basic generator for the boilerplate of an endpoint definition #70

[dahernan]

This is a starting point to generate boilerplate code for a given endpoint (I don't expect this PR to be merged, could be use it as inspiration, or maybe try another approach to solve the problem).

Steps to generate boilerplate:

• Given the endpoint definition here process/process.go (similar to what is expose in issue Automatically generate the boilerplate #70)
• The file must be anotated with:

//go:generate go run ../gen-cmd/main.go packageName
//go:generate go fmt

• Generate the boilerplate doing:

$ cd process
$ go generate

• The generated file will be process_definition.go

Know issues

• Uses relatives paths to refer the template and the generator command
• I don't like the way I get the packageName as an argument in the generation, to use it as a filename

[dahernan]

Not nice to get the file from the packageName requires the convention of the file packageName.go

@dahernan FYI, rather than running go fmt you can use stdlib's go/format package to format your generated code before writing it to a file.

Thank you very much for the initial code and thoughts! I will doubtless refer to this in any future work. I am tidying up the issues and PRs and will close this for now.

My pleasure, thank you 😄
