How can I list all of my aliases in `iex`?

Question

Sometimes I forget what I've previously aliased via alias in an iex session.

I can check by simply entering the alias I want to use, e.g. iex(314)> SomeName, or the default for multi-part module names, but it'd be also be nice to see any other 'non-standard' aliases I've already setup.

Answer 1

Run __ENV__.aliases:

iex(92)> __ENV__.aliases
[
  {Repo, SomeProject.Repo},
  {Customer, SomeProject.Customer},
  {Merchant, SomeProject.Merchant},
  {Util, SomeProject.Integration.Util}
]
