How to change Neovim font?

Question

VIM contains a 'set guifont' option to change the font. Neovim does not support this option, so I am wondering if it's possible to change the font Neovim uses in the Terminal?

Answer 1

Just change the font in your terminal emulator's preferences. Terminal vim behaves the same way. Only GUI clients like Gvim or macvim use the set guifont option.

Answer 2

This is not for a terminal, but still it might be useful to someone.

For Neovim-Qt GUI client, you can change the font by Ctrl + mouse scroll if you put the following to ginit.vim:

let s:fontsize = 12
function! AdjustFontSize(amount)
  let s:fontsize = s:fontsize+a:amount
  :execute "GuiFont! Consolas:h" . s:fontsize
endfunction

noremap <C-ScrollWheelUp> :call AdjustFontSize(1)<CR>
noremap <C-ScrollWheelDown> :call AdjustFontSize(-1)<CR>
inoremap <C-ScrollWheelUp> <Esc>:call AdjustFontSize(1)<CR>a
inoremap <C-ScrollWheelDown> <Esc>:call AdjustFontSize(-1)<CR>a

For those who prefer using keyboard, there is a nice way to use numpad's + (kPlus) and - (kMinus)

" In normal mode, pressing numpad's+ increases the font
noremap <kPlus> :call AdjustFontSize(1)<CR>
noremap <kMinus> :call AdjustFontSize(-1)<CR>

" In insert mode, pressing ctrl + numpad's+ increases the font
inoremap <C-kPlus> <Esc>:call AdjustFontSize(1)<CR>a
inoremap <C-kMinus> <Esc>:call AdjustFontSize(-1)<CR>a

Obviously you can replace Consolas with the font you prefer.

Answer 3

I use Neovim-qt version on my Ubuntu18.04. But I use the same config file for my vim.

After trial-and-error, I found the way to change neovim font to FiraCode Monospace. Although you could type the command :Guifont Fira Mono:h12 inside GUI to change the currently used font, it works only once. After you close the GUI, need to set up the font again. : (
Or you need another config file ginit.vim to set up GUI-related things. The same problem of setting up font for GUI, just write GuiFont Fira Mono:h12 in ginit.vim.

Answer 4

Apart from the answers in this question, the reason many scripts/plugins that works for vim/Gvim but not NeoVim (qt) is that in NeoVim, the font is defined by Guifont instead of guifont.
