And now my cursor is somewhere in main function and I want to jump to beta::b

When I print possibilities:

it is something like:
beta::b
class:beta access:public
int b;
So :ts properly is showing the jump location but for some reason calling it via:
:ta beta::b
gives me wrong result.
All this problem happns only if I have two or more classes definition in the
same file. If they are spread around diffrent files then it is all fine.
I generated tags from your file using the ctags command you gave, and I can
reproduce the problem.
I also see the cause.
With the options you give, the tag file entries for alpha::b and beta::b both
have the same search pattern. Here are their entries:
alpha::b .\test.cpp /^ int b;$/;" m class:alpha
file: access:private
beta::b .\test.cpp /^ int b;$/;" m class:beta file:
access:public
I'm not sure whether this can be fixed.
I know the tagbar plugin ( http://www.vim.org/scripts/script.php?script_id=3465
) can correctly jump to each tag, but I don't know how this is accomplished.
You could look into the plugin or contact the author.
Certainly, you could also post-process your tags file to modify the search
pattern. This may be how tagbar does it, I do not know.
If I manually edit the generated tags file to include a search for the class
before a search for the tag itself, I can correctly jump to beta::b and
alpha::b with the :tag command:
alpha::b .\test.cpp /class alpha/;/^ int b;$/;" m
class:alpha file: access:private
beta::b .\test.cpp /class beta/;/^ int b;$/;" m class:beta
file: access:public
Note my introduction of /class alpha/; and /class beta/; to perform a double
search in each case.
This could certainly be automated, since the class name is right in the tag
definition. I'll leave that to you.
Adding the "-n" flag will fix this, at the price that: if you insert a
new line somewhere into your file, the line numbers will also change,
thereby silently invalidating the tags file.
I suggest putting comments on the two identical lines that differentiate
them.
