This script picks a colorscheme randomly among all available schemes files when vim starts up. This is similar to VimTip341, but differs in that it is independent of other script liblaries, besides the randomness.
Copy the lines below to somewhere appropriate in your vimrc:
" Create the comma-separated list of colorscheme files
let s:colors = substitute(globpath(&runtimepath, 'colors/*.vim'), '\n', ',', 'g')
if strlen(s:colors)
" Count the number of color schemes
let s:num = strlen(substitute(s:colors, '[^,]\+', '', 'g')) + 1
if s:num > 1
let s:loop = localtime() % s:num
" Rotate the list s:loop times
while s:loop
let s:colors = substitute(s:colors, '^\([^,]\+\),\(.*\)$', '\2,\1', '')
let s:loop = s:loop - 1
endwhile
endif
let s:color = matchstr(s:colors, '^[^,]\+')
unlet! g:colors_name
execute 'source' s:color
" Prevent the message from disappearing
redraw
echomsg 'Color applied: '.(exists('g:colors_name') ? g:colors_name : '').' ('.s:color.')'
endif
unlet! s:colors s:color s:num s:loop
Adding this script might slightly slow down the startup.
Comments
It's better to add
redraw echo g:colors_name
at the last.
