Hi Peter,
I've looked over the wiki and as far as I can see, 'when' tags used inside 'conditional' tags only work on another input variable's values.
I would like to be able to do is a conditional based on the file format of an input file. For instance, a tool might take XML or tabular files, and need to show additional parameters for one input type but not the other.
Does this enhancement idea seem useful?
Peter
Hello again,
I'd still like to be able to show different tool parameters for different input file formats - is anyone else interested in using or working on this?
Yes! Im using that for a few of my tools, but currently the user need to choose the file format, that is suboptimal :(
Thank Bjoern & John for your comments back in March. I've just filed a Trello card for this: https://trello.com/card/-/506338ce32ae458f6d15e4b3/837 This was prompted by revisiting my Venn Diagram tool, where it would be nice to offer a column number parameter when using a tabular input file (but this is not appropriate for FASTA files): http://toolshed.g2.bx.psu.edu/view/peterjc/venn_list Peter
