configreader 0.0.6

Usage

As a simple example of what is possible and how to use the module, see the following config file which is by the way completely valid python:

home = os.getenv('HOME')
aster_root = home+"/data/opt/aster"
project = "bikeframe-test"
version = "testing"
# source directory for all files if relative path
srcdir = "."
# output directory for all stuff
outdir = "results"
# input mesh file
meshfile = "mesh.med"
logfile = "asterclient.log"
workdir = "/data/tmp"
# define the studies
calculations = [
    {"name":"main",
      "commandfile": "main.comm",
      "resultfiles":{
            "bikeframe.rmed":80,
            "bikeframe.msh": 81,
            "buckling.rmed": 82,
            "bikeframe.table": 39,
            "bikeframe.resu": 38,
            "buckling.resu": 37,
            },
      "inputfiles":["parameters.py"],
      },
    {"name": "post",
      "commandfile":"post.comm",
      "poursuite": "main",
      "resultfiles":{
        "vmises.table": 40,
        "protocol": "protocol*.rst",
        }
      }]

Suppose we have this saved as profile.conf we could read it like:

import os
from configreader import Config

c = Config(open('profile.conf','r'),namespace={'os.getenv':os.getenv})

which would give as all the values specified and evaluated as a python dict. If we wouldn’t have provided the namespace with os.getenv the parsing would have failed since it only allows functions mapped in the namespace, so you have completele fine grained possibility on what to allow. As input the Config class expects any file like object which is an object with a read method.

Testing

There are a few simple test cases in tests use best py.test to run them.
