- Run mix credo --all to identify possible code optimizations
- Resolve most of the errors generated by credo such as:
- Numbers larger than 9999 should be written with underscores: 58_127
- Modules should have a @moduledoc tag
- Comparison will always return true
The previous strategy wasn't robust enough to detect typos in function
calls. For example, if you misremembered String.duplicate/2 as
String.repeat/2 the koan runner would hang and have to be restarted.
This is because the stacktrace for an error like that doesn't have line
numbers. To avoid the problem, we detect the first pieces of the
stracktrace that is in the koan module. I can't decide if that's a
perfect solution, but it seemed to work in my testing. Hoping to get
other's feedback.
