Any option for Outline? about coc-denite HOT 5 CLOSED

PR welcome

Yes, I'm trying to implement it.

From what I see, outline is a bit tricker than symbols, since it invoke a call to ctags and some other processing. And it seems like, there's no way to connect to coc.nvim's Outline function, so, we have to reimplement it in here.

Is that the right approach, or I'm missing something? what do you think @chemzqm ?

There is languages.getDocumentSymbol function exposed, but I think you can just use denite's outline source.

Ah, ok. My bad, I tried denite's outline but wasn't happy with it (the default setting) because it required to have a tags file generated at first. Coc.nvim generate the tags on the fly just for the selected file.

I copied the ctags option of coc.nvim and now it seems to works.

For those who come to this ticket in the future, as chemzqm said, we can just use Denite's outline source, with a bit modification:

call denite#custom#var('outline', 'command', ['ctags'])
call denite#custom#var('outline', 'options', ['-f -', '--excmd=number'])

The -f - option tells ctags to output the result to stdout instead of a tag file, so Denite can pick it up.

Thank you so much @chemzqm !
