Installation

Python version 2.7 is supported.

This library is can be built using the standard distutils mechanisms.

It is also registered with the Python Package Index (PyPI) as twextpy (the name twext is used by another module in PyPI) for use with pip and easy_install:

pip install twextpy

This will build and install the twext module along with its base dependencies. This library has a number of optional features which must be specified in order to download build and install their dependencies, for example:

pip install twextpy[DAL,Postgres]

These features are:

DAL

Enables use of the Database Abstraction Layer implemented in twext.enterprise.dal.

LDAP

Enables support for the Lightweight Directory Access Protocol in twext.who.ldap.

OpenDirectory

Enables support for the (Mac OS) OpenDirectory framework in twext.who.opendirectory.

Oracle

Enables support for Oracle database connectivity in twext.enterprise and Oracle syntax in twext.enterprise.dal.

Postgres

Enables support for Postgres database connectivity in twext.enterprise.

Development

If you are planning to work on this library, you can manage this with standard distutils mechanisms. There are, however, some tools in the bin directory which automate this management for you.

To use these tools, you must have pip on your system. If you do not have pip, instructions for installing it are at http://www.pip-installer.org/en/latest/installing.html. The script install_pip (requires sudo access) automates this for you.

The shell script develop downloads and builds any dependancies and sets up a development environment. develop handles non-Python as well as Python dependancies.

The tools python, pyflakes, trial, and twistd are wrappers around the cooresponding commands that use develop to ensure that dependancies are available, PYTHONPATH is set up correctly, etc.

test runs all of the unit tests and does linting. It should be run before checking in any code.
