A book about how to write an interpreter from scratch

Hello, My name is Mehmet. I am the author of "Practical Interpreter Construction". I am not writing for promoting my book. It is a more story and a contra attitude than just announcing yet another book about compilers and interpreters. There are some books teaching compilers. When I decide to write an interpreter from scratch, I first googled about compiler books. I bought some of them but liked none of them because of the heavy theory they include. Also, I don't think that a practical programmer needs to read an even difficult to carry book. After some struggle and seek and then cancel, I found out James Hague's blog post exactly about what books to read if one wants to write an interpreter or compiler, here it is: http://prog21.dadgum.com/30.html As he suggests, I have read Jack Crenshaw's famous "Let's Build a Compiler" text, http://compilers.iecc.com/crenshaw It really is amazing text about compilers. I have learned a lot by reading Mr. Crenshaw's text. Despite it is a gem and it does teach a lot, there is something that puts off many in his text: it is target platform is Motorola 68K, besides, it does not teach much about writing an interpreter. It is more a compiler book. Then afterwards, I decided to write a book about writing an interpreter from scratch. There is parsing and interpreting expressions, strings, code comments, variables, arrays, while loops, if-else case and functions in the book. It is heavy-theory free and a practical book. You don't have to be a computer science student to read it. Any programmer can read it. I hope I will help many programmers to write their own interpreters and learn how interpreters work. It is a very useful mental process and it really is fun! Here is the book link on Leanpub.com: http://leanpub.com/pic Greetings, Mehmet Emin Coskun. ---
