## Performance compared to other plugins
Unlike other statusline plugins lualine loads only defined components, nothing else.
Startup time performance measured with an amazing plugin [tweekmonster/startuptime.vim](https://github.com/tweekmonster/startuptime.vim)

## Installation
### [vim-plug](https://github.com/junegunn/vim-plug)
```vim
Plug 'hoob3rt/lualine.nvim'
" If you want to have icons in your statusline choose one of these
Plug 'kyazdani42/nvim-web-devicons'
Plug 'ryanoasis/vim-devicons'
```
### [packer.nvim](https://github.com/wbthomason/packer.nvim)
```lua
use {
'hoob3rt/lualine.nvim',
requires = {'kyazdani42/nvim-web-devicons', opt = true}
}
```
## Usage and customization
Lualine has sections as shown below.
```
+-------------------------------------------------+
| A | B | C X | Y | Z |
+-------------------------------------------------+
```
Each sections holds it's components e.g. current vim's mode.
Colorscheme of sections is mirrored, meaning section `A` will have the same colorscheme as section `Z` etc.

Configuration is currently limited to lua, please use lua block or a separate lua file to configure lualine.

### Starting lualine
```lua
local lualine = require('lualine')
lualine.status()
```
### Setting a theme
```lua
lualine.theme = 'gruvbox'
```
<details>
<summary><b>Available themes</b></summary>
* gruvbox
Please create a pr if you managed to port a popular theme before me
</details>
### Changing separator in section
Lualine defines a separator between components in given section, the default
separator is `|`. You can change the separator this way:
```lua
lualine.separator = '|'
```
or disable it
```lua
lualine.separator = ''
```
### Changing components in lualine sections
<details>
<summary><b>Lualine defaults</b></summary>
```lua
lualine.sections = {
lualine_a = { 'mode' },
lualine_b = { 'branch' },
lualine_c = { 'filename' },
lualine_x = { 'encoding', 'fileformat', 'filetype' },
lualine_y = { 'progress' },
lualine_z = { 'location' },
lualine_diagnostics = { }
}
lualine.inactiveSections = {
lualine_a = { },
lualine_b = { },
lualine_c = { 'filename' },
lualine_x = { 'location' },
lualine_y = { },
lualine_z = { }
}
```
</details>
<details>
<summary><b>Available components</b></summary>
* branch
* encoding
* fileformat
* filename
* filetype
* location
* mode
* progress
</details>
<details>
<summary><b>Using custom functions as lualine component</b></summary>
You can define a custom function as a lualine component
```lua
local function hello()
return [[hello world]]
end
lualine.sections = { lualine_a = { hello } }
```
</details>
### Loading plugin extensions
Lualine extensions change statusline appearance for a window/buffer with a plugin loaded e.g. [junegunn/fzf.vim](https://github.com/junegunn/fzf.vim)
By default no plugin extension are loaded to improve performance. If you are using a plugin which is supported you can load it this way:
```lua
lualine.extensions = { 'fzf' }
```
<details>
<summary><b>Available extensions</b></summary>
* fzf
Please create a pr if you managed to create an extension before me
</details>

### Defining custom themes
<details>
<summary><b>Theme example</b></summary>
To create a custom theme you need to define a colorscheme for each of vim's modes. Each mode has a `fg` and `bg` field for every lualine section.
This is really easy in lua. Here is and example of a gruvbox theme.
```lua
local gruvbox = { }
local colors = {
black = "#282828",
white = '#ebdbb2',
red = '#fb4934',
green = '#b8bb26',
blue = '#83a598',
yellow = '#fe8019',
gray = '#a89984',
darkgray = '#3c3836',
lightgray = '#504945',
inactivegray = '#7c6f64',
}
gruvbox.normal = {
a = {
bg = colors.gray,
fg = colors.black,
},
b = {
bg = colors.lightgray,
fg = colors.white,
},
c = {
bg = colors.darkgray,
fg = colors.gray
}
}
gruvbox.insert = {
a = {
bg = colors.blue,
fg = colors.black,
},
b = {
bg = colors.lightgray,
fg = colors.white,
},
c = {
bg = colors.lightgray,
fg = colors.white
}
}
gruvbox.visual = {
a = {
bg = colors.yellow,
fg = colors.black,
},
b = {
bg = colors.lightgray,
fg = colors.white,
},
c = {
bg = colors.inactivegray,
fg = colors.black
},
}
gruvbox.replace = {
a = {
bg = colors.red,
fg = colors.black,
},
b = {
bg = colors.lightgray,
fg = colors.white,
},
c = {
bg = colors.black,
fg = colors.white
},
}
gruvbox.command = {
a = {
bg = colors.green,
fg = colors.black,
},
b = {
bg = colors.lightgray,
fg = colors.white,
},
c = {
bg = colors.inactivegray,
fg = colors.black
},
}
gruvbox.terminal = gruvbox.normal
gruvbox.inactive = {
a = {
bg = colors.darkgray,
fg = colors.gray,
},
b = {
bg = colors.darkgray,
fg = colors.gray,
},
c = {
bg = colors.darkgray,
fg = colors.gray
},
}
lualine.theme = gruvbox
```
