Port of Doug Hellmann's virtualenvwrapper to Windows batch scripts
Project description
virtualenvwrapper-win
=====================
This is a port of Doug Hellmann's `virtualenvwrapper <http://www.doughellmann.com/projects/virtualenvwrapper/>`_
to Windows batch scripts. The idea behind virtualenvwrapper is to ease usage of
Ian Bicking's `virtualenv <http://pypi.python.org/pypi/virtualenv>`_, a tool
for creating isolated Python virtual environments, each with their own libraries
and site-packages.
These scripts are only tested on **Windows 7** in **regular command prompt**.
**They will not work in Powershell.** There are other virtualenvwrapper
projects out there for Powershell.
They should work on any version of Windows (Windows XP, Windows Vista, Windows 7).
**However**, they depend on an executable `where.exe` being in your path, which
is only provided in Vista and 7. If you are using XP, try [the answer to this post on superuser.com](http://superuser.com/questions/249725/where-to-download-where-exe-tool-for-windows-xp) to get a suitable where.exe (unsupported and untested).
Installation
------------
**For Windows only**
Installed scripts are placed in ``%PYTHONHOME%\Scripts``.
To install, run the following in an elevated command prompt::
pip install virtualenvwrapper-win
pyassoc
or download the source and run the following in an elevated command prompt::
python setup.py install
pyassoc
**Optional**: Add an environment variable WORKON_HOME to specify the path to store environments. By default, this is ``%USERPROFILE%\Envs``.
**Note**: ``pyassoc``
Note that the batch script ``pyassoc`` requires an elevated command prompt or that UAC is disabled. This script associates .py files with ``python.bat``, a simple batch file that calls the right ``python.exe`` based on whether you have an active virtualenv. This allows you to call python scripts from the command line and have the right python interpreter invoked. Take a look at the source -- it's incredibly simple but the best way I've found to handle conditional association of a file extension.
Main Commands
-------------
``mkvirtualenv <name>``
Create a new virtualenv environment named *<name>*. The environment will
be created in WORKON_HOME.
``lsvirtualenv``
List all of the enviornments stored in WORKON_HOME.
``rmvirtualenv <name>``
Remove the environment *<name>*. Uses ``folder_delete.bat``.
``workon [<name>]``
If *<name>* is specified, activate the environment named *<name>* (change
the working virtualenv to *<name>*). If a project directory has been defined,
we will change into it.
If no argument is specified, list the available environments.
``deactivate``
Deactivate the working virtualenv and switch back to the default system
Python.
``add2virtualenv <full_path>``
If a virtualenv environment is active, appends *<full_path>* to
``virtualenv_path_extensions.pth`` inside the environment's site-packages,
which effectively adds *<full_path>* to the environment's PYTHONPATH.
If a virtualenv environment is not active, appends *<full_path>* to
``virtualenv_path_extensions.pth`` inside the default Python's
site-packages.
Convenience Commands
--------------------
``cdproject``
If a virtualenv environment is active and a projectdir has been defined,
change the current working directory to active virtualenv's project directory.
``cd-`` will return you to the last directory you were in before calling
``cdproject``.
``cdsitepackages``
If a virtualenv environment is active, change the current working
directory to the active virtualenv's site-packages directory. If
a virtualenv environment is not active, change the current working
directory to the default Python's site-packages directory. ``cd-``
will return you to the last directory you were in before calling
``cdsitepackages``.
``cdvirtualenv``
If a virtualenv environment is active, change the current working
directory to the active virtualenv base directory. If a virtualenv
environment is not active, change the current working directory to
the base directory of the default Python. ``cd-`` will return you
to the last directory you were in before calling ``cdvirtualenv``.
``lssitepackages``
If a virtualenv environment is active, list that environment's
site-packages. If a virtualenv environment is not active, list the
default Python's site-packages. Output includes a basic listing of
the site-packages directory, the contents of easy-install.pth,
and the contents of virtualenv_path_extensions.pth (used by
``add2virtualenv``).
``setprojectdir <full_path>``
If a virtualenv environment is active, define *<full_path>* as project
directory containing the source code. This allows the use of ``cdproject``
to change the working directory. In addition, the directory will be
added to the environment using ``add2virtualenv``.
``toggleglobalsitepackages``
If a virtualenv environment is active, toggle between having the
global site-packages in the PYTHONPATH or just the virtualenv's
site-packages.
