There’s a tool that doesn’t come bundled with Guile and yet can be very useful in your day to day experience with it. This tool is Hall.
Hall helps you create, manage, and package your Guile projects through a simple command-line interface. When you start a new project, Hall creates a folder containing a scaffold of your new project. It contains a directory for your tests, for your libraries, for your scripts and for your documentation. This means you immediately know where to put the files you are hacking on.
In addition, the scaffold will include your basic “Autotools” setup, so you don’t have to take care of that yourself (see The GNU Build System in Autoconf: Creating Automatic Configuration Scripts, for more information on the GNU “Autotools”). Having Autotools set up with your project means you can immediately start hacking on your project without worrying about whether your code will work on other people’s computers. Hall can also generate package definitions for the GNU Guix package manager, making it easy for Guix users to install it.
