There are sometimes code generators needs to be configured at runtime with certain properties to have code generated differently. Currently the Vorto generator doesn't have option to provide different configuration for the current generator, instead user has to create a new generator or have new version of the same model with different implementation. This forum is to explore the possibilities of configurable generators.

The example scenarios are discussed in this topic.

Few example usecase Scanarios:
1. If there is a generator written for Rest api, there is a possibility to generate rest api with standard jsr 311/339 or spring mvc (http:==projects.spring.io/spring-framework/) (assuming spring mvc is commonly used in enterprise ). Often this should be configured as a configurable parameter instead of writing new generator.
2. For generator written to handle Database related code, often there could be many different implementation of database (like mysql, mongodb, oracle etc). Each of the generated code have few minor changes only.

For these kind of scenarios, writing generator for every possible database vendor is not efficient. So, user should have option to provide settings at the runtime.

This section is discuss the above in detail.

Implementation options:

- Possible options could be, is to have a default properties file within generator and the properties are overriden at runtime by User supplied values from GUI or command line parameters depends on the context it's used.

Hi Vijay,

thanks for your suggestions and I agree, that would definitely be very useful!
To put your idea in other words, you want to have a generator configuration that is passed to the specific generator upon invocation time and based on these configurations it would handle the generation differently, right?

At the moment this input context is not implemented and would require a API change , e.g. to something like that

generate(InformationModel model, GeneratorContext context)

where the generator context would contain the mapping context and input key/value pairs coming from the UI / when invoking the generator.

Would you please raise a bugzilla feature issue about this, under component Code Generator?

Thank you + Cheers,

Alex
