Description Darren Hart 2012-03-13 16:13:06 UTC 
Difficulty: Hard
Estimate: 3 Days
Submitter: dvhart

bbvars.py does a rather dumb regex search for things vaguely resembling variables, the bitbake parser knows how to do this properly. 

Example use of bbvars:


$ scripts/contrib/bbvars.py -d documentation/poky-ref-manual/poky-ref-manual.xml -t meta/conf/documentation.conf -m meta

These days you would use tinfoil to do this. Here's some introductory material:

In the above example I believe the path to the XML file these days should be documentation/ref-manual/ref-variables.xml .
