Auto Punctuation & Bracket Helper 是一款面向中英文混合输入场景的浏览器输入辅助扩展。它可以在输入过程中自动将常见中文标点转换为对应的英文标点，并提供括号、引号自动配对及选中文本包裹功能，减少频繁切换输入法或手动补全符号的操作。 主要功能： • 中文标点自动转换 在普通输入框、文本区域和常见富文本编辑区域中，将中文输入法产生的标点转换为对应的英文标点，例如将“，”转换为“,”、“。”转换为“.”、“（”转换为“(”。 • 括号与引号自动配对 输入左括号或左引号时，自动补充对应的右侧符号，并将光标放置在符号中间。支持圆括号、方括号、花括号、单双引号和尖括号等常见符号。 • 包裹选中的内容 选中一段文字后输入左括号或引号，扩展会自动在选中内容两侧添加对应符号。对于富文本内容，会尽量保留原有的粗体、链接和其他文字格式。 • 快速删除空符号对 当光标位于一对空括号或空引号中间时，按一次退格键即可同时删除左右两个符号。 • 避免重复输入右侧符号 如果光标后方已经存在对应的右括号或右引号，再次输入该符号时，扩展会将光标移动到符号后方，而不会重复插入。 • 中文输入法兼容 扩展会等待中文输入法完成拼音组合和选词后再处理标点，尽量避免干扰输入法的正常输入过程。 • 灵活的网站使用范围 默认情况下，扩展会在所有可访问的网站上启用。用户可以添加排除规则，使扩展不在指定网站运行；也可以切换为“仅在列表中的网站启用”模式。 网站规则支持： • 精确域名匹配 • 域名及其子域名匹配 • 域名关键词匹配 适合以下使用场景： • 经常使用中文输入法编写英文内容 • 编写程序提示词、技术文档或双语资料 • 希望减少中英文标点混用 • 经常需要输入括号、引号或包裹选中文本 • 希望在不同网站上保持一致的输入体验。 Auto Punctuation & Bracket Helper is a browser typing assistant designed for users who frequently switch between Chinese and English input. It automatically converts common Chinese punctuation into corresponding English punctuation while you type. It also pairs brackets and quotes, wraps selected text, and helps prevent duplicate closing characters. Key features: • Automatic punctuation conversion Converts common Chinese punctuation into English punctuation in regular text fields, text areas, and common rich-text editing areas. For example, “，” becomes “,”, “。” becomes “.”, and “（” becomes “(”. • Automatic bracket and quote pairing When you enter an opening bracket or quote, the extension inserts the matching closing character and places the cursor between them. Common parentheses, square brackets, braces, quotes, and angle brackets are supported. • Wrap selected text Select some text and enter an opening bracket or quote to place the matching characters around the selection. Rich-text formatting such as bold text and links is preserved whenever possible. • Delete empty pairs When the cursor is positioned between an empty pair of brackets or quotes, pressing Backspace removes both characters at once. • Skip existing closing characters If the matching closing character already appears immediately after the cursor, typing it again moves the cursor past it instead of inserting a duplicate. • Chinese input method compatibility The extension waits for IME composition and candidate selection to finish before converting punctuation, reducing interference with Chinese input methods. • Flexible site controls By default, the extension is active on all supported websites. You can exclude specific websites or switch to a mode where the extension runs only on listed websites. Site rules support: • Exact domain matching • Domain and subdomain matching • Domain keyword matching Useful for: • Writing English content with a Chinese input method • Creating prompts, technical documents, or bilingual content • Avoiding mixed Chinese and English punctuation • Frequently entering brackets, quotes, or wrapped text • Maintaining a consistent typing experience across websites
