1ANTLR version 3 supports target language generation for the lexical 2analyzer and parsers. Objective C was supported previously but had not 3been brought up to date for some time. This release is built on the work 4by Kay Roepke, Ian Michell and Alan Condit. 5 6The project is currently working sufficiently for me to use it in compiling 7my grammar and tree walker. I am sure that it still has some bugs but I have 8fixed all of the bugs that I have found so far. 9 10The project consists of an Objective-C runtime framework that must be 11installed in /Library/Frameworks. 12 13It also requires the installation of the String Template files to 14support the target language code generation. Hopefully, at some point 15they will be incorporated into the ANTLR release code, so that the 16individual user doesn't have to do anything but load the framework into 17the proper location. However, for now you need to create an ObjC 18directory in antlr-3.2/tool/src/main/resources/org/antlr/codegen/templates 19and then copy the ObjC ".stg" files to 20antlr-3.2/tool/src/main/resources/org/antlr/codegen/templates/ObjC/*. 21 22There is also a java file ObjCTarget.java that goes in < 23antlr-3.2/tool/src/main/java/org/antlr/codegen/ObjCTarget/Java>. 24 25If you are using Antlr3.3 the code from here is included with the Antlr tarball. You just need 26to copy the ANTLR.framework to /Library/Frameworks.
