jgrepl 0.1.5

# json-graph-repl
Extensible command-line REPL for interacting with JSON graphs containing business objects.

The JSON format is based on the `json-graph` specification at: https://github.com/jsongraph/json-graph-specification

Several additional assumptions are made:

* We assume that the graph contains no cycles
* We treat node IDs as case-insensitive
* There are certain `metadata` fields that some aspects of the tool depend on (but none of these are mandatory)

Sample graphs are provided in the `tests` directory.

To use from the command line, just point the `jgrepl` tool to your JSON graph:

$ ./jgrepl/jgrepl.py tests/food-graph.json

Once in the REPL, type `help` for the list of available commands. Use `ctrl-d` to exit.

Here is a sample session using the "food" graph:

*** Loading graph from 'tests/food-graph.json'...
