Did you update nvim or other plugins recently? I currently have no idea what's causing this or how to reproduce it 😞

I regularly update nvim and all of my plugins every few days. And I have a ton of plugins. So the possibilities are many

Any thoughts on what might have changed are appreciated. I haven't done anything to change this (intentionally) inside conjure. Are you on the develop branch?

Are you using stable Neovim or a nightly?

Unstable Neovim, master branch of Conjure

Off-hand, I can't think of any plugin I use that would potentially interfere with Conjure's ability to set the ft on its log buffer :thinking_face:

Okay, so you and the other person are using unstable Neovim. My hunch is that they introduced a breaking change I haven't noticed and haven't worked around yet.

I hope. If it's not that I'm at a loss.

I only ever use stable released Neovim versions, so I need to work out how to try unstable

Have you thought about running the various Neovim versions in CI and taking screenshots? (if such a thing is possible in CI)

Another thought: a local Dockerized setup could allow you to easily try other Neovim versions without having them installed on your machine

I've thought about adding integration tests before but not really across versions, I only target and support stable really right now. But could be worth looking into one day.

I think there's a cli that lets you swap nvim versions easily

Some community tool

I'll look around, mostly concerned at how I've missed a breaking change this big

I don't even set the file type or anything

I just set the file extension

That's all. So how has THAT stopped working... maybe a bug with floating windows...

Ohh, yeah. In light of that, this bug is super weird

Conjure isn't even in the business of setting ft=whatever, it's just using file extensions

Yup!

Neovim should be setting the ft correctly based on the extension, but in this case, it's not

If I do :e /tmp/foo.cljc, that works fine, and it sets ft=clojure

Could be related to floating windows?

I was seeing the ft not getting set in the floating window, and then when I pressed <localleader>lt to bring up the log "full screen," the ft still wasn't set. I wonder if the fact that it initially appears as a floating window is important

My hunch too, will have to look soon, will only get more people running into this, especially if they don't fix it and it is a Neovim bug. I wonder if nvim has any open issues

If I do :e while viewing the Conjure log buffer, the buffer empties out, and the ft is still not set. For whatever that's worth

Kinda smells like this to me https://github.com/neovim/neovim/pull/19216 There's an option you can set to use the legacy filtype.vim file. No idea why the .lua version would work differently, maybe it is a bug and we're the first to notice it but I find that unlikely. I can't see any issues on the nvim github that sound like this :thinking_face:
