coc_current_function for arrow functions

[ellioseven]

I'm trying to get the current function to show on lightline, which seems to work for normal functions, but not arrow functions:

// coc_current_function: ""
const foo = () => {
  return "foo"
}

// coc_current_function: "bar"
function bar () {
  return "bar"
}

Is there some kind of configuration I'm missing?

Here is my function:

function! CocCurrentFunction()
  return get(b:, 'coc_current_function', '')
endfunction

It's expect since we only know foo is const

So this seems to be a response from ts-server that isn't providing the correct kind. This is an upstream issue then?

It's expected, IMO.
