The small amount of code that generates the *.eb could be in Python and hence that could go in the easyblock, but the majority of the code is R based on Stefano's script to generate the list of R packages their versions & the repos they came from and then re-order the list based on the dependencies. I would not know how to accomplish this without using R's own dependency handling mechanism and AFAIK their is no way to do this in Python. So the best I can imagine for now is a modified R easyblock that can execute an external R script to create a pkglist... and then generate an updated easyconfig. > We currently don't have a good location for this; I don't think we should > start adding 'random' scripts to the easyconfigs repo... The .../r/R/ dir in the EasyConfigs repo would be the first place where I would look for examples and a way to create new updated R easyconfigs, so in that sense it isn't a random location, but I agree that it is random in the sense that it isn't EasyBuild style Python code and R specific. Preferably we would not need a kludge like this :o > Maybe go with https://github.com/fgeorgatos/easybuild.experimental for now to > share it with others? That looks like a good place to start, so we can have a first version of an pure R easyconfig generator by the end of this week... > We should look into a contrib directory in the main EasyBuild repo > (https://github.com/hpcugent/easybuild), where people can get stuff included > without too much reviewing or very strict requirements, we already have a > couple of PRs for stuff like that (see > https://github.com/hpcugent/easybuild-framework/pull/1190, > https://github.com/hpcugent/easybuild-framework/pull/1180). Check, let me know when there is a contrib dir in place.
