pybuild - Online in the Cloud

PROGRAM:

NAME

pybuild - invokes various build systems for requested Python versions in order to build
modules and extensions

SYNOPSIS

pybuild [ACTION] [BUILD SYSTEM ARGUMENTS] [DIRECTORIES] [OPTIONS]

DEBHELPER COMMAND SEQUENCER INTEGRATION

· build depend on dh-python,

· build depend on python3-all, python-all-dbg, pypy, etc. (for all supported Python
interpreters, pybuild will use it to create a list of interpreters to build for),

· add --buildsystem=pybuild to dh's arguments in debian/rules,

· if more than one binary package is build: add debian/python-foo.install files, or export
PYBUILD_NAME=modulename (modulename will be used to guess binary package prefixes), or
export PYBUILD_DESTDIR env. variables in debian/rules

debian/rules file example:

#! /usr/bin/make -f
export PYBUILD_NAME=foo
%:
dh $@ --with python2,python3 --buildsystem=pybuild

OPTIONS

Most options can be set (in addition to command line) via environment variables.
PyBuild will check:

· PYBUILD_OPTION_VERSIONED_INTERPRETER (f.e. PYBUILD_CLEAN_ARGS_python3.2)

· PYBUILD_OPTION_INTERPRETER (f.e. PYBUILD_CONFIGURE_ARGS_python3-dbg)

· PYBUILD_OPTION (f.e. PYBUILD_INSTALL_ARGS)

optional arguments
-h, --help
show this help message and exit

-v, --verbose
turn verbose mode on

-q, --quiet
doesn't show external command's output

-qq, --really-quiet
be quiet

--version
show program's version number and exit

ACTION
The default is to build, install and test the library using detected build system
version by version. Selecting one of following actions, will invoke given action for
all versions - one by one - which (contrary to the default action) in some build
systems can overwrite previous results.

--detect
return the name of detected build system

--clean
clean files using auto-detected build system specific methods

--configure
invoke configure step for all requested Python versions

--build
invoke build step for all requested Python versions

--install
invoke install step for all requested Python versions

--test invoke tests for auto-detected build system

--list-systems
list available build systems and exit

TESTS
unittest's discover from standard library (available in Python 2.7 and >= 3.2) is used
in test step by default.

--test-nose
use nose module in test step, remember to add python-nose and/or python3-nose to
Build-Depends

--test-pytest
use pytest module in test step, remember to add python-pytest and/or
python3-pytest to Build-Depends

--test-tox
use tox command in test step, remember to add python-tox to Build-Depends.
Requires tox.ini file

BUILD SYSTEM ARGUMENTS
Additional arguments passed to the build system. --system=custom requires complete
command in --foo-args parameters.

--before-clean COMMAND
invoked before the clean command

--clean-args ARGUMENTS
arguments added to clean command generated by build system plugin

--after-clean COMMAND
invoked after the clean command

--before-configure COMMAND
invoked before the configure command

--configure-args ARGUMENTS
arguments added to configure command generated by build system plugin

--after-configure COMMAND
invoked after the configure command

--before-build COMMAND
invoked before the build command

--build-args ARGUMENTS
arguments added to build command generated by build system plugin

--after-build COMMAND
invoked after the build command

--before-install COMMAND
invoked before the install command

--install-args ARGUMENTS
arguments added to install command generated by build system plugin

--after-install COMMAND
invoked after the install command

--before-test COMMAND
invoked before the test command

--test-args ARGUMENTS
arguments added to test command generated by build system plugin

--after-test COMMAND
invoked after the test command

variables that can be used in ARGUMENTS and COMMAND
· {version} will be replaced with current Python version, you can also use
{version.major}, {version.minor}, etc.

· {interpreter} will be replaced with current interpreter, you can also use
{interpreter.include_dir}

· {dir} will be replaced with sources directory,

· {destdir} will be replaced with destination directory,

· {home_dir} will be replaced with temporary HOME directory, where plugins can keep their
data (.pybuild/interpreter_version/ by default),

· {build_dir} will be replaced with build directory

· {install_dir} will be replaced with install directory.

· {package} will be replaced with suggested package name, if --name (or PYBUILD_NAME) is
set to foo, this variable will be replaced to python-foo, python3-foo or pypy-foo
depending on interpreter which is used in given iteration.

DIRECTORIES
-d DIR, --dir DIR
set source files directory - base for other relative dirs [by default: current
working directory]

--dest-dir DIR
set destination directory [default: debian/tmp]

--ext-dest-dir DIR
set destination directory for .so files

--ext-pattern PATTERN
regular expression for files that should be moved if --ext-dest-dir is set
[default: .so(.[^/]*)?$]

--install-dir DIR
set installation directory [default: .../dist-packages]

--name NAME
use this name to guess destination directories (depending on interpreter, "foo"
sets debian/python-foo, debian/python3-foo, debian/python3-foo-dbg, etc.)

variables that can be used in DIR
· {version} will be replaced with current Python version,

· {interpreter} will be replaced with selected interpreter.

LIMITATIONS
-s SYSTEM, --system SYSTEM
select a build system [default: auto-detection]

-p VERSIONS, --pyver VERSIONS
build for Python VERSIONS. This option can be used multiple times. Versions can
be separated by space character. The default is all Python 3.X supported
versions.

-i INTERPRETER, --interpreter INTERPRETER
change interpreter [default: python{version}]

--disable ITEMS
disable action, interpreter, version or any mix of them. Note that f.e. python3
and python3-dbg are two different interpreters, --disable test/python3 doesn't
disable python3-dbg's tests.

disable examples
· --disable test/python2.5-dbg - disables tests for python2.5-dbg

· --disable '2.4 2.7' - disables all actions for version 2.4 and 2.7

· PYBUILD_DISABLE_python2=1 - disables all actions for Python 2.X

· PYBUILD_DISABLE_python3.3=test - disables tests for Python 3.3

· PYBUILD_DISABLE=test/python3.3 - same as above

· PYBUILD_DISABLE=configure/python3 2.4 pypy - disables configure action for all python3
interpreters, all actions for version 2.4, and all actions for pypy
