Breezy, a colorscheme for (neo)vim

Breezy is a (neo)vim true color scheme inspired by the KDE breeze palette. It uses the colors of the "Breeze Dark" color scheme shipped with KTextEditor since KDE Frameworks 5.23.

Appearance

This is what you get:

Installation

Use your favorite plugin manager or merge the contents of this repository with your ~/.vim or ~/.config/nvim directory.

Usage & Setup

The minimal setup required to use this colorscheme is:

set background=light
set termguicolors " if you want to run vim in a terminal
colorscheme breezy

Black background

You can use original KDE breeze background color by setting

set background=light

Otherwise for black background color set this to dark:

set background=dark

Please note that your terminal needs to support 24bit true color to correctly show the intended colors. An explanation and list of terminals supporting true colors can be found here.

Lightline Theme

This colorscheme comes with a matching lightline theme. To use it install the lightline plugin and add the following settings to your .vimrc or init.vim:

let g:lightline = {
      \ 'colorscheme': 'breezy',
      \ }

Airline Theme

There is now also a modest theme for airline included with this colorscheme. To use it, install the airline plugin and add this to your .vimrc or init.vim:

let g:airline_theme='breezy'

Refined Python highlighting

Breezy tries to closely mimic the syntax highlighting of python in KTextEditor. Some small efforts can be undertaken to accomplish an almost complete match:

Enable all python highlighting options (exceptions, space errors, ...).

let python_highlight_all=1

Some differences in syntax highlighting styles can be overwritten in ~/.vim/after/syntax/python.vim for vim or ~/.config/nvim/after/syntax/python.vim for neovim. All these options are entirely optional but showcase what I use to achieve the result below:

" Remove doctest highlighting by commenting out pythonDoctest and pythonDocTest:
syn region pythonDocstring  start=+^\s*[uU]\?[rR]\?"""+ end=+"""+ keepend
  \ excludenl contains=pythonEscape,@Spell,pythonSpaceError",pythonDoctest,pythonDocTest2
syn region pythonDocstring  start=+^\s*[uU]\?[rR]\?'''+ end=+'''+ keepend
  \ excludenl contains=pythonEscape,@Spell,pythonSpaceError",pythonDoctest,pythonDocTest2
" Make these special variables more special

" Highlight def statements different from normal python statements

" Highlight 'as' different from normal python statements

" Highlight the whole name of a decorator, not just the '@'

" Highlight 'magic' overload functions

Contributing

As of now this is merely my personal attempt to make vim fit in with the KDE Breeze theme I use. But I haven't seen a similar theme yet and welcome any help with improving the theme in general or for specific languages.

When supporting additional languages, I would generally like to stay reasonably close to the style provided by Kate/ KWrite. Feel free to open any issue or pull request, though. If you'd like better support for a particular language, a code example would be helpful to compare the highlighting style of this theme and KDE Breeze Dark.

Thanks

I would like to thank the following people:

• The KDE Visual Design Group who created the "Breeze" theme
• Romain Lafourcade, whose color scheme Apprentice provided me with an easy start and a solid base for realizing this
