I have the following in my site.pp
node "pclient.example.com" inherits default {}
When I try to start puppetmaster it gives me the following error
Starting puppetmaster: Syntax error at ''pclient.example.com''
at /etc/puppet/manifests/site.pp:24
When I change the node declaration to this
node ''pclient.example.com'' inherits default {}
puppetmaster starts up fine.
Is there a special difference between single quotes and double quotes within
puppet?

It''s kind of a weird situation. If you use double quotes, then you''d expect variables to get interpolated, but they won''t, because the string is evaluated at parse time, not run time. So, it always behaves like it''s single quoted, even when double quoted. I suppose the lack of support for double quotes is a bug, though. -- A motion to adjourn is always in order. --Robert Heinlein --------------------------------------------------------------------- Luke Kanies | http://reductivelabs.com | http://madstop.com

Just so that I don''t offend anyone. What I meant was. It''s
hard to find people willing to supply patches to an opensource project because
most of us(with exception) are just users of the product rather than developers
that can help out and actually do the coding. Though I''d be willing to
best 99% of the users of the product wish they could contribute code.

I''m by no means a C developer, but I was able to contribute plenty of patches to Cfengine, and although Puppet''s code paths are never as clean as I would like, they can''t hold a candle to Cfengine''s code labyrinth. In the two years I worked heavily on and with Cfengine, I went from being afraid of C and large programs to being confident enough to write my own, and all it took was my trying. Sure, this bit is a modification of the parser, but it''s not as hard as you apparently fear, and Ruby is an insanely approachable language. Most of the rest of Puppet is pretty darn approachable, especially for those areas most people are interested in, like adding and modifying providers. Check the code out, then spend half an hour looking around, seeing if you can fix some of the things that annoy you. The worst you''ll lose is half an hour, but you might gain both the features you''re dreaming about and the ability to start bugging other people about how easy it is to contribute. :) -- Sabbagh''s Second Law: The biggest problem with communication is the illusion that it has occurred. --------------------------------------------------------------------- Luke Kanies | http://reductivelabs.com | http://madstop.com

I''ve just found that the biggest difference between those who can contribute code and those who can''t is that those who can have tried to do so, and those who can''t have not. I think most of you would be surprised at how easy it is to contribute. Remember, good judgement comes from experience, and experience comes from bad judgement. The only way to get good at something is to be wrong as often and as spectacularly as possible. I think I''m pretty patient with users, but I''m fabulously patient with developers -- I really want others helping with the code base, and I''ll gladly walk you through any patches you provide, providing feedback and advice. Feel free to ping, say, Jeff McCune or Matt Palmer if you have doubts. Both of them started in the community with no apparent plans to develop, yet both of them have added significant functionality to the code base. That being said, if anyone has any recommendations on things I can do to make it easier to contribute, I''m all ears. Feel free to email me directly if you prefer. One thing I think would help is to convert to a distributed version control system, since SVN and its ilk make it harder to maintain your own branches while you''re experimenting. -- The brain is a wonderful organ.

It probably took less than two hours to find and fix a simple bug, which doesn''t seem to bad to me since this was my first exposure to ruby code.> One thing I think would help is to convert to a distributed version > control system, since SVN and its ilk make it harder to maintain your > own branches while you''re experimenting. >Having gone down that road (and back) I''d advise against that. Distributed systems tend to be more complex and harder for people to deal with when they don''t already have a firm grasp of VCS concepts. Subversion has the advantage of being extremely easy to get started with (you really only have to explain checkout, update, and diff to someone just getting started) and having GUI tools (like TortoiseSVN) that can get them started. Most of the people who fall into this category won''t be creating their own branches anyway, and when you get serious developers involved who want to create their own branches, you can either trust them to be serious developers and give them the ability to create branches in the repository, or they can use svk and get the benefits of a distributed system without forcing the casual user and occasional developer to deal with anything more complex than the basic subversion tools. -- Jason Kohles email@jasonkohles.com http://www.jasonkohles.com/ "A witty saying proves nothing." -- Voltaire
