There are some DSL articles in the pipeline for Ruby Code & Style[0], so hopefuly they'll help you, but a more detailed book on DSLs would be interesting.

Not a book, but I'm starting a new blog with a series of articles on how I'm
re-visioning RHDL - A Ruby-based DSL for describing digital circuits. HDLs
(Hardware Description Languages) are likely not familiar to folks here so let
me give you a bit of background: HDLs such as VHDL and Verilog are used heavily
now for designing chips. The semantics of an HDL are mostly quite different
from the semantics of a regular programming language; think of HDLs as dataflow
languages which also describe circuit structure and/or behavior. Even if
you're not interested in HDLs, this dataflow aspect might be interesting
for some as a method for dealing with concurrency.
I'll try to put post up at least every other day or so. Feel free to post
comments and questions. I want this to eventually lead to a series of
articles and I figure this is a way of writing them and getting immediate
feedback. Here's the link:
I don't know of anything specific. Some of the lisp books, for example Peter Seibel's book 'Practical Common Lisp' (<http://www.gigamonkeys.com/book/> the pdf is freely available) touches on the subject but in CL the idea is kind of fundamental so it is sometimes not specifically named as DSL and it is all through the book (in CL you basically program by building DSLs). Same with Paul Graham's book 'On Lisp' <Paul Graham; also with a freely available pdf version. Both books are excellent, Graham's is in my short-list of Important Software Books.
In the Ruby world, the best I've read is David Black's 'Ruby for Rails'. It isn't available yet (it is being released chapter by chapter at Manning). It also isn't explicitly about DSLs but it is one of the best that I've seen on the subject and discusses Rails as a DSL.
Cheers,
Bob

Its not Ruby related, but you might want to look at "Starting Forth" and
"Thinking Forth". These are classic texts, and the terminology
(buzzwords) are not the same as today, but still a pleasure to read.
Maybe someone can translate this example to Ruby sometime. It seems so
natural in Forth though. Its weird how sometimes largely forgotten
things still have the power to teach us

I would *love* to see a book about ruby DSLs. After seeing a little
about how other people design them at RubyConf, it's become clear to
me that there are quite a number of different good ways to implement
DSLs in ruby. Why this should be, I don't know. It doesn't seem to
have been a deliberate feature of the language. I know of no such
book, but I hope someone out there will consider writing one, if they
aren't already.
If it helps, you can think of a DSL as just a particularly clear and
naturalistic API.
You might want to read chapter 6 of The AWK Programming Language (Aho,
Kernighan, Weinberger). The title of that chapter is 'little languages'.
The chapter includes the following examples (in AWK of course):
assembler and interpreter
drawing graphs
a sort generator
a reverse-polish calculator
an infix calculator
recursive-descent parsing

Along the same lines, the O'Reilly Lex and Yacc book (by John Levine and
several others) has some little DSL examples - a menu generation system
and whatnot.

Then again, maybe not. Wonder what the odds are. If nothing else, we
certainly seem to agree on the article.

Good stuff. Covers all of the basics, and has clear examples of the
meta-programming needed for a DSL. Thanks much to all involved.
Thanks for the pointers, I've read the AW AWK Programming Language and
O'Reilly lex & yacc books. From the presentations I've seen on Ruby
DSLs, it doesn't seem like folks are writing parsers -- it seems more
like Lisp macros where the program is being written as its being
interpreted.
In the same way that Ruby's attr_accessor creates getter/setter
methods for the specified symbols (instance variables), DSL 'gurus'
have created similar constructs which implement the 'mini language'
without the drugery of writing a parser/compiler.
It looks like there are no "How to write DSLs in Ruby" books currently
available or planned.

Sean
