我注意到你的HTML编译器代码有几个小问题，主要涉及自动补全功能未完成和部分逻辑错误。以下是修复建议：

### 主要问题修复：
1. **自动补全列表未定义**：
需要补全 `self.autocomplete_words` 列表，例如：

self.autocomplete_words = ['<html>', '<head>', '<body>', '<div>', '<p>', '<a>', '<img>', '<script>', '<style>', 'class', 'id', 'href', 'src']

复制代码

2. **文件对话框类型缺失**：
在 `open_file` 和 `save_as_file` 方法中补全文件类型：

filetypes=[('HTML 文件', '*.html'), ('所有文件', '*.*')]

复制代码

3. **回车缩进逻辑错误**：
修复 `handle_return` 的缩进计算：

def handle_return(self, event):
current_pos = self.text_area.index(tk.INSERT)
line, col = map(int, current_pos.split('.'))
line_text = self.text_area.get(f'{line}.0', f'{line}.end')
indent = 0
# 修正：遍历字符而非整个字符串
while indent < len(line_text) and line_text[indent] == ' ':
indent += 1
self.text_area.insert(tk.INSERT, '\n' + ' ' * indent)
return 'break' # 阻止默认回车行为

复制代码

### 其他优化建议：
1. **语法高亮增强**：
在 `highlight` 方法（未提供）中建议使用正则表达式匹配标签：
re.findall(r'<[^>]+>', content)

2. **临时文件清理**：
在 `run_html` 中添加延时删除临时文件：

import threading
import time
def delete_temp_file(path):
time.sleep(5) # 延迟5秒确保浏览器加载
os.remove(path)
# 在webbrowser.open后添加
threading.Thread(target=delete_temp_file, args=(temp_path,)).start()

复制代码

3. **自动补全框架**：
补全基础自动补全方法（需自行完善匹配逻辑）：

def check_autocomplete(self, event):
# 获取当前单词逻辑示例
current_pos = self.text_area.index(tk.INSERT)
words = self.text_area.get("1.0", current_pos).split()
if not words:
return
last_word = words[-1]
# 简单示例：匹配开头字符
matches = [w for w in self.autocomplete_words if w.startswith(last_word)]
if matches:
self.show_autocomplete(matches, current_pos)

复制代码

### 使用注意事项：
1. 确保语法高亮方法 `highlight` 已实现
2. 自动补全功能需要完善位置计算和选择逻辑
3. Windows系统可能需要调整临时文件路径处理

> 提示：你可以先注释掉自动补全相关的绑定事件（self.text_area.bind('<KeyRelease>', self.on_key_release)），优先确保基础功能运行正常。

需要进一步调试某个功能可以告诉我具体问题点，我会提供更详细的解决方案！

我去，这么狠的吗？

看了一下，这段代码其实是用 tkinter 做了一个简单的 HTML 编辑器，能新建、打开、保存、运行 HTML 文件，还带了点语法高亮和自动补全，操作起来比较方便。

下次发帖配点图片那就更好了，加油~
