一个使用 GPT-5.5 和 以下提示 构建的实验性 Web Component：

let's build a Web Component for embedding code from GitHub

<github-code href="https://github.com/simonw/sqlite-ast/blob/437c759129154f05296324a7f82aa1246340dd14/sqlite_ast/parser.py#L9-L18"></github-code>

It takes URLs like that, converts them to https://raw.githubusercontent.com/simonw/sqlite-ast/437c759129154f05296324a7f82aa1246340dd14/sqlite_ast/parser.py, then uses fetch() to fetch them and displays the specified range of lines - with line numbers, no syntax highlighting though

Show me a preview web browser so I can see your work

以下是它嵌入到本页后的效果：
