Bit/Bool syntax in statplots.jl : "|" is not a unary operator
There's a bit of syntax that uses the . operator combined with the boolean || operator here:
https://github.com/GenericMappingTools/GMT.jl/blob/master/src/statplots.jl#L385
This works on newer versions of Julia, but not older versions. For example, that kind of syntax produces an error on the current LTS release of Julia, 1.6.7.
I think this code:
ind = ind_l .|| ind_h
Could be replaced with this code to in order to work in more places:
ind = collect(ind_l .| ind_h)
For a quick example, try running this test script with different Julia versions:
a=[true, false, true];
print("a = $a, typeof(a) = $(typeof(a))");
b = [true, false, false];
print("b = $b, typeof(b) = $(typeof(b))");
c = a .| b;
print("c = $c, typeof(c) = $(typeof(c))");
d = collect(a .| b);
print("d = $d, typeof(d) = $(typeof(d))");
e = a .|| b;
print("e = $e, typeof(e) = $(typeof(e))");
Sorry, not a good time for changes (will leave in vacations). But other things (don't remember which by memory) will not work in 1.6 as well.
Sorry, forgot this but I'm afraid there is nothing we can do here. GMT.jl does not build with Julia1.6 anymore since the introduction of the GMT_jll artifact because a chain of dependencies.
