The latest version available is 2.7. You can obtain it from here: toolc-reference-2.7.jar.

You can run it as follows:

java -jar toolc-reference-2.7.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-2.7.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:

Usage: ./toolc [options] <file>
Options include:
 --help        displays this help
 --tokens      displays the list of tokens
 --eval        evaluate the program directly instead of generating code
 --main        displays the name of the main object anx exits
 -d <outdir>   generates class files in the specified directory

We welcome bug reports! Please use the forum on Moodle for this purpose.
