       ocamllex - The OCaml lexer generator


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


       The  ocamllex(1)  command  generates  OCaml  lexers from a set of regular expressions with
       associated semantic actions, in the style of lex(1).

       Running ocamllex(1) on the input file lexer.mll produces OCaml 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  ocamlyacc(1),  the  semantic  actions
       compute a value belonging to the type token defined by the generated parsing module.


       The ocamllex(1) command recognizes the following options:

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

       -o output-file
              Specify  the  name  of the output file produced by ocamllex(1).  The default is the
              input file name, with its extension replaced by .ml.

       -q     Quiet mode.   ocamllex(1)  normally  outputs  informational  messages  to  standard
              output.  They are suppressed if option -q is used.

       -v or -version
              Print version string and exit.

       -vnum  Print short version number and exit.

       -help or --help
              Display a short usage summary and exit.
