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 :( But i have no time for a proper solution, a few of your reviews are also waiting ... :( Sorry, Bjoern

Thanks,

Hey Peter, I wonder if it is better to ask the user what type they would like to select and then have the input param inside the conditional. My concern about you approach is who it would interplay with workflows. Say you build a workflow that processes XML files with one input, say an XML file. If that input param had let you select multiple formats (format="tabular,xml"), then I believe the workflow input will as well even though the options as well, even though the workflow would not be valid for the other types. -John On Fri, Mar 15, 2013 at 9:43 AM, Peter Cock <p.j.a.cock@googlemail.com> wrote:

That is doable now, but I'm not sure it is optimal for usability.

Good point... I'm not sure what the workflow would currently allow here - just XML, or both tabular and XML.

I guess a side effect of my format specific options would be that a workflow using such a tool should be locked to just the one format.

Excellent point, I tend to be a pessimist about this sort of thing but you are indeed right and that would be a good solution. -John

Is that such a bad thing?
