¶Creating a new Guile Scheme library
Today we’re going to experiment with using Guile Hall and Guix to create a new Guile Scheme library from scratch! Guile Hall is a tool that can create a complete Guile project even with its own Guix packaging configuration.
¶Our Project
To test out the development workflow with these tools, we’ll write a simple URL route handling library like you might see in a minimal web programming framework (think Express.js, Flask, etc).
/api/things
/api/things/{thingId}/doSomething
/api/widgets/{widgetId}
The goal will be to produce a simple library with basic tests and then consume it from a Guile Scheme script inside of a guix shell which has our Guile library installed!
¶Steps to use Hall for a project:
# Creating a project cd ~/projects hall init --author "Your Name" project-name -x # Initializing the project build cd project-name hall build -x guix shell -Df guix.scm -- autoreconf -vfi && ./configure && make check # Building the project for development guix shell -Df guix.scm -- make check
NOTE: The guix.scm file that is written out for --type local is wrong by default! Change source to (local-file "project-name-0.1.tar.gz")
To use your library as a Guix package:
# Make the local tarball guix shell -Df guix.scm -- make dist # Run a guix shell with the library installed guix shell -f guix.scm guile # The guile part is needed!
Now you can load up your module in an arbitrary script!
