Thomas Nagy, 2006-2018 (ita) + +""" +This tool helps with finding Qt5 tools and libraries, +and also provides syntactic sugar for using Qt5 tools. + +The following snippet illustrates the tool usage::

+Load the "qt5" tool. + +You also need to edit your sources accordingly: + +- the normal way of doing things is to have your C++ files + include the .moc file. + This is regarded as the best practice (and provides much faster + compilations). + It also implies that the include paths have beenset properly. + +- to have the include paths added automatically, use the following:: + + from waflib.TaskGen import feature, before_method, after_method + @feature('cxx') + @after_method('process_source') + @before_method('apply_incpaths') + def add_includes_paths(self): + incs =

processing that does not require +.moc includes, see 'playground/slow_qt/'. + +A few options (--qt{dir,bin,...}) and environment variables +(QT5_{ROOT,DIR,MOC,UIC,XCOMPILE}) allow finer tuning of the tool, +tool path selection, etc; please read the source for more info. + +The detection uses pkg-config on Linux by default. The list of +libraries to be requested to pkg-config is formulated by scanning +in the QTLIBS directory (that can be passed via --qtlibs or by +setting the environment variable QT5_LIBDIR otherwise is derived +by querying qmake for QT_INSTALL_LIBS directory) for shared/static +libraries present. +Alternatively the list of libraries to be requested via pkg-config +can be set using the qt5_vars attribute, ie: + + conf.qt5_vars = ['Qt5Core', 'Qt5Gui', 'Qt5Widgets', 'Qt5Test']; + +This can speed up configuration phase if needed libraries are +known beforehand, can improve detection on systems with a +sparse QT5 libraries installation (ie.

+================ +This module provides a waf wrapper (i.e. waftool) around the C/C++ source code +checking tool 'cppcheck'. + +See http://cppcheck.sourceforge.net/ for more information on the cppcheck tool +itself. +Note that many linux distributions already provide a ready to install version +of cppcheck. On fedora, for instance, it can be installed using yum: + + 'sudo yum install cppcheck' + + +Usage +===== +In order to use this waftool simply add it to the 'options' and 'configure' +functions of your main waf script as shown in the example below: + + def options(opt): + opt.load('cppcheck', tooldir='./waftools') + + def configure(conf): + conf.load('cppcheck') + +Note that example shown above assumes that the cppcheck waftool is located in +the sub directory named 'waftools'. + +When configured as shown in the example above, cppcheck will automatically +perform a source code analysis on all C/C++ build tasks that have been +defined in your waf build system. + +The example shown below for a C program will be used as input for cppcheck when +building the task. + + def build(bld): + bld.program(name='foo', src='foobar.c') + +The result of the source code analysis will be stored both as xml and html +files in the build location for the task. Should any error be detected by +cppcheck the build will be aborted and a link to the html report will be shown. +By default, one index.html file is created for each task generator. A global +index.html file can be obtained by setting the following variable +in the configuration section: + + conf.env.CPPCHECK_SINGLE_HTML = False + +When needed source code checking by cppcheck can be disabled per task, per +detected error or warning for a particular task. It can be also be disabled for +all tasks. + +In order to exclude a task from source code checking add the skip option to the +task as shown below: + + def build(bld): + bld.program( + name='foo', + src='foobar.c' + cppcheck_skip=True + ) + +When needed problems detected by cppcheck may be suppressed using a file +containing a list of suppression rules. The relative or absolute path to this +file can be added to the build task as shown in the example below: + + bld.program( + name='bar', + src='foobar.c', + cppcheck_suppress='bar.suppress' + ) + +A cppcheck suppress file should contain one suppress rule per line. Each of +these rules will be passed as an '--suppress=' argument to cppcheck. + +Dependencies +================ +This waftool depends on the python pygments module, it is used for source code +syntax highlighting when creating the html reports. see http://pygments.org/ for +more information on this package. + +Remarks +================ +The generation of the html report is originally based on the cppcheck-htmlreport.py +script that comes shipped with the cppcheck tool. +""" + +import sys +import xml.etree.ElementTree as ElementTree +from waflib import Task, TaskGen, Logs, Context, Options + +PYGMENTS_EXC_MSG= ''' +The required module 'pygments' could not be found.

+Provides Python unit test support using :py:class:`waflib.Tools.waf_unit_test.utest` +task via the **pytest** feature. + +To use pytest the following is needed: + +1. Load `pytest` and the dependency `waf_unit_test` tools. +2. Create a task generator with feature `pytest` (not `test`) and customize behaviour with + the following attributes: + + - `pytest_source`: Test input files. + - `ut_str`: Test runner command, e.g. ``${PYTHON} -B -m unittest discover`` or + if nose is used: ``${NOSETESTS} --no-byte-compile ${SRC}``. + - `ut_shell`: Determines if ``ut_str`` is executed in a shell. Default: False. + - `ut_cwd`: Working directory for test runner. Defaults to directory of + first ``pytest_source`` file. + + Additionally the following `pytest` specific attributes are used in dependent taskgens: + + - `pytest_path`: Node or string list of additional Python paths. + - `pytest_libpath`: Node or string list of additional library paths. + +The `use` dependencies are used for both update calculation and to populate +the following environment variables for the `pytest` test runner: + +1. `PYTHONPATH` (`sys.path`) of any dependent taskgen that has the feature `py`: + + - `install_from` attribute is used to determine where the root of the Python sources + are located. If `install_from` is not specified the default is to use the taskgen path + as the root. + + - `pytest_path` attribute is used to manually specify additional Python paths. + +2. Dynamic linker search path variable (e.g. `LD_LIBRARY_PATH`) of any dependent taskgen with + non-static link_task. + + - `pytest_libpath` attribute is used to manually specify additional linker paths. + +3. Java class search path (CLASSPATH) of any Java/Javalike dependency + +Note: `pytest` cannot automatically determine the correct `PYTHONPATH` for `pyext` taskgens + because the extension might be part of a Python package or used standalone: + + - When used as part of another `py` package, the `PYTHONPATH` is provided by + that taskgen so no additional action is required. + + - When used as a standalone module, the user needs to specify the `PYTHONPATH` explicitly + via the `pytest_path` attribute on the `pyext` taskgen. + + For details c.f. the pytest playground examples. + + +For example:: + + # A standalone Python C extension that demonstrates unit test environment population + # of PYTHONPATH and LD_LIBRARY_PATH/PATH/DYLD_LIBRARY_PATH. + # + # Note: `pytest_path` is provided
