zc.buildout recipes to perform a variety of tasks required by Bob satellite packages
Project description
This package contains a number of recipes to be used to build Satellite Packages for Bob, a signal-processing and machine learning toolbox originally developed by the Biometrics Group at Idiap, in Switzerland.
C++/Python Package Builder
This recipe can build C++/Python extensions that link against Bob using pkg-config. This recipe will look at the buildout section entry called prefixes, that potentially lists prefixes that should be prepended to the default pkg-config environment:
[mycxx] recipe = xbob.buildout:develop
This recipe also, indirectly, generates a python interpreter named (by default) xpython.builder. This program allows you to build the package using installed or development eggs. Our build therefore by-passes the normal package building via setuptools/distribute and use buildout for finding the eggs which are required for the build. Note this has nothing to do with package use, for which you can use the recipes below.
Supported Options
- debug
If set, the module will be compiled with debugging symbols and with optimization turned off.
- verbose
If set, it will output the compilation commands while compiling the module.
- eggs
The eggs option specifies a list of eggs to use for building this package. Each string must be given on a separate line. If you don’t specify anything, at least xbob.extension is included. Otherwise, we will add that one to your list, if not yet available.
- interpreter
The name of the interpreter that is generated for building this package. If you don’t set it, it is by default called xpython.builder.
- buildout.prefixes
A list of directories where this recipe will look for subdirectories with the stem lib/pkgconfig. All directories matching this condition are appended to the pkg-config environment using the environment variable PKG_CONFIG_PATH.
Multi-Script Installer
This recipe installs all most used scripts and interpreter proxies for your package. It will look at the buildout section entry called prefixes, that potentially lists prefixes that should be prepended to the default python environment. In these prefixes, it will look for standard python directories. If one or more are found, these paths are prepended into the resulting scripts generated by this recipe and eggs will be searched on those locations prioritarily.
By default, this recipe will use the eggs defined at the buildout section called eggs, but that can be overriden locally. It generates these scripts:
- python
A pre-configured python interpreter
- ipython
If the package ipython is installed, a pre-configured ipython interpreter will also be created
- nosetests
If the package nose is installed, a test runner called nosetests will be created on the bin directory of buildout.
- sphinx- utils
If the package sphinx is installed, several sphinx utilities will be created on the bin directory of buildout.
- package scripts
Package scripts will be created taking into account the prefixes established for this section or globally (as a second priority).
To use this recipe, you just have to simply do:
[scripts] recipe = xbob.buildout:scripts
Supported Options
The recipe supports the following options:
- prefixes
A list of directories where this recipe will look for subdirectories with the stem lib/python*/site-packages. All directories matching this condition are appended to the search paths. If not given, the value of this property defaults to buildout.prefixes. Both can be empty, which makes this recipe default to using standard available paths.
- eggs
The eggs option specifies a list of eggs to use for building this package. Each string must be given on a separate line. If not given, the value of this property defaults to buildout.eggs.
- dependent-scripts
If set to the string true, scripts will be generated for all required eggs in addition to the eggs specifically named.
- interpreter
The name of a script to generate that allows access to a Python interpreter that has the path set based on the eggs installed. If you don’t specify anything, the default value python will be used.
- extra-paths
Extra paths to be appended in a generated script. To prepend, using the prefixes entry.
- nose-flags
These are extra flags that are appended to the given nosetests command line, automatically. Use this to preset arguments you like running all the time like -v, for example.
Other Recipes
This package also provides recipes that allow for the discrete installation of interpreters and support programs, lumped together with the scripts recipe described above. You can use some of the options described above with these recipes. For example, the prefixes, eggs and extra-paths are considered by all these recipes.
- python
This recipe generates just a python interpreter on the binary directory. Extra options considered: interpreter.
- ipython
This recipe generates an IPython interpreter on the binary directory. Extra options considered: interpreter.
- egg.scripts
This recipe generates only the scripts (and dependent scripts) for the package. Extra options considered: dependent-scripts.
- nose
This recipe generates only the nosetests program. Extra options considered are:nose-flags.
- sphinx
This recipe generates only the Sphinx documentation generator applications. Extra options considered: none.
- gdb-python
This recipe generates a gdb launcher using the python interpreter so you can start your scripts directly typing gdb-python myscript.py.
