Description: Lexical analyzer generator for Tcl
 tcLex is a lexer (lexical analyzer) generator extension to Tcl. It is
 inspired by Unix and GNU lex and flex, which are "tools for
 generating programs that perform pattern-matching on text". tcLex is
 very similar to these programs, except it uses Tcl philosophy and
 syntax, whereas the others use their own syntax and are used in
 conjunction with the C language. People used to lex or flex should
 then feel familiar with tcLex. tcLex is a small extension (the
 Windows compiled version is about 20kb, and the source is about
 150kb), because it extensively uses the Tcl library. However, the
 current doesn't use Tcl's regexp code anymore but a patched version
 is now included in tcLex, which makes it slightly bigger (by a few
 KB). tcLex should work with Tcl 8.0 and later.  tcLex will NEVER work
 with earlier versions, because it uses Tcl 8.0's "object" system for
 performance. The most interesting features are:
 .
  * cross-platform support, thanks to Tcl. Though it has been
    developed on Windows and tested on Windows and Unix only, it
    should work on other platforms as long as Tcl exists on these
    platforms. Supported Tcl platforms are Windows 95/NT, Unix (Linux,
    Solaris...) and Macintosh. Other platforms are VMS, OS/2,
    NeXTStep, Amiga...
 .
  * unlike lex and flex, which only generate static lexers written in
    C and intended to be compiled, tcLex dynamically generates Tcl
    commands that can be used like other C commands or Tcl procedures
    from within Tcl scripts or C programs.
 .
  * it uses Tcl regular expressions. That means you don't have to
    learn another regexp language.
 .
  * it works with Tcl namespaces
 .
  * the generated lexer commands can be used in one pass or
    incrementally, because they maintain state information. That way,
    several instances of the same lexer (eg a HTML parser) can run at
    the same time in distinct call frames and maintain distinct states
    (local variables...). Lexer need not be specially designed in
    order to be used incrementally, the same lexer can transparently
    be used in one pass or incrementally. This feature is especially
    useful when processing text from a file or an Internet socket (Web
    pages for example), when data is not necessarily available at the
    beginning of the processing.
