Project Description

hipack is a Python module to work with the HiPack serialization format. The API is intentionally similar to that of the standard json and pickle modules.

Features:

  • Both reading, and writing HiPack version 1 is supported. The following extensions are implemented as well:

    (Note that extensions defined in HEPs are subject to change while they are being discussed as proposals.)

  • Small, self-contained, pure Python implementation.

  • Compatible with both Python 2.6 (or newer), and 3.2 (or newer).

Usage

Given the following input file:

# Configuration file for SuperFooBar v3000
interface {
  language: "en_US"
  panes {
    top: ["menu", "toolbar"]  # Optional commas in lists
    # The colon separating keys and values is optional
    bottom
      ["statusbar"]
  }
  ☺ : True  # Enables emoji
  Unicode→Suþþorteð? : "Indeed, Jürgen!"
}

# Configure plug-ins
plugin: {
  preview  # Whitespace is mostly ignored
  {
    enabled: true
    timeout: 500  # Update every 500ms
  }
}

Note that the : separator in between keys and values is optional, and can be omitted. Also, notice how white space —including new lines— are completely meaningless and the structure is determined using only braces and brackets. Last but not least, a valid key is any Unicode character sequence which does not include white space or a colon.

The following code can be used to read it into a Python dictionary:

import hipack
with open("superfoobar3000.conf", "rb") as f:
  config = hipack.load(f)

Conversions work as expected:

  • Sections are converted into dictionaries.
  • Keys are converted conveted to strings.
  • Text in double quotes are converted to strings.
  • Sections enclosed into { } are converted to dictionaries.
  • Arrays enclosed into [ ] are converted to lists.
  • Numbers are converted either to int or float, whichever is more appropriate.
  • Boolean values are converted to bool.

The following can be used to convert a Python dictionary into its textual representation:

users = {
  "peter": {
    "uid": 1000,
    "name": "Peter Jøglund",
    "groups": ["wheel", "peter"],
  },
  "root": {
    "uid": 0,
    "groups": ["root"],
  }
}

import hipack
text = hipack.dumps(users)

When generating a textual representation, the keys of each dictionary will be sorted, to guarantee that the generated output is stable. The dictionary from the previous snippet would be written in text form as follows:

peter: {
  name: "Peter Jøglund"
  groups: ["wheel" "peter"]
  uid: 1000
}
root: {
  groups: ["root"]
  uid: 0
}

Installation

The stable releases are uploaded to PyPI, so you can install them and upgrade using pip:

pip install hipack

Alternatively, you can install development versions —at your own risk— directly from the Git repository:

pip install -e git://github.com/aperezdc/hipack-python

Development

If you want to contribute, please use the usual GitHub workflow:

  1. Clone the repository.
  2. Hack on your clone.
  3. Send a pull request for review.

If you do not have programming skills, you can still contribute by reporting issues that you may encounter.
