I’m currently in the process of writing a back-end for a small web application that I plan to deploy in my local environment. The application isn’t really relevant. The important bit is a new trick I learned while working on it. Within the back-end, at some point, I’m parsing an user-agent string. These strings are standardised and should follow the format described by HTTP Semantics. For convenience, I’ve chosen to go with uap-go to parse these strings and here lies the catch.
