|
---|
| 15 | Description</h3>
|
---|
| 16 | <p>Invokes the <a href="http://javacc.dev.java.net/">JJTree</a> preprocessor
|
---|
| 17 | for the JavaCC compiler compiler. It inserts parse tree building actions
|
---|
| 18 | at various places in the JavaCC source that it generates. The output of
|
---|
| 19 | JJTree is run through JavaCC to create the parser.
|
---|
| 20 | <p>To use the jjtree task, set the <i>target</i> attribute to the name
|
---|
| 21 | of the JJTree grammar file to process. You also need to specify the directory
|
---|
| 22 | containing the JavaCC installation using the <i>javacchome</i> attribute,
|
---|
| 23 | so that ant can find the JavaCC classes. Optionally, you can also set the
|
---|
| 24 | <i>outputdirectory</i>
|
---|
| 25 | to write the generated JavaCC grammar and node files to a specific directory.
|
---|
| 26 | Otherwise jjtree writes the generated JavaCC grammar and node files to the directory
|
---|
| 27 | containing the JJTree grammar file. As an extra option, you can also set the
|
---|
| 28 | <i>outputfile</i> to write the generated JavaCC grammar file to a specific (directory and) file.
|
---|
| 29 | Otherwise jjtree writes the generated JavaCC grammar file as the JJTree
|
---|
| 30 | grammar file with a suffix .jj.</p>
|
---|
| 31 | <p>This task only invokes JJTree if the grammar file is newer than the
|
---|
| 32 | generated JavaCC file.</p>

| 521 | <p>*) <u>Footnote</u>: When running JJTree with the Ant taskdesk <i>jjtree</i> the option <code>-OUTPUT_DIRECTORY</code> must always
|
---|
| 522 | be set, because the project's basedir and the ant working directory might differ. So even if you don't specify the jjtree taskdef
|
---|
| 523 | <i>outputdirectory</i> JJTree will be called with the <code>-OUTPUT_DIRECTORY</code> set to the project's basedirectory.
|
---|
| 524 | But when the <code>-OUTPUT_DIRECTORY</code> is set, the <code>-OUTPUT_FILE</code> setting is handled as if relative to this
|
---|
| 525 | <code>-OUTPUT_DIRECTORY</code>. Thus when the <code>-OUTPUT_FILE</code> is absolute or contains a drive letter we have a
|
---|
| 526 | problem.
|
---|
| 527 | Therefore absolute <i>outputfile</i>s (when the <i>outputdirectory</i> isn't specified) are made relative to the default directory.
|
---|
| 528 | And for this reason <i>outputfile</i>s that contain a drive letter can't be supported.</p>
|
---|
| 529 |
|
---|
| 530 | <p>By the way: specifying a drive letter in the <code>-OUTPUT_FILE</code> when the <code>-OUTPUT_DIRECTORY</code> is set, also
|
---|
| 531 | results in strange behavior when running JJTree from the command line.</p>
