[ofirgall]

Draw boxes with venn.nvim.

local hint = [[
^^^^    Draw
^^^^-------------
Arrows: _<C-h>_ _<C-j>_ _<C-k>_ _<C-l>_
Box (select box with visual block first): _<C-f>_
^ ^				_<Esc>_: exit
]]

Hydra({
	name = 'Draw',
	hint = hint,
	config = {
		color = 'pink',
		invoke_on_body = true,
		hint = {
			position = 'bottom',
			border = 'rounded'
		},
		on_enter = function()
			vim.opt_local.virtualedit = 'all'
		end,
		on_exit = function()
			vim.opt_local.virtualedit = ''
		end
	},
	mode = {'n'},
	body = '<leader>draw',
	heads = {
		{ '<C-h>', '<C-v>h:VBox<CR>' },
		{ '<C-j>', '<C-v>j:VBox<CR>' },
		{ '<C-k>', '<C-v>k:VBox<CR>' },
		{ '<C-l>', '<C-v>l:VBox<CR>' },
		{ '<C-f>', ':VBox<CR>', { mode = 'v' }},
		{ '<Esc>', nil, { exit = true, nowait = true } },
	}
})

You don't need to restore option in on_exit function.

local hint = [[
 Arrow^^^^^^   Select region with <C-v> 
 ^ ^ _K_ ^ ^   _f_: surround it with box
 _H_ ^ ^ _L_
 ^ ^ _J_ ^ ^                      _<Esc>_
]]

Hydra({
   name = 'Draw Diagram',
   hint = hint,
   config = {
      color = 'pink',
      invoke_on_body = true,
      hint = {
         position = 'bottom',
         border = 'rounded'
      },
      on_enter = function()
         vim.o.virtualedit = 'all'
      end,
   },
   mode = 'n',
   body = '<leader>d',
   heads = {
      { 'H', '<C-v>h:VBox<CR>' },
      { 'J', '<C-v>j:VBox<CR>' },
      { 'K', '<C-v>k:VBox<CR>' },
      { 'L', '<C-v>l:VBox<CR>' },
      { 'f', ':VBox<CR>', { mode = 'v' }},
      { '<Esc>', nil, { exit = true } },
   }
})
