[Message part 1 (text/plain, inline)]

Run "etags" of emacs 23.1 on the attached "Foo.H" file . 

 

The resulting TAGS file indicates "Foo.H" is empty.

 

Seems to me it should show two definitions for the 2 specializations of
`Worker`. 

 

----------- TAGS --------------
^L

Foo.H,0

----------------------------------

 

----------- Foo.H ----------------

template<

  class _A,

  class _B = Select<_A>::Result

  >

class Worker;

 

 

template<class _A>

class Worker<_A,int>

{

};

 

template<class _A>

class Worker<_A,double>

{

};

---------------------------------------

[Message part 2 (text/html, inline)]

[Foo.H (text/plain, attachment)]

(I'm going through old bug reports that unfortunately got no response at
the time.)

I don't know whether it should or not, but the behaviour of etags in
Emacs 28 is still the same -- it produces an empty TAGS file.

'etags's support for templates is very rudimentary, it doesn't
currently identify a class if its name is followed by <foo,bar>.
Patches welcome.
