How to get back an ISO 639-1 code

[kensanata]

How do I get back the ISO 639-1 code for a language? My use case is a text that is turned to HTML and I want to set the lang attribute, e.g. lang="en" or lang="de".

Sadly, I'm new to Go, so this is what I have in a test and I always get back EU for English.

func TestLanguage(t *testing.T) {
	language := lingua.English
	if lingua.IsoCode639_1(language) != lingua.EN {
		t.Logf("Language: %s, ISO 639-1: %s", language.String(), lingua.IsoCode639_1(language).String())
		t.Fail()
	}
}

Result:

    page_test.go:84: Language: English, ISO 639-1: EU

I guess I'm confused about the IsoCode639_1 func and type?

Hi Alex, it's as simple as calling lingua.English.IsoCode639_1().

Conversely, if you want to get the language for a specific ISO code, just call lingua.GetLanguageFromIsoCode639_1(lingua.EN). While I'm thinking about it...it probably makes sense to implement lingua.EN.Language() for the next version. That would be much more elegant. Thank you for pointing me to this idea. (-:

Thanks! That worked. :)
