Building DSLs in GoLang using gRule and Protobuf

Domain Specific Language (DSL) is a programming or scripting language dedicated to a specific problem statement or business domain compared to a general-purpose programming language. The syntax and semantics are custom-made for a particular task to enable the domain experts to express relevant business domain ideas and rules clearly and succinctly. DSLs powerfully encode business logic directly into code and microservices, defining conditions and operations directly on domain entities to drive decisions or workflows.

We interact regularly with several well-known DSLs in daily computing. SQL (DDL/DML) is a classic example used for interacting with databases. Similarly, HTML is a DSL designed specifically for structuring web pages, whereas CSS acts as a DSL to handle visual styling and layouts. Regular Expressions (Regex) are another powerful DSL for pattern matching within text. In infrastructure automation, DSLs like Terraform’s HCL (HashiCorp Configuration Language) simplify provisioning and managing cloud resources. Similarly, tools like Ansible and Chef use their own DSLs to simplify and standardize infrastructure configurations. While these are widely adopted, creating your custom DSL can significantly streamline and enhance interactions specific to your own business domain.
