Puppet users - May 2013 - What do YOU do to catch undefined variables

I''m still a puppet newbie and these days I''m struggling with
undefined
variables.  At least once a week I hit an error message like this: 
       Error: Failed to apply catalog: '''' is not qualified and
no path was
specified. Please qualify the command or specify a path.

IMO, the core issue is that Puppet has no mechanism for reporting read 
attempts on undefined variables.  So my question to the community is, what 
do YOU do to catch undefined variables?  If anyone has a first class 
solution I''d love to hear it.  But I''m also happy to consider
ANY means to
detect undefined variables. I may resort to explicitly listing all my 
variables and checking them with a custom ruby function.

Hmm, I''m using geppetto (the puppet eclipse integration from
cloudsmith)
which catches typos as they happen.

I''m very satisfied with it and undefined variables ain''t one
of my
problems ;-)

...finger slipped...
Thanks David,
I started using geppetto as well.  Yes, my error count has dropped 
significantly. The other thing I discovered is that hiera("name")
produces
a very clear error if the name doesn''t exist. So I moving toward that
as
well.
Cheers larry

I use vim with vim-puppet (and a bunch of other vim plugins).
It does syntax highlighting and does syntax and a few other check on saving
a file and lets you know if something is amiss.

I tried Gepetto but I can''t us that over an ssh connection to a server
if I
need to.

The vim plugin is the best you can find if you are already proficient
in vim somewhat. I use it in conjuction with
https://github.com/SirVer/ultisnips and it can''t be better. I found the
eclipse too heavy for my needs(although I use it for java development
where it shines)

Please satisfy my curiosity: how many puppet modules and/or .pp files do 
you currently have?

I currently have at least 40 modules in my setup.
Closer to 50 if you count the few I am still finishing off or converting.
A lot of those I wrote by hand with vim.

I have no idea how many .pp files that involves. Probably 50 X 5-7 so
probably over 300 .pp files
More if you count the few nodes definitions that aren''t in my ENC.

I installed geppetto and made a start at trying to work out how to get it
setup to replace my vim config but I gave up and just went back to using
vim.
It also eats a bunch of ram so it didn''t seem worth it just to use for
writing something I can do for very little memory footprint with vim.

I/We currently have 32 modules - some of these are of course third party
so they don''t count.

One of the modules is for our biggest project which consists of
different components and their configuration based on different
environment setups.  That module currently contains 36 *.pp files.

If you think vim can''t scale I can assure you that it can. Lately
I''ve
been using https://github.com/santana/puppet-cleaner to clean my pp
files and while it is still possible with eclipse to do the same it
feels so unnatural.

Maybe eclipse can give many more features like variable checking in the
current scope but I found that you also pay a price for that
integration. There is no free lunch.

In my case (I also use vim + vim-puppet), ~ 66 modules, ~200+ pp files.
