Description
A common need in GSPs is to shorten long text with elipsis ...
I know it's not that difficult for app developers to add a method to String metaclass or mixin StringUtils from Commons Lang in BootStrap. But I think this is so common that a standard grails tag must support it.
I can see two alternatives:
- add optional int parameter "abbreviate" to the existing fieldValue tag.
- add a new "abbreviate" tag with "bean" and "field" parameters like fieldValue and a "maxlength" parameter to set max text length.
See abbreviate method in http://commons.apache.org/lang/api-2.5/org/apache/commons/lang/StringUtils.html

Luke Daley I think has a high quality implementation of this. I think there are issues with the commons stuff.
I think it was his implementation that allows the ellipsis at start, middle or end - which is very handy.
A tied-in issue is cleaning up HTML to plain text before you summarize. Summarizing HTML gives bad markup

This should be useful, it got my vote.
I'm in favour of adding a parameter to the fieldValue tag.
