Integrations

Integrations

Neotheme includes opt-in highlight definitions for 15 plugin surfaces. Every integration defaults to false.

Enable integrations

require("neotheme").setup({
	integrations = {
		bufferline = true,
		gitsigns = true,
		nvim_tree = true,
		telescope = true,
		which_key = true,
	},
})

vim.cmd.colorscheme("neotheme")

Integration loading behavior

Enabling an integration tells Neotheme to define that plugin's highlight groups when the colorscheme loads. Neotheme does not require or load the plugin module itself.

This means:

• Plugin load order does not need to match integration module load order.
• Enabling an integration for an absent plugin only creates unused highlight groups.
• Disabled integrations do not define their plugin-specific groups.
• Palette customization reaches enabled integrations because their definitions consume the resolved semantic palette.

Apply changes after startup

After changing integration options, reload the colorscheme:

require("neotheme").setup({
	integrations = {
		nvim_tree = true,
	},
})

vim.cmd.colorscheme("neotheme")

Calling setup alone updates resolved state but does not recreate active highlight groups.

Lualine is separate

Lualine discovers Neotheme through its theme loader and does not use an integrations.lualine option. Configure it with theme = "neotheme" inside Lualine. See Lualine.

Integration troubleshooting

If a plugin still uses its default colors:

1. Confirm its exact setup key is true.
2. Confirm vim.cmd.colorscheme("neotheme") runs after setup.
3. Check whether the plugin overrides highlights after the ColorScheme event.
4. Reload the colorscheme after changing integration options.

See Troubleshooting for more diagnostic steps.
