-Tool Description
-================
-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=<rule>' 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.
