Hi, I am a new galaxy developer playing with writing my first plugins
In my plugin xml configaration file: I want to be able to increase the value of one parameter based on another using
<command interpreter="python"> #if $rows.option =="header_ignore" #set $data_start = $rows.ignore + 1
but I get: unsupported operand type(s) for +: 'InputValueWrapper' and 'int'
A hack workaround I found was: #set $data_start = int(str($rows.ignore)) + 1
I just wondered if there was a cleaner way to get the integer value from a InputValueWrapper object.
That is exactly what I would have tried.
Probably with a little work on Galaxy we could get int($rows.ignore) to work too by defining an __int__ method on the InputValueWrapper class (see file lib/galaxy/tools/wrappers.py for details), but that would not work on older Galaxy installations which may or may not bother you?
Good idea Peter - I have opened a pull request here with this functionality:
https://github.com/galaxyproject/galaxy/pull/121
Christian - sorry I don't have a more clever workaround for this hack in the meantime.

Design wise, it would be nice if these wrapper classes offered more Python base object behaviour directly, but that is a design choice worth wider discussion?
Which is set to integer by:
<param name="ignore" size="4" type="integer" value="1" ....
If documentation exist somwere please send me an RTFM link. (I didn't find it in https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax)
Thanks in advance Christian Brenninkmeijer University of Manchester
