Re: why are "references" restricted to symbols for which we have definitions?

[Gautam Thaker]

Thanks Shigio.

So

global -s 

works well and gives me all the symbols, but I get too much output as every single variable , typename etc all get printed. I wish it were possible to restrict to symbols that are function/method calls.

(One nice thing about universal ctags is it shows the "kind" of entry a tags line is (eg, macro, function, etc.) I can then restrict a tag search to entries of a certain kind, a very useful thing at times .

Hello,
How about the following command?

$ global -xrs '.*'

-r, --reference
        Print  reference tags.  Reference means the reference to a symbol which
        has definitions.
-s, --symbol
        Print other symbol tags.  Other symbol means the reference to
a symbol which
        has no definition.
