Hi

By accident, my colleague found out, that we can use the $userEmail variable in the 'command' tag of the "tool config file", eg:

<command interpreter="perl">script.pl $input $userEmail $output </command>

Access to the 'user' information ('Anonymous' or the user's e-mail address if logged in) is very handy, as it gives the potential to execute the script differently depending on the value of $userEmail .

Now, we would like to use the 'user' information in order to create different options in the interface for the tool, eg:

<inputs> <param name="input" type="select" label="available files" display="radio" dynamic_options="ds_Options()"/> </inputs> <outputs> <data format="fasta" name="output"/> </outputs> <code file="more_code.py" />

where "ds_Options()" is defined in the extra python code "more_code.py"

I can pass a value to "ds_Options()" which we get as an example from a first page of the interface, eg:

<inputs> <page> <param name="dir" type="select" display="radio"> <option value="foo">FOO</option> <option value="bar">BAR</option> </param> </page> <page> <param name="input" type="select" label="available files" display="radio" dynamic_options="ds_Options(dir)"/> </page> </inputs> <outputs> <data format="fasta" name="output"/> </outputs> <code file="more_code.py" />

...but how do I pass just the 'user' information to the function?

As I can use '$userEmail' in the 'command' tag, I tried (with my limited understanding of galaxy and python) the obvious:

dynamic_options="ds_Options(userEmail)"

but I get

NameError: name 'userEmail' is not defined

Is there any way to pass the 'user' information?

Alternatively, is there a direct way to get access to the 'user' information within the function?

Thank you very much for your help
