Description

Currently jsii-pacmak seems to create a go.mod file even if --code-only is supplied.
Is there a reason for that?

Proposed Solution

Don't generate / include a go.mod in the output directory if codeOnly: true / --code-only is set for jsii-pacmak.

So --code-only doesn't mean to only generate source files, it means to not to build the package. In java, when you run --code-only, pom.xml is still generated with a list of dependencies, we just don't run mvn build and create a .jar file.

With Go, since the source code is the package artifact, the only difference with --code-only is that we don't create local.go.mod and run go build against that to verify that compilation occurs.

This is expected behavior. Can I ask what the use case is that you don't want to create go.mod?

[ansgarm]

Ah, thank you for the clarification, @MrArnoldPalmer 👍

The background is jsii-srcmak, where we decided to integrate just the Go code into the Go project of a user.
Currently the go.mod is simply deleted after copying everything and I just thought we could get rid of that step. But I just misunderstood that flag, so nevermind 😅

Going to close this. Have a nice weekend 👋
