问题详情

当在 rspress.config.ts 将 markdown.mdxRs 设置为 false 之后

会导致标题语法中的 链接 代码块 等语法前方的空格丢失

---

例如

所用 rspress.config.ts

import { defineConfig } from "rspress/config";

export default defineConfig({
    root: "src",
    markdown: {
        mdxRs: false,
    },
});

其中 src/index.md 为

# 一 [二三四五](https://www.baidu.com) 六七

渲染出来后 一 后方的空格丢失

---

当使用的 rspress.config.ts 为

import { defineConfig } from "rspress/config";

export default defineConfig({
    root: "src",
});

其空格正常显示

I think it's a bug about @mdx-js/mdx. Maybe this issue is solved in @mdx-js/mdx@3.0.1 since I tried in its playground.

Rspress now use the latest major 2 version of @mdx-js/*: 2.3.0. We will bump to V3 in the future, see https://github.com/web-infra-dev/rspress/discussions/1105#discussioncomment-9507488 for details.
