Hi, Quoting Aaron Biver (2019-06-28 18:44:40) > Is there such a thing as zero padding a number in a recipe (or vice versa? > I'd be just as happy starting with a zero-padded number, and converting it > to non-zero-padded.
In bitbake you could do this with inline python:
NUMBER = "1"
NUMBER_PADDED = "${@"{:02d}".format(d.getVar("NUMBER", True))}"
NUMBER_PADDED2 = "0012"
NUMBER2 = "${@str(int(d.getVar("NUMBER_PADDED2", True)))}"
I have not tested this and it could possible be done more elegant, but
it should work.
