Shotgun Ruby is a Ruby gem based on the shotgun screenshotting tool. It is mainly developed as a fast screenshot tool for the loader_detector project.

ShotgunRuby can be used via the ShotgunRuby.screenshot( window_id, screenshot_path ) method.

It requires 2 parameters.
1. The id of the window it is supposed to screenshot 2. The path to where it should save the screenshot

When the screenshot is successfully taken the function return the filepath back.

For ShotgunRuby to be able to work it needs a system that uses X11.

The original shotgun code is written in Rust and for building its native extension you require the libclang-dev library.

sudo apt install libclang-dev

You can install Shotgun Ruby using Rubygems:

gem install shotgun_ruby

Alternatively you can clone the repository and install it manually using the Rakefile

rake compile build install
