resolve vite.config.ts in parent directory

[pinage404]

Hi,

Describe the bug

Markdown-it plugin seems to not work when the slides.md file is in a subfolder

Minimal reproduction

Steps to reproduce the behavior:

I did a minimal reproductible test repository https://gitlab.com/pinage404/slidev_bad_subfolder_behavior/-/commits/main/?ref_type=HEADS

1. having the slides.md file in a subfolder

   slidev build ./subfolder/slides.md

2. with this content in the slides.md

   Normal ^sup^ normal

3. add markdown-it plugin

With [email protected], plugin works
With [email protected], the build works but the plugin seems ignored
With [email protected] (current latest), same behavior as 0.49.11

Alternative solution

Moving the slides.md in the root folder fix it

Additional context

I noticed the backward incompatibility on this slide (the corresponding code)

Environment

• Slidev version: 0.49.11 and newer
• Browser: not relevant, it fails event when building Firefox 128.0.2 (64-bit)
• 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).

It was really long and hard to isolate the problem, good luck with this one

Sorry, I can't see the content of your vite.config.ts. GitLab says 404 NotFound

Weird, it works for me

Here is the content

import MarkdownItSup from 'markdown-it-sup'
import { defineConfig } from 'vite'

export default defineConfig({
    slidev: {
        markdown: {
            markdownItSetup(md) {
                md.use(MarkdownItSup)
            },
        },
    },
})

It seems that the vite.config.ts hasn't been run. Move the vite.config.ts to the subfolder (next to slides.md) can fix this. Let's keep this issue open so that we can improve the behavior of the detection of "user root".

It used to work in 0.49.10 and below

I imagine that 0.49.11 introduces a behavior change

Thanks, i did a symlink in the subfolders this fix the issue
