Hi, is this a known issue? perhaps it is something with my config, but I just uninstalled/re-installed the plugin and still seeing the below error when opening vim version 9.1.700

the error:

Error detected while processing /Users/billykern/.vimrc[13]..function plug#end[86]..script /opt/homebrew/Cellar/vim/9.1.0700/share/vim/vim91/filetype.vim[3167]../Users/billykern/.vim/plugged/vim-just/ftdetect/just.vim:

Not a known issue. Haven't seen this error here. And it's weird since line 8 of that file doesn't have any ) character at all 😕

How are you installing vim-just?

I don't currently have access to my main dev system to investigate in detail atm, but I believe my daily use Vim version is 9.1.516. Did this previously work for you? Did the issue occur when you updated Vim to a newer version?

[laniakea64]

Ok, back at my dev machine and started further investigation by looking at Vim commit history. It looks like Vim 9.1.700 maybe known to be problematic in this area. Can you try updating Vim to 9.1.702 or later? If not, can you try downgrading Vim to a version older than 9.1.700?

[laniakea64]

Can confirm this issue in Vim 9.1.700 and that this error does not occur in Vim 9.1.707. The error breaks case-insensitivity of filename matching: Vim 9.1.700 only matches all-lowercase. It also breaks detection of *.justfile User justfiles.

Since this Vim bug was fixed on Vim side (especially since they fixed it so quickly), it doesn't seem worth trying to work around it in vim-just, so closing this issue. @billykern , it might still be useful to know how you installed Vim and whether it's possible to install a working Vim version by that method?

Thanks for taking a look and confirming @laniakea64.

I installed vim with brew, I am not so familiar with the tool and don't see an easy way to change versions (tried brew edit vim to point to another one, but it keeps picking up 9.1.700 even if I --build-from-source on install/re-install)

they only update every 50 versions, but looking at commit history that should be somewhat soon...?

Looking at that link and at https://formulae.brew.sh/formula/vim , it looks like there maybe a "head" option that would get you 9.1.708 as of this writing?

[billykern]

you're right, thanks for explaining that, it worked ✅

Homebrew "stable" Vim version is now 9.1.750 so should no longer have this issue.
