Question

make emacs semantic auto complete tip "always on"

Answer 1

+1 A:

Automatically starting inline completion in idle time
M-x global-semantic-idle-completions-mode
This is a minor mode which runs semantic-complete-analyze-inline-idle during idle time. Instead of trying to complete the symbol immediately, it will just display the possible completions, and underline the current symbol the cursor is on.

In practice this means that the possible completions will appear whenever you stop typing and the cursor is under a symbol where completions are possible.

To use it, just put

(global-semantic-idle-completions-mode)

to your .emacs after loading the CEDET.

I have already tried that. I actually invoke that mode from within emacs for now (using M-x). But with this mode active, the suggestion that would have been at the top of the tooltip, or the completions menu, is displayed on the line itself and no tooltip nor menuy is shown.

Using the inline completion myself, I didn't notive that this idle mode only uses inline completion, that's a pity. To the best of my knowledge, the current CEDET does not have functionality you want.

To change the completion style, you need to customize the variable semantic-complete-inline-analyzer-idle-displayor-class, and choose one of the other displayor types.Many folks found the popup annoying, so an alternate default was presented.
