<h3>Description</h3>

|
<p>

2001-02-13 12:32:01 +00:00
|
|
|
Invokes the <a HREF="http://www.antlr.org/" target="_top">ANTLR</a> Translator generator
|
2000-11-14 09:30:38 +00:00
|
|
|
on a grammar file.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
To use the ANTLR task, set the <i>target</i> attribute to the name of the
|
|
|
|
|
grammar file to process. Optionally, you can also set the
|
|
|
|
|
<i>outputdirectory</i> to write the generated file to a specific directory.
|
|
|
|
|
Otherwise ANTLR writes the generated files to the directory containing
|
|
|
|
|
the grammar file.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
This task only invokes ANTLR if the grammar file is newer than the generated
|
|
|
|
|
files.

<h3>Example</h3>
|
|
|
|
|
<blockquote><pre>
|
|
|
|
|
<antlr
|
|
|
|
|
target="etc/java.g"
|
|
|
|
|
outputdirectory="build/src"
|
|
|
|
|
/>
|
|
|
|
|
</pre></blockquote>
|
|
|
|
|
<p>
|
|
|
|
|
This invokes ANTLR on grammar file etc/java.g, writing the generated
|
|
|
|
|
files to build/src.
