in thread Including files

Let me get this straight:

  • ~/abc/moo.pl
  • ~/abc/cow.pm
  • ~/zyx/cow.pm
  • current directory is ~/zyx

moo.pl has:

  • use cow
  • use lib 'cow'

When i execute moo.pl, . is set to ~/zyx, so:

  • use cow means ~/zyx/cow.pm
  • use lib 'cow' means ~/abc/cow.pm

Did i get it right that, basically, there is a difference between the "current" directory and the directory of the pl file. Or, put another way, if i keep all my project files in the same directory, like we do during development, and the directory may change, and the directory i execute it from may change, "use lib" will work "as expected".

    No. Read lib. use lib 'cow'; is the standard, clean alternative to unshift @INC, 'cow'; It adds a directory to the search locations; it does not identify or pull in any files into the current program.

    if i keep all my project files in the same directory, ... "use lib" will work "as expected".

    No; if you do that, then you never need use lib ... at all, for the simple reason that '.' is in @INC by default.

    I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.
      Please give an example. I would like to get this clear.
