使用python 正则导出ino文件中的函数声明

• 在一个单独文件夹中建立此python文件，并将ino文件拖入文件夹中
• 运行前需对ino文件进行格式化

import re
from pathlib import Path


# 查找路径下所有ino文件
def find_all_ino(dirs='.'):
    files = []
    # 过滤规则
    filter_rulers = ["*.ino"]
    for filter in filter_rulers:
        for dir_cur in dirs:
            p = Path(dir_cur).rglob(filter)
            for i in p:
                # print(i)
                # 获取地址字符串
                file_path = str(i)
                # 地址转义
                new_file = "\\".join(file_path.split("\\"))
                files.append(new_file)
    return files


def get_function_declaration(str_in):
    regex = r"(^[a-zA-Z_]+\s+[a-zA-Z_]+\(.*\))\s+\{"

    functions = []

    matches = re.finditer(regex, str_in, re.MULTILINE)

    for matchNum, match in enumerate(matches, start=1):

        # print("Match {matchNum} was found at {start}-{end}: {match}".format(
        #     matchNum=matchNum, start=match.start(), end=match.end(), match=match.group()))

        for groupNum in range(0, len(match.groups())):
            groupNum = groupNum + 1

            # print("Group {groupNum} found at {start}-{end}: {group}".format(groupNum=groupNum,
            #       start=match.start(groupNum), end=match.end(groupNum), group=match.group(groupNum)))
            functions.append(match.group(groupNum))

    return functions

# 将列表存为文件
def save_list_to_file(list_in, file_name):
    with open(file_name, 'w') as f:
        for item in list_in:
            f.write("%s;\n" % item)


if __name__ == '__main__':
    print("Start")
    ino_files = find_all_ino()

    file_path = ino_files[0]
    str_in = Path(file_path).read_text(encoding='utf-8')
    functions = get_function_declaration(str_in)
    save_list_to_file(functions, "functions.txt")
    print("Done !")
