Hello I don't know why this was turned into a discussion, but to reproduce this issue please

Clone this repo https://github.com/louiss0/zed-asciidoc-extension

Then try to install the extension as a dev extension!

I was using this kind of computer!

OS:       Microsoft Windows 11 Home (Build 26100)
Kernel:   MSYS_NT-10.0-26100 3.6.4
Host:     DESKTOP-O018JMQ
Shell:    /usr/bin/bash 5.2.37(1)-release

CPU:      Intel(R) N95
GPU:      Intel(R) UHD Graphics
RAM:      8.00 GB

Just so you know, this is the only asciidoc plugin for zed currently: https://github.com/andreicek/zed-asciidoc

And it's not clear whether the developer still maintains it.

I have forked it and may become maintainer: https://github.com/AMDphreak/zed-asciidoc

He doesn't maintain it. I created my own because of this.

@AMDphreak If you want to be the maintainer that's fine. But you should look into the parser I created. https://github.com/louiss0/tree-sitter-asciidoc

I see your parser. I got in touch with the repo owner for asciidoc-zed. He's willing to transfer the repo to someone else. Do you want to be the primary maintainer for this?

@AMDphreak If you want to be the maintainer that's fine. But you should look into the parser I created. https://github.com/louiss0/tree-sitter-asciidoc

I see your parser. I got in touch with the repo owner for asciidoc-zed. He's willing to transfer the repo to someone else. Do you want to be the primary maintainer for this?

I don't see the point, I already made my own repo. It has better code. Either the parser is broken or my computer is.

I'm sorry for not doing a proper issue! I think it's best to try to install the extension by using different computers!
