Subject [jira] Updated: (LANG-269) Shouldn't Commons Lang's StringUtils have a "common" string method?

     [ http://issues.apache.org/jira/browse/LANG-269?page=all ]

Scott Johnson updated LANG-269:

    Attachment: v2_StringUtilsTest.java.patch

> Shouldn't Commons Lang's StringUtils have a "common" string method?
> -------------------------------------------------------------------
>
>          Key: LANG-269
>          URL: http://issues.apache.org/jira/browse/LANG-269
>      Project: Commons Lang
>         Type: New Feature

>  Environment: generic
>     Reporter: Michael Dang
>      Fix For: 3.0
>  Attachments: StringUtils.patch, v2_StringUtils.java.patch, v2_StringUtilsTest.java.patch

> A method which accepts a string array and returns a string which is the common portion
of all the strings starting from the left, or more general form of that.
> This is very common operation.  For example, one may want to find the common directory
of a set of path strings.
> passing in:
> "/foo/f1.txt"
> "/foo/moo/f2.txt"
> "/foo/moo/f3.txt"
> should returns "/foo/"
> It is tedious to implement this in every project.  And I think Commons Lang StringUtils
should have some methods to help in this.
