Domain Specific Language Framework

1 post · May 2022

What this trail covers

GitLab has developed Lingo, a micro language framework in Go for building Domain Specific Languages (DSLs). Lingo is designed to be simple, flexible, and composable, allowing developers to easily integrate custom types and functions without modifying the core parser or processor. It uses S-expressions as its foundation and is implemented in approximately 3K lines of pure Go code. Lingo aims to simplify the creation and evolution of embeddable DSLs for specific use cases, such as data generation.

  1. Lingo: A Go micro language framework for building Domain Specific LanguagesThis post introduces Lingo, a new micro language framework developed in Go. It details the challenges of designing DSLs, the limitations of existing tools, and the design principles behind Lingo: stability, flexibility/composability, and simplicity. The post also provides a practical example of using Lingo to build a data generation engine for generating CSV files, demonstrating its capabilities with custom functions like `oneof`, `join`, `genfloat`, and `times`.
