If I open a file with the following extension .xtm (which uses Lisp style expressions) and try to edit, I get this error in neovim:
Error detected while processing function <SNR>100_indent:
line 6:
E117: Unknown function: ParinferIndent
This also happens only if I have 'timburgess/extempore.vim' installed. If I remove it there is no more problem. But I need extempore plugin to work with extempore.
I just added to my vimrc:
au BufNewFile,BufRead *.xtm let g:parinfer_mode = "off"
to avoid this error while waiting to know what's going wrong.
