How to generate output in same namespace as config?

[morganhein]

Have you read the project readme?

• [x] Yes, but it does not include related information regarding my question.

Describe your question I have an situation that is maybe not-idiomatic, but we have some unique constraints.

I need to generate files in the same directory/namespace as the goverter config. The file gets generated, but the generated file tries to import the current namespace, which obviously doesn't work.

Is there some config/flag I can get goverter to detect it's working with a single namespace, and doesn't need to import itself?

I forked goverter and mangled the runner_test.go and added a scenario that generates output in the same package as the imported models/extended methods, and it worked... which leads me to believe something in application bootstrapping is just assuming a namespace must always be imported?

File structure is as follows:

public-api/pkg/button/goverter_input.go
public-api/pkg/button/some_models.go
public-api/internal/service/models/more_models.go

and I want to generate to:

public-api/pkg/button/converter_gen.go

Error is as follows:

-: import cycle not allowed: import stack: [github.com/morganhein/public-api/pkg/button github.com/morganhein/public-api/pkg/button]

// Code generated by github.com/jmattheis/goverter, DO NOT EDIT.

package button

import (
    models "github.com/morganhein/public-api/internal/service/models"
    "github.com/morganhein/public-api/pkg/button"    // <--- don't need this, and references here should not require a namespace
)

You need to define the absolute package path via -packagePath when calling goverter, then only necessary imports will be done.

Example:

goverter -output=./generated.go -packageName=simple -packagePath=github.com/jmattheis/goverter/example/simple github.com/jmattheis/goverter/example/simple

Jannis, thanks for the quick response!

I tried that and it does not work. Here's some screenshots illustrating:

Am I missing something?

[morganhein]

The unionpacific_edi.go is the goverter input here. That was not clear.

[morganhein]

I think I see the issue. The package path is a go path, not a file path....

edit doesn't work still..hmmm

[jmattheis]

You need to delete the old generated file. Goverter needs type information for generating the converter, but currently there is an import cycle, so it can't compile the code.

[morganhein]

Ugh. That's a little embarrassing.

Case closed. Thank you!

No problem, I'll improve the error message. It'll look like this:

could not load package github.com/jmattheis/goverter/execution

/ABSOLUTE/execution/input.go:6:1: expected declaration, found oops

Goverter cannot generate converters when there are compile errors because it
requires the type information from the compiled sources.
