What is WildCAT?
----------------

WildCAT is a Java toolkit/framework to ease the creation of
context-aware applications. It provides an extensible set of sensors
to gather various kinds of contextual data, which can then be
organized into a structured and dynamic model representing an
application's execution context. Client application can query this
model and register listener to be notified automatically when specific
conditions occur.

WildCAT is a free software distributed under the terms of the GNU
Lesser General Public license and kinldy hosted by ObjectWeb at
http://wildcat.objectweb.org/

Getting the source
------------------

The latest releases are available from the project's website at
http//wildcat.objectweb.org/ 

You can get anonymous access to the very latest state of the source
using CVS at :pserver:anonymous@cvs.forge.objectweb.org/cvsroot/wildcat

Building
--------

WildCAT requires Java 5 (JDK 1.5) to build and run. The build process
uses Ant [1] (tested with 1.6.5), and requires the ANTLR parser generator
tool [2] and the JUnit framework [3]. Both are included in the externals/
folder, but must be made available to Ant. You can either:

1. Install the JARs system-wide (if you have the permissions) in Ant's
   optional tasks directory:

  % cp externals/antlr-2.7.6.jar $ANT_HOME/lib
  % cp externals/junit-4.1.jar $ANT_HOME/lib

2. Install the JARs user-wide:

  % cp externals/antlr-2.7.6.jar $HOME/.ant/lib
  % cp externals/junit-4.1.jar $HOME/.ant/lib

3. Tell Ant where to find the JARs using command-line arguments each
   time you invoke it, e.g.

  % ant -lib externals/antlr-2.7.6.jar:externals/junit-4.1.jar test



Building with Eclipse
---------------------

The project is setup for Eclipse [4], and you can install the ANTLR
Eclipse plugin [5] which provides an editor for ANTLR grammar files
and can be used to regenerate the parser from inside Eclipse
(right-click on the grammar file and select "Compile ANTLR grammar").
The automatic parser generation is disabled by default, as the code
generated by ANTLR triggers a lot of (innocuous) warnings which clutter
the Problems view. These warnings can be disabled with some manual
editing: 

1. Navigate to the org.objectweb.wildcat.standard package in the main
   source folder (src/).
2. Select all the generated Java files (Expression*.java) and do
   "Source > Organize imports."
3. Optionally, do also a "Source > Format" to make it more readable.
4. Annotate the lexer and parser classes (ExpressionsLexer and
   ExpressionsReader) with:
   
     @SuppressWarnings({"unchecked", "unused"})
     
   This tells the compiler not to worry that the generated code uses
   pre-Java 5 collections and declares lots of variables it does not
   actually use.
