Customize Runner

As a fully customizable plugin, this plugin allows you specify how to run your task by adding new item to dictionary g:asyncrun_runner:

function! s:my_runner(opts)
    echo "run: " . a:opts.cmd
endfunction

let g:asyncrun_runner = get(g:, 'asyncrun_runner', {})
let g:asyncrun_runner.test = function('s:my_runner')

Then, you can change g:asynctasks_term_pos to "test", and when you are running your task, your runner function will be called. or add a "pos=test" filed in your task option, it will overshadow the global g:asynctasks_term_pos.

Don't forget set output=terminal in your task configuration.
