[REBOL] Re: Language-oriented programming

From: edoconnor::gmail at: 20-Sep-2007 14:24

Language-oriented programming is interesting and caused a small stir a couple of years ago. Unfortunately, it hasn't gone anywhere, and I think we won't see much in this realm until an app or framework emerges that really drives the point home. Currently Ruby-on-Rails, and more generally the Ruby language, has gained notoriety for DSLs, although Python also has examples. Perl recently included grammars-based parsing, so it could be a contender as well. REBOL, of course, has had its sights on dialects for a long time. I'm no expert, but the challenges I see for dialecting are: 1. Developers seem more comfortable with a neutral, standards-based format such as XML. This de-couples the data from the processing language and doesn't mandate a single tool like REBOL at both ends to interpret messaging transactions. 2. Dialects (as I've understood them) can only be composed of REBOL values. Although REBOL has a rich variety of values, it is possible to encounter datatypes which will not load into REBOL. 3. Parse dialects (as opposed to specialized groups of rebol statements) require a solid foundation in parse, and the current docs are a bit thin. I would be very interested in learning what R3 might bring to reassert REBOL's prowess in dialecting. If somewhere down the road there are plans for the following, things could get more interesting: A) a built-in tool for creating/editing parse dialects B) stronger XML, JSON, YAML support C) ability to create new datatypes Ed On 9/20/07, Richard Boyd wrote:
