Find newer package versions on PyPI

Project description


Find newer versions of your installed Python packages, or newer versions of packages in a buildout file.

This package provides a console script named checkversions.


you can install this package either in a virtualenv:

$ virtualenv sandbox
$ sandbox/bin/pip install z3c.checkversions
$ sandbox/bin/checkversions --help

or in your system:

$ sudo pip install z3c.checkversions
$ checkversions --help

or in a buildout:

parts = checkversions

eggs=z3c.checkversions [buildout]

Note that buildout support is optional and must be enabled with [buildout] so that zc.buildout is installed as well.

If you need buildout support while installing this package via pip you have to install it like this:

pip install z3c.checkversions[buildout]


$ checkversions -h
Usage: checkversions [-v] [-1] [-l LEVEL] [-i INDEX] [-b BLACKLIST] [buildout_file]

This script will check new package versions of either your current installed
distributions or a buildout file if provided. It can detect major or minor
versions availability: level 0 gets the highest version (X.y.z), level 1 gets
the highest intermediate version (x.Y.z), level 2 gets the highest minor
version (x.y.Z).  Using level 2, you can automatically retrieve all bugfix
versions of a buildout.  If you provide a blacklist file with bad versions,
these versions won't be suggested.

  -h, --help            show this help message and exit
  -l LEVEL, --level=LEVEL
                        Version level to check
  -i INDEX, --index=INDEX
                        Provide and alternative package index URL
  -b BLACKLIST, --blacklist=BLACKLIST
                        Provide a blacklist file with bad versions
  -1, --incremental     Suggest only one upgrade. Skip others.
  -v, --verbose         Verbose mode (prints old versions too)


For installed packages

Example with a virtualenv:

$ virtualenv --no-site-packages sandbox
$ sandbox/bin/pip install z3c.checkversions
$ sandbox/bin/checkversions -v -l 1
# Checking your installed distributions
pip=0.7.1 # was: 0.6.3

For a buildout

It can work either with a full buildout.cfg or with a simple versions.cfg file.

Here is a sample versions.cfg file:


You can generate a new versions.cfg

$ checkversions -v -l 1 versions.cfg
# Checking buildout file versions.cfg
somepackage=0.6.2 # was: 0.5.0
otherpackage=0.1.2 # was: 0.1.1

If you provide a blacklist file, such as blacklist.cfg containing bad versions, such as:


Then these versions won’t be suggested:

$ checkversions -v -l 1 versions.cfg -b blacklist.cfg
# Checking buildout file versions.cfg
somepackage=0.6.0 # was: 0.5.0
otherpackage=0.1.2 # was: 0.1.1

If you enable the –incremental option, only one upgrade will be suggested:

$ checkversions --incremental -v -l 1 versions.cfg
# Checking buildout file versions.cfg
somepackage=0.6.0 # was: 0.5.0

Run tests

Uncompress the archive, then run:

$ virtualenv .
$ bin/pip install tox
$ tox
