Autocommand not working with ChkTeX

[tarsobcaldas]

I'm trying to get the autocommand to work in my lua config with

require('lint').linters_by_ft = {
	tex = {'chktex'}
}

and

vim.cmd([[au BufWritePost <buffer> lua require('lint').try_lint()]]) 

but it's not working. When I run only lua require('lint').try_lint on a .tex buffer, it works, but the autocmd doesn't.

I'm using Windows 11 with Neovim 6.0. I'm trying to build a lua only neovim config, so I'm not using .vimrc or any .vim file. Will try though, if anything else fails.

Where do you run vim.cmd([[au BufWritePost <buffer> lua require('lint').try_lint()]]) ? If it is only set once in the init.lua it will only be triggered once on initial startup. The <buffer> in the autocmd definition means it will only apply for the current buffer at the time the vim.cmd call is made.

You can either remove the <buffer> or make sure you setup the BufWritePost autocmd on each buffer

I was facing the same issue but with pylint. When writing

vim.cmd([[ au BufWritePost <buffer> lua require('lint').try_lint() ]])

in my init.lua the linter was never triggered, but when I ran au BufWritePost <buffer> lua require('lint').try_lint() manually at an opened file it worked.

Following @mfussenegger's explanation, I replaced the previous line with

vim.cmd([[ au BufWritePost * lua require('lint').try_lint() ]])

and now the linter is automatically called whenever I write at any buffer.

Substituted for BufRead,BufWritePost and it now works as I expected. Thanks!
