Pysetup Tutorial
================
Getting started
---------------
Pysetup is a simple script that supports the following features:
- install, remove, list, and verify Python packages;
- search for available packages on PyPI or any *Simple Index*;
- verify installed packages (md5sum, installed files, version).
Finding out what's installed
----------------------------
Pysetup makes it easy to find out what Python packages are installed::
$ pysetup list virtualenv
'virtualenv' 1.6 at '/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info'
$ pysetup list
'pyverify' 0.8.1 at '/opt/python3.3/lib/python3.3/site-packages/pyverify-0.8.1.dist-info'
'virtualenv' 1.6 at '/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info'
...
Installing a distribution
-------------------------
Pysetup can install a Python project from the following sources:
- PyPI and Simple Indexes;
- source directories containing a valid :file:`setup.py` or :file:`setup.cfg`;
- distribution source archives (:file:`project-1.0.tar.gz`, :file:`project-1.0.zip`);
- HTTP (http://host/packages/project-1.0.tar.gz).
Installing from PyPI and Simple Indexes::
$ pysetup install project
$ pysetup install project==1.0
Installing from a distribution source archive::
$ pysetup install project-1.0.tar.gz
Installing from a source directory containing a valid :file:`setup.py` or
:file:`setup.cfg`::
$ cd path/to/source/directory
$ pysetup install
$ pysetup install path/to/source/directory
Installing from HTTP::
$ pysetup install http://host/packages/project-1.0.tar.gz
Retrieving metadata
-------------------
You can gather metadata from two sources, a project's source directory or an
installed distribution. The `pysetup metadata` command can retrieve one or
more metadata fields using the `-f` option and a metadata field as the
argument. ::
$ pysetup metadata virtualenv -f version -f name
Version:
1.6
Name:
virtualenv
$ pysetup metadata virtualenv
Metadata-Version:
1.0
Name:
virtualenv
Version:
1.6
Platform:
UNKNOWN
Summary:
Virtual Python Environment builder
...
.. seealso::
There are three metadata versions, 1.0, 1.1, and 1.2. The following PEPs
describe specifics of the field names, and their semantics and usage. 1.0
:PEP:`241`, 1.1 :PEP:`314`, and 1.2 :PEP:`345`
Removing a distribution
-----------------------
You can remove one or more installed distributions using the `pysetup remove`
command::
$ pysetup remove virtualenv
removing 'virtualenv':
/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/dependency_links.txt
/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/entry_points.txt
/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/not-zip-safe
/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/PKG-INFO
/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/SOURCES.txt
/opt/python3.3/lib/python3.3/site-packages/virtualenv-1.6-py3.3.egg-info/top_level.txt
Proceed (y/n)? y
success: removed 6 files and 1 dirs
The optional '-y' argument auto confirms, skipping the conformation prompt::
$ pysetup remove virtualenv -y
Getting help
------------
All pysetup actions take the `-h` and `--help` options which prints the commands
help string to stdout. ::
$ pysetup remove -h
Usage: pysetup remove dist [-y]
or: pysetup remove --help
Uninstall a Python package.
positional arguments:
dist installed distribution name
optional arguments:
-y auto confirm package removal
Getting a list of all pysetup actions and global options::
$ pysetup --help
Usage: pysetup [options] action [action_options]
Actions:
run: Run one or several commands
metadata: Display the metadata of a project
install: Install a project
remove: Remove a project
search: Search for a project in the indexes
list: List installed projects
graph: Display a graph
create: Create a project
generate-setup: Generate a backward-comptatible setup.py
To get more help on an action, use:
pysetup action --help
Global options:
--verbose (-v) run verbosely (default)
--quiet (-q) run quietly (turns verbosity off)
--dry-run (-n) don't actually do anything
--help (-h) show detailed help message
--no-user-cfg ignore pydistutils.cfg in your home directory
--version Display the version
