Affected package
mdast-util-mdx@3.0.0
Steps to reproduce
Run the following script:
import { fromMarkdown } from 'mdast-util-from-markdown'
import { mdxFromMarkdown, mdxToMarkdown } from 'mdast-util-mdx'
import { toMarkdown } from 'mdast-util-to-markdown'
import { mdxjs } from 'micromark-extension-mdxjs'
let content = `
{
' This is fine'
}
<div>
{\`a
b
c
d\`
+ 'e'}
</div>
`
for (let count = 0; count < 10; count++) {
const tree = fromMarkdown(content, {
extensions: [mdxjs()],
mdastExtensions: [mdxFromMarkdown()]
})
content = toMarkdown(tree, { extensions: [mdxToMarkdown()] })
console.log(content)
}Actual behavior
Every iteration, the lines with b, c, d, and e get indented by 2 spaces. This is mostly inconvenient. There’s no way to format the MDX consistently. For multiline strings however, this changes the meaning of the content. The indentation spaces become part of the string after re-parsing.
Expected behavior
The expression isn’t indented.
