HTML::Perlinfo::Loaded - Post-execution HTML dump of loaded modules and
environment variables
#!/usr/bin/perl
use HTML::Perlinfo::Loaded;
...
This module installs an at-exit handler to generate an HTML dump of all the
module files used by a Perl program. As an added bonus, environment variables
are also included in this dump. When used under mod_perl, the module will show
you preloaded modules in the HTML page too.
Since the "dump" is a complete HTML page, this module is a good
debugging tool for Web applications. Just make sure you print the content-type
header beforehand or you will get an internal server error (malformed header).
Note that the HTML::Perlinfo function 'perlinfo' has an option called
INFO_LOADED that will produce the same result. In other words, there is more
than one way to do it! Observe:
use HTML::Perlinfo;
perlinfo(INFO_LOADED);
The result will be the same if you say:
#!/usr/bin/perl
use HTML::Perlinfo::Loaded;
...
There is no difference, except using the perlinfo option gives you greater
control. You could always control HTML::Perlinfo::Loaded with a pound sign (a
comment on/off), but if you are using mod_perl it makes more sense to add
HTML::Perlinfo to your startup file and then call perlinfo(INFO_LOADED) when
you want to dump.
