|
---|
| 12 | <h3>Description</h3>
|
---|
| 13 | <p>
|
---|
| 14 | Invokes the <a HREF="http://javacc.dev.java.net/" target="_top">JavaCC</a> compiler
|
---|
| 15 | compiler on a grammar file.
|
---|
| 16 | </p>
|
---|
| 17 | <p>
|
---|
| 18 | To use the javacc task, set the <i>target</i> attribute to the name of the
|
---|
| 19 | grammar file to process. You also need to specify the directory containing
|
---|
| 20 | the JavaCC installation using the <i>javacchome</i> attribute, so that ant
|
---|
| 21 | can find the JavaCC classes. Optionally, you can also set the
|
---|
| 22 | <i>outputdirectory</i> to write the generated file to a specific directory.
|
---|
| 23 | Otherwise javacc writes the generated files to the directory containing
|
---|
| 24 | the grammar file.
|
---|
| 25 | </p>
|
---|
| 26 | <p>
|
---|
| 27 | This task only invokes JavaCC if the grammar file is newer than the generated
|
---|
| 28 | Java files. javacc assumes that the Java class name of the generated parser
|
---|
| 29 | is the same as the name of the grammar file, ignoring the .jj.
|
---|
| 30 | If this is not the case, the javacc task will still work, but it will always
|
---|
| 31 | generate the output files.
|
---|
| 32 | </p>
