[Melbourne-pm] CPAN module

Wed Mar 8 20:41:03 PST 2006

That's a good idea, but I don't know if the powers-that-be at CPAN will
allow it.

I don't know your code, but do you just add functions, or are you
changing functions in H::T ?

What I am driving at is you release your extension with "use base
qw(HTML::Template);" - so your package is only your extensions,
everything else falls back to "default" H::T 

Can you separate your work cleanly from the default H::T ?

Correct - and he has every right to make his own decisions.

That said, if I take a leaf from Linux kernel development or the Gentoo
package tree, I can easily overlay a snapshot branch of any package I
like, simply by setting an environmental variable.  The point being that
I can happily release my own version of H::T without breaking anyone
else's version.  And I can do this without forking the namespace.

Having looked at CPAN module install semantics, I was under the
impression that it was possible for two independent people to upload
their modules.  Then using the cpan shell, a user could fetch a specific
developer's version of a package, as in:

cpan>  install M/MA/Mathew/HTML-Template-2.8_01.tar.gz

thoughts?

The decision to create a new namespace has already been made for you by
the H::T developer - he doesn't want your extra features in his
namespace, so you need another.

Did he give a reason - I suspect he felt the new features didn't fit
with his idea of what H::T should do. The doco and design seem to
indicate they have refined H::T to be exactly what they want.

hmm... I was hoping there was something more akin to a 'developer tree' 
which would allow updates to a package, but not  be part of an 
"official" package.

Hi folks,

I use a CPAN module called HTML::Template, which is used as a

web-page

templating engine (in a similar vein to Template-Toolkit).

I have made some changes to increase its functionality - which

amounts

to about 20% of the code (ie: not a small patch).  I have suggested

that

some of these changes be added to the real module, but the developer
isn't interested.

Since I dont really want to do a complete fork of the code, as the
existing community is quite lively...  The question is, is there a

way

to release a modified version into CPAN?

No not really, and that would not be fair either - you can't have two 
bosses of one bit of code.

But you have already touched on the answer - fork it and release as a 
new module.

eg:

    HTML::TemplateX

Or maybe

    HTML::Template::Extended

Once you do that - and that is fair and safe - you can then encourage 
the use of your changes. If the changes are good and acceptable, then 
people will use that module instead - eventually it will become the 
standard, and probably even get incorporated or replace the old one.

This is not unprecedented - quite common actually :-)

Microsoft is not the answer. It's the question. And the answer is no.
