Learned today: Go templates

I built a library for loading configuration files that are actually Go templates, with some custom template functions for including values from other configuration files and loading secrets from files mounted by docker secrets.

If it turns out to be usable maybe I can open-source it some day, but for now it is proprietary.

Experiences with Go

For a few months now, I’ve been programming mostly in Go. Go is a programming language developed by Google, some kind of modern version of C.

Instead of listing here all the findings, I’ll just point to the excellent summary by Sylvain Vallez. With my couple of months of experience in Go, I can fully agree with Sylvain’s points.

When I think of Go, the first thing that comes to my mind is the error handling. Probably half of my code is for error handling:

if err != nil {
   return err

But overall I’m quite satisfied with Go. It gets the job done, and I like statically typed languages. If it had generics, I might even enjoy using it.
