In this thread we’ll publish all articles written in the Adroll Engineering Blog that are related to Elixir


Let’s start with one about how to use dialyzer on a huge project without slowing down your development process.


Should be using Erlex for the warning pretty printing =)

Except they seem to be using rebar3 and erlang, not elixir, so an erlang format is probably much better for them. ^.^

New article about Hank


Hank is interesting. However, it did seem to callout function definitions that have variables prefixed with _ as ‘having unused variables’. Worth filing a GitHub issue?

It only warns you about them if they’re in fact unused. That’s the whole point.
I explained the situation in further detail (and with some examples) in this discussion.

In a nutshell: The warning is not about unused variables, it’s about unneeded function parameters.
