Re: How to load the subs without running the script

in reply to SOLVED: How to load the subs without running the script

How about returning up front? Say for example, if contains:
#!/usr/bin/perl sub mysub {print "I want to see this\n"}; print "but I don't want to see this\n"; exit; # don't want to exit either
#!/usr/bin/perl use warnings; use strict; my $prog_code = do {local $/ = undef; open (my $fh, '<', '') or die "open error: $!"; <$fh>}; eval 'return;'.$prog_code ; die "eval error: $@" if $@; warn "trying mysub"; mysub();
The return gets executed as soon as compilation has finished, avoiding execution of the main body:
perl trying mysub at line 13. I want to see this Compilation finished at Wed Aug 4 10:08:26

Update: Removed intermediate subroutine and added sample output.

    Nice. I especially like your helpful summary of I should have included something like it, but your version abstracts the problem better than I could have done.
