用python给书单页面做一个图形化界面编辑工具

之前写过的一篇文章：为hexo博客Fluid主题添加书单是创建了一个书单页面来管理书籍，但是每次想插入新书的时候有点麻烦，要通过编辑index.md，并复制<li>标签中的内容来新加一本书。所以我想着能不能用Python搞个图形化界面来直接填写书籍内容，然后更新书籍。

所以以下Python文件除了tk，其他都不需要安装，直接终端运行就可以实现编辑了

import tkinter as tk
from tkinter import ttk, filedialog, messagebox

import shutil

class BookListManager:
    def __init__(self, root):
        self.root = root

        # 设置默认路径
        self.default_path = "/home/specialhua/specialhua/source/books"
        if not os.path.exists(self.default_path):
            self.default_path = "/home"
            
        # 设置默认备份路径
        self.default_backup_path = "/home/specialhua/Documents/books/books_md_backup"
        if not os.path.exists(self.default_backup_path):
            os.makedirs(self.default_backup_path)
        
        # 文件路径框架

图形化的界面如下：

在archlinux+hyprland下使用良好，于是接下来就可以创建desktop文件了：

a. 创建一个桌面入口文件 (book-manager.desktop)：

[Desktop Entry]
Name=Book Manager
Comment=Manage book list for hexo blog
Exec=/usr/bin/python3 /path/to/your/book_manager.py
Icon=text-editor
Terminal=false
Type=Application
Categories=Utility;

b.将此文件保存到 ~/.local/share/applications/ 目录下：

mkdir -p ~/.local/share/applications/
cp book-manager.desktop ~/.local/share/applications/
chmod +x ~/.local/share/applications/book-manager.desktop

以后再更新书籍的时候就可以免去编辑index.md的麻烦了~
