Plugin for EFM-compatible output.

Project description

A plugin for flake8 to print output in a format compatible with Vim’s errorformat (efm).

This lets other tools pick up flake8 errors and identify them as error/warning/etc.

Designed for efm-langserver, but should work on any tool that expects a similar format.

Usage

For usage via nvim-lspconfig + efm-langserver use:

local flake8 =  {
  -- Requires flake8-efm
  lintCommand = "flake8 --format efm --stdin-display-name ${INPUT} -",
  lintStdin = true,
  lintIgnoreExitCode = true,
  lintFormats = {
    "%f:%l:%c:%t:%m",
  }
}

Details

The default error format of flake8 shows an error code and a message, but there’s no obvious way to determine if something is an error or a warning. This is especially true for third-party codes.

For now, the leading code of each letter is mapped to an error level (error/warning/etc). There’s support for _some_ third-party plugins, and patches for others are most welcome.
