When I type "[", a "\" appears before "[" in the markdown source code

Initial checklist

• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Affected packages and versions

7.3.3

Link to runnable example

No response

Steps to reproduce

当我输入[的时候，[的前面会出现一个多余的\。

导致无法使用 Link和 Img，因为Link和Img是[开头。在官方的Playgroud中也出现了这个现象

eg:
当我输入

[百度](http://www.baidu.com/)

在md源码中会被解析成

\[百度]\(http\://www\.baidu.com/)

最终导致Link无法显示

Meeting the same problem, cannot type any links.

Same here.

@Saul-Mirone do you have a plan/idea how to fix this?

[ravi-ojha]

Same issue (but trailing slash) with using Shift+Enter and then typing anything.

Edit: Found syntax-tree/mdast-util-to-markdown#45
It looks intentional for this trailing slash. Although, this is not standard markdown syntax.

I'm seeing this as well. If I include a [ in the initial value, it is parsed correctly and links work. But if a [ is typed into the editor, it is escaped with \. This means links are impossible to create in the editor, including in the Playground.

I've tested that this issue was introduced in 7.3.3 and still exists in 7.3.6. Reverting to 7.3.2 resolves the problem.

That part was extracted as @milkdown/plugin-automd. You can install the plugin and enable it.

Is the escaping of square brackets intentional, or is it a bug that will be resolved at some point? I'm writing a plugin for wiki links, which uses square brackets. Is the expectation that I need to write an InputRule that removes escaped brackets?

Is plugin-automd now required for commonmark support? It doesn't appear to be documented, but links no longer work with the commonmark preset alone.

1. The escaped brackets is introduced by remark, it will add escape mark to squre bracket to make sure the brackets won't be parsed as links.

2. If you really want to inseart a link instead of bracket, there're a lot of methods to do that. For example, an inputrule should be created to convert patterns like [\w+](\w+) into links. You can also use a shortcut to add link to the selected text.

3. For plugin-automd. It tries to reparse everything in user input and it will introduce other issues. So I split it out from preset-commonmark to let users to decide if they need to use it. I plan to add another inputrule for links but I just didn't get time to do that. I'm working on the @milkdown/components and @milkdown/crepe libraries.

@Saul-Mirone
Thank you! I took your advice and added @milkdown/plugin-automd, then enabled it, which fixed the problem.
