Note that this project is largely unmaintained as I don't have the time to do or support more development. Please consider using this fork instead: https://github.com/jezek/xgb
XGB is the X Go Binding, which is a low-level API to communicate with the core X protocol and many of the X extensions. It is closely modeled after XCB and xpyb.
It is thread safe and gets immediate improvement from parallelism when GOMAXPROCS > 1. (See the benchmarks in xproto/xproto_test.go for evidence.)
Please see doc.go for more info.
Note that unless you know you need XGB, you can probably make your life easier by using a slightly higher level library: xgbutil.
go get github.com/BurntSushi/xgb go run go/path/src/github.com/BurntSushi/xgb/examples/create-window/main.go
I've forked the XGB repository from Google Code due to inactivty upstream.
Godoc documentation can be found here: https://godoc.org/github.com/BurntSushi/xgb
Much of the code has been rewritten in an effort to support thread safety and multiple extensions. Namely, go_client.py has been thrown away in favor of an xgbgen package.
The biggest parts that haven't been rewritten by me are the connection and authentication handshakes. They're inherently messy, and there's really no reason to re-work them. The rest of XGB has been completely rewritten.
I like to release my code under the WTFPL, but since I'm starting with someone else's work, I'm leaving the original license/contributor/author information in tact.
I suppose I can legitimately release xgbgen under the WTFPL. To be fair, it is at least as complex as XGB itself. sigh
What follows is the original README:
XGB is the X protocol Go language Binding.
It is the Go equivalent of XCB, the X protocol C-language Binding (http://xcb.freedesktop.org/).
