buildout-versions-checker 1.0

Usage

If you use the practical convention to pin the versions of all the eggs used in your buildout into a file, you will find this package useful for checking if any newest version of the eggs are available on Pypi.

Here an example of a version file:

$ cat versions.cfg
[versions]
Pillow                  = 2.0.0
pytz                    = 2012j
South                   = 0.8.1
django                  = 1.5
django-tagging          = 0.3.1

Now let’s execute the check-buildout-updates script:

$ ./check-buildout-updates
[versions]
Pillow                  = 2.1.0
pytz                    = 2013b
South                   = 0.8.2
django                  = 1.5.2

You can now update the versions.cfg file accordingly to your needs.

Options

usage: check-buildout-updates [-h] [-s SOURCE] [-i INCLUDES] [-e EXCLUDES]
                              [-w] [--indent INDENTATION]
                              [--service-url SERVICE_URL] [--timeout TIMEOUT]
                              [-t THREADS] [-v] [-q]

Check availables updates from a version section of a buildout script

optional arguments:
  -h, --help            show this help message and exit
  -s SOURCE, --source SOURCE
                        The file where versions are pinned (default:
                        versions.cfg)
  -i INCLUDES, --include INCLUDES
                        Include package when checking updates (can be used
                        multiple times)
  -e EXCLUDES, --exclude EXCLUDES
                        Exclude package when checking updates (can be used
                        multiple times)
  -w, --write           Write the updates in the source file
  --indent INDENTATION  Spaces used when indenting "key = value" (default: 24)
  --service-url SERVICE_URL
                        The service to use for checking the packages (default:
                        http://pypi.python.org/pypi)
  --timeout TIMEOUT     Timeout for each request (default: 10s)
  -t THREADS, --threads THREADS
                        Threads used for checking the versions in parallel
  -v                    Increase verbosity (specify multiple times for more)
  -q                    Decrease verbosity (specify multiple times for more)

Buildout integration

You can easily integrate this script into your buildout script to automaticly find and write the updates.

[buildout]
parts                   = evolution

[evolution]
recipe                  = zc.recipe.egg
eggs                    = buildout-versions-checker
scripts                 = check-buildout-updates=evolve
arguments               = '-s buildout.cfg -w'

With this part into your buildout script a new script named ./bin/evolve, will check available updates for the eggs listed in the versions section.

Python compatibility

Buildout-versions-checker has been originally developed for Python 2.7, but has been ported and tested for Python 3.2 and 3.3.
