Using x in prerelease causes error #75
Description
Given the version 0.1.0-x, ParseRange returns the following error:
Could not get version from string: "<"
Replacing the x with another character fixes the problem (e.g. 0.1.0-y).
This appears to be related to x being used to denote wildcards as implemented in #27:
Line 330 in 4487282
This can be reproduced with the following test:
func TestExpandWildcardVersion(t *testing.T) {
tests := []struct {
i [][]string
o [][]string
}{
{[][]string{{"foox"}}, nil},
// FAILING TEST
{[][]string{{"0.1.0-x"}}, [][]string{{"0.1.0-x"}}},
{[][]string{{">=1.2.x"}}, [][]string{{">=1.2.0"}}},
{[][]string{{"<=1.2.x"}}, [][]string{{"<1.3.0"}}},
{[][]string{{">1.2.x"}}, [][]string{{">=1.3.0"}}},
{[][]string{{"<1.2.x"}}, [][]string{{"<1.2.0"}}},
{[][]string{{"!=1.2.x"}}, [][]string{{"<1.2.0", ">=1.3.0"}}},
{[][]string{{">=1.x"}}, [][]string{{">=1.0.0"}}},
{[][]string{{"<=1.x"}}, [][]string{{"<2.0.0"}}},
{[][]string{{">1.x"}}, [][]string{{">=2.0.0"}}},
{[][]string{{"<1.x"}}, [][]string{{"<1.0.0"}}},
{[][]string{{"!=1.x"}}, [][]string{{"<1.0.0", ">=2.0.0"}}},
{[][]string{{"1.2.x"}}, [][]string{{">=1.2.0", "<1.3.0"}}},
{[][]string{{"1.x"}}, [][]string{{">=1.0.0", "<2.0.0"}}},
}
for _, tc := range tests {
o, _ := expandWildcardVersion(tc.i)
if !reflect.DeepEqual(tc.o, o) {
t.Errorf("Invalid for case %q: Expected %q, got: %q", tc.i, tc.o, o)
}
}
}Result of this test is: Invalid for case [["0.1.0-x"]]: Expected [["0.1.0-x"]], got: [[">=0.1.0-x" "<"]]
At the very least, it would be helpful to call out this corner case in the docs if fixing this would be challenging due to breaking changes.
