NAME

CPANPLUS::Hacking - developing CPANPLUS

CONTENTS

DESCRIPTION

This document attempts to describe how to develop with the CPANPLUS environment most easily, how certain things work and why.

This is basically a quick-start guide to people who want to add features or patches to CPANPLUS.

OBTAINING CPANPLUS

Checkout CPANPLUS from its GIT repository at <https://github.com/jib/cpanplus-devel> .

INSTALLING CPANPLUS

CPANPLUS follows the standard perl module installation process:



    perl Makefile.PL
    make
    make test
    make install



CONFIGURING CPANPLUS

When running perl Makefile.PL you will be prompted to configure. If you have already done so, and merely wish to update the Makefile, simply run:



    perl Makefile.PL JFDI=1



This will keep your configuration intact. Note however, if there are changes to the default configuration file Config.pm-orig, you should either delete your current config file and reconfigure, or patch your config file from the new entries in Config.pm-orig.

RUNNING CPANPLUS FROM DEVELOPMENT ENVIRONMENT

If you’d rather not install the development version to your site_perl directory, that’s no problem. You can set your PERL5LIB environment variable to CPANPLUSlib directory, and you can run it from there.

RUNNING CPANPLUS TESTS

Tests are what tells us if CPANPLUS is working. If a test is not working, try to run it explicitly like this:



    perl -I/path/to/cpanplus/lib t/XX_name_of_test.t 1



The extra ’1’ makes sure that all the messages and errors (they might be errors we’re testing for!) are being printed rather than kept quiet. This is a great way to find out the context of any failures that may occur.

If you believe this test failure proves a bug in CPANPLUS, the long output of the test file is something we’d like to see alongside your bug report.

FINDING BUGS

Sometimes you might find bugs in CPANPLUS’ behaviour. If you encounter these in a development snapshot, we’d appreciate a complete patch (as described below in the SENDING PATCHES section.

If it’s way over your head, then of course reporting the bug is always better than not reporting it at all. Before you do so though, make sure you have the <B>latestB> development snapshot, and the bug still persists there. If so, report the bug to this address:



    bug-cpanplus@rt.cpan.org



A good patch would have the following characteristics:
Problem description Describe clearly what the bug is you found, and what it should have done instead.
Program demonstrating the bug Show us how to reproduce the bug, in a simple of a program as possible
[OPTIONAL] A patch to the test suite to test for the bug Amend our test suite by making sure this bug will be found in this, and future versions of CPANPLUS (see SUPPLYING PATCHES)
[OPTIONAL] A patch to the code + tests + documentation Fix the bug, update the docs & tests. That way your bug will be gone forever :)

SUPPLYING PATCHES

Patches are a good thing, and they are welcome. Especially if they fix bugs you’ve found along the way, or that others have reported.

We prefer patches in the following format:
o In diff -u or diff -c format
o From the root of the snapshot
o Including patches for code + tests + docs
o Sent per mail to bug-cpanplus@rt.cpan.org
o With subject containing [PATCH] + description of the patch
You will always be informed if a patch is applied or rejected, and in case of rejection why that is (perhaps you can tweak the patch to have it accepted after all).
