Re: [Ctags-devel] Q: not to generate tags for Perl subroutine declarations?

[<cta...@li...>]

Ctags generates tags for declaration when specifically requested. For  
example, in C/C++, you get tags for prototypes when using --c-kinds= 
+p; you get tags for external variable declarations when using --c- 
kinds=+x. However, neither of these are enabled by default.

Generating tags for declarations is useful when you are generating  
tags from include files when you do not have the source code (i.e. I  
will often generate a tag file for /usr/include with --c-kinds=+px),  
which lets me jump to the prototype for memcpy(), etc.
