function! s:snowflake_after(...)
  execute ':QuickfixStatusEnable'
  execute ':HierUpdate'
endfunction

let g:snowflake_callbacks = {
  \ 'after_init': function('snowflake#flake8#run'),
  \ 'after_run': function('s:snowflake_after')
  \ }

autocmd BufWritePost *.py call snowflake#flake8#run()
autocmd InsertLeave *.py call snowflake#flake8#run()
autocmd TextChanged,TextChangedI *.py call snowflake#flake8#run()

• Execute right after source code open
• Show QuickFix error in statusline, and highlight QuickFix errors run quickfixstatus.vim and vim-hier.
