This is a mirror of http://www.vim.org/scripts/script.php?script_id=2390 CSApprox.vim ============ DESCRIPTION ============ It's hard to find colorschemes for terminal Vim. Most colorschemes are written to only support GVim, and don't work at all in terminal Vim. This plugin makes GVim-only colorschemes Just Work in terminal Vim, as long as the terminal supports 88 or 256 colors - and most do these days. This usually requires no user interaction (but see the help for what to do if things don't Just Work). After getting this plugin happily installed, any time you use :colorscheme it will do its magic and make the colorscheme Just Work. Whenever you change colorschemes using the :colorscheme command this script will be executed. It will take the colors that the scheme specified for use in the GUI and use an approximation algorithm to try to gracefully degrade them to the closest color available in your terminal. If you are running in a GUI or if your terminal doesn't support 88 or 256 colors, no changes are made. Also, no changes will be made if the colorscheme seems to have been high color already. If for some reason this transparent method isn't suitable to you (for instance if your environment can't be configured to meet the |csapprox-requirements|, or you need to work in Vim 6), another option is also available: using the |:CSApproxSnapshot| command to create a new GUI/88-/256-color terminal colorscheme. To use this command, a user would generally start GVim, choose a colorscheme that sets up the desired colors, and then use |:CSApproxSnapshot| to create a new colorscheme based on those colors that works in high color terminals. This method is more flexible than the transparent mode and works in more places, but also requires more user intervention, and makes it harder to deal with colorschemes being updated and such. ====== NOTES ====== Ideally, this plugin should require absolutely no configuration, but you may need some tweaking to make sure vim realizes that your terminal supports more than 16 colors. Also, konsole and Eterm users will want to make sure that this plugin realizes that the terminal does not use colors that are exactly xterm-compatible; they will want to skim through the help articles |csapprox-palettes| and |csapprox-configuration| for a better end result. ============== SCREENSHOTS ============== Some quick side-by-side screenshots can be found at http://www.cs.drexel.edu/~mjw452/CSApprox/
