Change iterm2 palette when changing colorschemes

The problem

Changing colorscheme won't change the background color of the bordering window. For pedants like me, this isn't acceptable.

The solution

This plugin allows you to map a corresponding .itermcolors file to vim's colorscheme, and vim will update the current iterm2 profile to match. Works well with FZF.

Installation

Install with a vim plugin manager (or don't).

Configuration

Pedant looks for its configuration inside a vim dictionary g:pedant_options. Each colorscheme should have its name as the key, and an array as its value, with the first item being the full path the the corresponding .itermcolors file, and the second item is passed to set background=.

E.g. In your .vimrc add:

let g:pedant_options = {
      \ 'nova': ['/Users/<username>/itermcolors/nova.itermcolors', 'dark'],
      \ 'gruvbox': ['/Users/<username>/itermcolors/gruvbox.itermcolors', 'light'],
      \ 'deep-space': ['/Users/<username>/itermcolors/deep-space.itermcolors', 'dark'],
      \ }

Usage

Change colorscheme with Pcolorscheme instead of colorscheme.

E.g

:Pcolorscheme nova

Notes

This is a nasty hack.

Initially I just changed the iterm2 profile when changing colorschemes. This worked will with one caveat, font size. I often use ⌘+= and ⌘+- to zoom, but whenever the profile is changed, iterm will revert to the profile's font size. Honestly, font size shouldn't be part of the profile, and there is an open issue regarding this: https://gitlab.com/gnachman/iterm2/issues/5645

So instead this plugin will update the colors of the current session. This works very well and doesn't change your font size. The downside of this is when a new split is launched it will default to whichever profile is currently selected. Pull requests warmly welcomed!

Works well with colorscheme-switcher.vim.
