Added script to replace strings, respecting WMC_TOOL_SKIP

#!/bin/python3

import argparse

import re

parser = argparse.ArgumentParser(description='Substitute strings in files, skipping blocks in WMC_TOOL_SKIP')

parser.add_argument('input',type=str,help='C source file')

parser.add_argument('target',type=str,help='Target string to replace')

parser.add_argument('dest',type=str,help='Destination string to insert')

args = parser.parse_args()

fileIn  = args.input

target  = args.target

dest    = args.dest

skip = 0

with open(fileIn, 'r') as f_in:

    lines = f_in.readlines()

with open(fileIn, 'w') as f_out:

    for line in lines:

        if re.search(r'#define\W+WMC_TOOL_SKIP', line):

            skip = 1

        elif re.search(r'#undef\W+WMC_TOOL_SKIP', line):

            skip = 0

        else:

            if not skip:

                line = re.sub(r'\b%s\b' % (target), '%s' % (dest), line)

        f_out.write(line)

 No newline at end of file
