Request: Custom callback function

[svermeulen]

In some cases it would be useful to be able to notify other plugins when the build is finished. It would be great if you could set a custom callback function along with the arguments passed to start()

[tpope]

Dispatch fires a QuickFixCmdPost cgetfile event each time a build finishes, with 'makeprg' and 'errorformat' set appropriately. Need anything else?

[svermeulen]

I didn't consider that. That still doesn't quite work though because that autocommand doesn't appear to be run when the 'background' parameter is set to 1 (and this is the common scenario in my case).

[tpope]

There is no background event, as it's impossible to reliably produce one.

[svermeulen]

Right now I just have some calls added to dispatch#complete which works fine for me. At some point though I'd like to share out the code that depends on that, and in that case I'd need some other way to hook into that. So I was thinking it might be possible to have a callback function there, attached to the request object? If not I can live with that.

[svermeulen]

I'd make a pull request for it if you think it might be something you'd merge?

[tpope]

That doesn't fire for all background builds. Notably, it doesn't work for tmux. I don't want to expose an API that only works some of the time.

Ah I see. No problem.
