![Contextual Parsing With The Chain Method [Parser Combinators From Scratch] Episode 4 @LowByteProductions](https://i.ytimg.com/vi/nqNzWgSRCeg/maxresdefault.jpg)
Uploaded August 2019 | Updated September 2026, 2 weeks ago
In this episode we will write the method `Parser.chain(fn)` which utilises functional programming concepts to empower our system with contextual abilities!
What that really means is that we can look at what we've previously parsed, and choose the next parser accordingly.
=[ ℹ About ℹ ]=
During this series we will develop an understanding of the concept of parsing, and build our own parser combinator system from scratch. The system we build will be capable of parsing both binary and text data. We'll make use of both object-oriented and function programming principles to develop an effective and intuitive library.

This mini series is all about binary. Over the course of the series, well be building a library that gives us precise control of every bit and operation.
Youll learn how the logical and arithmetic operations work, how different kinds of numbers are encoded, how to set, clear and toggle bits, and how we can create representations of structured binary data.
1. Bits
2. Operations
3. Unsigned Numbers
4. Addition
5. Zero Extension
6. Twos complement
7. Overflow Addition and Sign Extension
8. Shifting
9. Setting, Clearing, and Toggling Bits
10. Endianness
11. Structures
