# 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. They
|
|
# are only here as an example, though. You can get rid of them, I won't be mad.
|
|
black = ["#000000", 0, "black"]
|
|
darkred = ["#800000", 1, "darkred"]
|
|
darkgreen = ["#008000", 2, "darkgreen"]
|
|
darkyellow = ["#808000", 3, "darkyellow"]
|
|
darkblue = ["#000080", 4, "darkblue"]
|
|
darkmagenta = ["#800080", 5, "darkmagenta"]
|
|
darkcyan = ["#008080", 6, "darkcyan"]
|
|
gray = ["#c0c0c0", 7, "gray"]
|
|
darkgray = ["#808080", 8, "darkgray"]
|
|
red = ["#ff0000", 9, "red"]
|
|
green = ["#00ff00", 10, "green"]
|
|
yellow = ["#ffff00", 11, "yellow"]
|
|
blue = ["#0000ff", 12, "blue"]
|
|
magenta = ["#ff00ff", 13, "magenta"]
|
|
cyan = ["#00ffff", 14, "cyan"]
|
|
white = ["#ffffff", 15, "white"]
|
|
|
|
# Step 4: highlights
|
|
#
|
|
# You can define highlight groups like this:
|
|
#
|
|
# [ "Normal", name of the highlight group
|
|
# white, the color used for background color, or use "NONE", "fg" or "bg"
|
|
# darkgray, the color used for foreground color, or use "NONE", "fg" or "bg"
|
|
# "NONE" style, can be "bold", "underline", "reverse", "italic",
|
|
# "standout", "NONE" or "undercurl"
|
|
# ]
|
|
#
|
|
# The sample above tells Vim to render normal text in dark gray against a white
|
|
# background, without any styling.
|
|
#
|
|
# or link an highlight group to another:
|
|
#
|
|
# [ "Title", "Normal" ]
|
|
#
|
|
# In GUI Vim, there is an additional color for the undercurl used to
|
|
# highlight spelling mistakes:
|
|
#
|
|
# [ "SpellBad", name of the highlight group
|
|
# "NONE", the color used for background color, or use "NONE", "fg" or "bg"
|
|
# red, the color used for foreground color, or use "NONE", "fg" or "bg"
|
|
# "undercurl", style
|
|
# red color used for the undercurl
|
|
# ]
|
|
#
|
|
# The sample above tells Vim to render badly spelled words in red against the current
|
|
# background, with a red undercurl.
|
|
#
|
|
# You can add any custom highlight group to the standard list below but you shouldn't
|
|
# remove any if you want a working colorscheme.

# "I Made My Own Colour Scheme and You Can Too!"
|
|
|
|
# A few general advices:
|
|
#
|
|
# * The Windows console is limited to the 16 so-called "ANSI" colors but it has
|
|
# a few of them interverted which makes numbers impractical. 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.
|
|
# * 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.
