This has been a very informative lecture, it explains a lot of the questions I had on how to write and implement my own processing language in a java application I would like to develop. The course does run fast, and I would say is for a more senior programmer, and one may have to repeat watching
Building a Parser from Scratch
Understand the underlying theory behind recursive descent parser for a programming language
Updated on Sep, 2023
Language - English
Parsing or syntactic analysis is one of the first stages in designing and implementing a compiler. A well-designed syntax of your programming language is a big motivation why users would prefer and choose your language.
Recursive descent parsers are the group of parsers that are widely used in practice in many production programming languages. In contrast with automated parsing algorithms, the manual implementation allows having full control over the parsing process and handling complex constructs, which may not be possible in the automatic parsers.
Besides, implementing a full manual parser from scratch allows understanding and seeing this process from inside, demystifying internal structures, and turning building parsers into an interesting engineering task.
In the Building a Parser from Scratch class, we dive into pure practical implementation, building and learning different aspects of parsers.
