It seems xcscope lacks tag completion feature. Any plans to implement it?

I don't know what this is. Does ggtags support it?

[EgorDuplensky]

Yes, it does.
This is similar to helm/ivy/ido behavior, for example, when you start a command with 'M-x' they suggest completions.
ggtags-find-definition basically does the same but just for tags.

I just looked at it, and I don't see anything in the cscope tool to report which symbols the database knows about. Manpage: http://cscope.sourceforge.net/cscope_man_page.html

You can search for . and then parse the output in some way, but that would take a lot of work to make reliable. I don't think this is worth the effort, so I'm not going to work on that, but if you want to send me patches, we can talk about it :)
