Re: [galaxy-dev] Getting tool dirpath in a Python code file
Hi Leandro, Leandro Hermida wrote, On 04/29/2011 06:17 AM: But I have one complication I guess. My tool is already running a Python code file to dynamically create a drop-down menu using the dynamic_options attribute a la: param type=select dynamic_options=my_options() ... code file=my_options.py/ In this function my_options I would need the tool dir path. How would I be able to combine what you did with this? Which function runs at the right time before my_options() is executed is it exec_before_process? This just gets messier and messier :) The following hack will get you the tool's path inside the dynamic option code, but it is SO ugly, I would highly recommend against it. A better way would be to add some code to ./galaxy/lib/parameters/basic.py inside get_options() to add the 'tool' object to the other_values object, so that custom code functions would be able to access it (or something similar and as clean). That being said, here goes: = dynamic_options_path.xml == tool id=cshl_dynamic_optinos_path_test name=dynamic_options_path description= commandecho '$input1' gt; '$output'/command inputs param name=input1 type=text value=10 label=Dummy/ param name=mylist type=select label=Dynamic Options dynamic_options=get_my_options(code_ref=get_my_options) display=radio / /inputs code file=dynamic_options_code.py / outputs data name=output format=txt / /outputs /tool === == dynamic_options_code.py == import os import os.path import sys def get_my_options(code_ref): root_dir=os.getcwd() sys.stderr.write(Galaxy root dir = %s\n % ( root_dir ) ) sys.stderr.write(Custom code file = %s\n % ( code_ref.__code__.co_filename) ) tool_path = root_dir + '/' + os.path.dirname( code_ref.__code__.co_filename) sys.stderr.write(tool path = %s\n % ( tool_path ) ) res = [('Hello','World',False),] return res == The output (STDERR) when viewing the tool's form is: Galaxy root dir = /home/gordon/projects/galaxy_dev Custom code file = ./tools/cshl_tests/dynamic_options_code.py tool path = /home/gordon/projects/galaxy_dev/./tools/cshl_tests The trick is that the dynamic function itself (get_my_options()) is a valid object (which is luckily accessible from inside the code), and python keeps track of the file that contained the function. Good luck (and don't try this at home :) ), -gordon ___ Please keep all replies on the list by using reply all in your mail client.

Re: [galaxy-dev] Getting tool dirpath in a Python code file
Hi galaxy developers, Just want to double-check, there is no way to import some kind of galaxy tool context info into python code you are running for a tool? best, leandro On Fri, Apr 15, 2011 at 8:03 PM, Leandro Hermida soft...@leandrohermida.com wrote: On Fri, Apr 15, 2011 at 7:27 PM, Peter Cock p.j.a.c...@googlemail.comwrote: On Thu, Apr 14, 2011 at 2:56 PM, Leandro Hermida soft...@leandrohermida.com wrote: On Thu, Apr 14, 2011 at 3:17 PM, Peter Cock p.j.a.c...@googlemail.com wrote: For standard Python tools in Galaxy, I'm using os.path.split(sys.argv[0])[0] to get the path, which on reflection probably should be written as os.path.dirname(sys.argv[0]) as you suggest.
