Name of julia source file?

General Usage
1

How can I obtain the name of the current (or main/top) julia source file, from within the code?

2

Base.source_path()

I’m not sure if you are asking about the source code of functions, but if that’s the case, you can find the path of all the methods of any function f with methods(f)

There are also @__FILE__ and PROGRAM_FILE:

help?>  @__FILE__
  @__FILE__ -> AbstractString

  Expand to a string with the path to the file containing the macrocall, or
  an empty string if evaluated by julia -e <expr>. Return nothing if the
  macro was missing parser source information.
  Alternatively see PROGRAM_FILE.

help?> PROGRAM_FILE
search: PROGRAM_FILE

  PROGRAM_FILE

  A string containing the script name passed to Julia from the command
  line. Note that the script name remains unchanged from within included
  files. Alternatively see @__FILE__.
