Python
|
|
======
|
|
|
|
Enables local Python and local Python package installation.
|
|
|
|
Local Python Installation
|
|
-------------------------
|
|
|
|
[pyenv][4] builds and installs multiple Python versions locally in the home
|
|
directory.
|
|
|
|
This module prepends the pyenv directory to the path variable to enable the
|
|
execution of `pyenv`.
|
|
|
|
### Usage
|
|
|
|
Install Python versions with `pyenv install` into *~/.pyenv/versions*.
|
|
|
|
Local Package Installation
|
|
--------------------------
|
|
|
|
Since version 2.6, Python supports per user package installation, as defined in
|
|
[PEP 370][1].
|
|
|
|
This module prepends per user site directories to the relevant path variables
|
|
to enable the execution of user installed scripts and the reading of
|
|
documentation.
|
|
|
|
### Usage
|
|
|
|
Install packages into the per user site directory with `easy_install --user` or
|
|
`pip install --user`.
|
|
|
|
virtualenvwrapper
|
|
-----------------
|
|
|
|
[virtualenvwrapper][2] is a frontend to the popular [virtualenv][3] utility.
|
|
|
|
virtualenv creates isolated Python environments and virtualenvwrapper provides
|
|
convenient shell functions to create, switch, and manage them.
|
|
|
|
### Usage
|
|
|
|
Install virtualenvwrapper.
|
|
|
|
Virtual environments are stored in *~/.virtualenvs*.
|
|
|
|
There are configuration variables that have to be set to enable certain features.
|
|
If you wish to use these features, export the variables in *~/.zshenv*
|
|
|
|
The variable `$PROJECT_HOME` tells virtualenvwrapper where to place project
|
|
working directories. It must be set and the directory created before `mkproject`
|
|
is used. Replace *Developer* with your projects directory.
|
|
|
|
export PROJECT_HOME="$HOME/Developer"
|
|
|
|
The variable `$VIRTUALENVWRAPPER_VIRTUALENV_ARGS` tells virtualenvwrapper what
|
|
arguments to pass to `virtualenv`. For example, set the value to
|
|
*--no-site-packages* to ensure that all new environments are isolated from the
|
|
system site-packages directory.
|
|
|
|
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages'
|
|
|
|
Aliases
|
|
-------
|
|
|
|
- `py` is short for `python`.
|
|
|
|
Functions
|
|
---------
|
|
|
|
- `python-info` exposes information about the Python environment via the
|
|
`$python_info` associative array.
|
|
|
|
Theming
|
|
-------
|
|
|
|
To display the name of the current virtual enviroment in a prompt, define the
|
|
following style in the `prompt_name_setup` function.
|
|
|
|
# %v - virtualenv name.
|
|
zstyle ':prezto:module:python:info:virtualenv' format 'virtualenv:%v'
|
|
|
|
Then add `$python_info[virtualenv]` to `$PROMPT` or `$RPROMPT` and call
|
|
`python-info` in the `prompt_name_preexec` hook function.
