This is a work in progress port of the classic blue theme from TextMate. There are many great themes for Neovim out there, but I've not yet found one as easy on the eyes as this.
- Extensive support for
TreeSittersyntax highlighting, and many popular plugins - Compilation to lua byte code for super fast startup times
Download with your favorite package manager:
{
"wurli/cobalt.nvim"
config = function()
vim.cmd[[colorscheme cobalt]]
end
}There is no need to call setup if you are ok with the defaults.
-- Default options:
require('cobalt').setup({
compile = false, -- enable compiling the colorscheme
undercurl = true, -- enable undercurls
commentStyle = { italic = true },
functionStyle = {},
keywordStyle = { italic = true},
statementStyle = { bold = true },
typeStyle = {},
transparent = false, -- do not set background color
dimInactive = false, -- dim inactive window `:h hl-NormalNC`
terminalColors = true, -- define vim.g.terminal_color_{0,17}
colors = { -- add/modify theme and palette colors
palette = {},
theme = { default = {} }, -- Default is the only theme for now
},
overrides = function(colors) -- add/modify highlights
return {}
end,
theme = "classic", -- Load "wave" theme when 'background' option is not set
background = { -- map the value of 'background' option to a theme
dark = "classic", -- try "dragon" !
light = "lotus"
},
})
-- setup must be called before loading
vim.cmd("colorscheme cobalt")NOTE 1: If you enable compilation, make sure to run :CobaltCompile command every time you make changes to your config.
" 1. Modify your config
" 2. Restart nvim
" 3. Run this command:
:CobaltCompileNOTE 2: Cobalt adjusts to the value of some options. Make sure that the options 'laststatus' and 'cmdheight' are set before calling setup.
In cobalt, there are two kinds of colors: PaletteColors and ThemeColors;
PaletteColors are defined directly as RGB Hex strings, and have arbitrary names
that recall their actual color. Conversely, ThemeColors are named and grouped semantically
on the basis of their actual function.
In short, a palette defines all the available colors, while a theme maps the PaletteColors
to specific ThemeColors and the same palette color may be assigned to multiple theme colors.
You can change both theme or palette colors using config.colors.
All the palette color names can be found here,
while their usage by each theme can be found here.
require('cobalt').setup({
...,
colors = {
palette = {
-- change all usages of these colors
MintyFresh = "#3AD900", -- string
SereneSky = "#0088FF", -- comment
},
theme = {
-- change specific usages for a certain theme, or for all of them
default = {
ui = {
float = {
bg = "none",
},
},
},
}
},
...
}) You can conveniently add/modify hlgroups using the config.overrides option.
Supported keywords are the same for :h nvim_set_hl {val} parameter.
require('cobalt').setup({
...,
overrides = function(colors)
return {
-- Assign a static color to strings
String = { fg = colors.palette.PaleBlue, italic = true },
-- theme colors will update dynamically when you change theme!
SomePluginHl = { fg = colors.theme.syn.type, bold = true },
}
end,
...
})This will make floating windows look nicer with default borders.
overrides = function(colors)
local theme = colors.theme
return {
NormalFloat = { bg = "none" },
FloatBorder = { bg = "none" },
FloatTitle = { bg = "none" },
-- Save an hlgroup with dark background and dimmed foreground
-- so that you can use it where your still want darker windows.
-- E.g.: autocmd TermOpen * setlocal winhighlight=Normal:NormalDark
NormalDark = { fg = theme.ui.fg_dim, bg = theme.ui.bg_m3 },
-- Popular plugins that open floats will link to NormalFloat by default;
-- set their background accordingly if you wish to keep them dark and borderless
LazyNormal = { bg = theme.ui.bg_m3, fg = theme.ui.fg_dim },
MasonNormal = { bg = theme.ui.bg_m3, fg = theme.ui.fg_dim },
}
end,If you'd like to keep the floating windows darker, but you're unhappy with how borders are rendered, consider using characters that are drawn at the edges of the box:
{ "๐ญฝ", "โ", "๐ญพ", "โ", "๐ญฟ", "โ", "๐ญผ", "โ" }Block-like modern Telescope UI
overrides = function(colors)
local theme = colors.theme
return {
TelescopeTitle = { fg = theme.ui.special, bold = true },
TelescopePromptNormal = { bg = theme.ui.bg_m2 },
TelescopePromptBorder = { fg = theme.ui.bg_m2, bg = theme.ui.bg_m2 },
TelescopeResultsNormal = { fg = theme.ui.fg, bg = theme.ui.bg_m1 },
TelescopeResultsBorder = { fg = theme.ui.bg_m1, bg = theme.ui.bg_m1 },
TelescopePreviewNormal = { bg = theme.ui.bg_p2 },
TelescopePreviewBorder = { bg = theme.ui.bg_p2, fg = theme.ui.bg_p2 },
}
end,More uniform colors for the popup menu.
overrides = function(colors)
local theme = colors.theme
return {
Pmenu = { fg = theme.ui.shade0, bg = theme.ui.bg_p1 }, -- add `blend = vim.o.pumblend` to enable transparency
PmenuSel = { fg = "NONE", bg = theme.ui.bg_p2 },
PmenuSbar = { bg = theme.ui.bg_m1 },
PmenuThumb = { bg = theme.ui.bg_p2 },
}
end,The implementation of this plugin is based on the Kanagawa theme by Tommaso Laurenzi.
