NAME

       ml-ulex - lexer generator for Standard ML

SYNOPSIS

       ml-ulex [--dot] [--dump] [--match] [--ml-lex-mode] [--minimize] file

DESCRIPTION

       This manual page documents briefly the ml-ulex command.	This manual page was written for the Debian distribution because the original pro-
       gram does not have a manual page.  The ml-ulex script is part of the SML/NJ CM (Compilation and Library Manager) that is used  to  generate
       standalone programs.

OPTIONS

       A summary of some of the options is included below.

       --dot  Generate DOT output (for graphviz).

       --match
	      Enter interactive matching mode.

       --ml-lex-mode
	      Operate in ml-lex compatibility mode.

SEE ALSO

       The  programs  are  documented fully by CM: The SML/NJ Compilation and Library Manager, User Manual, Matthias Blume, which is available via

Name
       lex - generate lexical analyzer

Syntax
       lex [-tvfn] file...

Description
       The  command  generates	programs  to be used in simple lexical analysis of text.  The input files (standard input default) contain regular
       expressions to be searched for, and actions written in C to be executed when expressions are found.

       A C source program, 'lex.yy.c', is generated.  It is compiled using the following command line:
       cc lex.yy.c -ll
       This program copies unrecognized portions of the input to the output, and executes the associated C action for each regular expression that
       is recognized.

Options
       -f   Runs a faster compilation (does not pack resulting tables).  This is limited to small programs.

       -n   Prints no summary information (default option).

       -t   Writes to standard output instead of to file

       -v   Prints one-line summary of generated statistics.

Examples
       In the following example, the command
       lex lexcommands
       draws instructions from the file lexcommands, and places the output in lex.yy.c.  The command
       %%
       [A-Z]	 putchar(yytext[0]+'a'-'A');
       [ ]+$
       [ ]+ putchar(' ');

       is  an example of a program that would be put into a command file.  This program converts upper case to lower, removes blanks at the end of
       lines, and replaces multiple blanks by single blanks.
