Hi, Michael,

As others have said, in the long term, tool wrappers and their dependencies will be distributed and installed through tool sheds rather than being distributed with Galaxy source, so you might want to plan to generate and upload tool shed compatible archives from the get-go. The test and main tool sheds contain plenty of examples and Björn's tools exercise pretty much all of the functionality - you can browse the repo structure which is identical to the gz archive structure you need to upload to a new repo, or download the repo as a gz, unpack it and get exactly the kind of directory structure and contents you need to emulate for your tools. Once you have a working tool packaging the archive up is straightforward. 

The format for tool shed repo uploads and syntax for the tags used to define dependencies is very well documented in the tool shed section of the wiki. As Björn points out, the tool factory python wrapper might be a useful source of ideas and perhaps code. Your tool generator will need to do something similar to write the content and generate complete tool shed archives. When generating a new tool, the TF uses an ugly XML wrapper generator (contributed improvements would be very welcome!) and (probably more usefully) the few lines of code you need to package up the functional test data and the XML and wrapper if you need one in toolshed archive format.

Hi Michael,

I think you will enter new ground with your tool. The closest tool that
will do something similar is Ross toolfactory, I think:


For me one question is, do you really want to offer that service to
every user and is it save?

It is mainly a hg pull. But if you deinstall that repository and
reinstall it, all your files are lost.

I think that is a better way to do it. The API can be used to install
your tools. But it need to be configured beforehand from the user,

There is a feature request, that you can specify in your
toolshed-repository the preferred location in the tool panel. For now I
would ignore it and just install the tools somewhere and hope that
feature request is quiet high in Gregs ToDo list :)
