Windows: CRLF line endings cause "Invalid frontmatter format" build error

[bit-png]

I followed the instructions to install Marmite and start making a blog on Windows. When serving this project with marmite --serve --watch myblog site in Windows, and editing a file in Visual Studio using its default line endings:

---
date: 2024-10-25
tags: hello,world
---

# Hello World
...

The following error appears:

INFO  marmite::site] Change detected. Rebuilding site...
ERROR marmite::site] Failed to process file myblog\hello-world.md: Invalid frontmatter format
INFO  marmite::site] Generated site\index.html

(All my test files used CRLF line endings, but the error only affected the ones with metadata.)

I can fix this within VS Code by switching the file's line endings from CR+LF to just LF, but this issue might need a fix or a note in the documentation for Windows users.

thanks for reporting, I don't have windows to test it, let's wait for a PR

It looks like the problem is with serving + watching.

Can you try building without those options?

marmite myblog site

Does that render the site correctly?

You can open the site directly in the browser to test.

Even when just compiling the site (using marmite blog static) it still causes the error message. Here's the full output:

(The custom.css/js errors can be ignored, as I've tested a slightly bigger blog with them and they seem to work fine.)

I think the error is from a library -- I see it coming from \frontmatter-gen-0.0.2\src\error.rs and \extractor.rs, because the latter searches for "---\n" when looking for data, and there is no such line ending on Windows-made files.
