Successful Domain-Specific Languages ? Which one do you use? [closed]

Answer 1

Google's web search supports some increasingly sophisticated parametrization

You could argue that this is one of the most widely used DSL's if even a small fraction of their userbase ever uses one of them as opposed to the standard list of words.

Answer 2

Awk provides is a domain specific language for the processing of semi structured textual data.
Many of the more powerful unix command line tools in wide spread use such as find and grep could be classed as having a domain specific language (even when limited solely to command line arguments)

Answer 3

The two (not already mentionned) which have impressed me most are:

• OpenSCAD for solid 3D modelling
• TaskJuggler for project management (!)

I'm a big fan of declarative DSLs. Operational DSLs (like Maple, Mathematica and R are nice too, but not that different from conventional langauges).

Answer 4

You can write a domain specific language in languages like Boo, but I think the very definition of domain specific indicates that most of the time it will be in a specific industry or even just a single company...

Wikipedia has a good introductory article on this.

This overview has an examples section with some good links.

Answer 5

1. Mak Stealth's language for programming charcter behaviors (Do not think it has a name)
2. Slang - Goldman Sachs language (I've heard of it but never used it)
3. CMS-2 Navy programming language

Answer 6

Erlang was originally a telecom-specific language, although it is now (occasionally) used as a general-purpose language.
