jmespath-terminal 0.1.1

Overview

JMESPath is an expression language for manipulating JSON documents. If you’ve never heard of JMESPath before, you write a JMESPath expression that when applied to an input JSON document will produces an output JSON document based on the expression you’ve provided.

You can check out the JMESPath site for more information.

One of the best ways to learn the JMESPath language is to experiment by creating your own JMESPath expressions. The JMESPath Terminal makes it easy to see the results of your JMESPath expressions immediately as you type.

Getting Started

You can install the JMESPath Terminal via pip:

$ pip install jmespath-term

There will then be a jpterm program you can run:

$ jpterm

With no arguments specified, a sample JSON document is used as input.

You can also specify an initial JSON document to use by specifying the JSON file as a positional argument:

$ jpterm /tmp/somejsondoc.json

You can also pipe an input JSON document into the jpterm command:

To quit the program, press F5. You can also clear the current expression by specifying Ctrl + ].

Working on JMESPath Terminal

If you like to work on jmespath-terminal to add new features, you can first create and activate a new virtual environment:

$ virtualenv venv
$ . venv/bin/activate

Then install the module:

$ pip install -e .

You’ll now be able to modify the jpterm.py module and see your changes reflected when you run the jpterm command.

Beta Status

Until jmespath-terminal reaches version 1.0, some of the command line options and semantics may change. There will be a CHANGELOG.rst that will outline any changes that occur for each new version.
