The .iex.exs file is a "must have" convenience.
You can use it to set aliases, set imports and add define helper functions for every IEx session you run!
Here's what's in my global one:
import_if_available(Ecto.Query)
import_if_available(Ecto.Changeset)
defmodule AC do
def update(schema, changes) do
schema
|> Ecto.Changeset.change(changes)
|> Repo.update()
end
IEx.configure(
colors: [
syntax_colors: [
number: :light_yellow,
atom: :light_cyan,
string: :light_black,
boolean: [:light_blue],
nil: [:magenta, :bright]
],
ls_directory: :cyan,
ls_device: :yellow,
doc_code: :green,
doc_inline_code: :magenta,
doc_headings: [:cyan, :underline],
doc_title: [:cyan, :bright, :underline]
],
default_prompt:
[
# ANSI CHA, move cursor to column 1
"\e[G",
:light_magenta,
# plain string
"🧪 iex",
">",
:white,
:reset
]
|> IO.ANSI.format()
|> IO.chardata_to_string()
)
end
And in this project, my local .iex.exs has:
alias Campsite.{Accounts, Content, Extract, Game, Repo}
alias Accounts.{User, Credential}
alias Content.{Article, Comment, Episode, Podcast}
alias Game.Request
With these in place, every time IEx starts up, commonly used modules are automatically aliased, Ecto queries are easier and there's a nice 🧪 prompt making it clear the terminal is in IEx. 🎉
