multipip

pip utility refuses to handle multiple requirements for one package:

$ pip install 'nose>=1.2' 'nose>=2' 'nose<4'
Double requirement given: nose>=2 (already in nose>=1.2, name='nose')

Use multipip to join these requirements:

$ multipip 'nose>=1.2' 'nose>=2' 'nose<4'
nose>=2,<4

multipip can be used to run `pip`:

$ pip install $(multipip -r pip-requires)
...

Files of requirements can be used as well:

$ cat pip-requires
nose<4
$ multipip 'nose>=1.2' 'nose>=2' -r pip-requires
nose>=2,<4

multipip prints error messages for incompatible requirements to stderr and chooses the first one (note: command-line requirements take precedence over files):

$ cat pip-requires
pip==1.3
$ multipip 'pip==1.2' -r pip-requires
pip: incompatible requirements
Choosing:
    command line: pip==1.2
Conflicting:
    -r pip-requires (line 1): pip==1.3
pip==1.2

It is possible to filter some packages from printed output. This can be useful for a huge pip-requires file:

$ cat pip-requires
nose<4
pip==1.2
nose>=1.2
$ multipip -r pip-requires --ignore-packages nose
pip==1.2

Installed packages can be filtered, too (they are taken from pip freeze):

$ cat pip-requires
nose<4
pip==1.2
nose>=1.2
$ pip freeze | grep nose
nose==1.1.2
$ multipip -r pip-requires --ignore-installed
pip==1.2

py2rpm

Distutils provides an interface for building RPMs:

$ python ./setup.py bdist_rpm

This tool has several problems:

• Red Hat based distros use different package names, e.g., python-setuptools instead of distribute, python-nose instead of nose and so on...
• Requires and Conflicts sections for generated RPM are incorrect.
• Sometimes not all required files are packaged.
• Miscellaneous problems with man files;
• Package directory in /usr/lib*/python*/site-packages/<pkg> is not owned by any RPM;
• Some packages (like selenium) are architecture dependent but bdist_rpm generates BuildArch: noarch for them.

py2rpm is aimed to solve all these problems.

py2rpm accepts a list of archive names or package directories and builds RPMs (current directory is used by default):

$ py2rpm
...
Wrote: /home/guest/rpmbuild/SRPMS/python-multipip-0.1-1.src.rpm
Wrote: /home/guest/rpmbuild/RPMS/noarch/python-multipip-0.1-1.noarch.rpm
...

yyoom

yyoom uses the yum API to provide nice command-line interface to package management. It is able to install and remove packages in the same transaction (see yyoom transaction --help), list available or installed packages and a bit more. It writes results of its work to standard output in JSON (which is much easier to use from other programs).

explode_envra

specprint uses the rpm API to provide a interface to printing the details of an rpm filename in a easy to parse format (aka the envra format). It writes results of its work to standard output in JSON (which is much easier to use from other programs):

$ ./tools/explode_envra 'gtk3-3.10.9-1.fc20.x86_64.rpm' 'libxslt-1.1.28-5.fc20.x86_64.src.rpm'
{"release": "1.fc20", "epoch": "", "version": "3.10.9", "arch": "x86_64", "name": "gtk3"}
{"release": "5.fc20.x86_64", "epoch": "", "version": "1.1.28", "arch": "src", "name": "libxslt"}

specprint

specprint uses the rpm API to provide a interface to printing the details of an rpm spec file in a easy to parse format. It writes results of its work to standard output in JSON (which is much easier to use from other programs):
