OK, the current behaviour seems daft to me. Can anyone explain why this is
as it is?
StringUtils.sliceFirst("abc", "") = "abc"
StringUtils.sliceFirst("abc", "d") = ""
StringUtils.sliceFirstRemainder("abc", "") = ""
StringUtils.sliceFirstRemainder("abc", "d") = "abc"
I would expect the exact opposite:
StringUtils.sliceFirst("abc", "") = ""
StringUtils.sliceFirst("abc", "d") = "abc"
StringUtils.sliceFirstRemainder("abc", "") = "abc"
StringUtils.sliceFirstRemainder("abc", "d") = ""
I would expect slice first to return the text before the first separator. An
empty string is found at position zero, so it should return "". Separator
"d" is not found, so everything before it is the whole string.
I'd like to change this, but why is it as it is???
