[PATCH 1/1] insane.bbclass: Added QA test for expanded ${D}

[PATCH 1/1] insane.bbclass: Added QA test for expanded ${D}

[Alejandro Hernandez]

Checks in FILES and pkg_* variables, solves common mistake of

using ${D} instead of $D and warns the user accordingly.

Hi Alejandro,

Looks good, but some small points:

Rename this to expanded-d for consistency with the other symbols that use -
instead of _.

No need to document idioms, remove this comment.

This doesn't name the package which makes it tricky to find in large builds.

Would it be simpler to do "bbvar = d.getVar(var + "_" + pak, False)" so you 
don't get the expanded value, and then just check for ${D}? I suppose it would 
save one extra variable and a couple of expansions.

Alejandro answered this point in the original thread:

"using the existing package variable handling infrastructure within the
class, ends up expanding the variables before being able to check them ,
using getVar('FOO', False) is useless in this case, any suggestions?"
