Background

#879 defines the business requirements driving the syntax and code generator updates listed below.

Related contributions

• #909 addresses the DSL syntax requirements.
• #928 and #1024 address the default code generator requirements.
• #931 introduces support for dynamic validation injection in the default code generator.

Code generator requirements

Full support for DSL expressions, functions, and typeAlias definitions with conditions in Rune DSL is currently limited to the Java code generator.

Specifically, the following syntax and validation features are required for non-Java code generators (e.g. Python) to fully implement the contributions described above:

1. DSL Expressions
2. Type Alias and conditions resolution
3. Function definitions
4. Validator generation and dynamic injection

The completion of these features will enable consistent DSL behaviour across all supported language generators and allow downstream consumers to adopt conditional constructs and validation capabilities without restriction.
