Most developers will agree that having automatic tests is a good thing. With good tests we can make changes to our code and test whether these changes causes old bugs to resurface, new bugs to appear, or current workflows to be broken.
In this tutorial we will have a look at how the default testing setup works in Nimble, the official Nim package manager/build tool which is installed along Nim.

The most distinct part of making
an epaper laptop is obviously the screen. And picking a screen for this

biggest available panel I could find with a somewhat reasonable price
was a 10.3” Waveshare panel that also shipped as a separate HDMI screen.

Sure, laptops have come a long way in the past twelve years, especially the battery life aspect has gotten much better. But there’s still nothing which beats epaper when it comes to the direct sunlight application. Whether or not I…

Error handling, a contentious and oft-discussed topic. Each language has some way of dealing with errors, be it error codes, result types, exceptions, something entirely different, or a mix. How to properly deal with things going wrong in our programs has been important pretty much ever since we started writing programs. Papers have been written about it, talks have been held on the topic, and countless libraries have been written to bring one languages way…

Recently I was met with an interesting problem when wrapping a C library in Nim. The library in question was MAPM, an older but quite complete library for dealing with arbitrary precision maths. Unfortunately the library doesn’t have much in the way of error handling. If something goes wrong it almost always writes to stderr and returns the number 0. And to be fair, there isn’t a whole lot that can go wrong in…
