I am trying to use a global variable defined in parent package in the internal package. There are no errors but none of the logs from internal package are printed. My assumption on order of init is: parent.go global variables and then init() from internal package; which seems right when tested with fmt.Println(). But looks like the call to ReplaceGlobals is dropped during compilation. Is there a way to fix it so that I can use global variable from internal package?
Here is the zap package I am using: zap. The API in question is discussed here. Here is the code snippet.
~/parent/parent.go
package main
import (
"log"
"go.uber.org/zap"
"parent/internal"
)
var (
logger = GetMyLogger()
undo = zap.ReplaceGlobals(logger.Desugar())
)
func GetMyLogger() *zap.SugaredLogger {
xx, err := zap.NewProduction()
if err != nil {
log.Fatal("error")
}
sugar := xx.Sugar()
return sugar
}
func main() {
logger.Infof("logger in main")
internal.New()
}
Then in ~/parent/internal/internal.go
package internal
import (
"go.uber.org/zap"
)
var logger *zap.SugaredLogger
func init() {
logger = zap.L().Sugar()
logger.Infof("init() from internal: %v\n", logger)
logger = zap.S()
logger.Infof("init() from internal: %v\n", logger)
}
func New() {
logger.Infof("New() from internal")
}
