" Vim color file
|

" Original Author: Henry So, Jr. <henryso@panix.com>

|
" It's a color scheme for Vim, based on the "desert" color scheme by Hans
|
||
|
|
" Fugal with a few small tweaks. The tweaks are try to make it looks a bit
|
||
|
|
" warm and be more friendly for my eyes. Using the code from "desert256" to
|
||
|
|
" make the gui highlight definitions also 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 "desert256" theme is available at
|
||
|
|
" http://www.vim.org/scripts/script.php?script_id=1243.
|
||
|
|
"
|
||
|
|
" 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.
|
||
|
|
"
|
||
|
|
" Support rgb color names from rgb.txt file. Use a Ruby script to pre-parse
|
||
|
|
" rgb.txt then convert color names mapping to a Vim dictionary, store it in
|
||
|
|
" colors/rgb_colors file.
|
||
|
|
"
|
||
|
|
" Consider use this color scheme as infrastructure to create new color
|
||
|
|
" schemes. The benefit is your color schemes will looks nearly the same both
|
||
|
|
" in gVim and Vim running in 256- color xterms, without any additional effort.
