I am trying to re-indent a foo.html.erb file, however when I do gg=G everything gets aligned to the beginning of the line. I couldn't figure out why that happens. I've tried installing polyglot or putting eruby.vim into ftplugin but none of them worked.

:set filetype? returns filetype=eruby

enter image description here

Here is my .vimrc:

set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')

" let Vundle manage Vundle, required

" All of your Plugins must be added before the following line

" To ignore plugin indent changes, instead use:

In your screenshot, all the lines which end with %> also start with <%=, except this one:

<= render 'shared/footer' %>

If you add a percent character between the leading < and the following =:

<%= render 'shared/footer' %>

Then gg=G indents your file like this:

<!DOCTYPE html>
    <meta name="viewport" content="width=device-width,initial-scale=1">
    <%= csrf_meta_tags %>
    <%= csp_meta_tag %>

    <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
    <%= stylesheet_pack_tag 'application', 'data-turbolinks-track': 'reload' %>

    <%= render 'shared/navbar' %>
    <%= render 'shared/notices' %>

    <div class="container-fluid">
      <%= yield %>

    <%= render 'shared/footer' %>

  • Thank you so much. I was scratching my head over this for quite some time. Sorry for the image, I wanted to show how it looks but next time I will make sure to post the content as well. Mar 7 at 12:29
