How to use oops, slog and contexts together

main.go

package main

import (
	"context"
	"errors"
	"log/slog"
	"os"

	"github.com/golang-cz/devslog"
	"github.com/samber/oops"
	slogctx "github.com/veqryn/slog-context"
)

func initLogger() {
	h := slogctx.NewHandler(devslog.NewHandler(os.Stdout, nil), nil)
	logger := slog.New(h)
	slog.SetDefault(logger)
}

var ErrError = errors.New("some test error")

func doSomethingElse(ctx context.Context) error {
	return oops.FromContext(ctx).
		In("doSomethingElse").
		Code("TEST_ERROR").
		Public("this is a test error, no need to react on it").
		Tags("test").
		Hint("this is a test error").
		Wrapf(ErrError, "test")
}

func doSomething(ctx context.Context) error {
	return oops.Wrap(doSomethingElse(ctx))
}

func main() {
	initLogger()

	ctx := oops.WithBuilder(context.Background(),
		oops.Tenant("tenant-uuid", map[string]any{"name": "Acme Corp"}).
			User("user-uuid", map[string]any{"name": "John Doe"}),
	)

	ctx = oops.WithBuilder(ctx, oops.FromContext(ctx).With("foo", "bar"))

	ctx = slogctx.Prepend(ctx, slog.String("appendKey", "appendValue"))

	err := doSomething(ctx)

	if err != nil {
		slog.ErrorContext(ctx, "Something went wrong", "error", err)
	}
}
