To use Puritan, you need to install dependencies:

 # NB: mock >= 0.9.7 is needed.
 # debian:
 sudo apt-get install mock git-core
 # fedora:
 sudo yum install mock git-core
 # both
 sudo usermod -a -G mock $USER
 newgrp mock

and to check out and run a 'ui' and a 'compilation'.

 (git clone git://dev.laptop.org/users/mstone/puritan compilation; cd compilation; git branch --track 767 origin/767; git checkout 767)
 git clone git://dev.laptop.org/users/mstone/puritan ui
 python2.5 ui/puritan/main.py   # read help
 sudo python2.5 ui/puritan/main.py -v build ./compilation HEAD ./results -- -i

Interactive Debugging

The '-i' option above enables an interactive error-handling mode. If an error occurs,

with the most recent compilation and ui, you will be dropped directly into bash inside the buildroot.

  • to resume the compilation, type
 exit 0
  • to quit the compilation, type
 exit 1

with earlier compilations which still support interactive error-handling: instructions

  • to learn what command failed:
  • to get a bash shell inside the buildroot for further debugging
 import os
  • to resume the compilation after fixing an error:
 del kwargs['e']
  • to exit the compilation and clean up.

Other Notes


Note: if you encounter permission errors when running this command, you may need to:

 sudo setenforce 0  # disable selinux

Note: a word of warning: while _my_ uis and compilations will treat your computer nicely, other people's might not. Caveat emptor.


mock_0.9.7-2 on ubuntu requires [1] in order to run. Additionally, if you run puritan as root, you should either

usermod -a -G mock -u $SUDO_UID
unset SUDO_UID  # or

Some puritan compilations now feature a 'download' operation which can be used to download all packages that the compilation will install for later (offline) use:

 sudo python2.5 ui/puritan/main.py -v download ./compilation HEAD ./results 

This command will generate a program in the results directory which can be used to download the packages.
