elisp: Is there a way to get the name of the current .el module (like __FILE__ in C)?

Question

At the top of my elisp module, I want to do something as simple as:

(message (concat "Loading " (expand-file-name (current-elisp-module) ".")))

Answer 1

You can use the variable load-file-name, which is set by the function 'load. The documentation string is:

load-file-name is a variable defined in `lread.c'. Its value is nil

Documentation: Full name of file being loaded by `load'.

Note: buffer-file-name as a routine does not work as you might expect it to.
