Changes:
19.08.2008
Dependency check for composed grammars added.
Might need some further improvements.
09.08.2008
Inspecting environment variable ANTLR_HOME to detect and add
antlr- and stringtemplate libraries to the classpath
09.08.2008
Removed routine checkGenerateFile. It got feeble with the
introduction of composed grammars, e.g. "import T.g".
From now one it is always antlr itself via the depend option
which decides about dependecies
31.12.2007
With option "depend=true" proceed even if first pass failed so
that ANTLR can spit out its errors
31.12.2007
Support the -Xconversiontimeout option (Jim Idle)
21.10.2007
Evaluation of dependencies via ANTLRs 'depend' option.
Added noprune and nocollapse option.
'grammar parser' will be recognized.
17.05.2007
Adapted the grammar type recognition to the changed naming conventions for tree parsers.
Compiled the antlr3 taks with -source 5 -target 5 for compatibility with Java 5.
Dropped trace, tracelexer and traceparser options as they are not supported by antlr any more.
Added depend and dbgST options.
Added project "SimpleTreeWalker" as an example for a multi grammar project.
How to build the antlr3 task:
Prerequisites:
1) apache-ant-1.7.0 installed
2) antlr jar files (antlr-3.1b1.jar, antlr-2.7.7.jar and stringtemplate-3.1b1.jar)
contained in the CLASSPATH environment variable
3) Java 5 or Java 6 installed
javac -source 5 -target 5 -classpath C:/Programme/apache-ant-1.7.0/lib/ant.jar org/apache/tools/ant/antlr/ANTLR3.java
jar cvf antlr3.jar org/apache/tools/ant/antlr/antlib.xml org/apache/tools/ant/antlr/ANTLR3.class
a) d2u.tp
Simple example on how to use the antlr3 task with ant
b) simplecTreeParser.tp
Example on how to build a multi grammar project with ant.
c) polydiff_build.zip
Example build file for polydiff example grammar added.
d) composite-java_build.zip
Example build file for composite-java example grammar added
