Error detected while processing BufWritePost Autocommands for "<buffer=X>"

[ravexina]

Does this bug happen when you install plugin without vim-polyglot?
No

Describe the bug:
While trying to save a newly created Html file, vim saves the file but also gives these errors:

"test.html" [New] 1L, 15C written
Error detected while processing BufWritePost Autocommands for "<buffer=1>":
E492: Not an editor command: ++once call polyglot#detect#Html()

To Reproduce:

• Open vim.
• :e test.html
• Write something in the buffer.
• :w

Additional data:

• I just updated vim-polyglot.
• I tried disabling all other plugins and I got the same result.
• VIM - Vi IMproved 8.1

I don't get this error. Do you get it with vim 8.2?

[sheerun]

Hmm I think you're using vim before patch 8.1.1113 at which ++once was introduced, I'll fix this

[sheerun]

94ec9c3 should have fixed this

[ravexina]

Thanks for your response.

I'm actually using version 8.1.1401 (The default version on Debian Buster's stable repository).

Included patches: 1-875, 878, 884, 948, 1046, 1365-1368, 1382, 1401

After updating vim-polyglot I'm still getting the errors. However with vim version 8.1.2269 and patches 1-2269 I don't get any errors.

huh sorry, I've refactored half of the code to be able remove, but not removed ++once. It should be fixed now

vim version: 8.2.1783.
when save twice, command line will echo current line:

:au BufWritePost

filetypedetect  BufWritePost
    <buffer=2>
              | call polyglot#detect#Html()

[sheerun]

I took different approach which should work, and should work even for Vim with tiny features set

Tks.
