INTRODUCTION					*lightline-introduction*

The *lightline* plugin is a light and configurable statusline for Vim.

------------------------------------------------------------------------------
OPTIONS						*lightline-options*

	g:lightline				*g:lightline*
		All the options are stored into this global variable.

	g:lightline.active			*g:lightline.active*
	g:lightline.inactive			*g:lightline.inactive*
		Dictionaries to specify the status components.
		The default values are:
>
		let g:lightline.active = {
		    \ 'left': [ [ 'mode', 'paste' ],
		    \           [ 'fugitive', 'readonly', 'filename', 'modified' ] ],
		    \ 'right': [ [ 'lineinfo' ],
		    \            [ 'percent' ],
		    \            [ 'fileformat', 'fileencoding', 'filetype' ] ] }
		let g:lightline.inactive = {
		    \ 'left': [ [ 'filename' ] ],
		    \ 'right': [ [ 'lineinfo' ],
		    \            [ 'percent' ] ] }
<
	g:lightline.component			*g:lightline.component*
		Dictionary for statusline components.
		The default value is:
>
		let g:lightline.component = {
		    \ 'mode': '%{lightline#mode()}',
		    \ 'filename': '%t',
		    \ 'modified': '%M',
		    \ 'paste': '%{&paste?"PASTE":""}',
		    \ 'readonly': '%R',
		    \ 'fileencoding': '%{strlen(&fenc)?&fenc:&enc}',
		    \ 'fileformat': '%{&fileformat}',
		    \ 'filetype': '%{strlen(&filetype)?&filetype:"no ft"}',
		    \ 'percent': '%3p%%',
		    \ 'lineinfo': '%3l:%-2v',
		    \ 'fugitive': '%{exists("*fugitive#head")?fugitive#head():""}' }
<
	g:lightline.component_flag			*g:lightline.component_flag*
		Dictionary of boolean expressions for the components.
		Each expression corresponds to if the component have non-zero
		length.
		For example, the flag for paste component is:
>
		let g:lightline.component_flag = {
		    \ 'paste': '(&paste)' }
<
		Users are recommended to set this option together with the
		component itself.

	g:lightline.component_func			*g:lightline.component_func*
		Another dictionary for components. This is more convenient
		because the user does not have to set both component and
		component_flag.
		For example, if you want a component for readonly mark, which
		disappears in help windows:
>
		let g:lightline = {
			\ 'active': {
			\   'left': [ [ 'mode', 'paste' ],
			\             [ 'myreadonly', 'filename', 'modified' ] ],
			\ },
			\ 'component_func': {
			\   'myreadonly': 'MyReadonly'
			\ },
			\ }
		function! MyReadonly()
			return &ft !~? 'help' && &ro ? 'RO' : ''
		endfunction
<
	g:lightline.colorscheme			*g:lightline.colorscheme*
		The colorscheme for lightline.vim.
		Currently, wombat, solarized and landscape are available.
>
		let g:lightline.colorscheme = 'default'
<
	g:lightline.mode_map			*g:lightline.mode_map*
		A dictionary of names for mode.
		The default value is:
>
		let g:lightline.mode_map = {
		    \ 'n' : 'NORMAL',
		    \ 'i' : 'INSERT',
		    \ 'R' : 'REPLACE',
		    \ 'v' : 'VISUAL',
		    \ 'V' : 'V-LINE',
		    \ 'c' : 'COMMAND',
		    \ '': 'V-BLOCK',
		    \ 's' : 'SELECT',
		    \ 'S' : 'S-LINE',
		    \ '': 'S-BLOCK',
		    \ '?': '      ' }
<

------------------------------------------------------------------------------
EXAMPLES					*lightline-examples*
You can configure the appearance of statusline.
Write the following examples in you .vimrc(_vimrc).

In order to change the colorscheme:
>
	let g:lightline = {
		\ 'colorscheme': 'wombat',
		\ }

In order to define own component:
>
	let g:lightline = {
		\ 'active': {
		\   'left': [ [ 'mode', 'paste' ], [ 'myfilename' ] ]
		\ },
		\ 'component_func': {
		\   'myfilename': 'MyFilename',
		\   'myreadonly': 'MyReadonly',
		\   'mymodified': 'MyModified',
		\ },
		\ }
	function! MyFilename()
		return ('' != MyReadonly() ? MyReadonly() . ' ' : '') .
		      \ (&ft == 'vimfiler' ? vimfiler#get_status_string() : 
		      \  &ft == 'unite' ? unite#get_status_string() : 
		      \ '' != expand('%t') ? expand('%t') : '[No Name]') .
		      \ ('' != MyModified() ? ' ' . MyModified() : '')
	endfunction
	function! MyReadonly()
		return &ft !~? 'help' && &ro ? 'RO' : ''
	endfunction
	function! MyModified()
		return &modifiable && &modified ? '+' : ''
	endfunction

Separators settings:
>
	let g:lightline = {
		\ 'separator': { 'left': '▶', 'right': '◀' },
		\ 'subseparator': { 'left': '>', 'right': '<' }
		\ }
<

For |powerline| font users:
>
	let g:lightline = {
		\ 'separator': { 'left': '', 'right': '' },
		\ 'subseparator': { 'left': '', 'right': '' }
		\ }
<

For |vim-powerline| font users:
>
	let g:lightline = {
		\ 'separator': { 'left': '⮀', 'right': '⮂' },
		\ 'subseparator': { 'left': '⮁', 'right': '⮃' }
		\ }
<
