       jocamllex - The JoCaml lexer generator


       jocamllex [ -o output-file ] [ -ml ] filename.mll


       The  jocamllex(1) command generates Objective Caml lexers from a set of
       regular expressions with associated semantic actions, in the  style  of

       Running jocamllex(1) on the input file lexer.mll produces Caml code for
       a lexical analyzer in file

       This file defines one lexing function per  entry  point  in  the  lexer
       definition.  These  functions  have the same names as the entry points.
       Lexing functions take as  argument  a  lexer  buffer,  and  return  the
       semantic attribute of the corresponding entry point.

       Lexer  buffers  are  an  abstract data type implemented in the standard
       library   module    Lexing.    The    functions    Lexing.from_channel,
       Lexing.from_string  and  Lexing.from_function create lexer buffers that
       read from  an  input  channel,  a  character  string,  or  any  reading
       function, respectively.

       When  used in conjunction with a parser generated by jocamlyacc(1), the
       semantic actions compute a value belonging to the type token defined by
       the generated parsing module.


       The jocamllex(1) command recognizes the following options:

       -o output-file
              Specify  the output file name output-file instead of the default
              naming convention.

       -ml    Output code  that  does  not  use  the  Caml  built-in  automata
              interpreter.   Instead,   the   automaton  is  encoded  by  Caml
              functions.  This option is useful  for  debugging  jocamllex(1),
              using it for production lexers is not recommended.
