Why yet another clone of powerline?

• vim-powerline is a nice plugin, but deprecated.
• powerline is a nice plugin, but difficult to configure.
• vim-airline is a nice plugin, but it uses too many functions of other plugins, which should be done by users in .vimrc.

Spirit of this plugin

• Minimalism. The core script is very small to achieve enough functions as a statusline plugin.
• Configurability. You can create your own component and easily add to the statusline and the tabline.
• Orthogonality. The plugin does not rely on the implementation of other plugins. Such plugin crossing settings should be configured by users.

Introduction

After installing this plugin, you restart the editor and will get a cool statusline.

The color of the statusline changes due to the mode of Vim. Try typing something, selecting in visual mode and replacing some texts.

If the statusline looks like

add the following configuration to your .vimrc.

set laststatus=2

If the statusline is not coloured like

then modify TERM in your shell configuration (.zshrc for example)

export TERM=xterm-256color

and then add the following configuration to your .vimrc.

if !has('gui_running')
  set t_Co=256
endif

Your statusline appears to work correctly? If yes, great, thanks for choosing lightline.vim! If no, please file an issue report to the issue tracker.

By the way, -- INSERT -- is unnecessary anymore because the mode information is displayed in the statusline. If you want to get rid of it, configure as follows.

set noshowmode

Colorscheme configuration

The lightline.vim plugin provides multiple colorschemes to meet your editor colorscheme. Do not be confused, editor colorscheme rules how codes look like in buffers and lightline.vim has independent colorscheme feature, which rules how the statusline looks like.

If you are using wombat colorscheme, add the following setting to your .vimrc,

let g:lightline = {
      \ 'colorscheme': 'wombat',
      \ }

restart Vim and the statusline looks like:

If the colors of the statusline do not change, move the settings of g:lightline before setting the editor colorscheme.

There are many lightline colorschemes available as screenshots shown above. See :h g:lightline.colorscheme for the complete list.

Advanced configuration

The default appearance of lightline.vim is carefully designed that the tutorial is enough here for most people. So please read this section if you really want to configure and enjoy the configurability of lightline.vim.

Sometimes people want to display information of other plugins. For example git branch information, syntax check errors and some statuses of plugins.

The lightline.vim plugin does not provide any plugin integration by default. This plugin considers orthogonality to be one of the important ideas, which means that the plugin does not rely on implementation of other plugins. Once a plugin starts to integrate with some famous plugins, it should be kept updated to follow the changes of the plugins, and should accept integration requests with new plugins and it will suffer from performance regression due to plugin availability checks.

Instead, lightline.vim provides a simple API that user can easily integrate with other plugins. Once you understand how to configure and how it will be displayed in the statusline, you can also tell how to integrate with your favorite plugins.

Let's start to configure the appearance. The statusline is composed of multiple components. It shows the current mode, filename, modified status on the left, and file format, encoding, filetype and cursor positions on the right. So in order to add something in the statusline, you firstly create a new component and specify the place.

This is the hello world of lightline.vim component.

let g:lightline = {
      \ 'colorscheme': 'wombat',
      \ 'active': {
      \   'left': [ [ 'mode', 'paste' ],
      \             [ 'readonly', 'filename', 'modified', 'helloworld' ] ]
      \ },
      \ 'component': {
      \   'helloworld': 'Hello, world!'
      \ },
      \ }

The statusline will look like:

You have succeeded in displaying Hello, world! in the statusline. The helloworld component is added to g:lightline.active.left and its content is configured in g:lightline.component. The component contents are simply added to &statusline. Try :echo &statusline, it might be a little bit complicated, but you will find Hello, world! somewhere.

You can use 'statusline' syntax for lightline.vim components. Consult :h 'statusline' to see what's available here. For example, if you want to print the value of character under the cursor in hexadecimal, configure as

let g:lightline = {
      \ 'colorscheme': 'wombat',
      \ 'active': {
      \   'left': [ [ 'mode', 'paste' ],
      \             [ 'readonly', 'filename', 'modified', 'charvaluehex' ] ]
      \ },
      \ 'component': {
      \   'charvaluehex': '0x%B'
      \ },
      \ }

You want the character value information on the right hand side? OK, configure as

let g:lightline = {
      \ 'colorscheme': 'wombat',
      \ 'active': {
      \   'right': [ [ 'lineinfo' ],
      \              [ 'percent' ],
      \              [ 'fileformat', 'fileencoding', 'filetype', 'charvaluehex' ] ]
      \ },
      \ 'component': {
      \   'charvaluehex': '0x%B'
      \ },
      \ }

We have learned how to add a simple component.

• See :h 'statusline' to check the statusline flags.
• Add a new component to g:lightline.component.
• Add the component name to g:lightline.active.left or g:lightline.active.right.

You can also configure the statusline of inactive buffers by adding the component to g:lightline.inactive.left or g:lightline.inactive.right.

Now let's add some integrations with other plugin. The name of the git branch is important these days. But lightline.vim does not provide this information by default because it is also one of plugin crossing configurations, and not all people want the integration.

In order to show the branch name in the statusline, install some plugins which provide the branch information. The vim-fugitive plugin is a famous plugin so let's integrate lig
