Currently I'm using pattern in vim.api.nvim.create_autocmd():

vim.api.nvim_create_autocmd({ "BufEnter", "BufFilePost" }, {
  pattern = { "*.tf" },
  callback = SetTerraformMappings,
  group = terraformGrp,
})

But I would prefer to use filetype somehow instead of pattern. In vimscript I could

autocmd Filetype terraform lua SetTerraformMappings()

Also as a workaround I can just create ~/.config/nvim/after/ftplugin/terraform.vim with the mappings there:

nnoremap <buffer> <leader>t :Shell terraform plan -out latest.tfplan<cr>
nnoremap <buffer> <leader>r :Shell terraform apply latest.tfplan<cr>

But I wonder, is there an equivalent to autocmd Filetype xxx yyy in lua nvim_create_autocmd()?

Note that filetype and pattern are not exactly equivalent because filetypes sometime inspect the contents of the file to do the filetype detection.

It is possible write is like this in lua, just use the FileType event.

(replace your file type, I don´t what is the correct one for terraform)

vim.api.nvim_create_autocmd( "FileType", {
  pattern = "yourfiletype",
  callback = SetTerraformMappings,
  group = terraformGrp,
})
