x_do

XDo is a Crystal interface for libxdo, the C library that backs xdotool.

It exposes most of the functionality of xdotool, allowing users to write Crystal programs that manage windows in an X11 instance.

Installation

Add this to your application's shard.yml:

dependencies:
  x_do:
    github: woodruffw/x_do.cr

libxdo is required. On Debian-based systems, it can be installed via:

$ sudo apt install libxdo-dev

Usage

require "x_do"

XDo.act do
  active_window do |win|
    win.type "hello from Crystal!"
  end
end

Check out the examples folder for some practical examples.

Testing

The unit tests make the following assumptions:

• You're running an instance of X11
• You're running a window manager that's (mostly) ICCCM and EWMH compliant
• You have xlogo installed

To run the unit tests on the default X11 display (DISPLAY, falling back on :0):

$ crystal spec

Alternatively, the tests can be run on another X11 display, like a Xephyr or Xvfb instance:

# replace "99" with your display number
$ DISPLAY=:99 crystal spec

The util/xvfb-spec script can be used to run the tests inside a temporary Xvfb instance running Openbox:

$ ./util/xvfb-spec

TODO

• Complete bindings (grep "implement me!")
• Add error conditions (check return value of libxdo calls)
