Mark Jason Dominus authored a classic book about functional programming and other advanced techniques in Perl 5 called Higher Order Perl: Transforming Programs with Programs. I bought the book when it came out in 2005 and recently opened it back up after many years away from Perl. The book is still in print and Mark has graciously posted the full book for free download here.
This project is a C# implementation of the programs in the book that I'm doing to improve and update my C# skills and knowledge. I think I'll need to learn many features of C# 6 and 7 and maybe Roslyn to duplicate all of the code in the book.
The book follows the classic form of code interspersed with explanations. I'm re-writing all the code in C# (line for line where possible) and adding big picture explanations in a notes file in each chapter folder (e.g. Chapter1_Notes.md) and detailed explanations in code comments.
If you want to follow along you can download the book for free from this page.
Mark's explanations of the techniques and their benefits are very language-independent and timeless, so read the book, and when you come to some Perl code then look at this project for the C# version.
- There is one folder per book chapter containing one VS solution file per chapter, e.g. the Chapter1 folder contains Chapter1.sln
- Most of the chapter folders also contain a file of notes for that chapter, e.g. Chapter1_Notes.md
- Each chapter folder contains several folders, with from one to three book sections per folder and one .csproj for each group of sections, e.g. the Chapter1_1-1_3 folder contains Chapter1_1-1_3.csproj
- There is one class in one file for each book section, e.g. Chapter1_4.cs contains class Chapter1_4
- There are Demo_xxx() methods in each class to demonstrate the code from each section
- The Program.cs file calls all of the Demo_xxx() methods for the sections in its .csproj
