## How Can I Set The Font/Scale The UI Size?
|
||
|
|
|
||
|
|
This is handled through the `guifont` option, settable through Neovim. It's technically documented
|
||
|
|
in `:h guifont` (type this in Neovim), though some things are misleading there, so here we do what's
|
||
|
|
discouraged and try to document it ourselves:
|
||
|
|
|
||
|
|
- The basic format is `IBM_Plex_Mono,Hack,Noto_Color_Emoji:option1:option2`. You can use arbitrarily
|
||
|
|
many "font fallbacks" (`Hack` and `Noto_Color_Emoji` "help out" if `IBM_Plex_Mono` doesn't define
|
||
|
|
a character), and arbitrarily many options. Though please note that _first_ all fonts are defined,
|
||
|
|
_then_ all options, the options apply "globally".
|
||
|
|
- Use `:set guifont=*` to open up a window showing what fonts are accessible by Neovide, hit `Enter`
|
||
|
|
on one to apply it **temporarily**.
|
||
|
|
- Spaces in the font name are a bit difficult to write, either use underscores (`_`) or escape them
|
||
|
|
(`\`).
|
||
|
|
- The font options Neovide supports at the moment are:
|
||
|
|
- `hXX` — Set the font size to `XX`, can be any (even non-two-digit) number or even a floating
|
||
|
|
point number.
|
||
|
|
- `b` — Sets the font **bold**.
|
||
|
|
- `i` — Sets the font _italic_.
|
||
|
|
|
||
|
|
By the way, the default font used is Fira Code at size 14.
|
||
|
|
|
||
|
|
## How Can I Dynamically Change The Font Size At Runtime?
|
||
|
|
|
||
|
|
Not directly in Neovide, but configurable if you want so. A way to accomplish that in Lua would be:
|
||
|
|
|
||
|
|
```lua
|
||
|
|
vim.g.gui_font_default_size = 12
|
||
|
|
vim.g.gui_font_size = vim.g.gui_font_default_size
|
||
|
|
vim.g.gui_font_face = "Fira Code Retina"
|
||
|
|
|
||
|
|
RefreshGuiFont = function()
|
||
|
|
vim.opt.guifont = string.format("%s:h%s",vim.g.gui_font_face, vim.g.gui_font_size)
|
||
|
|
end
|
||
|
|
|
||
|
|
ResizeGuiFont = function(delta)
|
||
|
|
vim.g.gui_font_size = vim.g.gui_font_size + delta
|
||
|
|
RefreshGuiFont()
|
||
|
|
end
|
||
|
|
|
||
|
|
ResetGuiFont = function()
|
||
|
|
vim.g.gui_font_size = vim.g.gui_font_default_size
|
||
|
|
RefreshGuiFont()
|
||
|
|
end
|
||
|
|
|
||
|
|
-- Call function on startup to set default value
|
||
|
|
ResetGuiFont()
|
||
|
|
|
||
|
|
-- Keymaps
|
||
|
|
|
||
|
|
local opts = { noremap = true, silent = true }
|
||
|
|
|
||
|
|
vim.keymap.set({'n', 'i'}, "<C-+>", function() ResizeGuiFont(1) end, opts)
|
||
|
|
vim.keymap.set({'n', 'i'}, "<C-->", function() ResizeGuiFont(-1) end, opts)
|
||
|
|
```
