error after making modifications or otherwise leaving insert mode

[samf]

When I run with autocmd FileType * AnyFoldActivate in my vimrc, I get the following error after modifying the buffer:

Error detected while processing InsertLeave Autocommands for "<buffer=1>"..function <SNR>103_ReloadFolds:
line   38:
E111: Missing ']'

This has started happening only recently. Strangely, you haven't modified vim-anyfold recently. I've tried removing each of my other plugins in turn, and the problem remains. Perhaps a newer version of vim is causing this?

I should have mentioned: my current vim is version 8.2.1350.

If I comment out line 496:

let b:anyfold_commentlines[changed[0]-1 : changed[1]-1] = s:MarkCommentLines(changed[0], changed[1])

then the problem goes away.

But it looks to me like your [s match with your ]s. I can't see the flaw, but I don't speak vim either. Again, maybe the problem is not in your code, but in recent versions of vim itself.

Interesting and weird. You're using a very recent version of vim (2 days old) so I just hope this is going to be fixed in Vim soon. I looked for vim issues related to list slicing and I found this and this. So it seems that list slicing does not work unconditionally in vim.

Confirming that I'm also receiving this error, also version 1350. Reverting to version 1300 fixes it for me.

Looks like 1400 (released today on Mac Homebrew) fixes it. 😄

Thanks a lot for letting me know, this can be closed then.
