hfcca 1.5.0

source_analyzer is a simple code complexity source_file_counter without caring about the C/C++ header files. It can deal with C/C++/Objective C & TNSDL code. It count the NLOC (lines of code without comments), CCN (cyclomatic complexity number) and token count of _functions.

#Header Free Cyclomatic Complexity Analyzer
[](https://travis-ci.org/terryyin/hfcca)

This tool will calculate the cycolomatic complexity of C/C++/Objective C code without caring about header files and preprocessors. So the tool is actually calculating how complex the code 'looks' rather than how complex the code 'is'.

People will need this tool because it's often very hard to get all the include folders and files right with a similar tool, but we don't really need that kind of accuracy when come to cyclomatic complexity.

##Installation

hfcca.py is only a single python file, you can always use it without install.

If you want a proper install:

<pre>
[sudo] pip install hfcca
</pre>

Or if you've got the source:

<pre>
[sudo] python setup.py install
</pre>

##Usage

<pre>
hfcca [options] [PATH or FILE] [PATH] ...
</pre>

hfcca (verion 1.5) is a simple code complexity counter without caring about
the C/C++ header files. It can deal with C/C++/ObjectiveC & TNSDL code. It count the NLOC
(lines of code without comments), CCN (cyclomatic complexity number) and
token count of functions.

It requires python2.6 or above (early versions are not verified).

<pre>
Options:
-h, --help show this help message and exit
-v, --verbose Output in verbose mode (long function name)
-C CCN, --CCN=CCN Threshold for cyclomatic complexity number warning.
functions with CCN bigger than this number will be
shown in warning
-w, --warnings_only Show warnings only
-i NUMBER, --ignore_warnings=NUMBER
If the number of warnings is equal or less than the
number, the tool will exit normally, otherwize it will
generate error. Useful in makefile when improving
legacy code.
-x EXCLUDE, --exclude=EXCLUDE
Exclude data files that match this regular expression
-X, --xml Generate XML in cppncss style instead of the normal
tabular output. Useful to generate report in Hudson
server
-p, --preprocess Use preprocessor, always ignore the #else branch. By
default, source_analyzer just ignore any preprocessor
statement.
-a ARGUMENTS, --arguments=ARGUMENTS
Limit for number of parameters
-P, --no_preprocessor_count
By default, a #if will also increase the complexity.
Adding this option to ignore them
-t WORKING_THREADS, --working_threads=WORKING_THREADS
number of working threads. The default value is 1.
