Completion triggered by dot displays too long prefix

[wasamasa]

Is this supposed to be expected behaviour? I'm used to just see method names if using dot completion, not the common prefix, too.

Pretty much. I think Bond prefers it that way: https://github.com/cldwalker/bond/blob/master/lib/bond/readline.rb#L4, and it's the most feature-rich completion method. (EDIT: ) Irb also returns better completions this way.

Of course, we could use two prefixes (one for company-mode, and another internal to inf-ruby completion logic), and convert the completions between the two, but I wonder if that's worth the trouble.

Are you sure this is not merely something that can be fixed on the visual level like by just displaying everything after the dot if the dot triggered the completion and leaving the prefix alone?

if the dot triggered the completion

In your example above, as likely as not, m triggered completion.

Doing what I mentioned above wouldn't be particularly hard, and it would be "on the visual level". There is a certain simplicity to just displaying what Bond or Irb return, though.

Actually, it is triggered after the dot, I merely narrowed the examples down by typing m.

That's one possible scenario, but not the only one, that would allow you to reach the state depicted on the screenshot. If you press C-g and then type m, completion should be triggered again.
