g:airline_statusline_funcrefs not defined in ftpugin/haxe.vim

[rahil627]

i know this is old and unmaintained, but...

if anyone runs into this problem with the airline plugin:
something like “g:airline_statusline_funcrefs” not defined during a call

i added this to my config file:
let g:airline_statusline_funcrefs = get(g:, 'airline_statusline_funcrefs', [])

i simply stole that from https://github.com/vim-airline/vim-airline/blob/master/autoload/airline.vim

but be warned, ive only used vim for a few days, so i have no idea what i’m doing :) :)
