Asynchronous Lint Engine for Vim/NeoVim
ALE (Asynchronous Lint Engine) is a plugin for providing linting in NeoVim and
Vim 8 while you edit your text files.
ALE makes use of NeoVim and Vim 8 job control functions and timers to run linters
on the contents of text buffers and return errors as text is changed in Vim.
This allows for displaying warnings and errors in files being edited in Vim before
files have been saved back to a filesystem.
In other words, this plugin allows you to lint while you type.
