Note: This book is still fairly new. If you find errors, please let me know.
In this book we will implement a simple static blog generator in Haskell, converting documents written in our own custom markup language to HTML.
- Implement a tiny HTML printer library
- Define and parse our custom markup language
- Read files and glue things together
- Add command line arguments parsing
In each chapter of the book we will focus on a particular task we wish to achieve, and through the chapter we'll learn just enough Haskell to complete the task.
There are many Haskell tutorials, guides and books out there. Why read this one?
There are probably more, but here are a few possible pros:
- It's relatively short - most Haskell books out there are hundreds of pages long. This book (when exported to PDF) is roughly 150 pages long.
- It's project oriented. Many Haskell books teach Haskell by teaching the underlying concepts and features in a neat progression. In this book we try to build a program, and learn Haskell on the way. This will be a pro to some, and a con to others. There are other tutorials like this. The most notable ones are Beginning Haskell and Haskell via Sokoban.
- It's online, which means corrections are easy to make.
- It's free.
There are probably more, but here are a few possible cons:
- It may lack depth - many, much longer Haskell tutorials are long because they go deeper into the nuts and bolts of each feature.
- It may not cover as many features or techniques as other tutorials - we try to cover features as they pop up in our implementation, but we will probably miss features that aren't as important for our tasks, while other resources may try to cover many different use cases.
- It is very new and not "battle-tested". Who knows if this is a good approach to learning Haskell? Maybe you could help with that!
- It doesn't have a technical editor, making the book not as good as it could've been.
