JB for Vim

A set of colour schemes for Vim, inspired by Jetbrains' IDEs.

Features

Familiar Look

Not only are the colours accurate to the default JetBrains themes, they also attempt to emulate the original colour hierarchy. For instance, JSON keywords are highlighted in the Constant colour, not the keyword colour. This of course is limited by the available highlight groups in Vim, and even with vim-polyglot it is not possible to get an exact match, so expect a best-effort outcome.

Multiple Palettes

Three palette options are packaged:

• dark: Uses the colours from the 'Dark' JetBrains theme
• light: For those who prefer a light theme, follows the 'Light' theme
• mid: A bonus theme - The dark palette with a lighter background

Bring Your Own Colours

Any of the palette colours can be overridden. See Configuration or :help g:jb_color_overrides for how to implement your own colours. Highlight groups can also be modified in an autoload group to change the look of the plugin.

Semantic language syntax highlighting

Includes more in depth highlighting rules, ported from the original themes, in accordance with the highlight groups of the language syntax packs in vim-polyglot. It is recommended you install polyglot alongside this colorscheme for the best highlighting.

Truecolor, cterm, and italic support

Whilst built with true colours in mind, vim-jb's schemes also support 256 colour terminals. You can also opt-in to italics if your terminal emulator supports them. See Configuration or :help jb-configuration for more details.

Plugins out the box

Includes highlight links for popular Vim plugins such as GitGutter, NERDTree, ALE, FZF, Fugitive, and more. For those without included groups, the JB* top-level highlight groups in the plugin configuration allow for easy and clear custom mapping in a .vimrc that won't affect other schemes. See colors/jb.vim for the groups.

Installation

Using vim-plug (or your package manager of choice):

Plug 'devsjc/vim-jb'

Usage

Place the following line at the bottom of your .vimrc:

colorscheme jb

Configuration

Note: All configuration must be placed before the colorscheme jb line. Further configuration details can be found via :help jb-configuration.

Choosing the style

The style is set with g:jb_style variable. For instance:

let g:jb_style='mid'
colorscheme jb

Enabling italics

If your terminal emulator supports italics, opt in using

let g:jb_enable_italics=1
colorscheme jb

Enabling Unicode

If your terminal emulator/font support unicode, opt in using

let g:jb_enable_unicode=1
colorscheme jb

Modifying a color

To choose your own colour, pick a category from the palettes file, and define your overrides in a dictionary containing your replacement gui and cterm colours:

let g:jb_color_overrides={
    \"keyword": {"gui": "#ff00ff", "cterm": "16"}
    \}

You can also change highlight groups, overriding what is set in the plugin. Say you prefer how Android Studio uses the Type colour for Kotlin structures, instead of the less saturated Keyword of IntelliJ Idea. Simply add the following overrides in an augroup in your .vimrc:

augroup JBHiglights
    autocmd!
    autocmd ColorScheme * highlight link ktStructure Type
augroup END

This must be placed in an augroup to prevent vim-jb from overriding it.
