That looks good John :)
I had considered something like your first hack using isinstance,
but much prefer your proposed $input.is_of_type(ext) solution :)

Fun question! I have opened a pull request with my answer -
https://bitbucket.org/galaxy/galaxy-central/pull-request/457/allow-cheetah-tool-templates-to-reason/diff.
There are three different hacks you can use right now... here is a
diff against tools/filters/catWrapper.xml I was using the to test them
- all of them require more about the internals of Galaxy then I really
think should be exposed to the tool (or tool author).

I think the last variant of this is what you want though
$input.is_of_type( ext ). You don't need to know the full module path
to the parent type - you are referring to it using the same extension
the rest of the tool uses and it doesn't require the use of $__app__
which... well we shouldn't be exposing to tools - it is not safe and
is a hindrance to ensuring backward compatibility.
Hope this helps.

[galaxy-dev] Determining datatype inheritance in tool XML Cheetah
Hi all,
I've just uploaded a simple sequence composition tool to the
Test Tool Shed:
https://testtoolshed.g2.bx.psu.edu/view/peterjc/seq_composition
https://github.com/peterjc/pico_galaxy/commit/45669446f5a14fd90a8a0d9d7430499de2fb3493
This accepts multiple input in FASTA, FASTQ, or SFF format -
and allows a mixture of these:
In order to build the command line string, I am currently using this
for loop:
seq_composition.py -o "$output_file"
##For loop over inputs
#for i in $input_file
--$i.ext "${i}"
#end for
This results in things like this being run:
seq_composition.py -o XXX.dat --fastqsanger XXX.dat --sff XXX.dat
This works, but means my Python script has to know about not just
the core data types that I specified in my input parameter XML
(fasta,fastq,sff) but also any subclasses (e.g. fastqsanger).
It seems what I want/need would be something along these lines
in pseudo-code to map any datatype which is a subclass for fastq
to use a single command line option:
seq_composition.py -o "$output_file"
##For loop over inputs
#for i in $input_file
#if isinstance($i.datatype, fastq):
--fastq "${i}"
#else
--$i.ext "${i}"
#end if
#end for
This mock example borrows from the Python isinstance function,
but of course some Galaxy datatypes are defined as subclasses
at the XML level rather than literally at the Python class level.
This should result in getting the following regardless of which
flavour of FASTQ the input dataset had assigned:
seq_composition.py -o XXX.dat --fastq XXX.dat --sff XXX.dat
Does anyone have any Tool XML examples probing an input file's
datatype in this way?
