Hi Evan,

Yes, it is possible. Please note that these will not/may not work in workflows as expected and the use of code files is generally discouraged. (That said, in some cases you care more about user experience than anything else, and here they are useful.)

Here's an example from my Apollo tool suite which lets the user interact with a service that lives outside of Galaxy. The user is able to select from a dropdown which dataset they would like to retrieve from that system (filtering on ones that they have permissions for.)

Here I define an input with a dynamic_options parameter: https://github.com/galaxy-genome-annotation/galaxy-tools/blob/master/tools/a...

I specify at the top of my tool which code file I want to load: https://github.com/galaxy-genome-annotation/galaxy-tools/blob/master/tools/a...

Now when this is accessed, it looks at the code file paramater and calls the appropriate function: (There's a bit of unrelated stuff going on in here to handle caching since those calls are called many times and my backend is slow) https://github.com/galaxy-genome-annotation/galaxy-tools/blob/master/tools/a...

Eventually this is called whcih shows the expected return format: https://github.com/galaxy-genome-annotation/galaxy-tools/blob/master/tools/a... A list of tuples where the first parameter is what the user sees, the second parameter is what value the option has (that is passed on the command line), and the third is "False".

Cheers,

Hi all, this would help in a tool I’m trying to write too but the problem I have implementing this approach is that my script will need an external python module - is there any way that I can list dependencies for the script? As it happens these are the same dependancies that the tool itself will need once executed.

Thanks,

Steve

Yes, this is possible with "dynamic_options"

e.g.:

<tool ...

<inputs>

<param name="year" type="select" label="from which year" display="radio" refresh_on_change="true" > <option value="/2017" selected="true">2017</option> <option value="/2016">2016</option> <option value="/2015">2015</option> </param>

<param name="file" type="select" label="select a run" display="radio" dynamic_options="ds_readFiles(year)"/>

</inputs> <outputs> ... </outputs> <help> ... </help> <code file="more_code.py" />

</tool>

The python function "ds_readFiles" is defined in a extra code file "more_code.py", which is stored in the same directory as the tool definition file. The function returns all files with a matching file name (i.e.year), and could look like:

rDir = "/data/"

def ds_readFiles(year):

l = os.listdir(rDir) p = re.compile('^%s_[0­9]{4}_M[0­9]{5}_[0­9]'%year) l.sort() path = rDir filesoptions = [(s) for s in l if os.path.exists(path + s)] files = [(s,s,False) for s in filesoptions if p.match(s)] return files

a similar case is also described here:

I could do that but it would mean that no-one could install the tool from the toolshed without also installing this package.

Maybe I just need to hack this together.

I don’t like ‘hacks’!! I solved this by pulling the relevant bits of the module into my script so that it runs with no dependencies. It’s basically just making an HTTP GET request with an authentication header, so not too hard to achieve. Should be safe to put in the toolshed.

Thanks, this is a big improvement in our UI (and I vote for not deprecating this feature, maybe even making it more robust).

Sure

However, tools relying on "dynamic_options" and extra "code" scripts are usually 'hacks' for accessing external data/services in a local galaxy installation. And such tools are not intended for the toolshed anyway....IMHO.
