JSFS JSON Parser | Python Fiddle

#!/usr/bin/python

# created by Roman Plevka
# this script takes a path as an argument and outputs its structure as a valid JSON object
# currently used attributes: type (file|dir), name (String), size (Number) [, children (Array of Obj)]
# Change history:
# 2014-07-16 by Roman	created
# 2014-09-03 by Roman	algorithm (fixed for links - no more links following)
# 2014-09-09 by Roman	method (added extra parameters for specifying the output file)
#                     output (added extra attribute to the root level - date&time [dttm])
# 2014-09-29 by Roman algorithm (get real inode number)
# 2014-11-01 by Roman output (data wrapped in the root node)
# 2014-11-07 by Roman output (3rd argument implemented - "nofiles" - for output to ommit type:files)
# 2014-11-08 by Roman output (flag:all|nofiles added)
