`}` in code block options

[pinage404]

Hi,

Describe the bug

slidev build fails after upgrade with Invalid end tag

Minimal reproduction

Steps to reproduce the behavior:

I did a minimal reproductible test repository https://gitlab.com/pinage404/slidev_broken_upgrade

With this content in a slides.md

<div>

```txt {editorOptions:{lineNumbers:'off'}}
git reset [--soft | --mixed [-N] | --hard | --merge | --keep] [-q]
```

<span v-mark.box>

```txt {editorOptions:{lineNumbers:'off'}}
[<commit>]
```

</span>

</div>

With [email protected], slidev build works With [email protected], slidev build fails stdout stderr With [email protected] (current latest), slidev build still fails stdout stderr

Additional context

I'm trying to upgrade this slide (the corresponding code)

Environment

• Slidev version: 0.49.17 and newer
• Browser: not relevant, it fails on the build
• OS: NixOS 24.05.20240725.a1cc729 (Uakari) x86_64

~~If you are using Slidev globally (i.e. npx slidev or npm i -g slidev), please try to reproduce the issue in a local project (i.e. npm create slidev@latest).~~ I prefer to have a reproductible setup, i avoid globally installed tools that are specific to a project

Thank you for maintaining slidev, it's an amazing project, that evolves really quickly, it's really enjoyable !

I am not sure about the usage of the options in your code. The options seem to be Monaco Editor options, but the code block is a normal code block.

To define a Monaco Editor:

```txt {monaco}{editorOptions:{lineNumbers:'off'}}
git reset [--soft | --mixed [-N] | --hard | --merge | --keep] [-q]
```

To define a code block without line numbers:

```txt {*}{lines:false}
git reset [--soft | --mixed [-N] | --hard | --merge | --keep] [-q]
```

However, the code block transformer does have some problems when there are } inside the option.

This is the way I found to disable it :shrug:

Thanks for your comment, it helped me find another solution

Should we close this issue ?

Let's keep the issue open to keep track of the problem of } inside the option. Thank you for letting us know this.
