---------------------------------
Resolution: Fixed
> camel-core - Add substring function to simple languge
> -----------------------------------------------------
>
> Key: CAMEL-20931
> URL: https://issues.apache.org/jira/browse/CAMEL-20931
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 4.7.0
>
>
> Its common to clip in start or end of a payload, like first and last char or
> something.
> We can add a substring command to make this easier, and make it much easier
> to clip N last elements than today in pure Java String.
>
> substring(1) // clip first char
> substring(-1) // clip last char
> substring(1,-1) // clip first and last char
> So numbers that are negative are from the tail end
> And it should silently ignore if the string is empty or shorter etc.
