Data::Hub::FileSystem::PerlModule -
Nothing exported by default
This module requires these other modules and libraries:
Error::Logical Error::Programatic Perl::Module Data::Hub::Util
PerlModule now inserts an @INC hook which looks for your file in Hub context. Meaning, you may now:
require '/web/scripts/util.pm'; require '../shared.pm'; require './share.pm';
from within your module. Note that this hook is inserted at beginning of @INC and will be run first. Modules which exist in the same directory as the calling module must be prefixed with './', as in:
require './share.pm'; # correct require 'share.pm'; # not found
When calling routines, if the module has defined an ACCESS function, it will be called (once per checkpoint) before calling a routine.
sub ACCESS { return 1; # return true (access allowed) or false (access denied) }
Note, do not eval, i.e., require, the contents until a sub is invoked. This is a security consideration, as eval is obviously dangerous. The intention is that one can access the contents of the file using this FileSystem object, without its contents being eval'd.
The downside is that we will return a valide CODE reference no matter what key is being fetched. This could be handled with some /^sub\s+(\w+)/ type magic in __parse_content.
The package name is determined from its absolute path
Apache2::Reload considers every value in %INC to be a file path. By default the hook is placed in %INC in place of the file name (see %INC in perlvar). Apache2::Reload will issue a warning when trying to reload the array, so we set the %INC entry ourselves.
The perl-module should begin with (on its own line!):
# PerlModule
which will be replaced with:
package _home_user_test_module_pm;
presuming the file is located at /home/user/test/module.pm
Note:
.------------------- No whitespace is allowed before the pound-sign (#) v # PerlModule ^ '------------------ Whitespace between the pound-sign and first word is optional.
If the content defines a package, e.g., package Local; no modification is performed.
package Local;
If the content does not include the # PerlModule crown, it will be inserted.
DEPRICATED
If the first line is:
package PACKAGE;
it will be replaced with the dynamic package name.
