Tip: #884 - Use different color schemes depending on time of day

Created: February 24, 2005 11:43 Complexity: intermediate Author: Johannes Petzold Version: 7.0 Karma: 51/20 Imported from: Tip#884

If your Vim's version has been compiled with the +perl - feature (type ":echo has('perl')" to find out), you can use the following lines to let Vim choose a different color scheme on startup, depending on the actual time of day. For example, if you want something like this:

• "elflord" from 19 to 4 o'clock in the morning
• "morning" from 4 to 8
• "desert" from 8 to 15
• "evening" from 15 to 19

place the following lines somewhere into your _vimrc:

perl <<EOFPERL 
VIM::DoCommand "color " . { 
 map @{ref and push(@$a,@$_),[] or $c=$_,[map{$a=[];$_,$c}@{[@$a]}]}, 
 [0 .. 3] => "elflord", 
 [4 .. 7] => "morning", 
 [8 .. 14] => "desert", 
 [15 .. 18] => "evening", 
 [19 .. 23] => "elflord" 
 }->{(localtime)[2]} 
EOFPERL 

Customize the [interval] => "name-of-colorscheme" - lines to your individual needs.

Notes:

• [0 .. 3] means 00:00 to 03:59.
• Intervals should cover all hours from 0 to 23.

Comments

One doesn't usually need perl to do this, either. As an example...

let hr= strftime("%H") 
if 0 <= hr && hr <= 3 
 colors elflord 
elseif 4 <= hr && hr <= 7 
 colors morning 
elseif 8 <= hr && hr <= 14 
 colors desert 
elseif 15 <= hr && hr <= 18 
 colors evening 
else 
 colors astronaut 
endif

Gkrellsun has a nice program for calculating current sun position and sun rise/set times

I use it to tune my colors (a bit lame, but works)

let s:hour=strftime("%H") 
let s:sunrise=system("echo $((`suninfo -lat 50 -lon 20 | head -n1 | cut -f1 -d:`+1))") 
let s:sunset=system("echo $((`suninfo -lat 50 -lon 20 | tail -n1 | cut -f1 -d:`+11))") 
if (s:hour<s:sunset) && (s:hour>s:sunrise) 
 colorscheme BlackSea 
else 
 colorscheme dante 
fi

What a wonderful tip! It seems that I'll never use it, but what an idea!...

By the way, you may use

autocmd CursorHold * ... 

to make Vim change colors at run-time, almost exactly at the time, not only at startup.

Emacs has calender-mode complete with sunrise,lunar phases all in emacs-lisp, let's see something non trivial from vim users too. Or are we all just web site makers here?
