Domain specific language creation

A method for creating a domain specific language for a business, the method comprising:

• identifying objects for the domain specific language, wherein the objects correlate to tangible aspects of the business;
• identifying operators for the domain specific language, wherein the operators describe actions that can be performed on or between the identified objects;
• identifying rules for the domain specific language, wherein the rules describe constraints on the objects and operators that correlate to tangible limitations in the business;
• and
• incorporating the objects, operators, and rules into a domain specific language external from a compiler but compatible with a rule interpretation engine inside the compiler.

An apparatus comprising:

• a tool for authoring rules for validation, in a rule description language created for authoring rules for validation, of a domain specific language;
• a tool for authoring rules for type checking, in a rule description language created for authoring rules for type checking, of the domain specific language;
• and
• a tool for authoring rules for formatting, in a rule description language created for authoring rules for formatting, of the domain specific language.

A program storage device readable by a machine and tangibly embodying a program of instructions executable by the machine to perform a method for using a domain specific computer language to extend an existing computer language, the method comprising:

• creating a rule for validation for a compiler, the rule for validation created in a rule description language created specifically to describe rules for validation, the rule defining a part of the domain specific computer language;
• examine source text to identify a domain specific language to use for compiling;
• and
• compiling the source text using a compiler for an existing computer language using the identified domain specific language, wherein the compiler contains a rules interpretation engine that runs the rules for validation for the identified domain specific language, wherein the rules for validation are external to the compiler.
