Package xgbutil is a utility library designed to make common tasks with the X
|
|
server easier. The central design choice that has driven development is to hide
|
|
the complexity of X wherever possible but expose it when necessary.
|
|
|
|
For example, the xevent package provides an implementation of an X event loop
|
|
that acts as a dispatcher to event handlers set up with the xevent, keybind and
|
|
mousebind packages. At the same time, the event queue is exposed and can be
|
|
modified using xevent.Peek and xevent.DequeueAt.
|
|
|
|
Sub-packages
|
|
|
|
The xgbutil package is considerably small, and only contains some type
|
|
definitions and the initial setup for an X connection. Much of the
|
|
functionality of xgbutil comes from its sub-packages. Each sub-package is
|
|
appropriately documented.
|
|
|
|
Installation
|
|
|
|
xgbutil is go-gettable:
|
|
|
|
go get github.com/BurntSushi/xgbutil
|
|
|
|
Dependencies
|
|
|
|
XGB is the main dependency, and is required for all packages inside xgbutil.
|
|
|
|
graphics-go and freetype-go are also required if using the xgraphics package.
|
|
|
|
Quick Example
|
|
|
|
A quick example to demonstrate that xgbutil is working correctly:
|
|
|
|
go get github.com/BurntSushi/xgbutil/examples/window-name-sizes
|
|
GO/PATH/bin/window-name-sizes
|
|
|
|
The output will be a list of names of all top-level windows and their geometry
|
|
including window manager decorations. (Assuming your window manager supports
|
|
some basic EWMH properties.)
|
|
|
|
Examples
|
|
|
|
The examples directory contains a sizable number of examples demonstrating
|
|
common tasks with X. They are intended to demonstrate a single thing each,
|
|
although a few that require setup are necessarily long. Each example is
|
|
heavily documented.
|
|
|
|
The examples directory should be your first stop when learning how to use
|
|
xgbutil.
|
|
|
|
xgbutil is also used heavily throughout my window manager, Wingo. It may be
|
|
useful reference material.

Thread Safety
|
|
|
|
While I am fairly confident that XGB is thread safe, I am only somewhat
|
|
confident that xgbutil is thread safe. It simply has not been tested enough for
|
|
my confidence to be higher.
|
|
|
|
Note that the xevent package's X event loop is not concurrent. Namely,
|
|
designing a generally concurrent X event loop is extremely complex. Instead,
|
|
the onus is on you, the user, to design concurrent callback functions if
|
|
concurrency is desired.
