+ \c senfutil helps setting up projects which utilize SENF. It will configure all necessary
+ compiler and linker options and additionally sets up some useful defaults and utilities.
+
+ \c senfutil really serves three roles
+
+ \li detect SENF and configure the build accordingly
+ \li make some SCons extensions used within SENF available to other projects
+ \li set default compilation options in the same way, they are set when compiling SENF proper.
+
+ The last two points are of course optional.
+
+ \section senfutil_tutorial Tutorial
+
+ To utilize \c senfutil you need to do two things:
+ \li Update your \c SConstruct file
+ \li add a bootstrap \c senfutil.py to \c site_scons
+
+ Lets start with the \c SConstruct file
+ \code
+ import senfutil
+
+ env = Environment()
+ senfutil.SetupForSENF(env)
+ senfutil.DefaultOptions(env)
+
+ env.SetDefault(
+ PROJECTNAME = 'Example project',
+ PROJECTEMAIL = 'developer@domain.com',
+ DOCLINKS = [ ('Homepage', 'http://www.domain.com') ]
+ )
+
+ sources, tests = senfutil.Glob(env, exclude=['main.cc'])
+
+ objects = env.Object(sources)
+ example = env.Program('example', objects + ['main.cc'])
+ test = env.BoostUnitTest('test', objects + tests)
+
+ env.Default(example)
+
+ senfutil.Doxygen(env)
+
+ senfutil.CleanGlob('all', [ '*~', '#*#' ])
+ \endcode
+
+ This simple sample already enables a lot of functionality:
+ \li support for different \e SENF flavors (debug/normal/final)
+ \li support for different \e build flavors (debug/normal/final)
+ \li sensible default compile options for the different flavors
+ \li support for extended command-line variables
+ \li building documentation with an auto-generated Doxyfile
+ \li running unit-tests
+ \li cleaning backup and temporary files
+
+ Here a very quick rundown of the important scons commands:
+ \li Build default target:
+ <pre>
+ $ scons
+ </pre>
+ \li Build documentation and unit-tests:
+ <pre>
+ $ scons doc test
+ </pre>
+ \li clean up everything
+ <pre>
+ $ scons -c all
+ </pre>
+ \li Pass custom options on the command-line
+ <pre>
+ $ scons CXXFLAGS+=-Wextra
+ </pre>
+
+ Since \c senfutil.py is not on the standard \c python or \c SCons path, some extra steps are
+ needed to find it.
+ \li Either add the possible directories to <tt>sys.path</tt> before importing \c senfutil:
+ \code
+ import sys
+ sys.path.extend(('/usr/local/lib/senf/site_scons', '/usr/lib/senf/site_scons'))
+ import senfutil
+ \endcode
+ \li Alternatively, install the following utility script as <tt>site_scons/senfutil.py</tt> into
+ your project. This script will search for <tt>site_scons/senfutil.py</tt> in a list of
+ directories and then load the real \c senfutil.py on top of itself. The directories searched
+ include: the current directory and all parents, subdirectories named <tt>senf/</tt>,
+ <tt>Senf/</tt> or <tt>SENF/</tt> thereof, and <tt>/usr/local/lib/senf/</tt> and
+ <tt>/usr/lib/senf/</tt>
+ \include senfutil.py
+
+ \section senfutil_features
+
The \c senfutil utility for SCons helps setting up a project to compile against SENF:
\li \c senfutil adds all necessary libraries to link against
\li \c senfutil will set necessary compile options.
\li \c senfutil supports normal, debug and final project build options
+ \li \c senfutil adds support for Boost unit tests
+ \li \c senfutil implements a very simple to use enhanced doxygen build with SENF symbol
+ cross-reference
\li \c senfutil allows specifying variables on the scons command line
\li \c senfutil supports more readable compile-time SENF loglevel configuration
CXXFLAGS_final = [ '-O2' ],
CXXFLAGS_normal = [ '-O0', '-g' ],
CXXFLAGS_debug = [ '$CXXFLAGS_normal' ],
-
+
LINKFLAGS_normal = [ '-Wl,-S' ],
LOGLEVELS_debug = [ 'senf::log::Debug||VERBOSE' ],

- env.Default(
- env.Program( target='udpforward', source=glob.glob('*.cc') )
+ PROJECTNAME = 'Example project',
+ PROJECTEMAIL = 'developer@domain.com',
+ DOCLINKS = [ ('Homepage', 'http://www.domain.com') ]
)
+
+ # Create a list of sources and tests. Sources are all *.cc files, test are *.test.cc
+ sources, tests = senfutil.Glob(env, exclude=['main.cc'] )
+
+ # Build objects from sources
+ objects = env.Object(sources)
+
+ # Build main binary
+ env.Default( env.Program( target='example', source=objects + ['main.cc'] ) )
+
+ # Build a boost unit-test from additional test sources
+ env.BoostUnitTest( 'test', source=objects + tests)
+
+ # Build a documentation, autogenerates a Doxyfile
+ senfutil.Doxygen(env)
\endcode
This example builds a simple binary from a number of source files (all '.cc' files). It links
select one of the build configurations 'debug', 'normal' or 'final'. The following variables are
supported each with separate values for all three configurations:
- \li \c CXXFLAGS
+ \li \c CXXFLAGS
\li \c CPPDEFINES
\li \c LINKFLAGS
\li \c LOGLEVELS
where \e optional_stream and \e optional_area are optional fully scoped C++ names (e.g. \c
senf::log::Debug) and \e level is the loglevel. There must be \e no whitespace in a single
specification, multiple specifications are either specified using an array or separated with
- whitespace.

+ env.BoostUnitTest( 'test', source=objects + tests)
+ senfutil.Doxygen(env)
+ \endcode
+
+ \section senf_senfutil_tests Building unit tests
+
+ Building unit tests mostly follows a standard pattern
+
+ \code
+ # Generate list of sources and tests (sources=*.cc, tests=*.test.cc)
+ extra_sources = ['main.cc']
+ sources, tests = senfutil.Glob(env, exclude=extra_sources)
+
+ # Build object files needed for both main target and unit tests
+ objects = env.Object(sources)
+
+ # Build main target, e.g. a Binary with additional sources which are not part of the unit test
+ env.Program('example', objects+extra_sources)
+
+ # Build unit tests including additional test sources
+ env.BoostUnitTest('test', objects+tests)
+ \endcode
+
+ It is important to exclude the \c main function from the unit-test build since the boost unit
+ test library provides it's own.
+
+ \section senf_senfutil_doxygen Building documentation
+
+ Documentation is built using the \c senfutil.Doxygen utility
+
+ \code
+ env.Append( PROJECTNAME = "Example project",
+ PROJECTEMAIL = "coder@example.com",
+ COPYRIGHT = "The Master Coders",
+ DOCLINKS = [ ('Homeage', 'http://www.example.com') ],
+ REVISION = 'r'+os.popen('svnversion').read().strip().lower() )
+
+ senfutil.Doxygen(env)
\endcode
+ The \c senfutil.Doxygen utility autogenerates a \c Doxyfile.
+
+ The utility will search for a SENF documentation in the \c senfdoc and \c %senf subdirectories
+ as well as via the senfutil module directory and some other standard locations. If SENF
+ documentation is found, the SENF tagfiles will automatically be added. Links will be resolved
+ to the documentation found.
+
+ \c senfutil.Doxygen takes some additional optional keyword arguments:
+ \li \c doxyheader: Path of an alternative HTML header
+ \li \c doxyfooter: Path of an alternative HTML footer
+ \li \c doxycss: Path on an alternative CSS file
+ \li \c mydoxyfile: If set to \c True, don't generate or clean the \c Doxyfile\
+ \li \c senfdoc_path: List of additional directories to search for SENF documentation
+

\li The \c graphviz library (http://www.graphviz.org)

size of each single file.
