4. See conflict

Description

Nuxt Studio causes de-sync between the page and the latest tracking github branch file version.

For example, my site that has this file as the latest commit on that branch is not the same as what was supposedly stored by Nuxt Studio on the latest commit deployed page (even after refresh, cookie clearing and all).

This is what Nuxt Studio thinks I have on the website deployment:

---
title: Vertex
date: 2025-07-09T00:00:00.000Z
description: A fast Obsidian-Flavored Markdown Editor for workspaces and single-files.
image: /projects/vertex/vertexmarkdowneditor-example.png
progress: alpha
tags:
  - markdown
  - markdown editor
  - vertex
  - ofm
  - obsidian
  - obsidian alternative
icon: i-tabler-markdown
showIssues: true
showWiki: true
repoUsername: CTRL-Neo-Studios
repoName: vertex
---

// rest of the content...

and this is what I have on my latest commit and what should be on the actual deployment of the site:

---
title: Vertex
description: A fast Obsidian-Flavored Markdown Editor for workspaces and single-files.
date: 2025-07-09T00:00:00.000Z

icon: i-tabler-markdown
progress: alpha
repository:
	showIssues: true

	repoUsername: CTRL-Neo-Studios
	repoName: vertex
tags:

  - ofm
  - obsidian
  - obsidian alternative
---

// rest of the content...

I use Vercel for the site deployment and the latest deployment is based off of my latest commit and on the correct branch.

Can there be an option to just resolve the conflicts directly on Nuxt Studio?

[Type-32]

Found a weird workaround: just delete the conflicted file and revert it.

Looking into the commit diffs:

It seems that when Nuxt Studio loads the markdown files, it tends to format it first, resulting in a different source than that of the original file in the latest github commit.

Something might be wrong with parsing.

// the rest...

This project originally started with me (@Type-32) trying to make a Rich-Text Markdown Editor that is compatible with [Obsidian-Flavored Markdown](https://help.obsidian.md/obsidian-flavored-markdown). The attempt [...]

// the rest...

Specifically with this part. At the link where I reference the obsidian-flavored-markdown, Nuxt Studio seems to parse it and replace the ")" character into ")" for no reason at all. When I changed it back and went to review the changes, it went from ")" to ");", and then in the commit here (CTRL-Neo-Studios/prism@a2e36c7) it was back to ")" and it went ahead and added another ";" at the end. What??

Hey @Type-32, can you share a simple reproduction so we can reproduce and fix this parsing issue?

Hi @larbish .
I seem to have a related set of symptoms.

1. The "Website" window has an empty line added on nearly every occasion where there is a newline. This was being picked up and reported as a conflict when I started writing this but is now NOT reported as a conflict even though the newlines are still being added.
2. Sometimes, the "Website" window shows spaces when there are newlines (text wrap) in the code. This is reported as a conflict.
3. For the first time, I now get an alert on pages saying "Formatting applied to align with MDC syntax standard.". This seems to coincide with a complete reordering of the frontmatter (and removal of line breaks). But there is no action to take (that I can find) and nothing can be edited.

I can add you to my repo if that would be helpful.

Hi @larbish ,

Sure thing, here's my repo: https://github.com/CTRL-Neo-Studios/prism

1. Pull the repo (the main branch)
2. Deploy it privately on Vercel
3. Open up any markdown file in Nuxt Studio, see the conflicts
4. "Resolve" conflict by deleting and revert the file deletion again, actually opening the file
5. Go to the Code Editor
6. Delete the character that I've shown in the screenshot right here: MDC parsing error #251 (comment)
7. Publish the changes
8. Find the commit that contains the changes in your forked GitHub repo
9. See the character ")" parsed into something else

Since I'm editing directly on my deployment, I'm not sure whether this issue exists in local. If this issue is related to nuxt/content#3549, then it would also probably exist in local development environments.

We're working on a new parser to ensure all those MDC parsing errors will be resolved.

WIP for integration of the new comark parser: #355
