Dialyzer: A Static Type Analysis Tool
The first word that people might hear is dialyzer. Can you tell everyone what dialyzer is doing? The way it works is it's compiling your code and then looking at like the bytecode or what's compiled down into the beam. Dialyzer will spit out errors, some of which are notoriously vague and confusing. It has a list of known errors. There's a mixed dialyzer explain to give you more details on a specific type if you are confused.
Dialyzer is something that eventually everyone hears about in the Elixir community. It's a static code analysis tool that has both fans and detractors, and with good reasons on both sides! We talk with Noah Betzen about how he brought Dialyzer to several mature Elixir projects. He wanted the benefits of finding and fixing bugs and to prevent new problems from being added. He shared tools, strategies and other resources for how to get started without stopping everything to fix all the existing problems. If you've ever tried to add Dialyzer to a project and aborted, then this discussion may give you the courage and the tools to try again!
