#
# This file is designed to convert a very big (complete?) list of plant
# genera (from theplantlist.org) from "comma separated values" format into
# json format. This will result in the file becoming much bigger, because 
# the property names are stored for every object in the json format eg:
#    [ 
#        { "family": "Myrtaceae", 
#          "genus": "Eucalyptus" }
#         ...
#    ]
#
# Whereas, in the csv format the property names are stored, only once, at
# the top of the file.
#
# This effort is part of the earthtree ios swift app which is 
# designed to display and map trees in the entire world! one by one!
#
# I will use the "Codable" swift protocol to convert the json data
# to swift objects, and the UITableViews, MapKits etc to display it and 
# hopefully, to edit it, add to it. 
#
# Usage:
#   python csvtojson.genera.py > plant.genera.all.json
#
# Remember to remove the last comma in the generated file !!!! That 
# extra comma will make the swift Codable encoder not work.
#
# History:
#  3 July 2019
#    began to adapt this script from the very similar one "csvtojson.opentrees.py"
