pretty-fold

This goes in: /.config/nvim/lua/user/plugins.lua (to install pretty-fold , look at lower line )

-- Install your plugins here
return packer.startup(function(use)
  -- My plugins here
  use 'wbthomason/packer.nvim' -- Have packer manage itself
  use "nvim-lua/plenary.nvim" -- Useful lua functions used ny lots of plugins

  -- Automatically set up your configuration after cloning packer.nvim
  -- Put this at the end after all plugins
  if PACKER_BOOTSTRAP then
    require('packer').sync()
  end


    use { 'anuvyklack/pretty-fold.nvim',
       config = function()
          require('pretty-fold').setup()
       end
    }

    use { 'anuvyklack/fold-preview.nvim',
       requires = 'anuvyklack/keymap-amend.nvim',
       config = function()
          require('fold-preview').setup({
         -- Your configuration goes here.
         --
          })
       end
    }


end)

config for pretty-fold , need to have both in order to work

and then in init.vim set this

set foldmethod=indent

nnoremap zf <cmd>setl fdm&<CR>zf
xnoremap zf <cmd>setl fdm&<CR>zf

lua require("user.plugins")


set foldcolumn=1



highlight FoldColumn ctermbg=235 guibg=#262626

highlight FoldColumn ctermfg=white guifg=white

This is how it looks. Really neat :D

So this means:

za : open/close the fold under the cursor

zR : open all folds in the file

zM : close all folds in the file

zf<motion> - define your own manual fold, defined by <motion>

when you step the cursor on fold line (block..)

h - to show a preview

l - to open fold (same as za , but more intuitive)
