      1 ### DEPENDENCIES ###
      2 
      3 Prerequisites:
      4   * Java JRE 1.6 or greater.
      5   * Apache Ant 1.7.0 or greater; see http://ant.apache.org/manual/install.html
      6 
      7 Before building the JavaScript target you will need to download a few third
      8 party open source libraries:
      9 
     10   * ant-contrib: Download ant-contrib here: http://downloads.sourceforge.net/ant-contrib/ant-contrib-1.0b3-bin.zip?modtime=1162486738&big_mirror=0
     11   * Unzip the downloaded file.
     12   * Move ant-contrib-1.0b3.jar from the unzipped directory to runtime/JavaScript/third/
     13 
     14   * closure compiler: Download here: http://closure-compiler.googlecode.com/files/compiler-latest.zip
     15   * Unzip the downloaded file.
     16   * Move compiler.jar from the unzipped directory to runtime/JavaScript/third/
     17 
     18   * jsdoc-toolkit: Download the latest release from here: http://code.google.com/p/jsdoc-toolkit/downloads/list
     19   * Unzip the downloaded file.
     20   * Move the unzipped folder to runtime/JavaScript/third/jsdoc-toolkit
     21 
     22   * jsunit: Download here: https://sourceforge.net/project/showfiles.php?group_id=28041&package_id=19823&release_id=404277 
     23   * Unzip the downloaded file.
     24   * Move the unzipped folder to runtime/JavaScript/tests/jsunit
     25 
     26 ### BUILD ###
     27 1) In a shell cd to runtime/JavaScript/build.
     28 2) Run 'ant'. This will build the JavaScript runtime libraries into the
     29    runtime/JavaScript/lib folder.
     30 
     31 ### TESTS ###
     32 Compile Tests:
     33 1) Build the Antlr tool itself (see main Antlr documentation for details).
     34    This is most easily done by cd'ing to the root of the antlr code and running
     35    'mvn -Dmaven.test.skip=true package assembly:assembly'.  If using a
     36    different build method, update runtime/JavaScript/build/antlr3.properties to
     37    point to the alternative jar.
     38 2) In a shell cd to runtime/JavaScript/build.
     39 3) Run 'ant compile-tests'.  This can take a while.  Warnings (but not errors)
     40    issued during this step are expected.  (We test the JS runtime against
     41    grammars that have recoverable problems.)
     42 
     43 Run Tests:
     44 1) Compile the tests using the directions above.
     45 2) Open runtime/JavaScript/tests/jsunit/testRunner.html in a browser.  Note
     46    that some browsers (notably, Firefox 3.5) will have trouble with this page
     47    when opened with the 'file://' protocol.  To circumvent this issue, start
     48    and access the page through a lightweight http server (e.g. Mongoose).
     49 3) Select the file runtime/JavaScript/tests/functional/all.html (or any other
     50    test html file).
     51 4) Hit 'Run' and (hopefully ;) watch the pretty green bar grow.
