Python Mini Racer

image

Minimal, modern embedded V8 for Python.

  • Free software: ISC license

image

Features

  • Unicode support
  • Thread safe
  • Re-usable contexts
  • Binary object is Python agnostic

MiniRacer can be easily used by Django or Flask projects to minify assets, run babel or compile CoffeeScript.

Examples

py_mini_racer is straightforward to use:

>>> from py_mini_racer import py_mini_racer
>>> ctx = py_mini_racer.MiniRacer()
>>> ctx.eval('1+1')
2
>>> ctx.eval("var x = {company: 'Sqreen'}; x.company")
u'Sqreen'
>>> print ctx.eval(u"'\N{HEAVY BLACK HEART}'")
❤
>>> ctx.eval("var fun = () => ({ foo: 1 });")
>>> ctx.call("fun")
{u'foo': 1}

Variables are kept inside of a context:

>>> ctx.eval("x.company")
u'Sqreen'
[1,2,3].map(n => n + 1);

Compatibility

PyMiniRacer is only compatible with Python 2.7 at the moment. Python 3 support is on its way.

Binary builds availability

The PyMiniRacer binary builds have been tested on x86_64 with:

  • OSX 10.11
  • Ubuntu >= 14.04
  • Debian >= 8
  • CentOS >= 7

You need pip >= 8.1 to install the wheels - you can check and upgrade yours in this way:

$ pip --version
$ pip install --upgrade pip

It should work on any Linux with a libc >= 2.17 and a wheel compatible pip (>= 8.1).

Installation

We built Python wheels (prebuilt binaries) for OSX 64 bits and Linux 64 bits -most recent distributions. You need pip >= 1.4 and setuptools >= 0.8.

$ pip install py-mini-racer

Build

You can build v8 with the command:

$ python setup.py build_v8

You can also build the ctype extension:

$ python setup.py build_ext

Which automatically builds v8.

You can generate a wheel with the command:

$ python setup.py bdist_wheel

which builds v8, the extension, and generates a wheel.

Tests

If you want to run the tests, you need to build V8 first, then launch:

$ python setup.py test --addopts tests

Credits

Built with love by Sqreen.

PyMiniRacer launch was described in this blog post.

PyMiniRacer is inspired by mini_racer, built for the Ruby world by Sam Saffron.

Tools used in rendering this package:

Todo

Lower libc version needed. Export V8 version. Fix circular structures export.
