[bitbake-devel] [PATCH v2 2/2] lib/bb/utils: improve edit_bblayers_conf() handling of bblayers.conf formatting
Paul Eggleton

Fri Nov 20 04:11:16 UTC 2015
Make the following improvements to edit_bblayers_conf():
* Support ~ in BBLAYERS entries
* Handle where BBLAYERS items are added over multiple lines with +=
instead of one single long item
Also add some comments documenting the function arguments and return
values as well as a set of bitbake-selftest tests.
(This function is used by the bitbake-layers add, remove and
layerindex-fetch subcommands, as well as devtool when adding the
workspace layer).
