Using FzfLua.lgrep_curbuf() when viewing man pages with "nvim +Man!"

[paulhdk]

I'm using Neovim as my manpager with "nvim +Man!".

My FzfLua.lgrep_curbuf mapping doesn't work:

[Fzf-lua] Rg current buffer requires file on disk

The buftype of the man pages appears to be nofile, which probably causes the error.

I tried using FzfLua.blines as a workaround, which works, but it's not the same.

Does anyone know of a neat workaround here?

lgrep_curbuf uses rg (ripgrep) under the hood, so it literally needs a file path to read from disk. Man pages are virtual buffers (buftype=nofile) with no backing file — hence the error.

Your options:

1. blines — reads buffer contents directly (no disk file needed). Add search pattern:

   FzfLua.blines({ fzf_opts = { ["--query"] = "your_search" } })

2. Conditional mapping — use blines for nofile buffers:

   vim.keymap.set("n", "<leader>gm", function()
     if vim.bo.buftype == "nofile" then
       FzfLua.blines()
     else
       FzfLua.lgrep_curbuf()
     end
   end)

blines is your best bet here — designed to work with any buffer contents regardless of backing file.

lgrep_curbuf, similar to live_grep/grep uses rg in the background which requires the buffer to have a file system presence - that’s not possible with man pages as the Man contents is a buffer which isn’t saved to disk.

Use blines instead.

Ty @anntnzrb, your answer is more detailed than mine :)
