mappyfile is used for formatting and validation in https://app.mapserverstudio.net/, and can be tested for free on any
of your Mapfiles. If you find mappyfile useful please consider signing up for a professional account at

Requirements
------------

* Python 3.8 or higher

Installation
------------

mappyfile is available on `PyPI <https://pypi.org/project/mappyfile/>`_ (the Python Package Index), and can be installed using pip:

.. code-block:: console

    pip install mappyfile

`jsonschema <https://github.com/python-jsonschema/jsonschema>`_. 

To install the optional `lark-cython <https://github.com/lark-parser/lark_cython>`_ library
for better performance on CPython you can run the following command:

.. code-block:: console

    pip install mappyfile[lark_cython]

Usage
-----

From within Python scripts:

.. code-block:: python

    import mappyfile

    mapfile = mappyfile.open("./docs/examples/raster.map")
    
    # update the map name
    mapfile["name"] = "MyNewMap"

    new_layer_string = """
    LAYER
        NAME 'land'
        TYPE POLYGON
        DATA '../data/vector/naturalearth/ne_110m_land'
        CLASS
            STYLE
                COLOR 107 208 107
                OUTLINECOLOR 2 2 2
                WIDTH 1
            END
        END
    END
    """

    layers = mapfile["layers"]

    new_layer = mappyfile.loads(new_layer_string)

    layers.insert(0, new_layer) # insert the new layer at any index in the Mapfile

    for l in layers:
        print("{} {}".format(l["name"], l["type"]))

    print(mappyfile.dumps(mapfile, indent=1, spacer="\t"))

Three command line tools are available - ``format``, ``validate``, and ``schema``:

.. code-block:: bat

    mappyfile format raster.map formatted_raster.map
    mappyfile validate D:\ms-ogc-workshop\ms4w\apps\ms-ogc-workshop\**\*.map
    mappyfile schema mapfile-schema-8-0.json --version=8.0
