Print the current stacktrace in Elixir

Stacktrace, backtrace, callstack, in Elixir its stacktrace and it's available via Process.info/2 using the :current_stacktrace item:

Process.info(self(), :current_stacktrace)

And to print it:

IO.inspect(Process.info(self(), :current_stacktrace), label: "STACKTRACE")

I'm also learning that Process.info/2 takes a pid and an item as arguments. When you call Process.info/1 with just the pid you only get a subset of the info available, not everything.

The items available via Process.info/1 are listed in the erlang documentation here.

The additional items available via Process.info/2 are listed in the erlang documentation here.

You may note that backtrace is also an item that is available via Process.info but it contains more information than you are might need to figure out where you are in the code.
