Re: [galaxy-dev] datatype dependencies
My understanding of the code is that tool shed dependencies (or local dependencies) will not be available to tool shed datatypes (for sniffing for instance). Sorry. If you want to hack up your local instance to resolve dependencies during the sniffing process that may be possible - my guess is you could add requirement tags to tools/data_source/upload.xml and the __SET_METADATA__ tool definition embedded in lib/galaxy/datatypes/registry.py - though I have not tried this. -John On Thu, Jul 17, 2014 at 2:24 PM, Peter Cock p.j.a.c...@googlemail.com wrote: On Thu, Jul 17, 2014 at 8:20 PM, Eric Rasche rasche.e...@yandex.ru wrote: On 07/17/2014 02:11 PM, Peter Cock wrote: You could do something like that, and we already have Biopython packages in the ToolShed which can be listed as dependencies :) If my module depends on the biopython from the toolshed, will that be accessible within a datatype?
