Bento is an alternative to distutils-based packaging tools such as distutils, setuptools or distribute. Bento focus on reproducibility, extensibility and simplicity (in that order).
Packaging is as simple as writing a bento.info file with a file which looks as follows:
Name: Foo Author: John Doe Library: Packages: foo
The package is then installed with bentomaker, the command line interface to bento:
To install bento, you can either:
install bento from itself (recommended):python bootstrap.py ./bentomaker install
install bento using setuptools (not recommended):python setup.py install
Bento supports python 3 as is, so there is no need to run 2to3 on it (doing so will probably break it).
Bento discussions happen on the bento Mailing list (email@example.com, archive on bento-ml). To subscribe, you simply need to send an email to the list. Development is on github. Bugs should be reported on bento issue-tracker. Online documentation is available on github as well.
Why you should use bento ?
- Straightfoward package description, in an indentation-based syntax similar to python
- Simple packages can have their setup.py automatically converted through the 'convert' command
- Distutils compatibility mode so that a bento package can be installed through pip
- Adding new commands is simple
- Pluggable build-backend: you can build your C extensions with a real build system such as waf or scons.
- Easy to customize install paths from the command line, with sensible defaults on every platform
- Installing data files such as manpages, configuration, etc... is straightforward and customizable through the command line
- Supports all python versions >= 2.4 (including 3.x)
- Designed with reproducibility in mind: re-running the same command twice should produce the same result (idempotency)
- Preliminary support for windows installers (.exe), eggs and mpkg.
But bento does more:
Designed as a library from the ground up, with a focus on robustness and extensibility:
- new commands can be inserted before/after an existing one without modifying the latter (no monkey-patching needed)
- easy to add command line options to existing commands
- each command has a pre/post hook
- API designed such as commands need to know very little from each other.
- Moving toward a node-based architecture for robust file location (waf-based design)
- No global variable/singleton in bento itself
Easily bundable, one-file distribution to avoid extra-dependencies when using bento. You only need to add one file to your sources, no need for your users to install anything.
Basic support for console scripts ala setuptools
Dependency-based extension builders (source content change is automatically rebuilt)
Parallel build support for C extensions
Low-level interface to the included build tool to override/change any compilation parameter (compilation flag, compiler, etc...)
- Reliable and fast (parallel) 2->3 convertion.
- Support for msi packages
- Reliable conversion between packaging formats on the platforms where it makes sense (egg <-> wininst, mpkg <-> egg, etc...)
- Provide API to enable Linux distributors to write simple extensions for packaging bento-packages as they see fit
- Infrastructure for a correctly designed package index, using well-known packaging practices instead of the broken easy_install + pypi model (easy mirroring, enforced metadata, indexing to enable querying-before-installing, reliable install, etc...).
WHILE BENTO IS ALREADY USABLE, IT MAY STILL SIGNIFICANTLY CHANGE IN BACKWARD INCOMPATIBLE WAYS UNTIL THE FIRST ALPHA.
