.source(file_alias, path) ⇒ Object

Loads file.

Files that were added last are considered to be more important i.e. if you have

source :file1, '...'
source :file2, '...'
source :file3, '...'

all operations will be executed from file3 to file1

Parameters:

  • file_alias (Symbol, String) —

    alias for file

  • path (String) —

    full path to config

Raises:

  • (StandardError)
