jsonxs 0.3

Examples

Given the folowing datastructure:

d = {
  'feed': {
    'id': 'my_feed',
    'url': 'http://example.com/feed.rss',
    'tags': ['devel', 'example', 'python'],
    'short.desc': 'A feed',
  }
}

We can get, set and delete values from the stucture.

jsonxs(d, 'feed.id')                                  # Get the 'id' field: 'my_feed'
jsonxs(d, 'feed.tags')                                # Get the list of tags.
jsonxs(d, 'feed.tags[-1]')                            # Get the last item in the 'tags' list: 'python'
jsonxs(d, 'feed.short\.desc')                         # Escape special char
jsonxs(d, 'feed.long\.desc', default='N/A')           # Return default when key not found
jsonxs(d, 'feed.id', ACTION_SET, 'your_feed')         # Set feed id to 'your_feed'
jsonxs(d, 'feed.tags[-1]', ACTION_SET, 'javascript')  # Replace 'python' with 'javascript'
jsonxs(d, 'feed.tags[0]', ACTION_DEL)                 # Delete the first tag
jsonxs(d, 'feed.url', ACTION_DEL)                     # Delete the 'url' key from a dict
jsonxs(d, 'feed.tags', ACTION_APPEND, 'programming')  # Append 'programming' to tags
jsonxs(d, 'feed.tags[1]', ACTION_INSERT, 'tech')      # Insert 'tech' at pos 1 in tags
jsonxs(d, 'feed.author', ACTION_SET, 'Ferry Boender') # Create new key/string value in dict
jsonxs(d, 'feed.details', ACTION_MKDICT)              # Create new key/dict value in dict
jsonxs(d, 'feed.details', ACTION_MKLIST)              # Create new key/list value in dict
