| ### DEPENDENCIES ### |
| |
| Prerequisites: |
| * Java JRE 1.6 or greater. |
| * Apache Ant 1.7.0 or greater; see http://ant.apache.org/manual/install.html |
| |
| Before building the JavaScript target you will need to download a few third |
| party open source libraries: |
| |
| * ant-contrib: Download ant-contrib here: http://downloads.sourceforge.net/ant-contrib/ant-contrib-1.0b3-bin.zip?modtime=1162486738&big_mirror=0 |
| * Unzip the downloaded file. |
| * Move ant-contrib-1.0b3.jar from the unzipped directory to runtime/JavaScript/third/ |
| |
| * closure compiler: Download here: http://closure-compiler.googlecode.com/files/compiler-latest.zip |
| * Unzip the downloaded file. |
| * Move compiler.jar from the unzipped directory to runtime/JavaScript/third/ |
| |
| * jsdoc-toolkit: Download the latest release from here: http://code.google.com/p/jsdoc-toolkit/downloads/list |
| * Unzip the downloaded file. |
| * Move the unzipped folder to runtime/JavaScript/third/jsdoc-toolkit |
| |
| * jsunit: Download here: https://sourceforge.net/project/showfiles.php?group_id=28041&package_id=19823&release_id=404277 |
| * Unzip the downloaded file. |
| * Move the unzipped folder to runtime/JavaScript/tests/jsunit |
| |
| ### BUILD ### |
| 1) In a shell cd to runtime/JavaScript/build. |
| 2) Run 'ant'. This will build the JavaScript runtime libraries into the |
| runtime/JavaScript/lib folder. |
| |
| ### TESTS ### |
| Compile Tests: |
| 1) Build the Antlr tool itself (see main Antlr documentation for details). |
| This is most easily done by cd'ing to the root of the antlr code and running |
| 'mvn -Dmaven.test.skip=true package assembly:assembly'. If using a |
| different build method, update runtime/JavaScript/build/antlr3.properties to |
| point to the alternative jar. |
| 2) In a shell cd to runtime/JavaScript/build. |
| 3) Run 'ant compile-tests'. This can take a while. Warnings (but not errors) |
| issued during this step are expected. (We test the JS runtime against |
| grammars that have recoverable problems.) |
| |
| Run Tests: |
| 1) Compile the tests using the directions above. |
| 2) Open runtime/JavaScript/tests/jsunit/testRunner.html in a browser. Note |
| that some browsers (notably, Firefox 3.5) will have trouble with this page |
| when opened with the 'file://' protocol. To circumvent this issue, start |
| and access the page through a lightweight http server (e.g. Mongoose). |
| 3) Select the file runtime/JavaScript/tests/functional/all.html (or any other |
| test html file). |
| 4) Hit 'Run' and (hopefully ;) watch the pretty green bar grow. |
