In a nutshell

01 02 03 04

Useful Error Messages

Every single error that the compiler encounters will print a rich error message for the user

Lists

We have lists for primitive as well as non-primitive data types such as point, string

Built-in function Libraries

Built-In functions written and compiled in our own language, have the ability to be included as libraries

C++

Our backend compiles down to C++, allowing us to re-use code without re-compiling

Semantic Checking

Maintaining a Symbol table Type Checking Scoping and visibility

The meat of the compiler Undeclared, redeclared functions and identifiers Validation according to language specs Static, block

Error Reporting

Parser: On Error, report error, continue parsing. Program: Output: Program: Output: Scanner: On Error, report error, stop scanning.

Test Driven Development

New test for every feature Goal part 1: Make test pass Goal part 2: Fail no other tests Pass Tests Fail Tests

Proceeded by the word “Pass” Tests that we know should pass Proceeded by the word “Fail” Tests that we know should fail

Takeaways

Pair Programming saves lives. OCaml is awesome, give it time. Use Prof. Edwards’ slides. Choose teammates wisely, you’ll be stuck with them for the term.
