Hi,

When opening html file in new buffer while my _vimrc is written in vim9script,

this message appears:

Messages maintainer: Bram Moolenaar

"~\Desktop\filetype.vim.html" 2315L, 216123B

Error detected while processing BufRead Autocommands for "*.html"..function dist#ft#FThtml[13]..FileType Autocommands for "html":

E1126: Cannot use :let in Vim9 script

IOW, a script (without vim9script in it) sourced from an autocommand
triggered from Vim9 script is erroneously interpreted as if it were
itself a Vim9 script.

Best regards,
Tony.

What is the line in the vimrc then?

The error points to the FThtml() function in
runtime/autoload/dis/ft.vim,
the command:
setf FALLBACK html

I guess there is an "au Filetype html" command that is triggered then,
but I can't reproduce a problem with that.

Hi Bram,

The only line I got grepping in all my Vim distribution is commented in _vimrc.

To reproduce just use the plugin GitHub - xavierchow/vim-sequence-diagram: A Vim plugin for previewing sequence diagram in a browser
Try generating sequence diagram by pressing <Leader>t onto a buffer diagram.seq containing these lines

title: some title
Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!

Thank you.

Solved by migrating this plugin from vimscript to vim9script (adding feature to auto open file in web browser on windows).
