Exuberant Ctags is a multilanguage reimplementation of the much-underused ctags(1) program and is intended to be the mother of all ctags programs. It generates indexes of source code definitions which are used by a number of editors and tools. The motivation which drove the development of Exuberant Ctags was the need for a ctags program which supported generation of tags for all possible C language constructs (which no other ctags offers), and because most were easily fooled by a number of preprocessor contructs.
Exuberant Ctags offers the following features:
It supports the following languages: Assembler, AWK, ASP, BETA, Bourne/Korn/Z Shell, C, C++, C#, COBOL, Eiffel, Erlang, Fortran, Java, Lisp, Lua, Makefile, Pascal, Perl, PHP, PL/SQL, Python, REXX, Ruby, Scheme, S-Lang, SML (Standard ML), Tcl, Vera, Verilog, VHDL, Vim, and YACC.
It is capable of generating tags for virtually all C language constructs.
It is very robust in parsing code. In particular, the C/C++ parser is far less easily fooled by code containing #if preprocessor conditional constructs, using a conditional path selection algorithm to resolve complicated situations, and a fall-back algorithm when this one fails.
Supports output of Emacs-style TAGS files (i.e. "etags").
User-defined languages, using Posix regular expressions.
Supports UNIX, MSDOS, Windows 95/98/NT/2000/XP, OS/2, QNX, Amiga, QDOS, RISC OS, VMS, Macintosh, and Cray. Some pre-compiled binaries are available on the web site.

Which brings us to the most obvious 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 (firstname.lastname@example.org) 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.
