I'm writing a .bbappend for a recipe which contains a COMPATIBLE_MACHINE
pattern like this:
COMPATIBLE_MACHINE = "(machine1|machine2|machine3)"
Is there a way my .bbappend file can add to this pattern? I don't want
to disturb what's there, just add my machine as well.
Thanks

COMPATIBLE_MACHINE .= "|machine4"

It's just a standard regular expression.
COMPATIBLE_MACHINE = "(machine1|machine2|machine3)"
COMPATIBLE_MACHINE .= "|machine4"
Will result in a value of "(machine1|machine2|machine3)|machine4",
which is still a perfectly valid pattern, as far as I can tell.

Yes, this does seem to work. Any clues why most uses of COMPATIBLE_MACHINE
use the regex "(x|y|z)" instead of just "x|y|z"? Aren't they the same?

They are. No idea why people use the grouping.
