Is there a way to write a file and skip the autocmd on write?

Question

My .vimrc has,

autocmd FileType rust autocmd  BufWritePre <buffer> call LanguageClient#textDocument_formatting_sync()

This works great, unless my LanguageClient crashes. Then I can't write the buffer. Is there an easy method to write a file and skip the autocmd, you'd think :w! but alas, even that is blocked by autocmd

Answer 1

Generally speaking, that's exactly what the :noautocmd command modifier is for. Just prefix your command with that and all autocommands should be disabled for just the run of that command.

:noautocmd w

Of course, this is the scorched earth approach. If there are other autocommands that you need to keep enabled and you're trying to ignore just the one you mentioned than a different approach is required. If this is the case I'd suggest explicitly mentioning it in your question, though there are few things I can mention right now...

First, want to see which, if any, autocommands are being run? Try this:

:9verbose w

Speaking for myself, I have two plugins that have actions that are triggered by an autocommand associated with :w. They aren't what I'd call critical but I may still want to keep them intact. They are not associated with BufWritePre, though, so for me an alternative to :noautocmd would be to disable just the BufWritePre event, do the write, then re-enable that event:

:set eventignore+=BufWritePre | w | set eventignore-=BufWritePre

That could easily be wrapped up in a mapping or user command.

Just ignore all errors from LanguageClient

silent! call LanguageClient#textDocument_formatting_sync()

Note: the last error message is still available as echo v:errmsg.
