Idle Completions Mode

Semantic Idle Completions mode is a minor mode for performing code completions during idle time. The completions are displayed inline, with keybindings that allow you to cycle through different alternatives.

Semantic Idle Completions mode performs completion based on the Semantic Analyzer (see Analyzer).

If the tag at point has at least one completion, Semantic Idle Completions mode displays that completion inline—i.e., as part of the buffer text (you can change the display method by customizing semantic-complete-inline-analyzer-idle-displayor-class, as described below). The completed part is highlighted, to indicate that it is not yet properly inserted into the buffer. The echo area shows the completion, and whether there are other possible completions, like this:

     besselj [1 of 6 matches]

While the completion is being displayed, the following keybindings take effect:

<RET>

C-m

Accept the current completion (semantic-complete-inline-done), placing it in the buffer and moving point to the end of the completed tag.

M-n

Select the next possible completion (semantic-complete-inline-down). The new completion is shown inline, replacing the old completion.

M-p

Select the previous possible completion (semantic-complete-inline-up).

<TAB>

C-i

Accept as much of the completion as possible. If no additional completion can be accepted without ambiguity, select the next possible completion (semantic-complete-inline-TAB).

C-g

Quit without completing (semantic-complete-inline-quit).

You can also exit inline completion by issuing any other Emacs command. The completion text then disappears from the buffer.
