Theming

General Theme Settings

set termguicolors
set background=dark
colorscheme onedark

Setup termguicolors to make them 256, dark background for compatibility, and my current colorscheme is onedark

I like a transparent vim background, so I set it for both color modes

This is set such that the CursorLine is grey and the text is bold

let g:indent_guides_auto_colors = 0
let g:indent_guides_guide_size = 1
autocmd VimEnter,Colorscheme * :hi IndentGuidesOdd guibg=NONE ctermbg = 3
autocmd VimEnter,Colorscheme * :hi IndentGuidesEven guibg=violet ctermbg = 4

Set the size and colors for my indent guides, straightforward enough

let g:minimap_width = 10
let g:minimap_auto_start = 1
let g:minimap_auto_start_win_enter = 1

Minimap stuff, they're about what they read.

let g:rainbow#pairs = [['{','}'], ['(',')'], ['[',']']]
let g:rainbow#blacklist = [236, 148, 197]

Setup all pairs of brackets for coloration, and the color blacklist are one's I felt didn't match my scheme or that didn't stand out very well, subjective/setup dependent.

Startify Settings

let g:startify_custom_header = [
  \ '"""""""""""""""""""""""""""""""""""""""',
  \ '"""""""""""""""""""""""""""""""""""""""',
  \ '""""""""██╗"""██╗██╗███╗"""███╗""""""""',
  \ '""""""""██║"""██║██║████╗"████║""""""""',
  \ '""""""""██║"""██║██║██╔████╔██║""""""""',
  \ '""""""""╚██╗"██╔╝██║██║╚██╔╝██║""""""""',
  \ '"""""""""╚████╔╝"██║██║"╚═╝"██║""""""""',
  \ '""""""""""╚═══╝""╚═╝╚═╝"""""╚═╝""""""""',
  \ '"""""""""""""""""""""""""""""""""""""""',
  \ '"""""""""""""""""""""""""""""""""""""""'
  \ ]

Custom startify header, this can be anything you want in this format

let g:startify_lists = [
  \ { 'header':[], 'type':'files'},
  \ ]

Custom setup for headers in startify, I only care about my recently used files and dont need a header.
