[chef] Re: Re: Re: Custom resources and providers

[Niall Napier < >]

Thank you all for your replies,

After some head-scratching and with the help you provided above I've implemented a basic resource/provider for Mercurial and would appreciate all of your feedback.

I have uploaded it to https://bitbucket.org/niallsco/chef-cookbooks/ and released it under an Apache 2.0 license. 

I've also written a brief tutorial on how to use the chef-hg resource and posted it online at http://napes.co.uk/blog/chef-hg/

Please let me know if you have any comments or questions, as mentioned all feedback appreciated.

Regards,

Well I have written a few custom Chef Resources in my cookbooks.

Those cookbooks are: dreamcat4/site-cookbooks/restart and
dreamcat4/site-cookbooks/rvm on GitHub. Actually the file is always in
/libraries/ subfolder of the cookbook.

But whatever your preconceptions - we all recommend that you give LWRP
a shot first of all. Its reasonably powerful and if you can do it in
LWRP then thats going to be the preferred / supported way.

Although im not sure exactly what Opscode would want from you in terms
of contributing an LWRP Mercurial VCS Resource back into their
codebase - its an afterthought. I assume thats what you were really
trying to figure out there.

I found the following page on the Opscode wiki http://wiki.opscode.com/display/chef/Providers but it suggests that implementing a Provider should be integrated into the chef package.
