Bitcoin is all over the news, this time with big investors pouring money into it, a global pandemic that put the economy on hold, and governments printing money like crazy. Price raises, it is a bubble again. Maybe it is responsible this time to at least try to learn about Bitcoin without rushing to get it like everybody else seems to be doing again.

When working on the interface to notmuch I stumbled upon the case where iterating over messages and iterating over filenames produced the same code structure only changing the functions being used. I hate to see code duplication and thus I went out exploring for solutions available in Guile to solve this issue.

Manually creating the bindings for a sizable C program is a lot of work, also it is not very rewarding. I’m lazy and don’t want to do that. I looked around for what other options I have and I was surprised about the solution.

On the previous post I covered how I can call external programs as new processes and interact with their inputs or outputs. Here I will use directly the foreign libraries written in C using Guile’s foreign function interface . In this series of posts I record how to use Guile as a scripting language and solve various tasks related to email work.

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.
