C ++ function signature signature in Emacs?

Question

Can emacs be allowed to display function signatures and overload candidates when entering a function name and parameter list? It will be very helpful.

Answer 1

This can be done using CEDET (built-in) along with function-args :

Some functions:

• fa-show shows inline function arguments that allow you to switch between overloads.
• fa-jump goes to the overloaded candidate (when there are a lot of them).
• moo-completesometimes gives the best completion and uses helm, which is an advantage for speed.
• moo-propose-virtualuses the helmsignature of a virtual function in an overloaded class for instant filling.
• moo-propose-override ( ).
