This article starts a new series of blog posts about “bug hunts”. In these articles, I will go through a recent bug in Brian (or one of its dependencies) and describe all the steps I used to find the source of the bug and how I fixed it. I will try to not only focus on the Brian-side of things, but also show some general tools like
git bisect or “monkey patching” that can be helpful to find the source of these nasty critters (no actual bugs were harmed during the making of this blog post).
Let’s start! Today’s bug will be about equations, and more specifically about their LaTeX representation. As most of you probably know, Brian can represent equations, quantities, etc. in LaTeX. This representation can then either be included in a LaTeX document or directly rendered for example as the output in jupyter notebooks.
