New method in StringHelpers?

[Jeppe Nejsum Madsen]

Hi

I frequently find myself writing this method:

def emptyForBlank(in: String) = emptyForNull(in).trim match {
case "" => Empty
case s => Full(s)
}

Is something like this already in Lift? Couldn't find it....

Should we add it to StringHelpers? If so, I would like to rename
emptyForNull to blankForNull so as not to confuse the empty string
("") with Box.empty

+1 on adding it.

Of course you can do Full(s) filter (!_.isEmpty) ...

I simply use StirngUtils from apache-commons: StringUtils.isBlank(s), you can "static import" it, to be able to use just isBlank(s).
