colorgen-nvim

🚀 A colorscheme generator for Neovim written in Rust 🦀

Installing

From crates.io:

cargo install colorgen-nvim

For development version

cargo install --git https://github.com/ChristianChiarulli/colorgen-nvim

Usage

Create a toml file containing your highlight groups, there is an example in this repo called user_template.toml

NOTE: You can call this file whatever you want

colorgen-nvim user_template.toml

Template

The template must contain a information section and a palette section

Example:

[information]
 name = "onedarker"
 background = "dark"
 author = 'Christian Chiarulli <[email protected]>'

[palette]
 fg = '#abb2bf'
 bg = '#1e222a'

 white = '#abb2bf'
 gray = '#545862'
 blue = '#519fdf'
 green = '#88b369'
 cyan = '#46a6b2'
 red = '#d05c65'
 orange = '#c18a56'
 yellow = '#d5b06b'
 purple = '#b668cd'
 magenta = '#D16D9E'

You can define color options in the palette section and use them later to set colors for different highlight groups

Example:

[highlights]
 Normal = 'fg bg'
 SignColumn = '- bg'
 MsgArea = 'fg bg'
 ModeMsg = 'fg bg'
 MsgSeparator = 'fg bg'
 SpellBad = 'red - u'
 SpellCap = 'yellow - u'
 SpellLocal = 'green - u'
 SpellRare = 'purple - u'
 NormalNC = 'fg bg'
 Pmenu = 'red bg - - 50'
 PmenuSel = '- blue'
 WildMenu = 'fg blue'
 CursorLineNr = 'light_gray - b'
 Comment = 'gray - i'

[Treesitter]
 TSComment = 'link:Comment'
 TSAnnotation = 'blue'
 TSAttribute = 'cyan'
 TSConstructor = 'cyan'
 TSType = 'cyan'

The format is foreground background style special blend

You can also choose to link a highlight group to another by passing link:<name of hl group>

The - is used to skip a particular section and replace it with NONE

Style Options:

• o: standout
• u: underline
• c: undercurl
• d: underdouble
• t: underdotted
• h: underdashed
• s: strikethrough
• i: italic
• b: bold
• r: reverse
• n: nocombine

TODO:

• support transparent background (this could get tricky with other plugins, considering bg:optional, if you put that then setting the transparent flag will set it to none)

• italic comments
