How can I trigger the Auto import?

Language Server Protocol (LSP)

This is what I’m shown and it seems like hitting tab is not really doing the trick. Am I missing something bt any chance?

Hi @leanjunio,

I think what you are looking for is code_action which you have already mapped to <space>ca. So you can just put the cursor on the line having error and press <space>ca.Then you will be shown options to add the import and much more.

Any way to do it without having to choose? Just automatically choose like 1 or 2?

That will depend on the completion plugin you are using with lsp like completion.vim or nvim-compe. Depending on those, you have to make some config changes. Example: for compe, you just have to map compe#confirm and at the time of writing the needed term, just use that mapping to confirm. Pretty sure, it will be kinda same in completion too.
