Hi all -

Super quick - I could have SWORN there was a way to segregate your recipes
by folder named after the platform you’re targeting.

I can’t seem to find that document page and I’m really trying to minimize
what the recipe has in it for a given platform.

Anyone know what I’m talking about here or do I have my wires crossed with
another part of chef?

I think I may be thinking of file specificity - can you use this in the
recipe directory as well or are you forced to do platform?(test)?

I believe you've "got your wires crossed" with templates and files.

Yeah, digging deeper, it seems like people have asked for this same
feature. Just stinks trying to support multiple platforms (both *nix AND
windows) and multiple architectures on each.

Just for a simple jdk installation, that becomes all these if or case
blocks whereas it'd be much nicer to use libraries+attributes and segregate
the recipes based on platform/architecture just like the files.

Is that nuts?

Ideally your recipes shouldn't be that different between platforms, so
a few conditional blocks keying off of platform is generally more
sustainable. Trying to keep parallel paths for different platforms
isn't a very DRY approach. That said, you could use an include_recipe
keying off of the platform to break out just those specific pieces and
come back into the main flow is probably a better approach. Take a
look at how the annoyances cookbook works:

Ohhhhh - I like that!

The real rub is supporting windows I guess. Once the platform is
determined it is windows, then all bets are off and things all respond
differently.

Essentially I wanted to bury that stuff away and in the default for a given
recipe, do the platform test, put the MAIN heavylifting in a library (or
include a recipe) but have the testing and idempotent type things
squirreled away.

Supporting windows is messy work :-/

Thank you though - I'll keep this technique in mind!!!
