Module::Info::File - retrieve module information from a file
This POD describes version 1.00 of Module::Info::File
use Module::Info::File; my $module = Module::Info::File->new_from_file('path/to/Some/Module.pm'); $module->name(); $module->version(); $module->file(); $module->inc_dir();
Module::Info (SEE REFERENCES), are lacking functionality of being able to extract certain data when parsing a module directly from a file. I have therefor created Module::Info::File, which inherits from Module::Info and replaces the new_from_file method so the lacking data can be accessed (dir and name attributes). Apart from that you can use all the neat accessors from Module::Info.
Given the following structure in a file:
package Foo; 1; package Bar; 1;
Module::Info::File returns: Foo
package Foo; $VERSION = '0.01'; 1;
Given a file, it will interpret this as the module you want information about. You can also hand it a perl script.
After construction has been completed three attributes have been set in the object:
name
dir
file
So by using the inherited methods from Module::Info you can access the attributes.
In the script folder in this distribution is a small script called version.pl, which was the beginning of this module.
name, returns the package name of the file.
version, returns the version number of the module/file in question ($VERSION).
inc_dir, returns the dir attribute
file, returns the file attribute
A helper method to streamline the result set
In general please refer to the documentation on Module::Info for more details.
In list context the module returns and array of Module::Info::File objects, with which you can use the above accessors. The information in the objects might not be complete though (SEE: CAVEATS).
In the t/ directory of this distribution there is a test (Info.t), it includes some tests. These tests will test your installation of Module::Info (required by Module::Info::File), if the tests fail, Module::Info::File will be obsolete and can be discontinued.
Module::Info, by Mattia Barbon
script/version.pl
The module can somewhat handle several package definitions in one file, but the information is not complete yet, such as version information etc.
The method currently only support the following version number lines:
$VERSION = '0.01'; $VERSION = 0.01;
Eric D. Paterson scanned his complete CPAN installation and got and came across a few problems:
Unable to open file: <filename> - <operating system error>
If the constructor new_from_file is given a filename parameter, which does not meet the following prerequisites:
it must be a file and it must exist
the file must be readable by the user
There is a such no configuration necessary and Module::Info::File is expected to work on the same environments as perl itself.
This module is a sub-class of Module::Info, so the following direct dependencies have to be met:
Compability for older perls is no longer required, if somebody would require this I would be willing to invest the time and effort.
