### Available options:
#### Global Default options
Default options act as default for all components
- icons_enabled (Default: true)
Displays icons on components
You should have powerline supported fonts to see
icons properly.\
*Suported by branch, fileformat, filetype, location*\
Example:
```lua
lualine.options.icons_enabled = true
```
#### Genaral options
These options are available for all components.\
option&nbsp; &nbsp; &nbsp;(default_value)\
----------&nbsp; &nbsp; &nbsp; &nbsp;----------------------
- padding (1)\
spaces on left and right
- left_padding (1)\
spaces on left
- right_padding (1)\
spaces on right
- icon (depends on component)
displays an icon infront of component
- icons_enabled (true)
whether to show icon(if available)
- separator ('|')
which separator to use at end of component
- upper (false)\
Displayed in upper case
- lower (false)\
Displayed in lower case
- format (nil)\
Takes a function . The funtion gets the result of component
as argument and it's return value is displayed. So this function
can parse and format the output as user wants.
- color (Theme colors)\
color option can be used to set custom color to a component\
**Color format:**\
`lua color = {fg = '#rrggbb', bg= '#rrggbb', gui='style'}`\
the members of color table are optional and default to theme
#### Component specific options
These options are available for specific components only.\
List of options are given below.
- filename
- file_status (true)\
Whether to display filemodified status in filename
- shorten (true)\
Whether to display full/relative path with filename
- full_path (false)\
Whether to display full path when shorten is false
- fileformat
- icons_enabled (true)\
Whether to displays icon before component
**Example:**
```lua
lualine.sections.lualine_b = {
{
'branch',
icon = '',
upper = true,
color = { fg = '#00aa22' }
},
{
'filename',
full_name = true,
relative = true,
format = function(name)
-- Capitalize first charecter of filename to capital.
local path, fname = name:match('(.*/)(.*)')
rerurn path .. fname[1, 1]:upper() .. fname[2, #fname]
end
}
