Hi Franco,
thanks for contributing!
I think something like firstcol would be a better name. Trim sounds more
like removing whitespaces. I also think that you don't have to do the
trim(). All strings are trimmed during the map building process (but
that can be wrong - I haven't looked through the code...).
I wonder if its easily possible to configure the column number that is
returned, so something like
'${destination|col:2.;}'
returns the second entry of destination with the column separator ;.
Maybe this could be useful for other purposes?
Can you also please add some documentation to your patch? Steve has
written the style documentation with asciidoc which is available in SVN.
It would be great if you can add some words about this new function!
Have fun!
