Describe the bug
Line break is ignored in code block.
with parseInline()

To Reproduce

// Example of code
console.log("Hello world!");
```

converted to

Expected behavior
<code>// Example of code

Are you using parseInline() in a custom extension? In general, parseInline() only handles single lines of content. If you want to parse the whole code block including line breaks, use parse(). Similarly, you probably want to make sure your Tokenizer is using this.lexer.blockTokens instead of this.lexer.inline.

If you want to share your extension code so far we can take a look and provide tips to get you unstuck.

I am using parseInline().
I need to output only these tags:
<b>
<i>
<u>
<s>
<del>
<a>
<code>

[calculuschild]

Could you provide the entire code you have tried for your extension so far?

[nmime]

just used parseInline ;)

As @calculuschild said parseInline is for inline content only. Fenced code block are block content. This looks like it is working as expected.

[nmime]

ok, how can get output with only specified tags?

[UziTech]

You can create a tokenizer that is a noop for any tokens you don't want.

Something like:

const tokenizer = {
  heading() {},
  hr() {},
  blockquote() {},
  list() {},
  table() {},
  lheading() {}
};
marked.use({tokenizer});

[nmime]

I passed like that

    fences() {},
    heading() {},
    hr() {},
    blockquote() {},
    list() {},
    def() {},
    table() {},
    lheading() {},
    paragraph() {}

this helped, but how to remove the <p> at the beginning and end?

[UziTech]

If you are parsing as block tokens every token has to be in a block token. The easiest way to remove them is just to remove them after running through marked.

let html = marked.parse(markdown);
html = html.replace(/^\s*<p>([^]*)<\/p>\s*$/, "$1");

Keep in mind that html is valid markdown so if you actually do not want to allow someone to output <p> tags you will have to use some other library like dompurify to remove them.
