Default Options

require("synthwave-85.nvim").setup({
  transparent = false,      -- Enable transparent background
  terminal_colors = true,   -- Set terminal colors (0-15)
  italics = {
    comments = true,        -- Italic comments

  transparent = true,
})

Italics

You can control italics globally or for specific syntax categories:

-- Disable all italics
require("synthwave-85.nvim").setup({
  italics = false,
})

-- Or fine-tune specific categories
require("synthwave-85.nvim").setup({
  italics = {
    comments = true,
    keywords = true,
    functions = false,
    strings = false,
    variables = false,
    parameters = true,
  },
})

Custom Overrides

Override any highlight group with your own settings:

require("synthwave-85.nvim").setup({
  overrides = {
    -- Make comments bold
    Comment = { bold = true },
    -- Custom cursor line
    CursorLine = { bg = "#2a2139" },
    -- Override a specific plugin group
    TelescopeSelection = { bg = "#34294f", bold = true },
  },
})
