compilepos = -1

    if compilepos != -1:
        compileFile = args[compilepos + 1]
        args.remove("--compile")
        args.remove(compileFile)

    ignorePatterns = []
    if ignoreFile is not None:
        print("IGNORING PATTERNS DEFINED IN", ignoreFile)
        with open(ignoreFile, 'r') as ignoref:
            for l in ignoref:
                ignorePatterns.append(l[:-1])
