Sample Issue Description for Problem Statement

Linter for Concerto [This just a sample from last year, this project has already being implemented]

Write a linter in TypeScript for Concerto Source files. It should make use of existing functionality to validate the Concerto DSL syntax and JSON AST of Concerto model against a set of rules. Rules should be defined in Typescript and which rules are run should be configurable. You may be able to make use of a tool like Spectral as the framework for defining our own rules over the Concerto AST (JSON).

Expected Outcomes:

A tool that allow users to:

• Specify the naming of declarations. E.g. all names of scalars should be in camel case.
• Specify the naming of properties, enum cases e.t.c
• Specify which language features can be used. E.g. disallow maps, disallow forward references in regex validators.
• Enforce the use of certain features. E.g. all string properties should have a length validator.
• Enforce the use of @term decorators on all declarations and properties e.t.c
• All concepts in a namespace should extend a given concept
• All concepts in a namespace must have unique names across multiple namespaces

Skills required/preferred:

Algorithms, Functional programming, Back end development, NodeJS, TypeScript

Possible Mentors:
