Opening neovim docs in the current window instead of a split

[aslamosama]

If I select an option from the helptags it opens in a horizontal split by default. Is there a way to make it open in full screen by default. I found a custom function help-curwin in neovim docs but I have no idea how to use it with fzf.lua helptags.

That behavior is controlled by neovim, run :help and it will be the same behavior, you can open in a vertical split by running :vert help but I’m not sure what/if there’s a command to open directly in full screen mode. You can however create a custom fzf-lua action that opens the help and then executes <C-w><C-o> to make the new buffer the only window.

I found help-curwin in neovim docs. and adding this to my init.lua I was able to use :HelpCurwin to open help in fullscreen.

vim.cmd([[
command -bar -nargs=? -complete=help HelpCurwin call HelpCurwin(<q-args>)

let g:did_open_help = v:false

function! HelpCurwin(subject) abort
  let mods = 'silent noautocmd keepalt'
  if !g:did_open_help
    execute mods .. ' help'
    execute mods .. ' helpclose'
    let g:did_open_help = v:true
  endif
  if !empty(getcompletion(a:subject, 'help'))
    execute mods .. ' edit ' .. &helpfile
    set buftype=help
  endif
  return 'help ' .. a:subject
endfunction
]])

That’s great, you can do the same with fzf-lua by copying the current action (2 lines) and changing the cmd to whatever you wanted and set the new action as your help default action:

fzf-lua/lua/fzf-lua/actions.lua

Lines 569 to 572 in 06d4fe9

	M.help = function(selected)
	local vimcmd = "help"
	M.vimcmd(vimcmd, helptags(selected), true)
	end

Hey @ibhagwan,

would you be interested in a PR implementing this behind an option? I have my own patch that I've been using for a while, so I would just need to wrap it.

(I made a similar proposal for Telescope, but I never got an answer)

Sure why not, but not as a new action users can configure instead of the default, I wouldn’t change the default behavior at this point.
