prism.vim

prism.vim sets colorscheme basing on your working directory, to help you distinguishing a specific Vim instance among multiple ones from window previewer. It is like peacock for VSCode.

prism.vim chooses a colorscheme from provided colorscheme list by a number calculated from the current working directory.

Installation

With vim-plug or your favorite plugin manager, like

Plug 'UncleBill/prism.vim'

Requires Vim 8.0+ for full support.

Usage

Setting colorscheme space

Prism.vim will pick one from colorschemes below to set up.

" defaults to ['peachpuff', 'desert', 'evening', 'murphy']
" some of below are from https://github.com/flazz/vim-colorschemes
let g:prism_colorschemes = ['atom', 'desert', 'solarized', 'badwolf', 'lightyellow',
      \ 'dracula', 'peachpuff', 'pablo', 'SlateDark', 'torte', 'blink', 'blueprint',
      \ 'Benokai', 'greens', 'grayorange', 'graywh']

You can get a collection of colorschemes at flazz/vim-colorschemes

Shifting

Tired of one fixed colorscheme? You can make it shift to another in X days automatically:

let g:prism_shift_period = 0  " disable shifting, default value
let g:prism_shift_period = 30 " every 30 days, days since 1979-1-1,

Reset at runtime

Use PrismSet command to reset colorscheme at runtime. prism.vim will record this colorscheme (in g:prism_config_file, defaults to ~/.prism.vim.json), and use it in the future, for current working directory

" use current colorscheme
:PrismSet<enter>
" select from installed colorschemes
:PrismSet <tab>

cd/lcd

prism.vim listens to the DirChanged event, there are four options that can be attached to:

  		"window" to trigger on `:lcd`
  		"global" to trigger on `:cd`
  		"auto"   to trigger on 'autochdir'.
  		"drop"	 to trigger on editing a file

See :h DirChanged

let g:prism_dir_changed_pattern = ['window', 'global']

Also see :h DirChanged for the patterns your Vim supports.

Tabs

Enable prism.vim on switching tabs by:

" defaults to 0, disabled
let g:prism_count_tab = 1

Then prism.vim adds tab index to count the value for picking colorscheme, and listens to TabEnter. Now switching tabs will change the colorscheme.
