The latest version is 1.9. You can obtain it from here.

You can run it as follows:

java -jar toolc-reference-1.9.jar program.tool

By default, toolc just compiles a Tool program to bytecode like your implementation will. You can however also use the reference implementation for other things. Try to run

java -jar toolc-reference-?.?.jar --help

for a list of available options. You can for instance print out some intermediate representations. Later in the project you will also be able to use the reference implementation to check that the operations you perform on the abstract syntax trees are valid.

The current options are:

--help               display this message
--version            display the version number
--tokens             show tokens of input program
--trees              show trees of input program
--pretty             show pretty-printed source of input program
--symbols            show pretty-printed source with unique symbol IDs
--lint               checks the validity of the program without generating classes
--main               prints the name of the main object to stdout
--check-symbols      parse the program annotated with unique symbol IDs

2011-11-17       1.7      toolc now stores positional information in bytecode.
                          It also stores the name of the source file.
                          Classes cannot be named 'Object'. Same restriction applies to main object.
