| <h2> |
| <a NAME="jjtree"></a>JJDoc</h2> |
| <p><em>Since Ant 1.6</em></p> |
| <h3>Description</h3> |
| |
| <p>Invokes the <a href="http://javacc.dev.java.net/">JJDoc</a> preprocessor |
| for the JavaCC compiler compiler. It takes a JavaCC parser specification |
| and produces documentation for the BNF grammar. |
| It can operate in three modes, determined by command line options. |
| <p>To use the jjdoc task, set the <i>target</i> attribute to the name |
| of the JavaCC grammar file to process. You also need to specify the directory |
| containing the JavaCC installation using the <i>javacchome</i> attribute, |
| so that ant can find the JavaCC classes. Optionally, you can also set the |
| <i>outputfile</i> to write the generated BNF documentation file to a specific (directory and) file. |
| Otherwise jjdoc writes the generated BNF documentation file as the JavaCC |
| grammar file with a suffix .txt or .html.</p> |
| <p>This task only invokes JJDoc if the grammar file is newer than the |
| generated BNF documentation file.</p> |

| <table BORDER CELLSPACING=0 CELLPADDING=2 > |
| <tr> |
| <td VALIGN=TOP><b>Attribute</b></td> |
| |
| <td VALIGN=TOP><b>Description</b></td> |
| |
| <td ALIGN=CENTER VALIGN=TOP><b>Required</b></td> |
| </tr> |
| |
| <tr> |
| <td VALIGN=TOP>target</td> |
| |
| <td VALIGN=TOP>The javacc grammar file to process.</td> |
| |
| <td ALIGN=CENTER VALIGN=TOP>Yes</td> |
| </tr> |
| |
| <tr> |
| <td VALIGN=TOP>javacchome</td> |
| |
| <td VALIGN=TOP>The directory containing the JavaCC distribution.</td> |
| |
| <td ALIGN=CENTER VALIGN=TOP>Yes</td> |
| </tr> |
| |
| <tr> |
| <td VALIGN=TOP>outputfile</td> |
| |
| <td VALIGN=TOP>The file to write the generated BNF documentation file to. If not set, |
| the file is written with the same name as the JavaCC grammar file but with a the suffix .html or .txt. </td> |
| |
| <td ALIGN=CENTER VALIGN=TOP>No</td> |
| </tr> |
| |
| <tr> |
| <td VALIGN=TOP>text</td> |
| |
| <td VALIGN=TOP>Sets the TEXT BNF documentation option. This is a boolean |
| option.</td> |
| |
| <td ALIGN=CENTER VALIGN=TOP>No</td> |
| </tr> |
| |
| <tr> |
| <td VALIGN=TOP>onetable</td> |
| |
| <td VALIGN=TOP>Sets the ONE_TABLE BNF documentation option. This is a boolean option.</td> |
| |
| <td ALIGN=CENTER VALIGN=TOP>No</td> |
| </tr> |

| <h3> |
| Example</h3> |
| |
| <blockquote> |
| <pre><jjdoc |
| target="src/Parser.jj" |
| outputfile="doc/ParserBNF.html" |
| javacchome="c:/program files/JavaCC" |
| /></pre> |
| </blockquote> |
| This invokes JJDoc on grammar file src/Parser.jj, writing the generated |
| BNF documentation file, ParserBNF.html, file to doc. |
