In this series of posts I record how to use Guile as a scripting language and solve various tasks related to email work.

Managing my email with Guile - A shell script alternative

Most of the pre-processing work of my emails was already solved with a combination of a bash script, which uses the notmuch cli and the python package afew . However, I’m learning Guile and I need a real task to solve to practice the language.
