Theme Matching

You need to set day/night themes. Each day theme needs a single corresponding night theme.

Note that you're free to use themes not defined in either of these lists, but Werewolf will ignore them.

In your .vimrc:

let g:werewolf_day_themes = ['day1', 'day2', 'day3']
let g:werewolf_night_themes = ['night1', 'night2', 'night3']

Time of Day

Werewolf will transform between day and night based on two variables:

" default 8, use 24 hour format
let g:werewolf_day_start = 8

" default 20, 24 hour format
let g:werewolf_day_end = 20

The default settings have Werewolf transform to day at 8:00 AM and transform to night at 8:00 PM.

Automatic Transformation and Toggling

By default, Werewolf will automatically transform at the hours you specify. However, you can also control it manually if you wish:

" this defaults to 1, set it to 0 to control Werewolf manually
let g:werewolf_change_automatically = 0

You can then use :WerewolfToggle to switch between day and night themes at any time, or call :WerewolfTransform to change to the proper theme based on your day_start and day_end settings.
