hope is to have a single Go process that terminal users on a particular machine somehow attach to, so I can avoid having to do any kind of serialization over a socket layer and can just used shared memory to coordinate the terminals. This seems like an approach particularly well-suited for Go, but I don't have any experience with using libraries like ncurses, etc for detailed terminal control, and I haven't found a working example yet that seems adaptable to my needs. 

Any advice here would be greatly appreciated (even including someone telling me they think this is a bad idea and I should just use sockets).

Hi John,

nsf please correct me if I am wrong, but the termbox-go's API only gives you control over the current terminal screen. On the other hand, regarding the design you are proposing, IMHO using sockets would be a better solution. Then, you can use termbox-go or gocui for the client which connects to the server component.

Kind regards,

Roi Martin
