we need a smart solution for wrappers

[meren]

I am all for wrappers, but currently we use them at one place, and we need to copy the wrappers directory to a relative location to the snakemake file. I think this is not very feasible, and we need to find a better way to handle wrappers.

This is how I'm running things at the moment:

Meren, don't take this to think that I'm working ;-) But shouldn't we aspire to use the official snakemake wrapper repository? And then we don't need people to put the wrappers in a specific place.

Hey Alon,

I just wanted to leave something behind so we remember it later :) What are YOU doing here!?

But shouldn't we aspire to use the official snakemake wrapper repository?

Absolutely. But this shouldn't stop us from testing and using our stuff effectively and without pain. We can find a way to make this process seamless. I.e, if a wrapper is in the official repository the code would use it from there, if not, the code would set some environmental variables to use them from whatever location on the disk we keep them. Having to copy a directory to run a snakemake file is what is not working :)

I will ask @ozcan's opinion on this during the week.
