Automatically activate fa-show #12

Hi abo,

Is it possible to make fa-show run when point enter a function call (a pair of parentheses) and fa-abort when point exits the function call? I think this is really convenient.

abo-abo commented 10 years ago

It's hardly possible in general, since it can make Emacs unresponsive: the call to fa-show can take some time depending on the size of source base, and the parsing out the current function is regex-based, so it's slow. Still I'd like to see how it looks like, so I'll try to implement this when I have some time.

Thanks you.

Have a look at fa-auto. It seems a bit annoying at the moment, but it might be useful.

tuhdo commented 10 years ago

Thanks! This feature is great. A few suggestions:

Once the popup appears, fa-auto should be disabled. Otherwise it will keep jumping back to the first interface.
Once point moves out of the closing parentheses, the popup should be automatically closed. Upon entering inside a pair of parentheses, the popup appears again.
