universal @INC?

Post #1 of 3 (2385 views)

It seems that if I do
[! use lib '/whatever/wherever'; !]
in one file, it doesn't help when i do
[! use MyModule; !]
in another file.
So what is the best way to set @INC so it applies to everything?

Also, is there any way to import symbols so that they are
available everywhere without qualification?
So I would do this in myfuncs.epl :
[! use MyModule qw(func1 $VAR1); !]
and then I do elsewhere
[! Execute 'myfuncs.epl' !]
[+ func1() +]

If you use mod_perl, than you should put it in a startup.pl that you
include with PerlRequire in your httpd.conf.

For CGI, just include it in the embpcgi.pl

You could use Embperl_Top_include to include some code at the top of
every page, for example some use statements.

You can also use Execute ({inputfile => '...', import => 1}) to import
subs that are declared va [$sub$]

It seems another solution is to do a "SetEnv PERL5LIB ..."
in .htaccess which works for both CGI and mod_perl.

Instead I'm now doing Execute ({inputfile => '...', package => __PACKAGE__})
which has the benefit (or deficit for perhaps other cases) that it'll get
all symbols, not just the [$sub$] symbols.
