How to run Python Linux commands in PyPy ?

I have been using PyPy from 1.6. Now PyPy 2.0beta1 is out. Most of python libraries which don’t have c extensions as dependencies work(exceptions are present).

E.g: requests, fabric, gunicorn

Install PyPy2.0beta1

1. Grab 32 or 64 bit pypy2.0 beta1. If you are using ubuntu grab libc2.5.

`` bzip2 pypy-2.0-beta1-linux64-libc2.15.tar.bz2 ``

`` tar -xvf pypy-2.0-beta1-linux64-libc2.15.tar ``

<code>curl -O <a href="http://python-distribute.org/distribute_setup.py" target="_blank">http://python-distribute.org/distribute_setup.py</a></code>

<code>curl -O <a href="https://raw.github.com/pypa/pip/master/contrib/get-pip.py" target="_blank">https://raw.github.com/pypa/pip/master/contrib/get-pip.py</a></code>

`` ./pypy-2.0-beta1/bin/pypy distribute_setup.py ``

`` ./pypy-2.0-beta1/bin/pypy get-pip.py ``

`` ./pypy-2.0-beta1/bin/pip install virtualenv ``

Please feel free to create `` alias ``. Here is sample alias.



alias pypy2b="/home/kracekumar/downloads/pypy-2.0-beta1/bin/pypy"
alias pypy2b-pip='/home/kracekumar/downloads/pypy-2.0-beta1/bin/pip'
alias pypy2b-venv='/home/kracekumar/downloads/pypy-2.0-beta1/bin/virtualenv'

Next ?

1. pypy2b-pip install fabric

2. Add pypy bin directory to $PATH, export PATH=$PATH:/home/kracekumar/downloads/pypy-2.0-beta1/bin or open ~/.bashrc add export PATH=$PATH:/home/kracekumar/downloads/pypy-2.0-beta1/bin and source ~/.bashrc.

    kracekumar@aadukalam:~/codes/python-wiktionary$ which fab
    /home/kracekumar/downloads/pypy-2.0-beta1/bin/fab

4. 
kracekumar@aadukalam:~/codes/python-wiktionary$ cat which fab
#!/home/kracekumar/downloads/pypy-2.0-beta1/bin/pypy
# EASY-INSTALL-ENTRY-SCRIPT: ‘Fabric==1.5.1’,‘console_scripts’,‘fab’
requires = ‘Fabric==1.5.1’
import sys
from pkg_resources import load_entry_point
if name == ’main’:
sys.exit( load_entry_point(‘Fabric==1.5.1’, ‘console_scripts’, ‘fab’)()
)

So fab now uses pypy interpreter rather than CPython.

But there are other commands like history, gwibber-service which are installed via apt-get can’t use PyPy since apt-get doesn’t support pypy since it is unstable.

Thoughts

• There should be way developer can specify in debian/ubuntu repo to look for PyPy in the user installation if not use CPython.

• apt-get is written in python, if distros ship pypy and apt-get works well, there is a chance PyPy will became main stream in linux packaging.
