jarg 0.4.1

jarg is an encoding shorthand for your shell.
It is a command-line utility that makes generating data in formats like JSON, YAML, and form encoding easier in the shell.

Installation
Install from PyPI:
$ pip install jarg

Usage
Each argument to jarg should be in the format of name=value.
Values are interpreted as their closest native encoding value, and the default dialect is JSON.
The most common case is probably string names and values:
$ jarg foo=bar baz=quux
{"foo": "bar", "baz": "quux"}
Floats and integers will work too:
$ jarg foo=10 bar=4.2
{"foo": 10, "bar": 4.2}
The value is optional.
If you leave it out, it is interpreted as null:
$ jarg foo
{"foo": null}
The name portions have the same syntax and semantics as HTML JSON names:
$ jarg foo[]=bar foo[]=baz bar[baz]=quux
{"foo": ["bar", "baz"], "bar": {"baz": "quux"}}
You can also write literal values directly, using the name:=value syntax.
That lets you write things like booleans, lists, and explicit strings:
$ jarg foo:=true bar:=\"123\"
{"foo": true, "bar": "123"}
$ jarg foo:=[1,2,3]
{"foo": [1, 2, 3]}

Dialects
The default dialect is JSON, and includes support for YAML and form encoding.
To use the YAML dialect, use the -y/--yaml switch:
$ jarg -y name=jarg type="cli tool" traits[]=dope traits[]=rad
---
name: jarg
traits: [dope, rad]
type: cli tool
You can switch to the form encoding dialect with the -f/--form switch:
$ jarg -f foo=bar baz="jarg is dope"
foo=bar&baz=jarg+is+dope
