CartoCSS documentation Python parser.

Install

pip install cartocss-doc-parser

Quickstart

The main function cartocss_doc returns a dictionary with almost every section of the documentation. All the properties are wrapped in generators.

>>> from pprint import pprint
>>> from cartocss_doc_parser import cartocss_doc
>>>
>>> doc = cartocss_doc()
>>> pprint(doc)
{'building': <generator object ...>,
 'common_elements': <generator object ...>,
 'line': <generator object ...>,
 'line_pattern': <generator object ...>,
 'map_background_and_string_elements': <generator object ...>,
 'markers': <generator object ...>,
 'other_parameters': <generator object ...>,
 'point': <generator object ...>,
 'polygon': <generator object ...>,
 'polygon_pattern': <generator object ...>,
 'raster': <generator object ...>,
 'shield': <generator object ...>,
 'symbolizers': <generator object ...>,
 'text': <generator object ...>,
 'torque_properties': <generator object ...>,
 'values': <generator object ...>}

All properties contains the attributes

• default Default value.
• description Description.
• id Identificator.
• link Link to the property on documentation.
• name Name of the property.
• sample Example of use.
• type Value data type. For a complete list see cartocss_data_types.

and if the data type is keyword contains an additional attribute

• variants Possible values for the property.

>>> pprint(list(doc["polygon"]))
[{'default': 'gray',
  'description': 'The fill color assigned to a polygon.',
  'id': 'polygon-fill-color',
  'link': 'https://carto.com/developers/styling/cartocss/#polygon-fill-color',

  'sample': 'polygon-fill: rgba(128, 128, 128, 1);',
  'type': 'color'},
 {'default': '1',
  'description': 'The opacity of the polygon.',
  'id': 'polygon-opacity-float',
  'link': 'https://carto.com/developers/styling/cartocss/#polygon-opacity-float',
  'name': 'polygon-opacity',
  'sample': 'polygon-opacity: 1;',
  'type': 'float'},
 ...,
 {'default': 'power',
  'description': 'An anti-grain geometry method that represents a 2D rendering '
                 'library, specific to controlling the quality of antialiasing '
                 'and used to calculate pixel gamma (pow(x,gamma), which '
                 'produces slightly smoother line and polygon antialiasing '
                 "than the 'linear' method.",
  'id': 'polygon-gamma-method-keyword',
  'link': 'https://carto.com/developers/styling/cartocss/#polygon-gamma-method-keyword',
  'name': 'polygon-gamma-method',
  'sample': 'polygon-gamma-method: power;',
  'type': 'keyword',
  'variants': ['power', 'linear', 'none', 'threshold', 'multiply']},
 ...
]

All data types can be requested with cartocss_data_types function:

>>> pprint(list(cartocss_data_types()))
['color',
 'float',
 'uri',
 'string',
 'boolean',
 'expression',
 'numbers',
 'number',
 'percentages',
 'percentage',
