Complete CTRL+X CTRL+O ?

[lazywei]

When I press CTRL+X CTRL+O in insert mode, there will pops a list of method I can use.

Can this be implemented in YCM? (i.e. don't need to press CTRL+X CTRL+O)

YCM won't do semantic completion on every keystroke because it's too slow (and largely unnecessary). The semantic engine is supposed to trigger on ., -> and similar characters after which a member method/variable is to be typed.

Also, the data you get on Ctrl-X Ctrl-O is coming from YCM as well, because it registers itself as the omnifunc.

as Ruby, when

"blahblah".

and press Ctrl+X, Ctrl+O, it will show methods I can use for string
but if I didn't press that key, YCM won't be triggered ..

it's weird because you said that . it the trigger character
do i miss something?

There's no semantic completion for Ruby yet.
