原来写了个py脚本，用于重命名从qq音乐下载的米哈游的音乐（ogg、mp3、flac均有）
Python
import os
import re
# QQ音乐
prog = re.compile(r"(.*\\)(.*) - (.*)( \[.*\])(\..*)")
# 网易云
# prog = re.compile(r"(.*) - (.*)")
def concat(*args, sep=""):
return sep.join(args)
for curDir, dirs, files in os.walk(r"D:\LanguageLearning\python\music"):
for file in files:
# qq
if file[-5:] == "].mp3" or file[-5:] == "].ogg" or file[-6:] == "].flac":
# 网易
# if (file[-3:] not in {"exe",".py","cmd","bat"}):
name = os.path.join(curDir, file)
# print(name)
# print("")
# QQ
new_name_list = prog.split(name, 5)
new_name = (
'"' + concat(new_name_list[1], new_name_list[3], new_name_list[5]) + '"'
)
name = '"' + name + '"'
print(new_name)
# ---
# 网易
# new_name_list = prog.split(name, 2)
# print(new_name_list)
# new_name = os.path.split(os.path.realpath(__file__))[0] + "\\" + new_name_list[2]
try:
# qq
os.renames(name, new_name)
# 网易
# os.renames(name, new_name)
except: # noqa: E722
os.remove(name[1:-1])
print("Success!", end="\n\n")
邪门玩意，明明py3.10都没问题的，也没看着py更新了与文件重命名相关的函数啊，怎么自从更新到py最新版本3.12突然就寄了……
典型表现就是运行到一半突然卡住，也不报错，也不提示，也不崩溃。任务管理器python占用cpu：0%-0.4%（在我的电脑上很正常），内存长久无变化，调试了一番硬是没发现问题出在哪里……明明一切都完美运行，然后突然毫无征兆的，进度就卡死在那里了……真是邪门……
正好我对Python的运行效率头大很久了，Rust又不太会用，于是直接决定用自己不怎么熟悉的cpp直接重写一个……
得益于Cpp糟糕max的UTF8（CJK）支持，我从昨晚12点写到3点，又从今天11点写到刚刚终于弄明白了……本来咱就不咋会cpp，还得想着做CJK兼容……真是服了cpp了
好在最后自己憋出来了……累死，AI用了吗？如用。解答的东西狗屁不通，思路都不对……
放小众留个痕迹吧，万一以后我手贱删了还有地方找，也懒得上传github了
cpp
#include "locale.h"
#include "wchar.h"
#include <filesystem>
#include <iostream>
#include <regex>
#include <string>
#include <windows.h>
using namespace std;
using namespace filesystem;
int main() {
/*Set local of the rigion to avoid error caused by wrong coding*/
std::setlocale(LC_ALL, "en_US.utf8");
/*Init file path*/
path file_dir = L"(D:\\LanguageLearning\\python\\music)";
if (!exists(file_dir))
exit(1);
/*Start regex*/
wsmatch regex_result_group;
wregex reg(L"(.*\\\\)(.*) - (.*)( \\[.*\\])(\\.)(ogg|mp3|flac|wav)");
/*Start to enum the dir*/
directory_iterator list(file_dir);
for (auto &it : list) {
wstring temp = it.path().wstring();
/*if path could match the regex, set the new_name*/
if (regex_search(temp, regex_result_group, reg)) {
wstring result = regex_result_group[1].str() +
regex_result_group[3].str() + L"." +
regex_result_group[6].str();
wstring original_name = regex_result_group[0].str();
wstring brief_name = regex_result_group[3].str();
/*Try to rename*/
if (0 != _wrename(original_name.c_str(), result.c_str())) {
wcout << "Error" << brief_name << endl;
} else {
wcout << "Successfully! " << brief_name << endl << endl;
}
}
}
return 0;
}
（注：编译参数：-std=c++23 -Wall -Werror -O3 -pthread，请使用std23版本）
二编：
并且终于在大佬的分析下整明白了python为啥会崩（但是还是说上个版本没崩 
），大抵就是错误的引号导致的rename和remove函数崩溃
在ai的帮助下改用rust全面重写，彻底解决了cpp的中文传参问题（我就没整明白过）
三编
Rust重写了一点点，增加了一点奇怪的路径支持功能
四编，改了rust的一点点冗余
