I wanted to compare my settings of the Lyx document with the one of a
Help file (i have chosen Users Guide). However, the Text there is in
German, although I have set the language under
tools>preferences>language settings>English and under Document
settings>Language>English (USA).
What is wrong?
The default is for LyX to pick up language settings from the operating
system. At least, that is how it works with the linux operating system.
The environment variable LANG is queried. In My case, it is set to
nb_NO.UTF-8, so I get Norwegian menus. If LANG is not set, or is set to
C, then LyX falls back to the default language which is english. If you
set a language explicit in Tools->Preferences->Language, then that
language is used instead of the system language. So you can select
english there.
This only works for the user interface (menus and such.) Each document
has a language setting, which affect that particular language. As others
have pointed out, changing it does not translate the document to another
language - although some autogenerated text (Chapter/Kapitel/...)
depends on this setting.
LyX has help files in several languages. When you open a help file, LyX
tries to find a file for the configured language, and falls back to the
english set if there is no help. That is why you see some German and
some English help files. Your LyX is set up to look for German help,
probably because the OS is set to display German.
The help file language can be overridden too. It is not the above
mentioned LANG variable (or the preferences) that decide the help file
language. It is the LANGUAGE variable. I am not sure why this is so. A
reason may be that LANG is set to one language, while LANGUAGE is a list
of several languages in order of preference. In my case,
LANGUAGE=nb_NO:nb:no_NO:no:nn_NO:nn. This allow several forms of
Norwegian, as well as the oldfashioned "no_NO" that some not so
up-to-date applications still uses.
Many uses the LANGUAGE setting so apps will fall back to other languages
than english, if the preferred language is not supported. So someone who
prefer German first and French second, might set LANG to de_DE and
LANGUAGES to de:fr
You can change your OS settings to English, if you don't want to see any
German. Or you can override the LANGUAGE variable when starting LyX this
way:
LANGUAGE=C lyx
LyX will then show you english-language help files. You can set LANG to
C too, but it is not necessary when you override the language in the
preferences. If you don't like to start LyX from a command line, create
a script/batch file and arrange for your OS to start that.
