-- Some linters require a file to be saved to disk, others support linting stdin input.
-- For such linters you could also define a more aggressive autocmd,
-- for example on the InsertLeave or TextChanged events.
-- To get the filetype of a buffer you can run := vim.bo.filetype.

-- lints on close, see autocmd
