[Puppet Users] Accessing a fileserver file from a custom function

Hi James,

Using "puppet:///" and "file:///" in a way similar to what the File type offers from within a custom function is actually not that straight-forward, sadly. There is a lot of code which deals with resolving these URLs that deals with SSL certificates (since you can request an artifact from different Puppet Master), etc. I found it not that easy to work with outside of the File type, but perhaps somebody was more successful than I was (?) :-)

Here's a function that loads a files in puppet module path which you
can alter to suit your needs:
https://gist.github.com/3289446

This uses the same path as templates so instead of puppet:///, just
module_file(module_name/file_name), and you can look at the template
function for some ideas as well.

Hi

I'm struggling with a relatively straightforward custom function. All it
is designed to do is check for the existence of a file (on the
puppetmaster). It works fine when I specify the full path to the file, but
I would like to refer to a file in the module's files directory (e.g.
"puppet:///modules/apache/local-modules").

How could I acheive this please? I'd rather not hard-code the full path
as this would be brittle - how can I "resolve" the puppet:/// url to the
actual file location please?

(btw I need the function in order to execute classes/ types conditionally
depending ont he presence of files - it's for a defined type).

Thanks, James.

I only just noticed this, but I was actually modifying your gist KW to add
the puppet:/// parsing. I've forked it but can't see how to create a
pull-request for it (I'm fairly new to gihub I'm afraid).

Anyway, for anyone else wanting the function I've posted it here:
https://gist.github.com/3307835.

The next limitation is that it doesn't resolve template paths. That should
probably be in a separate function anyway.

I just notice Dan contributed something very similar that's much more
generic to stdlib:
