If you do not change the default setting, there is no need to call setup. See ccc-option in doc for the options that can be used. You can see the default options here.

-- Enable true color
vim.opt.termguicolors = true

local ccc = require("ccc")
local mapping = ccc.mapping
ccc.setup({
    -- Your favorite settings
})

This plugin provides five commands and one mapping.

• :CccPick

  • Detects and replaces the color under the cursor.
  • Detectable formats are defined in ccc-option-pickers (See doc).
  • If nothing is detected, the color is inserted at a cursor position.

• <Plug>(ccc-insert)

  • Defined in insert mode.
  • Insert the color without detection.

• :CccConvert

  • Convert color formats directly without opening the UI.
  • The conversion rules are defined in ccc-option-convert.

• :CccHighlighterToggle

• :CccHighlighterEnable

• :CccHighlighterDisable

  • Highlight colors in the buffer.
  • The colors to be highlighted are those returned by textDocument/documentColor request or those registered in ccc-option-pickers.
  • Highlight is managed on a buffer-by-buffer basis, so you must use this command each time to enable highlight on a new buffer.
  • You can use ccc-option-highlighter-auto-enable to enable automatically on BufEnter.
  • The following options are available.
    • ccc-option-highlighter-auto-enable
    • ccc-option-highlighter-filetypes
    • ccc-option-highlighter-excludes
    • ccc-option-highlighter-lsp

All actions have been implemented as lua functions. To customize, use ccc-option-mappings.
