Gregor B. Rosenauer commented on LANG-405:
------------------------------------------
Thanks for looking into this little feature request:)
@Henri: Yes, in BeOS this function was used to shorten filenames for display in
the desktop filemanager, Tracker, and was available in the standard API. It was
a cool feature, like most other aspects of the BeOS, way ahead of its time,-)
@Sebb: good question, I think it would be way too much effort to put in word or
even sentence recognition (which words or sentences make sense in which
language etc.). I would be happy enough to have an equal number of characters
at each side. This would be enough for the main use cases I encountered so far:
1. there are multiple Strings and cutting off the beginning/end of a String is
not enough to differentiate them, like in user interfaces (tables etc.).
2. you need an excerpt of a String that is too big as a whole, e.g. logging an
XML-document where the beginning/end is both interesting but the middle part is
big and not needed as a whole
> StringUtils.truncate() to cut out middle part of a String

> Key: LANG-405
> URL: https://issues.apache.org/jira/browse/LANG-405
> Project: Commons Lang
> Issue Type: New Feature
> Affects Versions: 2.2
> Reporter: Gregor B. Rosenauer
> Priority: Minor
>
> It would be handy to have a String method that cuts out the middle part of a
> String such that as much as possible is kept from the start and end of the
> String, but the middle part is replaced by an ellipsis "..."
> BeOS had a function like this, but it's poorly documented, missing examples:
> http://www.beunited.org/bebook/The%20Support%20Kit/String.html#Truncate()
> e.g.:
> A very long text with unimportant stuff in the middle but interesting start
> and end to see if the text is complete.
> becomes:
> A very long text...to see if the text is complete.
