Xref-ing non used symbols

Xref-ing non used symbols

[William Gacquer]

Hello
	I would like to retrieve all symbols (especialy C functions) that
are not used at all using the cross referencer. But I did not find the way
to do that. Is this feasible? How?
	Regards,
	William

Take a look at some of the example Tcl scripts for examples.  There is one
that finds unused global variables in: 

  snavigator/sdk/api/tcl/database/examples/unused.tcl

   hyper requires some environment, too---the script snavigator show what
   it needs.  Here's a suitable "hyper" script (hacked from snavigator)
   which you could put (after changing /usr/local/sn to whatever you
   used) suitably earlier in your path:

A lot of this confusion would be solved if the S-N extensions for Tcl were a
loadable module.  Then these scripts could "require" the hyper package.

It's currently not done this way.  This is something strange. :-)

That explains it.  You must use hyper, not wish.  (The script I just
sent may be convenient.)  With the script, I just did the following,
and it worked:

/usr/local/sn/share/sdk/api/tcl/database/examples/unused.tcl /snprj/zsh zsh

My project is located in /home/wgacquer/Project
A ".snprj" directory is in /home/wgacquer/Project
A "Project.proj" file is in /home/wgacquer/Project

thus I tried :

export PATH=/usr/local/snavigator/bin:$PATH
wish unused.tcl /home/wgacquer/Project Project
wish unused.tcl /home/wgacquer/Project Project.proj
wish unused.tcl /home/wgacquer/Project /home/wgacquer/Project/Project.proj

 but definitely, it does not work.

It's a Tcl command, defined by the libraries included in the SN Tcl
interpreter "hyper".  How exactly did you run unused.tcl?

Thanks Ben
	I have tried that but I got the following error message :
Error in startup script: invalid command name "dbopen"

	In fact, "man dbopen" refers to a command called dbopen but I was
not able to find it on my linux system, even in the source navigator tree.

	Any idea?
