overwriteHandler=false does not create new handlers

[siom79]

I have created a first version of my service and implemented the stubs generated by light-codegen. Now I want to add a new path to my openapi specification. Hence, I run light-codegen with the option overwriteHandler set to false in order to avoid losing my changes on the existing handlers.

I expected that the new handler gets created, but it is not.

Once I set overwriteHandlerto true, the new handler is created but I lose all my changes of the existing handlers.

When the overwrite flag is set to false, it does not generate the handlers in the .handler. package of your choice.
This is a valid point, Martin

@siom79 The generator is stateless and it doesn't know how many handlers have been generated before to decide if a new handler is added. The only option for us is to check if the file exists in the generator. I will open an issue to address it. Meanwhile, you can regenerate the code to a separate folder and do a full-text comparison.
