[gentoo-soc] Automatically generated overlay of R packages - progress report #6

["André Erdmann" <dywi@mailerd.de>]

Hi everyone,

== Brief summary of this project ==

The aim of this project is to create scripts that automate the process
of overlay creation/maintenance for R packages from repositories such
as CRAN and Bioconductor.

Longer:
For the ebuild creation of a single package one needs to extract the
package, copy-paste data from its description file to the ebuild and
look up dependencies, which is time-consuming.
Although trivial for a few number of packages, this is practically
impossible to do by hand for repositories like CRAN (> 3500 packages),
especially 'cause it also requires tracking changes (new / updated /
removed packages).
The solution is to automate that process and this is what this project is about.

== Progress of this week ==

* added remote syncing (via rsync) and the possibility to use local
directories for overlay creation

* added some dependency resolution logic: 'R (>= 2.15)' is now
recognized as '>=dev-lang/R-2.15' etc.

* did a first test run (creating ebuilds for CRAN) and fixed some
issues like illegal ebuild names ("AMAP.Seq" etc.)

I'm on schedule.

== Plans for the next week ==

* do more testing
* write a main script
