.. highlightlang:: cfg ******************************************* Specification of the :file:`setup.cfg` file ******************************************* .. :version: 1.0 This document describes the :file:`setup.cfg`, an ini-style configuration file (compatible with :class:`configparser.RawConfigParser`) configuration file used by Packaging to replace the :file:`setup.py` file. Each section contains a description of its options. - Options that are marked *multi* can have multiple values, one value per line. - Options that are marked *optional* can be omitted. - Options that are marked *environ* can use environment markers, as described in :PEP:`345`. The sections are: global Global options not related to one command. metadata Name, version and other information defined by :PEP:`345`. files Modules, scripts, data, documentation and other files to include in the distribution. command sections Options given for specific commands, identical to those that can be given on the command line. Global options ============== Contains global options for Packaging. This section is shared with Distutils. commands Defined Packaging command. A command is defined by its fully qualified name. *optional*, *multi* Examples:: [global] commands = package.setup.CustomSdistCommand package.setup.BdistDeb compilers Defined Packaging compiler. A compiler is defined by its fully qualified name. *optional*, *multi* Example:: [global] compilers = hotcompiler.SmartCCompiler setup_hook defines a callable that will be called right after the :file:`setup.cfg` file is read. The callable receives the configuration in form of a mapping and can make some changes to it. *optional* Example:: [global] setup_hook = package.setup.customize_dist Metadata ======== The metadata section contains the metadata for the project as described in :PEP:`345`. Field names are case-insensitive. Fields: name Name of the project. version Version of the project. Must comply with :PEP:`386`. platform Platform specification describing an operating system supported by the distribution which is not listed in the "Operating System" Trove classifiers (:PEP:`301`). *optional*, *multi* supported-platform Binary distributions containing a PKG-INFO file will use the Supported-Platform field in their metadata to specify the OS and CPU for which the binary distribution was compiled. The semantics of the Supported-Platform field are free form. *optional*, *multi* summary A one-line summary of what the distribution does. (Used to be called *description* in Distutils1.) description A longer description. (Used to be called *long_description* in Distutils1.) A file can be provided in the *description-file* field. *optional* description-file path to a text file that will be used for the **description** field. *optional* keywords A list of additional keywords to be used to assist searching for the distribution in a larger catalog. Comma or space-separated. *optional* home-page The URL for the distribution's home page. download-url The URL from which this version of the distribution can be downloaded. *optional* author Author's name. *optional* author-email Author's e-mail. *optional* maintainer Maintainer's name. *optional* maintainer-email Maintainer's e-mail. *optional* license A text indicating the term of uses, when a trove classifier does not match. *optional*. classifiers Classification for the distribution, as described in PEP 301. *optional*, *multi*, *environ* requires-dist name of another packaging project required as a dependency. The format is *name (version)* where version is an optional version declaration, as described in PEP 345. *optional*, *multi*, *environ* provides-dist name of another packaging project contained within this distribution. Same format than *requires-dist*. *optional*, *multi*, *environ* obsoletes-dist name of another packaging project this version obsoletes. Same format than *requires-dist*. *optional*, *multi*, *environ* requires-python Specifies the Python version the distribution requires. The value is a version number, as described in PEP 345. *optional*, *multi*, *environ* requires-externals a dependency in the system. This field is free-form, and just a hint for downstream maintainers. *optional*, *multi*, *environ* project-url A label, followed by a browsable URL for the project. "label, url". The label is limited to 32 signs. *optional*, *multi* Example:: [metadata] name = pypi2rpm version = 0.1 author = Tarek Ziadé author-email = tarek@ziade.org summary = Script that transforms an sdist archive into a RPM package description-file = README home-page = http://bitbucket.org/tarek/pypi2rpm/wiki/Home project-url: Repository, http://bitbucket.org/tarek/pypi2rpm/ RSS feed, https://bitbucket.org/tarek/pypi2rpm/rss classifier = Development Status :: 3 - Alpha License :: OSI Approved :: Mozilla Public License 1.1 (MPL 1.1) You should not give any explicit value for metadata-version: it will be guessed from the fields present in the file.

Note:: The :file:`setup.cfg` configuration file is included by default. Contrary to Distutils, :file:`README` (or :file:`README.txt`) and :file:`setup.py` are not included by default. Resources --------- This section describes the files used by the project which must not be installed in the same place that python modules or libraries, they are called **resources**. They are for example documentation files, script files, databases, etc... For declaring resources, you must use this notation:: source = destination Data-files are declared in the **resources** field in the **file** section, for example:: [files] resources = source1 = destination1 source2 = destination2 The **source** part of the declaration are relative paths of resources files (using unix path separator **/**). For example, if you've this source tree:: foo/ doc/ doc.man scripts/ foo.sh Your setup.cfg will look like:: [files] resources = doc/doc.man = destination_doc scripts/foo.sh = destination_scripts The final paths where files will be placed are composed by : **source** + **destination**. In the previous example, **doc/doc.man** will be placed in **destination_doc/doc/doc.man** and **scripts/foo.sh** will be placed in **destination_scripts/scripts/foo.sh**. (If you want more control on the final path, take a look at base_prefix_). The **destination** part of resources declaration are paths with categories. Indeed, it's generally a bad idea to give absolute path as it will be cross incompatible. So, you must use resources categories in your **destination** declaration. Categories will be replaced by their real path at the installation time. Using categories is all benefit, your declaration will be simpler, cross platform and it will allow packager to place resources files where they want without breaking your code. Categories can be specified by using this syntax:: {category} Default categories are: * config * appdata * appdata.arch * appdata.persistent * appdata.disposable * help * icon * scripts * doc * info * man A special category also exists **{distribution.name}** that will be replaced by the name of the distribution, but as most of the defaults categories use them, so it's not necessary to add **{distribution.name}** into your destination. If you use categories in your declarations, and you are encouraged to do, final path will be:: source + destination_expanded .. _example_final_path: For example, if you have this setup.cfg:: [metadata] name = foo [files] resources = doc/doc.man = {doc} And if **{doc}** is replaced by **{datadir}/doc/{distribution.name}**, final path will be:: {datadir}/doc/foo/doc/doc.man Where {datafir} category will be platform-dependent. More control on source part ^^^^^^^^^^^^^^^^^^^^^^^^^^^ Glob syntax """"""""""" When you declare source file, you can use a glob-like syntax to match multiples file, for example:: scripts/* = {script} Will match all the files in the scripts directory and placed them in the script category. Glob tokens are: * ``*``: match all files. * ``?``: match any character. * ``**``: match any level of tree recursion (even 0). * ``{}``: will match any part separated by comma (example: ``{sh,bat}``). .. TODO Add examples Order of declaration """""""""""""""""""" The order of declaration is important if one file match multiple rules. The last rules matched by file is used, this is useful if you have this source tree:: foo/ doc/ index.rst setup.rst documentation.txt doc.tex README And you want all the files in the doc directory to be placed in {doc} category, but README must be placed in {help} category, instead of listing all the files one by one, you can declare them in this way:: [files] resources = doc/* = {doc} doc/README = {help} Exclude """"""" You can exclude some files of resources declaration by giving no destination, it can be useful if you have a non-resources file in the same directory of resources files:: foo/ doc/ RELEASES doc.tex documentation.txt docu.rst Your **files** section will be:: [files] resources = doc/* = {doc} doc/RELEASES = More control on destination part ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. _base_prefix: Defining a base prefix """""""""""""""""""""" When you define your resources, you can have more control of how the final path is compute. By default, the final path is:: destination + source This can generate long paths, for example (example_final_path_):: {datadir}/doc/foo/doc/doc.man When you declare your source, you can use whitespace to split the source in **prefix** **suffix**. So, for example, if you have this source:: docs/ doc.man The **prefix** is "docs/" and the **suffix** is "doc.html". .. note:: Separator can be placed after a path separator or replace it. So these two sources are equivalent:: docs/ doc.man docs doc.man .. note:: Glob syntax is working the same way with standard source and splitted source. So these rules:: docs/* docs/ * docs * Will match all the files in the docs directory. When you use splitted source, the final path is compute in this way:: destination + prefix So for example, if you have this setup.cfg:: [metadata] name = foo [files] resources = doc/ doc.man = {doc} And if **{doc}** is replaced by **{datadir}/doc/{distribution.name}**, final path will be:: {datadir}/doc/foo/doc.man Overwriting paths for categories ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This part is intended for system administrators or downstream OS packagers. The real paths of categories are registered in the *sysconfig.cfg* file installed in your python installation. This file uses an ini format too. The content of the file is organized into several sections: * globals: Standard categories's paths. * posix_prefix: Standard paths for categories and installation paths for posix system. * other ones XXX Standard categories paths are platform independent, they generally refers to other categories, which are platform dependent. :mod:`sysconfig` will choose these category from sections matching os.name. For example:: doc = {datadir}/doc/{distribution.name} It refers to datadir category, which can be different between platforms. In posix system, it may be:: datadir = /usr/share So the final path will be:: doc = /usr/share/doc/{distribution.name} The platform-dependent categories are: * confdir * datadir * libdir * base Defining extra categories ^^^^^^^^^^^^^^^^^^^^^^^^^ .. TODO Examples ^^^^^^^^ These examples are incremental but work unitarily. Resources in root dir """"""""""""""""""""" Source tree:: babar-1.0/ README babar.sh launch.sh babar.py :file:`setup.cfg`:: [files] resources = README = {doc} *.sh = {scripts} So babar.sh and launch.sh will be placed in {scripts} directory. Now let's move all the scripts into a scripts directory. Resources in sub-directory """""""""""""""""""""""""" Source tree:: babar-1.1/ README scripts/ babar.sh launch.sh LAUNCH babar.py :file:`setup.cfg`:: [files] resources = README = {doc} scripts/ LAUNCH = {doc} scripts/ *.sh = {scripts} It's important to use the separator after scripts/ to install all the shell scripts into {scripts} instead of {scripts}/scripts. Now let's add some docs. Resources in multiple sub-directories """"""""""""""""""""""""""""""""""""" Source tree:: babar-1.2/ README scripts/ babar.sh launch.sh LAUNCH docs/ api man babar.py :file:`setup.cfg`:: [files] resources = README = {doc} scripts/ LAUNCH = {doc} scripts/ *.sh = {scripts} doc/ * = {doc} doc/ man = {man} You want to place all the file in the docs script into {doc} category, instead of man, which must be placed into {man} category, we will use the order of declaration of globs to choose the destination, the last glob that match the file is used. Now let's add some scripts for windows users. Complete example """""""""""""""" Source tree:: babar-1.3/ README doc/ api man scripts/ babar.sh launch.sh babar.bat launch.bat LAUNCH :file:`setup.cfg`:: [files] resources = README = {doc} scripts/ LAUNCH = {doc} scripts/ *.{sh,bat} = {scripts} doc/ * = {doc} doc/ man = {man} We use brace expansion syntax to place all the shell and batch scripts into {scripts} category. Command sections ================ To pass options to commands without having to type them on the command line for each invocation, you can write them in the :file:`setup.cfg` file, in a section named after the command. Example:: [sdist] # special function to add custom files manifest-builders = package.setup.list_extra_files [build] use-2to3 = True [build_ext] inplace = on [check] strict = on all = on Option values given in the configuration file can be overriden on the command line. See :ref:`packaging-setup-config` for more information.
