A (python) indexer for large collections of json files

Project description

A (python) indexer for large collections of json files. In development and probably not good for general use yet.

Installation

pip install JsonPydexer

Usage

Starting from zero

>>>from JsonPydexer import JsonPydexer
>>># initialize with the root directory containing your json files
>>>jp = JsonPydexer("test_data/3")
>>># index on your keys. provide a list of keynamess. keyname elements can be a string for a
>>># field at root level, or a list of strings for nested fields
>>>jp.index(["id", "name", ["field_in_root", "field_below"]])

Opening an existing index

>>># initialize with the root directory containing your json files and .jp.pkl
>>>jp = JsonPydexer("test_data/3")
>>># get all the files that match a search string for non-unique index
>>>search_string = "alice"
>>>for filename in jp.get_files(["name"], search_string):
>>>    print(filename)
1.json
3.json
>>># get the file matching a search string for a unique index
>>>filename = jp.get_file(["id"], "id2")
>>>print(filename)
2.json

Added, removed, or modified JSON files? Update the index

>>>jp = JsonPydexer("test_data/3")
>>>jp.update()

New files in the directory will be added to the index. Coming soon are: removing files not present in the directory from the index, and checking for modified files in the directory.
