[ww-devel] Making Perl modules available

[Andrew Dabrowski]

I should to my earlier message that I did restart httpd.  I'm running 
Arch Linux.


I thought it would be handy to make Perl's Data::Dumper available for 
debugging.  So on my office computer I added the line

     [qw(Data::Dumper)]

to ${pg}{modules} in defaults.config. But it didn't work, I still get an 
error.

This is the code in my pg file to display debugging info.

BEGIN_TEXT

     \{ Dumper @$socwelbest \}

END_TEXT

The display is this.



Here's the error message.


      Warning messages

  * |ERROR in old_safe_ev, PGbasicmacros.pl: <PRE>|
  * |## There is an error occuring inside evaluation brackets \{
    ...code... \}|
  * |## somewhere in an EV2 or EV3 or BEGIN_TEXT block.|
  * |## Code evaluated:|
  * |## Dumper @$socwelbest |
  * |##syntax error at line 2 of (eval 1132), near "Dumper @"|
  * |##</PRE><BR/>|
  * |at (eval 1051) line 1671|



It actually works fine when I use my own dumper function, defined in a 
pl file (apart from the fact that my dumper isn't as nice as Perl's).

What's the correct way to do this, i.e. add a aPerl module to webwork?
