A possible implementation of path_config.py to quickly get path configuration in all subsites of our typical iktomi-based project. This module is placed in code root and symlinked to all subsite roots. A script in subsite root requires just the following single line: import path_config

path_config.py

import os, sys, warnings

def _get_root():
    # Only .py file is symbolic link, while compiled module can be placed
    # locally
    name, ext = os.path.splitext(__file__)
    fn = os.path.abspath(name +'.py')
    if os.path.islink(fn):
        # Symlinks are relative to target, not working dir
        fn = os.path.join(os.path.dirname(fn), os.readlink(fn))
        fn = os.path.abspath(fn)
    return os.path.dirname(fn)

ROOT = _get_root()

sys.path.insert(0, os.path.join(ROOT, 'third-party'))

warnings.simplefilter('error')
