Building a High-level Compiler from scratch
What you'll learn
- High-level compilers pipeline
- AST (Abstract Syntax Tree) transformation
- Code generation
- Syntactic sugar
- Runtime modules
- Cooperative multitasking
- Lightweight processes (aka "Green threads")
- Message-passing mechanism
- Concurrent execution of processes
- Parsing tools
- Interest in building programming languages
- Basic data structures (lists, trees, traversal)
If you would like to explore the world of compilers and implement your own programming language, starting from the high-level compilation is a good hands-on practical approach, and which we apply in this class.
Often related books on compilers go to theoretical aspects, stucking in parsing, regular grammars, etc – not explaining how actually to build a practical transpiler. I believe we should be able to build a transpiler for a full programming language, end-to-end, in 2-4 hours — with a content going straight to the point, showed in live coding sessions as pair-programming and described in a comprehensible way.
Implementing a transpiler will also increase your engineering level, as it touches several aspects of data structures and algorithms.
An optional prerequisite for this class is the Building an Interpreter from scratch (aka Essentials of Interpretation) course, where we build an AST-interpreter for a full programming language. Unless you already have understanding of how programming languages work at this level, i.e. what eval, a closure, a scope chain, environments, and other constructs are — it is recommended to take the interpreters class as a prerequisite.
Who this class is for?
This class is for any curious engineer, who would like to gain skills of building complex systems (and building a transpiler for a programming language is an advanced engineering task!), and obtain a transferable knowledge for building such systems.
If you are interested specifically in compilers, PL and Type theory, and want to build a transpiler for your programming language, this class is also for you.
What is used for implementation?
Note: we want our students to actually follow, understand and implement every detail of the Transpiler themselves, instead of just copy-pasting from final solution. Even though the full source code for the transpiler is presented in the video lectures, the code repository for the project contains /* Implement here */ assignments, which students have to solve.
What’s specific in this class?
The main features of these lectures are:
Concise and straight to the point. Each lecture is self-sufficient, concise, and describes information directly related to the topic, not distracting on unrelated materials or talks.
Animated presentation combined with live-editing notes. This makes understanding of the topics easier, and shows how the object structures are connected. Static slides simply don’t work for a complex content.
Live coding session end-to-end with assignments. The full source code, starting from scratch, and up to the very end is presented in the video lectures
What is in the course?
The course is divided into four parts, in total of 18 lectures, and many sub-topics in each lecture. Below is the table of contents and curriculum.
Part 1: Transpiler pipeline
In this part we start talking about transpiler pipeline, parsing, code generation, and exploring AST nodes.
Part 2: Functions and Processes
In this part we focus implementing our runtime components, such as Process and Scheduler classes, and discuss cooperative multitasking.
Part 3: Pattern matching
In this part we implement packed data structures, such as Lists and Records, and also build support for pattern matching.
Part 4: Message passing
In the final part we implement the message passing mechanism, do a case study analysis, using the compiled code from Web, and build the final executable.
