" Vim color file " Maintainer: Henry So, Jr. " These are the colors of the "desert" theme by Hans Fugal with a few small " modifications (namely that I lowered the intensity of the normal white and " made the normal and nontext backgrounds black), modified to work with 88- " and 256-color xterms. " " The original "desert" theme is available as part of the vim distribution or " at http://hans.fugal.net/vim/colors/. " " The real feature of this color scheme, with a wink to the "inkpot" theme, is " the programmatic approximation of the gui colors to the palettes of 88- and " 256- color xterms. The functions that do this (folded away, for " readability) are calibrated to the colors used for Thomas E. Dickey's xterm " (version 200), which is available at http://dickey.his.com/xterm/xterm.html. " " I struggled with trying to parse the rgb.txt file to avoid the necessity of " converting color names to #rrggbb form, but decided it was just not worth " the effort. Maybe someone seeing this may decide otherwise... set background=dark if version > 580 " no guarantees for version 5.8 and below, but this makes it stop " complaining hi clear if exists("syntax_on") syntax reset endif endif let g:colors_name="desert256" if has("gui_running") || &t_Co == 88 || &t_Co == 256 " functions {{{ " returns an approximate grey index for the given grey level fun grey_number(x) if &t_Co == 88 if a:x < 23 return 0 elseif a:x < 69 return 1 elseif a:x < 103 return 2 elseif a:x < 127 return 3 elseif a:x < 150 return 4 elseif a:x < 173 return 5 elseif a:x < 196 return 6 elseif a:x < 219 return 7 elseif a:x < 243 return 8 else return 9 endif else if a:x < 14 return 0 else let l:n = (a:x - 8) / 10 let l:m = (a:x - 8) % 10 if l:m < 5 return l:n else return l:n + 1 endif endif endif endfun " returns the actual grey level represented by the grey index fun grey_level(n) if &t_Co == 88 if a:n == 0 return 0 elseif a:n == 1 return 46 elseif a:n == 2 return 92 elseif a:n == 3 return 115 elseif a:n == 4 return 139 elseif a:n == 5 return 162 elseif a:n == 6 return 185 elseif a:n == 7 return 208 elseif a:n == 8 return 231 else return 255 endif else if a:n == 0 return 0 else return 8 + (a:n * 10) endif endif endfun " returns the palette index for the given grey index fun grey_color(n) if &t_Co == 88 if a:n == 0 return 16 elseif a:n == 9 return 79 else return 79 + a:n endif else if a:n == 0 return 16 elseif a:n == 25 return 231 else return 231 + a:n endif endif endfun " returns an approximate color index for the given color level fun rgb_number(x) if &t_Co == 88 if a:x < 69 return 0 elseif a:x < 172 return 1 elseif a:x < 230 return 2 else return 3 endif else if a:x < 75 return 0 else let l:n = (a:x - 55) / 40 let l:m = (a:x - 55) % 40 if l:m < 20 return l:n else return l:n + 1 endif endif endif endfun " returns the actual color level for the given color index fun rgb_level(n) if &t_Co == 88 if a:n == 0 return 0 elseif a:n == 1 return 139 elseif a:n == 2 return 205 else return 255 endif else if a:n == 0 return 0 else return 55 + (a:n * 40) endif endif endfun " returns the palette index for the given R/G/B color indices fun rgb_color(x, y, z) if &t_Co == 88 return 16 + (a:x * 16) + (a:y * 4) + a:z else return 16 + (a:x * 36) + (a:y * 6) + a:z endif endfun " returns the palette index to approximate the given R/G/B color levels fun color(r, g, b) " get the closest grey let l:gx = grey_number(a:r) let l:gy = grey_number(a:g) let l:gz = grey_number(a:b) " get the closest color let l:x = rgb_number(a:r) let l:y = rgb_number(a:g) let l:z = rgb_number(a:b) if l:gx == l:gy && l:gy == l:gz " there are two possibilities let l:dgr = grey_level(l:gx) - a:r let l:dgg = grey_level(l:gy) - a:g let l:dgb = grey_level(l:gz) - a:b let l:dgrey = (l:dgr * l:dgr) + (l:dgg * l:dgg) + (l:dgb * l:dgb) let l:dr = rgb_level(l:gx) - a:r let l:dg = rgb_level(l:gy) - a:g let l:db = rgb_level(l:gz) - a:b let l:drgb = (l:dr * l:dr) + (l:dg * l:dg) + (l:db * l:db) if l:dgrey < l:drgb " use the grey return grey_color(l:gx) else " use the color return rgb_color(l:x, l:y, l:z) endif else " only one possibility return rgb_color(l:x, l:y, l:z) endif endfun " returns the palette index to approximate the 'rrggbb' hex string fun rgb(rgb) let l:r = ("0x" . strpart(a:rgb, 0, 2)) + 0 let l:g = ("0x" . strpart(a:rgb, 2, 2)) + 0 let l:b = ("0x" . strpart(a:rgb, 4, 2)) + 0 return color(l:r, l:g, l:b) endfun " sets the highlighting for the given group fun X(group, fg, bg, attr) if a:fg != "" exec "hi " . a:group .
