As of this writing, the following command-line options are supported:
<ul>
<li><b>-b</b>
Show only the basis for each parser state in the report file.
<li><b>-c</b>
Do not compress the generated action tables.  The parser will be a
little larger and slower, but it will detect syntax errors sooner.



<li><b>-D<i>name</i></b>
Define C preprocessor macro <i>name</i>.  This macro is usable by
"<tt><a href='#pifdef'>%ifdef</a></tt>" and
"<tt><a href='#pifdef'>%ifndef</a></tt>" lines
in the grammar file.
<li><b>-g</b>
Do not generate a parser.  Instead write the input grammar to standard
................................................................................
</pre></p>

<p>Then the Parse() function generated will have an 4th parameter
of type "MyStruct*" and all action routines will have access to
a variable named "pAbc" that is the value of the 4th parameter
in the most recent call to Parse().</p>

























<a name='pfallback'></a>
<h4>The <tt>%fallback</tt> directive</h4>

<p>The <tt>%fallback</tt> directive specifies an alternative meaning for one
or more tokens.  The alternative meaning is tried if the original token
would have generated a syntax error.</p>

<li><b>-c</b>

<p>The <tt>%extra_context</tt> directive works the same except that it

on Parse().

<a name='extractx'></a>
<h4>The <tt>%extra_context</tt> directive</h4>

The <tt>%extra_context</tt> directive instructs Lemon to add a 2th parameter
to the parameter list of the ParseAlloc() and ParseInif() functions.  Lemon
doesn't do anything itself with these extra argument, but it does
store the value make it available to C-code action routines, destructors,
and so forth.  For example, if the grammar file contains:</p>

<p><pre>
    %extra_context { MyStruct *pAbc }
</pre></p>

<p>Then the ParseAlloc() and ParseInit() functions will have an 2th parameter
of type "MyStruct*" and all action routines will have access to
a variable named "pAbc" that is the value of that 2th parameter.</p>

<p>The <tt>%extra_argument</tt> directive works the same except that it
is passed in on the Parse() routine instead of on ParseAlloc()/ParseInit().
