A pure Python parser for working with MapServer MapFiles, built using Lark

An online formatter demonstrating the libraries capabilities can be found at: http://mappyfile.geographika.net/

A presentation on mappyfile was given at FOSS4G Europe 2017 - slides are available for download here.

Requirements

  • Python 2.7 or Python 3.x

Installation

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

pip install mappyfile

This will also install its required dependences Lark (lark-parser), and jsonschema.

Documentation

Full documentation is available at http://mappyfile.readthedocs.io/en/latest/

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"))

Two command line tools are available - format and validate:

mappyfile format raster.map formatted_raster.map
mappyfile validate D:\ms-ogc-workshop\ms4w\apps\ms-ogc-workshop\**\*.map
