INTRODUCTION *lightline-introduction*
|
|
|
|
The *lightline* plugin is a light and configurable statusline/tabline for Vim.
|
|
|
|
------------------------------------------------------------------------------
|
|
SPIRIT *lightline-spirit*
|
|
|
|
Minimalism
|
|
The core script is very small.
|
|
|
|
Configurability
|
|
You can create your own component and easily add to the
|
|
statusline/tabline.
|
|
|
|
Orthogonality
|
|
Any plugin should not change the settings of another plugin.
|
|
Such plugin-crossing settings should be written by users in
|
|
.vimrc.
|
|
|
|
You might find this plugin is not so useful by default. This plugin
|
|
does not provide the branch information, which is a very basic
|
|
component in existing plugins. The reason is that branch component is
|
|
one of plugin-crossing settings so users should write the settings
|
|
using the APIs of the both plugins. Hospitality makes a plugin messy.
|
|
Good APIs keep a plugin clean.
|
|
|
|
------------------------------------------------------------------------------
|
|
OPTIONS *lightline-option*
|
|
|
|
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*
|
|
g:lightline.tabline *g:lightline.tabline*
|
|
Dictionaries to specify the statusline/tabline components.
|
|
The components are gathered from either |g:lightline.component|,
|
|
|g:lightline.component_function| or
|
|
|g:lightline.component_expand|.
|
|
Note that right groups of components are stored from right to
|
|
left. The default values are:
|
|
>
|
|
let g:lightline.active = {
|
|
\ 'left': [ [ 'mode', 'paste' ],
|
|
\ [ 'readonly', 'filename', 'modified' ] ],
|
|
\ 'right': [ [ 'lineinfo' ],
|
|
\ [ 'percent' ],
|
|
\ [ 'fileformat', 'fileencoding', 'filetype' ] ] }
|
|
let g:lightline.inactive = {
|
|
\ 'left': [ [ 'filename' ] ],
|
|
\ 'right': [ [ 'lineinfo' ],
|
|
\ [ 'percent' ] ] }
|
|
let g:lightline.tabline = {
|
|
\ 'left': [ [ 'tabs' ] ],
|
|
\ 'right': [ [ 'close' ] ] }
|
|
<
|
|
g:lightline.tab *g:lightline.tab*
|
|
Dictionaries to specify the components in each tabs.
|
|
The components are gathered from either
|
|
|g:lightline.tab_component| or
|
|
|g:lightline.tab_component_function|.
|
|
The default values are:
|
|
>
|
|
let g:lightline.tab = {
|
|
\ 'active': [ 'tabnum', 'filename', 'modified' ],
|
|
\ 'inactive': [ 'tabnum', 'filename', 'modified' ] }
|
|
<
|
|
g:lightline.component *g:lightline.component*
|
|
Dictionary for statusline/tabline components.
|
|
The default value is:
|
|
>
|
|
let g:lightline.component = {
|
|
\ 'mode': '%{lightline#mode()}',
|
|
\ 'absolutepath': '%F',
|
|
\ 'relativepath': '%f',
|
|
\ 'filename': '%t',
|
|
\ 'modified': '%M',
|
|
\ 'bufnum': '%n',
|
|
\ 'paste': '%{&paste?"PASTE":""}',
|
|
\ 'readonly': '%R',
|
|
\ 'charvalue': '%b',
|
|
\ 'charvaluehex': '%B',
|
|
\ 'fileencoding': '%{&fenc!=#""?&fenc:&enc}',
|
|
\ 'fileformat': '%{&ff}',
|
|
\ 'filetype': '%{&ft!=#""?&ft:"no ft"}',
|
|
\ 'percent': '%3p%%',
|
|
\ 'percentwin': '%P',
|
|
\ 'spell': '%{&spell?&spelllang:""}',
|
|
\ 'lineinfo': '%3l:%-2v',
|
|
\ 'line': '%l',
|
|
\ 'column': '%c'
|
|
\ 'close': '%999X X ' }
|
|
<
|
|
g:lightline.component_visible_condition *g:lightline.component_visible_condition*
|
|
Dictionary of boolean expressions for the components.
|
|
Each expression should correspond to the condition each
|
|
component have non-zero length.
|
|
The default value is:
|
|
>
|
|
let g:lightline.component_visible_condition = {
|
|
\ 'modified': '&modified||!&modifiable',
|
|
\ 'readonly': '&readonly',
|
|
\ 'paste': '&paste',
|
|
\ 'spell': '&spell' }
|
|
<
|
|
Users are recommended to set this option together with the
|
|
component itself.
|
|
|
|
g:lightline.component_function *g:lightline.component_function*
|
|
Another dictionary for components. This is more convenient
|
|
because the user does not have to set both component and
|
|
component_visible_condition. If a component set to both component and
|
|
component_function, the setting of component_function has priority.
|
|
For example, if you want a component for read-only mark, which
|
|
disappears in help windows:
|
|
>
|
|
let g:lightline = {
|
|
\ 'active': {
|
|
\ 'left': [ [ 'mode', 'paste' ],
|
|
\ [ 'myreadonly', 'filename', 'modified' ] ],
|
|
\ },
|
|
\ 'component_function': {
|
|
\ 'myreadonly': 'LightLineReadonly'
|
|
\ },
|
|
\ }
|
|
function! LightLineReadonly()
|
|
return &ft !~? 'help' && &readonly ? 'RO' : ''
|
|
endfunction
|
|
<
|
|
g:lightline.component_expand *g:lightline.component_expand*
|
|
Another dictionary for components. You can create a component
|
|
which has a special color. For example, error components or
|
|
warning components. The functions should return one of:
|
|
+ a string
|
|
+ an array of three elements:
|
|
[[ left ], [ middle ], [ right ]]
|
|
The component in this dictionary has priority over
|
|
|g:lightline.component| and |g:lightline.component_function|.
|
|
Note that the return string is appended to the statusline
|
|
string without any conversion. So you should replace all the
|
|
% signs with %%. Otherwise, lightline will be disabled in case
|
|
the text has a % sign.
|
|
(example: return substitute(text, '%', '%%', 'g')).
|
|
See |lightline-component-expansion| for more detail.
|
|
>
|
|
let g:lightline.component_expand = {
|
|
\ 'tabs': 'lightline#tabs' }
|
|
<
|
|
g:lightline.component_type *g:lightline.component_type*
|
|
A dictionary to specify the types for components in
|
|
|g:lightline.component_expand|. The types are used to specify
|
|
the color. Specifically, the type raw is used to specify a
|
|
component which should not be wrapped by item group: %(...%).
|
|
The default value is: >
|
|
|
|
let g:lightline.component_type = {
|
|
\ 'tabs': 'tabsel',
|
|
\ 'close': 'raw' }
|
|
<
|
|
g:lightline.tab_component *g:lightline.tab_component*
|
|
A dictionary for components in one tab.
|
|
The default value is: >
|
|
|
|
let g:lightline.tab_component = {}
|
|
<
|
|
g:lightline.tab_component_function *g:lightline.tab_component_function*
|
|
Another dictionary for components in one tab.
|
|
A function specified as a tab component takes one argument:
|
|
the tab [count].
|
|
The default value is:
|
|
>
|
|
let g:lightline.tab_component_function = {
|
|
\ 'filename': 'lightline#tab#filename',
|
|
\ 'modified': 'lightline#tab#modified',
|
|
\ 'readonly': 'lightline#tab#readonly',
|
|
\ 'tabnum': 'lightline#tab#tabnum' }
|
|
<
|
|
g:lightline.colorscheme *g:lightline.colorscheme*
|
|
The colorscheme for lightline.vim.
|
|
Currently, wombat, solarized, powerline, jellybeans, Tomorrow,
|
|
Tomorrow_Night, Tomorrow_Night_Blue, Tomorrow_Night_Eighties,
|
|
PaperColor, seoul256, landscape and 16color are available.
|
|
The default value is:
|
|
>
|
|
let g:lightline.colorscheme = 'default'
|
|
<
|
|
Note that the default colorscheme is exactly the same as the
|
|
powerline theme.
|
|
|
|
g:lightline.mode_map *g:lightline.mode_map*
|
|
A dictionary of names for the modes. The keys are the return
|
|
values of |mode()|.

==============================================================================
|
|
COMPONENT EXPANSION *lightline-component-expansion*
|
|
You can create components, which have specific colors. This section gives an
|
|
example using |syntastic|.
|
|
|
|
If you want to add the |syntastic| flag to the statusline, an easy example is:
|
|
>
|
|
" Example A
|
|
let g:lightline = {
|
|
\ 'active': {
|
|
\ 'right': [ [ 'lineinfo', 'syntastic' ],
|
|
\ [ 'percent' ],
|
|
\ [ 'fileformat', 'fileencoding', 'filetype' ] ]
|
|
\ },
|
|
\ 'component_function': {
|
|
\ 'syntastic': 'SyntasticStatuslineFlag',
|
|
\ }
|
|
\ }
|
|
let g:syntastic_mode_map = { 'mode': 'passive',
|
|
\ 'active_filetypes': ['c', 'cpp'] }
|
|
<
|
|
However, the color of the syntastic component is the same as the lineinfo
|
|
component.
|
|
|
|
In order to change the syntastic component more outstanding, you have to use
|
|
|g:lightline.component_expand|. See the following example:
|
|
>
|
|
" Example B
|
|
let g:lightline = {
|
|
\ 'active': {
|
|
\ 'right': [ [ 'syntastic', 'lineinfo' ],
|
|
\ [ 'percent' ],
|
|
\ [ 'fileformat', 'fileencoding', 'filetype' ] ]
|
|
\ },
|
|
\ 'component_expand': {
|
|
\ 'syntastic': 'SyntasticStatuslineFlag',
|
|
\ },
|
|
\ 'component_type': {
|
|
\ 'syntastic': 'error',
|
|
\ }
|
|
\ }
|
|
let g:syntastic_mode_map = { 'mode': 'passive' }
|
|
augroup AutoSyntastic
|
|
autocmd!
|
|
autocmd BufWritePost *.c,*.cpp call s:syntastic()
|
|
augroup END
|
|
function! s:syntastic()
|
|
SyntasticCheck
|
|
call lightline#update()
|
|
endfunction
|
|
<
|
|
In order to understand the above codes, you firstly should know how the
|
|
colorschemes work in lightline.vim. Open the following file.
|
|
autoload/lightline/colorscheme/powerline.vim
|
|
The colorscheme is created by one dictionary: s:p (abbreviation for palette).
|
|
See the value of s:p.normal.right.
|
|
>
|
|
let s:p.normal.right = [ ['gray5', 'gray10'],
|
|
\ ['gray9', 'gray4'],
|
|
\ ['gray8', 'gray2'] ]
|
|
<
|
|
This array corresponds to the structure of g:lightline.active.right. Recall
|
|
the example A.
|
|
>
|
|
" Example A
|
|
let g:lightline.active.right = [ [ 'lineinfo', 'syntastic' ],
|
|
\ [ 'percent' ],
|
|
\ [ 'fileformat', 'fileencoding', 'filetype' ] ]
|
|
<
|
|
The colors are ([fgcolor, bgcolor):
|
|
>
|
|
(0) [ 'lineinfo', 'syntastic' ] --- s:p.normal.right[0] = ['gray5', 'gray10']
|
|
(1) [ 'percent' ] --- s:p.normal.right[1] = ['gray9', 'gray4']
|
|
(2) [ 'fileformat', 'fileencoding', 'filetype' ] --- s:p.normal.right[2] = ['gray8', 'gray2']
|
|
<
|
|
Recall the example B.
|
|
>
|
|
" Example B
|
|
let g:lightline.active.right = [ [ 'syntastic', 'lineinfo' ],
|
|
\ [ 'percent' ],
|
|
\ [ 'fileformat', 'fileencoding', 'filetype' ] ]
|
|
<
|
|
If a component is specified in |g:lightline.component_expand|, lightline.vim
|
|
expands the components before setting to statusline/tabline. In this example,
|
|
the syntastic component is expanded using the |SyntasticStatuslineFlag| function.
|
|
This function returns a {string}. Let us call it `syntastic_flag`.
|
|
>
|
|
let syntastic_flag = SyntasticStatuslineFlag()
|
|
<
|
|
The syntastic component is now expanded, so it go up to one component group.
|
|
The type of the syntastic component is error, and the palette has error
|
|
colors, the result is:
|
|
>
|
|
" Expanded result of Example B
|
|
(error) [ syntastic_flag ] --- s:p.normal.error[0] = ['gray9', 'brightestred']
|
|
(0) [ 'lineinfo' ] --- s:p.normal.right[0] = ['gray5', 'gray10']
|
|
(1) [ 'percent' ] --- s:p.normal.right[1] = ['gray9', 'gray4']
|
|
(2) [ 'fileformat', 'fileencoding', 'filetype' ] --- s:p.normal.right[2] = ['gray8', 'gray2']
|
|
<
|
|
Thus the syntastic component has the red color.
|
|
|
|
|
|
Another example for |g:lightline.component_expand| is the tabs component.
|
|
Actually, the expand feature is created for the tabs component.
|
|
>
|
|
let g:lightline.tabline.left = [ [ 'tabs' ] ]
|
|
let g:lightline.component_expand = {
|
|
\ 'tabs': 'lightline#tabs' }
|
|
<
|
|
Create three tabs and select the middle tab. Then execute
|
|
>
|
|
echo lightline#tabs()
|
|
" [['%1T%{lightline#onetab(1,0)}'],
|
|
" ['%2T%{lightline#onetab(2,1)}'],
|
|
" ['%3T%{lightline#onetab(3,0)}%T']]
|
|
<
|
|
It returns an array of three elements. The expanded result is:
|
|
>
|
|
" Expanded result of tabline
|
|
(0) ['%1T%{lightline#onetab(1,0)}'] --- s:p.tabline.left[0] = ['gray9', 'gray4']
|
|
(tabsel) ['%2T%{lightline#onetab(2,1)}'] --- s:p.tabline.tabsel[0] = ['gray9', 'gray1']
|
|
(0) ['%3T%{lightline#onetab(3,0)}%T'] --- s:p.tabline.left[0] = ['gray9', 'gray4']
|
|
<
|
|
If the tabline components are
|
|
>
|
|
let g:lightline.tabline.left = [ [ 'A', 'B', 'tabs', 'C', 'D' ] ]
|
|
<
|
|
then the expanded result is:
|
|
>
|
|
(0) ['A', 'B', '%1T%{lightline#onetab(1,0)}'] --- s:p.tabline.left[0]
|
|
(tabsel) ['%2T%{lightline#onetab(2,1)}'] --- s:p.tabline.tabsel[0]
|
|
(0) ['%3T%{lightline#onetab(3,0)}%T', 'C', 'D'] --- s:p.tabline.left[0]
|
|
<
|
|
In summary, when a function in |g:lightline.component_expand| returns an
|
|
array of three elements, the first element and the last element remains as a
|
|
part of existing component group. And the middle element goes up to new
|
|
component group.

COLORSCHEME *lightline-colorscheme*
|
|
You can configure the colorscheme of lightline. For example,
|
|
>
|
|
let g:lightline = {
|
|
\ 'colorscheme': 'wombat',
|
|
\ }
|
|
<
|
|
The colorscheme files are found in the directory
|
|
|
|
lightline.vim/autoload/lightline/colorscheme/
|
|
|
|
In each file, one global variable is defined. For example, in the landscape.vim
|
|
file, you see
|
|
>
|
|
let g:lightline#colorscheme#landscape#palette = s:p
|
|
<
|
|
In the file, the colors for the landscape colorscheme are defined. For example,
|
|
>
|
|
let s:p.normal.left = [ ['#0000ff', '#ffffff', 21, 231, 'bold' ], [ '#ffffff', '#0000ff', 231, 21 ] ]
|
|
<
|
|
defines the colors for the components on the left hand side, in normal mode.
|
|
>
|
|
let s:p.tabline.tabsel = [ [ '#dadada', '#121212', 253, 233 ] ]
|
|
<
|
|
defines the colors for the selected tab in tabline. In general, each palette
|
|
follows the following style:
|
|
>
|
|
let s:p.{mode}.{where} = [ [ {guifg}, {guibg}, {cuifg}, {cuibg} ], ... ]
|
|
<
|
|
|
|
|
|
Now, you can create your own colorscheme for lightline. Create a
|
|
yourcolorscheme.vim at
|
|
|
|
{one of the paths in &rtp}/autoload/lightline/colorscheme/yourcolorscheme.vim
|
|
|
|
The following code gives the minimal palette definition for lightline.
|
|
>
|
|
let s:p = {'normal': {}}
|
|
let s:p.normal.left = [ [ ... ] ]
|
|
let s:p.normal.right = [ [ ... ] ]
|
|
let s:p.normal.middle = [ [ ... ] ]
|
|
let g:lightline#colorscheme#yourcolorscheme#palette = s:p
|
|
<
|
|
And if you add the colorscheme configuration to your .vimrc(_vimrc),
|
|
>
|
|
let g:lightline = {
|
|
\ 'colorscheme': 'yourcolorscheme',
|
|
\ }
|
|
<
|
|
you find it possible to change the lightline colors as you wish.
|
|
|
|
Moreover, if you want to change the colors based on the mode of vim, write
|
|
something like this:
|
|
>
|
|
let s:p.insert.left = [ [ ... ] ]
|
|
let s:p.insert.right = [ [ ... ] ]
|
|
let s:p.replace.left = [ [ ... ] ]
|
|
let s:p.replace.right = [ [ ... ] ]
|
|
...
|
|
...
|
|
<
|
|
For expanded components, you are recommended to define the following two
|
|
colors.
|
|
>
|
|
let s:p.normal.error = [ [ ... ] ]
|
|
let s:p.normal.warning = [ [ ... ] ]
|
|
<
|
|
For the complete list of components the color of which you should define in
|
|
your colorscheme, see the colorscheme files in lightline.
|
|
|
|
It is sometimes painful to write all the colors for both gui and cui.
|
|
Actually, lightline has some useful functions for writing colorschemes. For
|
|
example, see
|
|
lightline.vim/autoload/lightline/colorscheme/Tomorrow_Night.vim
|
|
this colorscheme is defined using only gui color numbers. And convert to the
|
|
normal colorscheme form using:
|
|
>
|
|
let g:lightline#colorscheme#Tomorrow_Night#palette = lightline#colorscheme#fill(s:p)
|
|
<
|
|
This function fills the cui colors for a palette which has only gui colors, or
|
|
vice versa. However, note that using the convenient function sources an
|
|
additional Vim script file (autoload/lightline/colorscheme.vim), which causes
|
|
a little slow down. If you want to avoid this situation, write all the colors
|
|
as done in autoload/lightline/colorscheme/landscape.vim; firstly create the
|
|
colorscheme using the fill function, and see the result, in a sense, the
|
|
compiled version of your colorscheme.
|
|
>
|
|
echo g:lightline#colorscheme#yourcolorscheme#palette
|
|
<
|
|
Then copy and paste the result to the colorscheme file.

Problem 6: *lightline-problem-6*
|
|
How to install a patched font.
|
|
|
|
There are two kinds of patched fonts:
|
|
|
|
+ The patched fonts for |vim-powerline|
|
|
(https://github.com/Lokaltog/vim-powerline):
|
|
follow the guide https://github.com/Lokaltog/vim-powerline/tree/develop/fontpatcher
|
|
+ The patched fonts for |powerline|
|
|
(https://github.com/Lokaltog/powerline):
|
|
download from https://github.com/Lokaltog/powerline-fonts
|
|
|
|
Problem 7: *lightline-problem-7*
|
|
Right triangles do not stick to the right components with patched
|
|
font.
|
|
|
|
Remove the following setting from your .vimrc(_vimrc).
|
|
>
|
|
set ambiwidth=double
|
|
<
|
|
If you want to keep this setting, try the patched font for
|
|
|vim-powerline|.
|
|
|
|
Problem 8: *lightline-problem-8*
|
|
Triangles do not appear. Triangles look weird.
|
|
|
|
If the triangles do not appear (but you get some spaces or
|
|
weird characters like <bf> or ¿), firstly try adding
|
|
>
|
|
scriptencoding utf-8
|
|
set encoding=utf-8
|
|
<
|
|
to the head of your .vimrc(_vimrc). Still you have weird
|
|
characters, use the unicode numbers. For |powerline| font
|
|
users:
|
|
>
|
|
\ 'separator': { 'left': "\ue0b0", 'right': "\ue0b2" },
|
|
\ 'subseparator': { 'left': "\ue0b1", 'right': "\ue0b3" }
|
|
<
|
|
For |vim-powerline| font users:
|
|
>
|
|
\ 'separator': { 'left': "\u2b80", 'right': "\u2b82" },
|
|
\ 'subseparator': { 'left': "\u2b81", 'right': "\u2b83" }
|
|
<
|
|
The full list of unicode numbers for fancy characters is shown
|
|
in |lightline-problem-9|.
|
|
|
|
If the triangles are shown in appropriate characters but the
|
|
colors do not look correctly, see the following.
|
|
If you are using iTerm2, change the following settings.
|
|
|
|
+ set Profiles>Colors>Minimum contrast to the Lowest.
|
|
+ set Profiles>Window>Transparency to the Opaquest.
|
|
|
|
For other terminals, this weird-triangle problem will be
|
|
resolved by disabling transparency or contrast adjustment.
|
|
|
|
Problem 9: *lightline-problem-9*
|
|
Where can I find the list of all the cool characters for patched fonts?
|
|
|
|
Default powerline vim-powerline
|
|
separator.left '' '' (\ue0b0) '⮀' (\u2b80)
|
|
separator.right '' '' (\ue0b2) '⮂' (\u2b82)
|
|
subseparator.left '|' '' (\ue0b1) '⮁' (\u2b81)
|
|
subseparator.right '|' '' (\ue0b3) '⮃' (\u2b83)
|
|
branch symbol -- '' (\ue0a0) '⭠' (\u2b60)
|
|
readonly symbol -- '' (\ue0a2) '⭤' (\u2b64)
|
|
linecolumn symbol -- '' (\ue0a1) '⭡' (\u2b81)
|
|
|
|
Problem 10: *lightline-problem-10*
|
|
Cool statusline disappears on |unite|, |vimfiler| and |vimshell|
|
|
buffers.
|
|
|
|
Add the following settings to your .vimrc(_vimrc).
|
|
>
|
|
let g:unite_force_overwrite_statusline = 0
|
|
let g:vimfiler_force_overwrite_statusline = 0
|
|
let g:vimshell_force_overwrite_statusline = 0
|
|
<
|
|
Problem 11: *lightline-problem-11*
|
|
Cool statusline disappears in |CtrlP|, |Tagbar| buffers.
|
|
|
|
Add the following settings to your .vimrc(_vimrc).
|
|
>
|
|
let g:ctrlp_status_func = {
|
|
\ 'main': 'CtrlPStatusFunc_1',
|
|
\ 'prog': 'CtrlPStatusFunc_2',
|
|
\ }
|
|
function! CtrlPStatusFunc_1(focus, byfname, regex, prev, item, next, marked)
|
|
return lightline#statusline(0)
|
|
endfunction
|
|
function! CtrlPStatusFunc_2(str)
|
|
return lightline#statusline(0)
|
|
endfunction
|
|
|
|
let g:tagbar_status_func = 'TagbarStatusFunc'
|
|
function! TagbarStatusFunc(current, sort, fname, ...) abort
|
|
return lightline#statusline(0)
|
|
endfunction
|
|
<
|
|
See |lightline-powerful-example| for more cool settings for
|
|
these plugins.

|
Problem 12: *lightline-problem-12*
|
|
How to make the plus sign red like |powerline|?
|
|
|
|
Use the following setings.
|
|
>
|
|
let g:lightline = {
|
|
\ 'component': {
|
|
\ 'modified': '%#ModifiedColor#%{LightLineModified()}',
|
|
\ }
|
|
\ }
|
|
function! LightLineModified()
|
|
let map = { 'V': 'n', "\<C-v>": 'n', 's': 'n', 'v': 'n', "\<C-s>": 'n', 'c': 'n', 'R': 'n'}
|
|
let mode = get(map, mode()[0], mode()[0])
|
|
let bgcolor = {'n': [240, '#585858'], 'i': [31, '#0087af']}
|
|
let color = get(bgcolor, mode, bgcolor.n)
|
|
exe printf('hi ModifiedColor ctermfg=196 ctermbg=%d guifg=#ff0000 guibg=%s term=bold cterm=bold',
|
|
\ color[0], color[1])
|
|
return &modified ? '+' : &modifiable ? '' : '-'
|
|
endfunction
|
|
<
|
|
It's surely complicated. There's no easy API to do a thing
|
|
like this. But it means that your request does not match
|
|
the spirit of lightline.
|
|
|
|
Problem 13: *lightline-problem-13*
|
|
How to change the lightline colorscheme on the fly.
|
|
|
|
Add the following settings to your .vimrc(_vimrc).
|
|
>
|
|
augroup LightLineColorscheme
|
|
autocmd!
|
|
autocmd ColorScheme * call s:lightline_update()
|
|
augroup END
|
|
function! s:lightline_update()
|
|
if !exists('g:loaded_lightline')
|
|
return
|
|
endif
|
|
try
|
|
if g:colors_name =~# 'wombat\|solarized\|landscape\|jellybeans\|seoul256\|Tomorrow'
|
|
let g:lightline.colorscheme =
|
|
\ substitute(substitute(g:colors_name, '-', '_', 'g'), '256.*', '', '')
|
|
call lightline#init()
|
|
call lightline#colorscheme()
|
|
call lightline#update()
|
|
endif
|
|
catch
|
|
endtry
|
|
endfunction
|
|
<
|
|
Problem 14: *lightline-problem-14*
|
|
The 'E541' warning appears on the right hand side.
|
|
Many components disable the statusline of lightline.
|
|
|
|
The number of items in statusline/tabline is limited to 80
|
|
(see |E541|). You cannot register too much components.
|
|
|
|
Problem 15: *lightline-problem-15*
|
|
Do not deal with the tabline.
|
|
Do not use the fancy separators in the tabline.
|
|
|
|
You can disable the tabline feature of lightline.vim using:
|
|
>
|
|
let g:lightline = {
|
|
\ 'enable': { 'tabline': 0 },
|
|
\ }
|
|
<
|
|
If you don't like the separators in the tabline, use:
|
|
>
|
|
let g:lightline = {
|
|
\ 'tabline_separator': { 'left': "", 'right': "" },
|
|
\ 'tabline_subseparator': { 'left': "", 'right': "" },
|
|
\ }
|
|
<
|
|
Problem 16: *lightline-problem-16*
|
|
When changed the component to a function component to an expanding
|
|
component, the statusline of lightline is sometimes disabled.
|
|
|
|
When you changed from
|
|
>
|
|
\ 'component_function': {
|
|
\ 'my': 'My',
|
|
\ }
|
|
<
|
|
to
|
|
>
|
|
\ 'component_expand': {
|
|
\ 'my': 'My',
|
|
\ }
|
|
<
|
|
the statusline of lightline is disabled unexpectedly.
|
|
In such a case, the text returned by 'My' function may include
|
|
the '%' character. Replace all the '%' signs with '%%'.
|
|
>
|
|
function My()
|
|
...
|
|
return substitute(text, '%', '%%', 'g')
|
|
endfunction
|
|
<
|
