@cehbrecht @nilshempelmann Moving utilities from FP to eggshell brings a lot of changes and I've hit some issues. Since our test coverage is not so extensive, I'm expecting some breakage. One issue that has come up is the config file, which uses _PATH that is set relative to the file. If we import config from another package, a lot of things break. I haven't spent a lot of time on this, but maybe a config class with properties would solve the issue.

We advanced quite a bit on environment and config management in the last spring. Can't recall everything, but maybe updating doc on how it is done in PAVICS could help refactor FP and Eggshell.

Extensivation of tests is a good start

What's this long string of code in @nilshempelmann reply? The GitHub page itself?

[nilshempelmann]

Cleaned up now. Was replying from a mobile phone email

[tomLandry]

That's a bug in GitHub if you ask me. This code should never have make it to the thread input.

Just added a Path class to eggshell. https://github.com/bird-house/eggshell/blob/3929811bde32a249615356331b3f5b9ecf0aaa97/eggshell/config.py#L7

The idea is that you would do

from eggshell.config import Paths
import flyingpigeon

paths = Paths(flyingpigeon)
path.data
'/home/david/src/flyingpigeon/flyingpigeon/data'

So you may use the Paths class in any bird.

@huard: have a look on fp_dev branch in eggshell. What do you think about the structure?

[huard]

I don't see that branch...

[nilshempelmann]
