ml-ulex1

Usage

Overview

ML-Ulex is a lexer generator that supports Unicode characters (in UTF-8 representation) and an extended form of regular expressions.

Options

-32

run the 32-bit version of the program (currently the default).

-64

run the 64-bit version of the program. This option only applies to the x86-64 (aka amd64) architecture.

--dot

generate DOT output ( <http://www.graphviz.org>). The generated file will be named file.dot, where file is the input file.

--match

enter interactive matching mode. This will allow interactive testing of the machine; presently, only the INITIAL start state is available for testing (see the User Guide <http://www.smlnj.org/doc/ml-lpt/manual.pdf> for details on start states).

--ml-lex-mode

operate in ml-lex compatibility mode.

--table-based

generate a table-based lexer.

--fn-based

generate a lexer that represents states as functions and transitions as tail calls.

--minimize

generate a minimal machine. Note that this is slow, and is almost never necessary.

--strict-sml

generate strict SML (i.e., do not use SML/NJ extensions). This flag is useful if you want to use the output with a different SML system.
