Exuberant Ctags
===============
Author: Darren Hiebert ([e-mail], http://darren.hiebert.com)

This is a reimplementation of the much underused ctags(1) program and is
intended to be the mother of all ctags programs. I was motivated to write this
because no currently available ctags program supported generation of tags for
all possible tag candidates, and because most were easily fooled by a number
of contructs. I am quite pleased with it, and others who have used it have
been very enthusiastic about the greater reliability and functionality it
provides.


What makes this ctags desirable?

1.  Supports C, C++, and Java code.

2.  It is capable of generating tags for *all* types of language tags,
    including all of the following:

        class names
        macro definitions
        enumeration names
        enumerators
        function (method) definitions
        function (method) prototypes/declarations
        interface names (Java)
        class, interface, struct, and union data members
        structure names
        typedefs
        union names
        variables (definitions and external declarations)

3.  It is very robust in parsing code and is far less easily fooled by code
    containing #if preprocessor conditional constructs, using a conditional
    path selection algorithm to resolve complicated choices, and a fall-back
    algorithm when this one fails.

4.  Can also be used to print out a human-readable list of selected objects
    found in source files.

5.  Supports output of Emacs-style TAGS files ("etags").

6.  Supports UNIX, QNX, MSDOS, Windows 95/NT, OS/2, Amiga, and VMS.
    Some pre-compiled binaries are available on the web site.


You can find Exuberant Ctags at the following locations:

    http://darren.hiebert.com/ctags/         (Official web site)
    ftp://ftp.revnet.com/pub/ctags/
    ftp://sunsite.unc.edu/pub/Linux/devel/lang/c/


Which brings us to the most frequently asked question:

  Q: Why is it called "Exuberant" ctags?
  A: Because one of the meanings of the word is:

     exuberant : produced in extreme abundance : PLENTIFUL syn see PROFUSE

Compare the tag file produced by Exuberant Ctags with that produced by any
other ctags and you will see how appropriate the name is.

Exuberant Ctags was originally derived from and inspired by the ctags program
by Steve Kirkendall ([e-mail]) that comes with the Elvis vi clone
(though almost none of the original code remains). This, too, is freely
available.

Please report any problems you find. The two problems I expect to be most
likely are either a tag which you expected but is missing, or a tag created
in error (shouldn't really be a tag). Please include a sample of code (the
definition) for the object which misbehaves.
