vimindent variable is not defined about vim HOT 3 OPEN

This is vim9 script. That is currenntly only valid when evaluating from within vim9 script context. I think it was discussed before, that one cannot easily call exported vim9 functions.

from vim.

I see. Thank you for clarifying. Problem seems to be that when older plugins check indentexpr for a vim filetype, they will run into the same undefined var issue.

Example: https://github.com/Thyrum/vim-stabs

If you load this plugin, edit a *.vim file, and toggle on autoindent, you get the same error

So the function is being called outside of the vim9 script context all the time

from vim.

To prevent described error, I guess instead of

setlocal indentexpr=dist#vimindent#Expr() should be used.

from vim.
