Analyzing C source code with python to compile statistics

Code Analysis

Analyzing C source code with python to compile statistics. The aim is to push these statistics to Graphite/Grafana for visualization.

Using pycparser to parse the code. The code in utils/fake_libc_include is Copyright (c) 2008-2017, Eli Bendersky All rights reserved. Licensed under the 3-clause BSD license in that folder.

Currently following stats are extracted:

max_nesting_depth	The maximum number of nested scopes (if, for, while...) in the code
avg_max_nesting_depth	The average deepest nesting level of functions
average_nesting_depth	Average nesting level of a code line
funcs_with_statics	The count of functions with static variables. To be represented as a ratio of all functions
function_count	Number of defined functions within the source
average_function_length	Average length of a function
average_function_params	Average number of parameters per function
average_variable_count	Average number of variables in a function. Excluding constants and loop variables
global_vars	Number of non-constant static or extern global variables
extern_vars	Number of non-constant extern variables
file_count	Number of files prcessed
functions_without_params	Number of functions without any parameters
functions_with_many_params	Number of functions with over 4 parameters
long_functions	Number of long functions
really_long_functions	Number of really long functions
