A pure Python parser for working with MapServer MapFiles, built using Lark. mappyfile is an official OSGeo Community Project.

https://raw.githubusercontent.com/geographika/mappyfile/master/docs/images/OSGeo_community_small.png

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 https://mapserverstudio.net/. This will help to fund maintenance and further development of both mappyfile and MapServer.

Requirements

Python 3.8 or higher

Installation

mappyfile is available on PyPI (the Python Package Index), and can be installed using pip:

pip install mappyfile

This will also install its required dependencies - Lark, and jsonschema.

To install the optional lark-cython library for better performance on CPython you can run the following command:

pip install mappyfile[lark_cython]

mappyfile is also available on conda. Install as follows:

conda install -c conda-forge mappyfile

Usage

From within Python scripts:

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:

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
