I use eslint with ale to lint my Javascript code. After editing a code block, I often have a few errors to fix. Fixing is done by navigating to the next erroneous line, reading the problem from the ruler and fixing.
If I could skip the navigation phase and use a specific key binding to navigate to the location of the next error - its line, and hopefully its column - it would be great.
Is there a way to use key binding to navigate to the next lint/ale error?
ALE has many commands that can navigate linting errors, and :ALENext works great for this operation. By default, ALE maps no bindings, I assume to allow for non-clashing customization.
In your ~/.vimrc (or ~/.config/nvim/init.vim for NeoVim), I use:
nmap <silent> <leader>aj :ALENext<cr>
nmap <silent> <leader>ak :ALEPrevious<cr>
Leader is \ by default
-error, -warning and -info enable jumping to errors, warnings or infos respectively, ignoring anything else. They are mutually exclusive and if several are provided the priority is the following: error > warning > info."
You can easily move between errors by adding some key bindings to ale's <Plug> mappings (see :h <Plug>).
In this example use Ctrl+j to go to next error and Ctrl+k to go to the previous error.
nmap <silent> <C-k> <Plug>(ale_previous_wrap)
nmap <silent> <C-j> <Plug>(ale_next_wrap)
