A collection of common pynt tasks

Raghunandan Rao

pynt-contrib has a collection of tasks and utilities for pynt. pynt-contrib allows pynt itself to continue to be simple, while enhancing it.

Installation

You can install pynt-contrib from the Python Package Index (PyPI) using pip (pip install pynt-contrib) or easy_install (easy_install pynt-contrib), or from source (python setup.py install)

Example

build.py

#!/usr/bin/python
from pynt import task
from pyntcontrib import safe_cd, execute

#TODO: write this up
@task()
def pwd_ls(dir="/tmp"):
    '''Run "pwd followed by "ls" on a given directory'''
    with safe_cd(dir):
        execute('pwd')
    execute("ls",dir)

__DEFAULT__ = pwd_ls

Using pynt contrib

Listing the tasks in build.py

$ pynt -l
Tasks in build file build.py:
  execute                Executes a command through the shell. Spaces should breakup the args. Usage: execute('grep', 'TODO', '*')
  pwd_ls      [Default]  Run "pwd followed by "ls" on a given directory

$ pynt "pwd_ls[/tmp/foo]"
[ build.pyc - Starting task "pwd_ls" ]
/tmp/foo
build.py	build.pyc
[ build.pyc - Completed task "pwd_ls" ]

Note that execute is included as a task in the build scripts as a task automatically when its imported from pynt-contrib. So you can use it as any other task

$ pynt "execute[ls,-la]"
[ build.pyc - Starting task "execute" ]
