pip install pgformat

Usage

The package comes with a simple command line client to convert between serialization forms of Property Graph Exchange format and an API to be used in python code. The command line client by default reads PG Format and emits PG JSONL.

usage: pgformat [-h] [-t {ndjson,json,pg}] [source]

Parse and transform property graphs in PG Format.

positional arguments:
  source                input file (default: - for standard input)

options:
  -h, --help            show this help message and exit
  -t {ndjson,json,pg}, --to {ndjson,json,pg}
                        target format

The functionality is a subset of the pgraph command line tool written in NodeJS.

The command line client can also be called via python -m pgformat.

API

The package exports two functions: parseGraph and parseStatements:

from pgformat import parseGraph, parseStatements

graph = parseGraph("a -> b")
statements = parseStatements("x\na -> b")

The return format consists of plain lists and arrays for direct conversion to JSON.
