I have written an application that outputs to a number of formats including csv/tab delimited/fixed length. One option I have played with is a Dancer app that produces JSON that is consumed by the same app. Its output will be similar to excel/access in columns and rows. In my current application I tried adding 'use Dancer;' and adding a route and start line 'dance', but it looks like Dancer is clobbering Getopt::Long which I also use. I really don't want to write a separate application since I won't know until run-time on what output I want. Has anyone ever tried this before? Jonathan Otsuka
