How to access the current palette of a colorscheme.

[WayneNoschang]

Some Neovim colorscheme plugins provide a way to require and use the currently used theme colors for use with other plugins. For example, a helper in onedarkpro.nvim theme.

Is there an API that I'm overlooking in the docs that allows me to do this?

The closest thing I can find is require("github-theme.palette") mentioned in the Color lib section of the READ.me. However, this will provide all palette styles or a specified one.

I want to be able to create a lualine theme by using the current theme's palette.

Below is an example using olimorris/onedarkpro.nvim to create a new lualine theme located in lua/lualine/theme/theme_name.lua.

-- https://github.com/nvim-lualine/lualine.nvim/wiki/Writing-a-theme
-- https://github.com/olimorris/onedarkpro.nvim/blob/main/lua/lualine/themes/onedark.lua

local colors = require("onedarkpro.helpers").get_colors()

local onedarkpro = {}

onedarkpro.normal = {
  a = { fg = colors.fg },
  b = { fg = colors.fg },
  c = { fg = colors.fg },
  x = { fg = colors.fg },
  y = { fg = colors.fg },
  z = { fg = colors.fg },
}

onedarkpro.insert = {
  a = { fg = colors.fg },
  b = { fg = colors.fg },
  c = { fg = colors.fg },
}

onedarkpro.command = {
  a = { fg = colors.fg },
  b = { fg = colors.fg },
  c = { fg = colors.fg },
}

return onedarkpro

You can try:

require("github-theme.palette").load(vim.g.colors_name)
