Whether to enable https://github.com/mattn/efm-langserver

General purpose Language Server that can use specified error message format generated from specified command.

Requires at minimum EFM version v0.0.38 to support launching the language server on single files. If on an older version of EFM, disable single file support:

require('lspconfig')['efm'].setup{
  settings = ..., -- You must populate this according to the EFM readme
  filetypes = ..., -- Populate this according to the note below
  single_file_support = false, -- This is the important line for supporting older version of EFM
}

Note: In order for neovim’s built-in language server client to send the appropriate languageId to EFM, you must specify filetypes in your call to setup{}. Otherwise lspconfig will launch EFM on the BufEnter instead of the FileType autocommand, and the filetype variable used to populate the languageId will not yet be set.

require('lspconfig')['efm'].setup{
  settings = ..., -- You must populate this according to the EFM readme
  filetypes = { 'python','cpp','lua' }
}
