# About

<div style="text-align: justify">
	Catppuccino.nvim is a NeoVim plugin that provides multiple colorschemes based on the Catppuccino color palette but varying their properties. Apart from the eye-candy colorschemes, Catppuccino.nvim also provides integrations with multiple plugins and tools you are probably already using (e.g. Treesitter, Native LSP, ...).

# 📦 Installation

## Prerequisites

-   [NeoVim 0.5+](https://github.com/neovim/neovim/releases/tag/v0.5.0)

## Adding the plugin

You can use your favorite plugin manager for this. Here are some examples with the most popular ones:

### Vim-plug

```lua
Plug 'Pocco81/Catppuccino.nvim'
```

### Packer.nvim

```lua
use "Pocco81/Catppuccino.nvim"
```

### Vundle

```lua
Plugin 'Pocco81/Catppuccino.nvim'
```

### NeoBundle

```lua
NeoBundleFetch 'Pocco81/Catppuccino.nvim'
```

## Setup

There are already some sane defaults that you may like, however you can change them to match your taste. These are the defaults:

```lua
colorscheme = "dark_catppuccino",
transparency = false,
term_colors = false,
styles = {
	comments = "italic",
	functions = "italic",
	keywords = "italic",
	strings = "NONE",
	variables = "NONE",
},
integrations = {
	treesitter = true,
	native_lsp = {
		enabled = true,
		virtual_text = {
			errors = "italic",
			hints = "italic",
			warnings = "italic",
			information = "italic",
		},
		underlines = {
			errors = "underline",
			hints = "underline",
			warnings = "underline",
			information = "underline",
		}
	},
	lsp_trouble = false,
	lsp_saga = false,
	gitgutter = false,
	gitsigns = false,
	telescope = false,
	nvimtree = {
		enabled = false,
		show_root = false,
	},
	which_key = false,
	indent_blankline = {
		enabled = false,
		colored_indent_levels = false,
	},
	dashboard = false,
	neogit = false,
	vim_sneak = false,
	fern = false,
	barbar = false,
	bufferline = false,
	markdown = false,
	lightspeed = false,
	ts_rainbow = false,
	hop = false,
}
```

The way you setup the settings on your configuration varies on whether you are using vimL for this or Lua.

After setting things up, you can load Catppuccino like so:

```vim
" Vim Script
colorscheme catppuccino
```

```lua
-- Lua
vim.cmd[[colorscheme catppuccino]]
```
Passing `catppuccino` to the `colorscheme` command will pick the colorscheme in the config. Optionally, you could pass one by its code name (e.g. `colorscheme neon_latte`).

For instructions on how to configure the plugin, check out the [configuration](#configuration) section.

## Updating

This depends on your plugin manager. If, for example, you are using Packer.nvim, you can update it with this command:

```lua
:PackerUpdate
```

# 🤖 Usage

## Commands

The provides commands that follows the _camel casing_ naming convention and have the `CP` prefix so that it's easy to remember that they are part of Catppuccino.nvim:

-   `:CPClear` clear all highlight groups.
-   `:colorscheme <colorscheme_name>` load a colorscheme, not necessarily a Catppuccino one. (Note: this is a built-in NVim command).

## API

The API allows you fetch data from Catppuccino. It can be required as a Lua module:

```lua
local cp_api = require("catppuccino.api.<module>")
```

### Modules

-   `colors`

```lua
cp_api.get_colors(<colorscheme>)
```

> Gets the colors from `<colorscheme>`. Returns two values: the first one is a table with a `status` field (for the exit status) and a `msg` field with an error message in case `status` is `false` (error), and the second value is a table with the colors. If it fails, it will return the colors from `dark_catppuccino`.

# 🐬 Configuration

Although settings already have self-explanatory names, here is where you can find info about each one of them and their classifications!

## General

This settings are unrelated to any group and are independent.

-   `colorscheme`: (String) code name of the color-scheme to be used. All of them can be found in the section below.
-   `transparency`: (Boolean) if true, disables setting the background color.
-   `term_colors`: (Boolean) if true, sets terminal colors (e.g. `g:terminal_color_0`).

## Styles

Handles the style of general hi groups (see `:h highlight-args`):

-   `comments`: (String) changed the style of the comments.
-   `functions`: (String) changed the style of the functions.
-   `keywords`: (String) changed the style of the keywords.
-   `strings`: (String) changed the style of the strings.
-   `variables`: (String) changed the style of the variables.

## Integrations

These integrations allow Catppuccino to set the theme of various plugins/stuff. To enable an integration you just need to set it to `true`, however, there are some special integrations...

If you'd like to know which highlight groups are being affected by Catppuccino, checkout this directory: [`lua/catppuccino/core/integrations/`](https://github.com/Pocco81/Catppuccino.nvim/tree/main/lua/catppuccino/core/integrations).

### Special Integrations

-   **Native Nvim LSP:** setting `enabled` to `true` enables this integration. In the inners tables you can set the style for the diagnostics, both `virtual_text` (what you see on the side) and `underlines` (what points directly at the thing (e.g. an error)).
-   **Lualine:** use this to set it up (Note: `catppuccino` is the only valid theme name. It will pick the one set in your config):

```lua
require('lualine').setup {
  options = {
    theme = "catppuccino"
	-- ... the rest of your lualine config
  }
}
```

-   **Lightline:** use this to set it up (Note: `catppuccino` is the only valid colorscheme name. It will pick the one set in your config):

```lua
let g:lightline = {'colorscheme': 'catppuccino'}
```

-   **Kitty:** Copy and paste the file corresponding to theme you want to use from [this directory](https://github.com/Pocco81/Catppuccino.nvim/tree/main/extra/kitty) on your Kitty config.
-   **Alacritty:** Copy and paste the file corresponding to theme you want to use from [this directory](https://github.com/Pocco81/Catppuccino.nvim/tree/main/extra/alacritty) on your Alacritty config.
-   **Tmux**: Follow the instructions [here](https://github.com/Pocco81/Catppuccino.nvim/tree/main/extra/tmux)
-   **Indent-blankline.nvim**: setting `enabled` to `true` enables this integration. `colored_indent_levels` enables char highlights per indent level. Follow the instructions [here](https://github.com/lukas-reineke/indent-blankline.nvim#with-custom-gindent_blankline_char_highlight_list) to set the latter up.
-   **NvimTree:** setting `enabled` to `true` enables this integration:

```lua
integration = {
  nvimtree = {
    enabled = true,
    show_root = true, -- makes the root folder not transparent
  }
}
```

## List of colorschemes

| Colorschemes     | Code Names         |
| ---------------- | ------------------ |
| Dark Catppuccino | `dark_catppuccino` |
| Neon Latte       | `neon_latte`       |
| Soft Manilo      | `soft_manilo`      |
| Light Melya      | `light_melya`      |

## Overwriting colors & hi groups

Both colors and highlight groups can be overwritten like so:

```lua
catppuccino.remap({<colors>},{<hi_groups>})
```

Since you want to overwrite hi groups, then it's likely that you'll want to use the API to get the colors from x colorscheme as well:

```lua
local err, colors = cp_api.get_colors("neon_latte")
```

Here is an example using the API to overwrite the color green and change the style of the comments:

```lua
local cp_api = require("catppuccino.api.colors")
local err, colors = cp_api.get_colors("neon_latte")

if err.status then -- good
	catppuccino.remap({
		green = "#ffffff"
	},
	{
		Comment = { fg = colors.comment, style = "bold" }, -- any comment
	})
end
```

-   For colorschemes: all editable fields are the same as the ones mentioned in any of the colorschemes found at: [`lua/catppuccino/color_schemes`](https://github.com/Pocco81/Catppuccino.nvim/tree/main/lua/catppuccino/color_schemes). You could also use one as a template, if you will.
-   For highlight groups: all the highlight groups have three editable fields: `fg` for the foreground, `bg` for the background and `style` for the style.

## Hooks

Use them to execute code at certain events [described by their names]. These are the ones available:

| Function           | Description                  |
| ------------------ | ---------------------------- |
| `before_loading()` | Before loading a colorscheme |
| `after_loading()`  | After loading a colorscheme  |

They can be used like so:

```lua
local catppuccino = require("catppuccino")

catppuccino.before_loading = function ()
	print("I ran before setting a colorscheme!")
end
```

# 🙋 FAQ

-   Q: **_"How can I view the doc from NeoVim?"_**
    A: Use `:help Catppuccino.nvim`

-   Q: **_"Why are the colorschemes named like that? Do they follow any convention(s)?"_**
    A: A colorscheme's name is constructed by two words: the first one is a word that represents the tonalities in the colors used and the second one is the name of a coffee drink from [this list](https://en.wikipedia.org/wiki/List_of_coffee_drinks).
