How to know that latexmk picks up my configuration file?

Question

I've put .latexmkrc file into my working directory, but it doesn't seem to be doing anything. Is there a way to check that latexmk picks up my configuration file?

Could someone provide the complete definition of the file as an answer, step by step, for dummies like me? — Andriy Drozdyuk, Jun 12 '12 at 16:37
You could run it with -norc and see if it makes a difference. — N.N., Jun 12 '12 at 17:41
That's the thing - I can't really see if it makes a difference, because there are hundreds of lines of output... — Andriy Drozdyuk, Jun 12 '12 at 18:40

A latexmkrc file is just perl code, so you can just put a print statement in it:

# .latexmkrc

print("Hello, world!  I'm a .latexmkrc\n");

# rest of .latexmkrc

For more about useful assignments to make, see the documentation.

Works like a charm. I put print statement first in my config, and it shows up as the first line in the output. – Andriy Drozdyuk Jun 13 '12 at 01:55
Does someone know why print(__FILE__ . "\n"); returns (eval 13)? – Hotschke May 21 '19 at 13:21
@Hotschke because you're trying to have perl execute python code? – Matthew Leingang May 21 '19 at 16:34
Why do you think this is python code? __FILE__ is known to perl. – Hotschke May 21 '19 at 16:36
str.str is perl string concat not python (str+str). – Hotschke May 21 '19 at 16:37
@Hotschke you are right, of course. I should have googled before making a snide remark blush. I don't know why, then. – Matthew Leingang May 21 '19 at 16:37
@Hotschke The perl monks have some wisdom to share on this subject. – Matthew Leingang May 21 '19 at 16:49
@MatthewLeingang: Unfortunately, their wisdom does not help me. – Hotschke May 21 '19 at 17:11
@Hotschke Yes, it's not obvious to me either. The issue, I think, is that the .latexmkrc file is run through perl's eval function, which may not know what file it is reading. I will poke at this when I get a chance next. – Matthew Leingang May 21 '19 at 17:16
