NAME

       jocamllex - The JoCaml lexer generator

SYNOPSIS

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

DESCRIPTION

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

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

       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, Lex-
       ing.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.

OPTIONS

       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.
