<% # RNB, A VIM COLORSCHEME TEMPLATE # Author: Romain Lafourcade (https://github.com/romainl) # Canonical URL: https://github.com/romainl/vim-rnb # This template is designed to help vimmers create their own colorschemes # without much effort. # # You will need Ruby to generate your colorscheme but Ruby knowledge is # not needed at all. # # The process is divided in five steps: # 1. rename `colors/rnb.erb` to `colors/name_of_your_colorscheme.erb`, # 2. start by editing your colorscheme's information, # 3. define your colors, # 4. define your highlight groups and links, # 5. and generate your colorscheme. # Step 2: information # # Make sure the name of your colorscheme is unique and attractive. # The description should fit in a single line with no linefeed. # 'background' can be "light" or "dark". information = { author: "foo", email: "foo@foo.foo", name: "rnb", description: "Lorem ipsum dolor sit amet.", background: "light", webpage: "http://www.example.com" } # Step 3: colors # # black = [ give each color a distinctive name # "#000000", hexadecimal color used in GVim/MacVim or "NONE" # 0, integer between 0 and 255 used by terminals supporting 256 colors # or "NONE" # "black" color name used by less capable color terminals, can be "darkred", # "red", "darkgreen", "green", "darkyellow", "yellow", "darkblue", # "blue", "darkmagenta", "magenta", "black", "darkgrey", "grey", # "white", or "NONE" # ] # # If your colors are defined correctly, the resulting colorscheme is guaranteed # to work in GVim (Windows/Linux), MacVim, and any properly set up terminal emulator. # # The colors below are the first 16 colors of the xterm palette.

Use color names # instead of numbers: :help cterm-colors # * The Windows console (yeah…) doesn't do italics, underlines or bolded text; # it is limited to normal and reverse. Keep that in mind if you want # your colorscheme to be usable in as many environments as possible by as many # people as possible. # * Actually, terminal emulators rarely do italics. # * All of the terminal emulators in use these days allow their users to # change the 16 so-called "ANSI" colors. It is also possible on some platforms # to change some or all of the 256 colors in the xterm palette. Don't take # anything for granted. # * When used against a light background, strong colors work better than muted # ones. Light or dark doesn't really matters. Also, it is harder to discriminate # between two similar colors on a light background. # * Both strong and muted colors work well against a dark background. It is also # easier to work with similar colors, but dark colors don't work at all. # * Use as many text samples as possible. String-heavy languages may look completely # different than keyword-heavy ones. This can have an impact on the usability # of your colorscheme. # * Most terminal emulators and terminal multiplexers currently in use on unix-like # systems support 256 colors but they almost always default to a '$TERM' that tells # Vim otherwise. Your users will need to make sure their terminal emulator/multiplexer # is correctly set up if they want to enjoy the best possible experience. # Many thanks to Barry Arthur (https://github.com/dahu) for the original idea. # You don't need to edit anything beyond this line. -%> " <%= information[:name] %>.vim -- Vim color scheme.
