# Language-Oriented Programming

> An approach in which each problem domain gets its own language, with a type checker and an evaluator, and solutions are written in it.

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Domain-Specific Language (DSL)](https://banes-lab.com/records/architecture/domain-specific-language.md) and before [Model-Driven Architecture](https://banes-lab.com/records/architecture/model-driven-architecture.md).

## Repair

- Refactored by: Consolidate DSL, Add Tooling
- Detected by: multiple inconsistent rule/config syntaxes
- Violated by: proliferation of informal unvalidated DSLs
- Measured by: language consistency/tooling
- Enforced by: grammar/schema validation

## Requires

- [DSLs](https://banes-lab.com/records/lexicon/dsls.md)
- [Code Generation or Interpreters](https://banes-lab.com/records/lexicon/code-generation-or-interpreters.md)

## Reinforces

- [Domain Modeling](https://banes-lab.com/records/lexicon/domain-modeling.md)

## Enables

- [High-Level Domain Expression](https://banes-lab.com/records/lexicon/high-level-domain-expression.md)
