|Why Programming Languages?|
This course presents a set of ideas about programming. Most of the ideas count as general programming language concepts; they are such good ideas about programming that they are baked into practically all modern programming languages. Other ideas presented in the course count as functional programming, because they have been emphasized in a certain family languages—althoughs that distinction grows less relevant as programming languages evolve, since good ideas about programming tend to get absorbed into general programming languages and practice.
The course presents those ideas primarily by having you implement interpreters, although you will also implement some type checkers and compilers. Those kinds of programs are particularly well suited to functional programming techniques, which is why the course gives you practice writing functional programs. At the same time, the process of implementing a programming-language construct as part of an interpreter provides a deeper understanding of the concept than merely using the construct in a few programs.
The ideas presented in the course will help students more easily recognize the capabilities of current and future programming languages. The ideas should also help students become better programmers in general. The goal is of the course is not to prepare students to implement new programming languages, although the concepts of the course are certainly a prerequisite for any student who has that goal.
Students taking the course should have significant programming experience already, but no previous experience with functional programming is required; the course will teach those concepts. We will implement interpreters in the Plait language, which is a dialect of Racket. Naturally, no experience with Plait or Racket is assumed.
All lectures for the course are presented online in video form. In (virtual) class, students will present homework solutions and/or work through homework-like problems as a group.
For a detailed list of topics covered by the course, see the schedule for Fall 2020.
No textbook is required, but the course content is derived from the following book:
|Programming Languages: Application and Interpretation, Second Edition|
|Also available as PDF|
As an extra resource, you may want to consult the first edition.
|Course Schedule and Homework|
The course Canvas page contains a tentative schedule in the modules listsing, which will be revised throughout the semester. Video lectures, slides, and programs, and solutions to in-class exercises for each lecture will be posted there.
Homework assignments are also posted in Canvas. Homework is typically assigned weekly, and it is usually due the following week, but there will be exceptions. Homework grades and solutions are accessible from the handin-status server.
We'll use the DrRacket programming environment, version
Install the uu-cs3520 package by using the Install Package... menu item in DrRacket's File menu, and type
in the box.
After restarting DrRacket, a Handin button will be available for submitting homework assignments. You must create a special handin account, as described for HW 0.
Installing cs3520 will automatically install the packages plait and plai-lazy.
