startup screen i18n

[martinl]

Language settings doesn't affect start up screen. When switching e.g. to 'ja' in GUI settings, GRASS starts with non-localized welcome screen

A language override has been requested. Trying to switch GRASS into 'ko'...
Failed to enforce user specified language 'ja' with error: 'unsupported locale s
etting'
A LANGUAGE environmental variable has been set.
Part of messages will be displayed in the requested language.

Afterwards GUI starts localized. I remember that it worked in 7.0.0beta3.

Not a bug. Everything works as expected. Try to select "de" and you will see that it works.

The source of problem is - someone (username martinl) decided that English language is the only language that matters and backported startup screen changes (r64496) that touched a lot of strings. (This would be a huge no-no in any large project, like KDE, where breaking strings so close before release is considered to be something like a deadly sin.) As a result - for most of languages GRASS 7.0.0 was shipped with a untranslated welcome screen.

Are you sure that the error message in the original report is influenced by whether the string is translated or not? The ticket might be still valid.

But you are right, it works for me with de. However, with ja or ko I get non-translated start up screen (even Quit and Help are not translated, not only the new strings). The error message (in command line) is:

Failed to enforce user specified language 'ja' with error: 'unsupported locale setting'
A LANGUAGE environmental variable has been set.

The error is coming from source:grass/trunk/lib/init/grass.py#L807​:

                try:
                    encoding = locale.getpreferredencoding()
                    normalized = locale.normalize('%s.%s' % (language, encoding))
                    locale.setlocale(locale.LC_ALL, normalized)
                except locale.Error as e:
                    # If we got so far, attempts to set up language and locale have failed
                    # on this system
                    sys.stderr.write("Failed to enforce user specified language '%s' with error: '%s'\n" % (language, e))
                    sys.stderr.write("A LANGUAGE environmental variable has been set.\nPart of messages will be displayed in the requested language.\n")
                    # Even if setting locale will fail, let's set LANG in a hope,
                    # that UI will use it GRASS texts will be in selected language,
                    # system messages (i.e. OK, Cancel etc.) - in system default
                    # language
                    os.environ['LANGUAGE'] = language
                    return

This makes sense but I think we miss somebody who would check that people fulfill this rule when backports are done before release. Also writing it down is a good idea. This is the right place to do it: wiki:Submitting/General

It's still better to ship the new startup screen than the old version. It's quite simple answer.
