json-templates

A small python module for populating json template files.

Version 0.1.0

Accepts either a json string or a file path and a dictionary. json-template replaces the place holders found in the json with those found in the dictionary.

Below is a template example

{
  "key":"hard coded value",
  "key2":1,
  "key3":"{{ variable }}",
  "key4":"{% array %}"
}

Currently supports {{ variable }} for single replacement and {% array %} for iterable replacement.

For example given the following dictionary

{
  "variable":"hello world",
  "array":["foo","bar"]
}

The JSON would become

{
  "key":"hard coded value",
  "key2":1,
  "key3":"hello world",
  "key4":["foo","bar"]
}

Usage

import JsonTemplates

json_tmp = JsonTemplates()
result = json_tmp.load("template.json")

if result[0]:
  new_dict = json_tmp.generate({"variable":"hello world","array":["foo","bar"]})
