ac-helm cannot complete the first time

[tuhdo]

I cannot use ac-complete-with-helm the first time because of this error:

helm-show-completion: Wrong type argument: overlayp, nil [5 times]

I had to run auto-complete first to "activate" ac-helm. After executing initial auto-complete, calling ac-complete-with-helm produces no more errors. But I had to execute auto-complete first.

@tuhdo Thank you for your bug report, and Sorry for insufficient solution on #2. :-)

@yasuyk Thanks. Work great.

I am using ac-complete for some languages (lisp, Java, C/C++). However, in C/C++, there's a package called auto-complete-clang that get candidates from clang compiler. I prefer this package to normal ac-complete + cedet, because auto-complete-clang gives more information for a symbol i.e. a complete function signature with its argument information and its return type, compare to cedet only gives a list of candidates. Later auto-complete-clang allows you to replace the argument list in its signature one by one.

Currently, ac-helm works by activating auto-complete-clang first, then execute ac-complete-with-helm. Is there a way to make auto-complete-clang use ac-helm interface?

[tuhdo]

Anyway, I think even if you implement it so that ac-helm can list candidates from auto-complete-clang, it still cannot provide full function signature after candidate selection. I will still use the normal ac-complete interface for auto-complete-clang, since it provides such feature.

auto-complete-clang is a great elisp package. It parses function signature, and expands parameter by yasnippet, so auto-complete-clang do complicated task. However ac-helm is tiny package, and it is aimed at supporting to narrow a lot of auto-complete candidates by helm. What you say is beyond the duty of ac-helm. I think what you need is a specialized helm interface for clang.

[tuhdo]

Yes, I know. And except for C/C++, I use ac-helm for everything else that executes auto-complete command (elisp, java, shell etc...).
