In GMT, when both symbol and size are read from files, the
-S
option can be specified without arguments. Thus,style=""
orstyle=True
should be valid.However, currently we check
kwargs.get("S") is not None and kwargs["S"][0] in "vV"
which doesn't make sense ifstyle
is not a string or is an empty string.This PR fixes the checking of the
style
parameter.Strictly speaking, it's a bug, but I don't want to add one more test for such a minor change. So mark it as "maintenance" and "skip-changelog".
