The initial checkin of antidote - the ant GUI.

This initial version is mainly to establish the source infrastructure. The code currently compiles under JDK 1.2+ and provides a basic GUI which is able to open a build.xml file. Stay tuned ...

  <BODY> 
    <H1>Ant GUI Feature List</H1>
    <P>Version 0.3 (2000/10/31)</P>
    <P>Authors: 
    <A HREF="mailto:simeon@fitch.net">Simeon H.K. Fitch</A>,
    <A HREF="mailto:chris@christophertodd.com">Chris Todd</A>,
    <A HREF="mailto:clint.combs@contrado.com">Clint Combs</A>,

    <A HREF="mailto:duncan@x180.com">James Duncan Davidson</A>
    <P>The purpose of this document is to capture the proposed feature list for
    the Ant Graphical User Interface. This is not a hard requirements
    specification; you won't find the word "shall" in it (other than that one
    time). :-)</P>
    <P>In general, the purpose of the GUI is to allow the quick generation and
    modification of Ant build files, helping the user define their build process
    and track down build problems. For it to be successful it must make the user
    more efficient and productive, insofar as their involvement in build
    management and use of Ant goes. It should first address the needs of the
    novice Ant user, and then add abilities for the "power" user. This does not
    imply that the UI should be "dumbed down", it just means that usability
    should come before slick but complicated features.</P>
    <P>The features are in a loose order of expressed interested by
    contributors.</P>
    <!-- Section List -->
    <OL TYPE="A">
      <LI><H2>Build Management</H2></LI>
      <P>Once a build file is created, the user will want to start and
      stop it from the UI. This will serve both as a testing facility as well as
      a general compile tool. Monitoring of the build can occur through the Ant
      BuildListener interface.</P>
      <OL>
        <LI>Build execution.</LI>
        <OL TYPE="a">
          <LI>Initiate a build starting from any task.</LI>
          <LI>Stop a currently active build.</LI>
        </OL>
        <LI>Build monitoring.</LI>
        <OL TYPE="a">
          <LI>Provide feedback on the current status of the build.<BR>
          <I>This is where you can have more fun with the directed graph view,
          where the current build activity is highlighted on the screen, making
          the whole thing behave like a dynamic state transition diagram. You
          can then highlight the node where the build fails, etc.</I></LI>
          <LI>Show log messages from the build, allowing the user to determine
          the task they originated from.</LI>
          <LI>Provide the ability to filter logged messages, adn to display the
          messages in color codes corresponding to logging levels.</LI>
          <LI>Allow the installation of custom log listeners</LI>
          <LI>Record runtime statistics to determine bottleneck in the build
          process<BR>
          <I>This may be of limited use, as calling &lt;javac&gt; probably takes
          the most time. But maybe not.</I></LI> 
        </OL>
      </OL>
      <BR>
      <LI><H2>Build Wizard (auto-configure)</H2></LI>
      <P>To make starting a new project with Ant as easy as possible, the a
      wizard type of UI can be used where the user provides some basic
      information and the application deduces what a default build.xml file for
      it should look like.</P>
      <OL>
        <LI>Project attributes.</LI>
        <OL TYPE="a">
          <LI>Provide input for the required project attributes.<BR>
          <I>This probably means project name and default target.</I></LI>
        </OL>
        <LI>Project directories.</LI>
        <OL TYPE="a">
          <LI>Ask for the source directory.</LI>
          <LI>Ask for the destination directory.</LI>
          <LI>Ask for the necessary JAR files.</LI>
        </OL>
        <LI>Project properties.</LI>
        <OL TYPE="a">
          <LI>Provide a default set of project properties.<BR>
          <I>In here would be things like classpath, build.compiler, version,
          etc.</I></LI>
          <LI>Allow the user to add to or remove from properties the default set
          of properties.</LI>
        </OL>
        <LI>Task creation</LI>
        <OL TYPE="a">
          <LI>Provide a list of "standard" tasks to insert into the project.<BR>
          <I>This would be tasks like &lt;javac&gt; and
          &lt;javadoc&gt;.</I></LI>
          <LI>Generate default init, compile, javadoc, and clean targets.</LI>
        </OL>
        <LI>Creation review.</LI>

          <LI>Provide a review of the contents of the generated build.xml
          file.</LI>
