<title>Exuberant Ctags: Why?</title>
</head>
<body>
<h1>What makes this implementation of ctags desirable?</h1>
<ol>
<p>
<li>
Supports <a href="languages.html">many programming languages</a>.
</li>
</p>
<p>
<li>It is capable of generating tags for <strong><em>all</em></strong> types
of C/C++ language tags, including all of the following:
<p>
<menu>
<li type=disk>class names
<li type=disk>macro definitions
<li type=disk>enumeration names
<li type=disk>enumerators
<li type=disk>function definitions
<li type=disk>function prototypes/declarations
<li type=disk>class, interface, struct, and union data members
<li type=disk>structure names
<li type=disk>typedefs
<li type=disk>union names
<li type=disk>variables (definitions and external declarations)
</menu>
</li>
</p>
<p>
<li>It is far less easily fooled by C code containing <code>#if</code>
preprocessor conditional constructs, using a conditional path selection
algorithm to resolve complicated choices, and a fall-back algorithm when
this one fails.
</li>
</p>
<p>
<li>Supports user-defined languages, using regular expressions.
</li>
</p>
<p>
<li>Supports output of Emacs-style TAGS files.
</li>
</p>
<p>
<li>Can also be used to print out a list of selected objects found in source
files.
</li>
</p>
<p>
<li>Compiles on UNIX, MSDOS, Windows 95/98/NT, OS/2, QNX, Amiga, QDOS, VMS,
Macintosh, and Cray.
</li>
</p>
</ol>
