Assignment Compiler Files

All sources for the assignment PL0 compiler are available as a2.zip (below). Please be sure to use the version for this assignment and not the one used for the tutorials or another assignment. There are differences (like the lexical tokens you need for this assignment are only defined in the assignment version).

For the most part you will not need these.

Please ensure you follow the course Piazza bulletin board for any updates and further information on the assignment. Read all the fine print below in detail before you start! And, most important, when you have finished implementing the assignment, come back and re-read the fine print again.

Do not use imports for external packages other than those in java.util.*. Note that IntelliJ may offer the option of importing an external package to resolve an issue; please avoid accepting this option because it will often add an erroneous import that you will not need. Such imports lead to the compilation failing in the environment in which your compiler will be assessed because that environment does not include the external libraries. Please check you are not importing external libraries before submitting.

You must only modify the files that must be submitted (see below).

You must not modify any other files because we will be testing your implementation using the existing other files with your submitted files.

Please do not reformat the files because we would like to just print the differences between the originals and the versions you hand in.

Please keep the length of lines in your files below 100 characters, so that we can print them sensibly.

Please avoid using non-standard characters, e.g. Chinese characters, including in the comments. Non-standard characters are not accepted by the Java compiler used to test your assignment and all comments should be readable by the person assessing your assignment.

Your implementation should be in Java Project language level 8. Set the IntelliJ preferences for the Java project language level 8 under Project structure then Project (or use the "-source 1.8" option to the command line Java compiler).

Please remove any debugging output before your assignment is submitted because debugging output will cause your program to fail our automated testing of your assignment.

Either avoid using tabs or set your tabs stops to 4 spaces (this is the default for IntelliJ/Eclipse) so that your files will print sensibly.
