whereami(radius \\ 2)

View Source (since 1.5.0)

Prints the current location and stacktrace in a pry session.

It expects a radius which chooses how many lines before and after the current line we should print. By default the radius is of two lines:

Location: lib/iex/lib/iex/helpers.ex:79

77:
78:   def recompile do
79:     require IEx; IEx.pry()
80:     if mix_started?() do
81:       config = Mix.Project.config

(IEx.Helpers) lib/iex/lib/iex/helpers.ex:78: IEx.Helpers.recompile/0

This command only works inside a pry session started manually via IEx.pry/0 or a breakpoint set via IEx.break!/4. Calling this function during a regular IEx session will print an error.

Keep in mind the whereami/1 location may not exist when prying precompiled source code, such as Elixir itself.
