How can I fetch the default locale (server locale not from the request) in Golang

[prabhakara...@gmail.com]

Hello All,

  I'm a newbee to Golang and am trying to fetch the default server locale. Can you help me how I can fetch the default server locale in golang?

In other words, I'm looking for the Java equivalent code in golang i.e 'Locale.getDefault()'

Thanks

Anish

Serving to a locale may be helped with this blog: https://blog.golang.org/matchlang

This library looks like it has implementations for finding the OS locale: https://github.com/cloudfoundry-attic/jibber_jabber

Go doesn't use locales in the same way that Java does. If you tell us
what you want to do with that information, we may be able to help.
You may want to look at https://godoc.org/golang.org/x/text .

The intention is basically to send out translations from the deployed shard. Hence,we are trying to find the locale of the server locale. Because of some reason, we cannot extract this as an environment variable on the shard or get it from the client.

Best

What operating system?

What format do you want for the locale?

For what it's worth, I don't usually call the timezone a "locale". In
programming, "locale" usually refers to language related issues. See
https://en.wikipedia.org/wiki/Locale_(computer_software) .

To get the timezone name, see https://golang.org/pkg/time/#Time.Zone .

My bad. 

I was referring to the same.Something which is packaged in go giving a standard locale ID as q_AL, ar_DZ

Java’s Locale.getDefault returns (if not overridden) the values from the system property “user.language” and “user.region”. If these are not set, it simply returns “en”. See http://hg.openjdk.java.net/jdk8u/jdk8u60/jdk/file/935758609767/src/share/classes/java/util/Locale.java

For Linux: These system properties (if not overridden) are set on Linux by interpreting the environment variable “LANG”. See https://docs.oracle.com/javame/config/cdc/cdc-opt-impl/ojmeec/1.0/runtime/html/localization.htm

Thus the equivalent code in Go would be to access this environment variable. Thus a simple `locale = os.Getenv("LANG")` or as Jibber-Jabber does it:

```
locale = os.Getenv("LC_ALL")
if locale == "" {
locale = os.Getenv("LANG")
}
```

If it is correct that, as you stated, that you have no access to environment variables, you won’t be able to conclude more than “en” to be compatible with Java’s behavior.

Thanks for the details. Had a look earlier at the code mentioned by Jibber-Jabber as you mentioned. Will post the status as soon as I try this out.

Cheers

Just an update on the same. Even the library from "Jibber-Jabber" seems to be returning only empty string values. 

Forced to set this as an ENVIRONMENT_VARIABLE for the time being and moving on.
