Live Preview of mini.base16

[mhanberg]

I am interested in creating a base16 colorscheme that use's my works branding colors as the base. It would be really nice if there was a way to live update a buffer with the changed theme without having to quit and reopen nvim.

Has anyone accomplished this before?

It's a bit complex, but take a look at the new dev mode in 'folke/tokyonightnvim. It would need adjustments, though, depending on how you organize color scheme files.

Also it utilizes 'mini.hipatterns' from 'mini.nvim', so you should be half way there :)

Roger, I think I figured something out.

I have a couple autocmds in a lazy plugin (random spot that would get run on bootup) and then another file that has the palette motchvim.simple.colors.

We reset the colors module when we reload and simply setup the base16 theme again.

Thanks for the tip!

local function reload()
	package.loaded["motchvim.simple.colors"] = nil
	require("mini.base16").setup({
		palette = require("motchvim.simple.colors"),
		use_cterm = true,
	})
end
reload = vim.schedule_wrap(reload)

local augroup = vim.api.nvim_create_augroup("colorscheme_dev", { clear = true })
vim.api.nvim_create_autocmd("User", {
	pattern = "VeryLazy",
	group = augroup,
	callback = reload,
})
vim.api.nvim_create_autocmd("BufWritePost", {
	group = augroup,
	pattern = "*simple/colors.lua",
	callback = reload,
})

return {}
