Hi Guixers,

somebody wrote to me to do a:

export LC_ALL=C

to get the output in English, because I am using German.

Unfortunatelly I lost this email.


1.  Will this now overwrite my variables for ever, or only for some time?

2.  How can I set it back to my original state?

thanks for help

Gottfried

Hi Gottfried,

I hope this strikes the right balance between explaining 
‘environment variables’ from scratch and answering your immediate 
question.

Environment variables are not saved.  They can be *set* by 
configuration files, such at /etc/profile, but these files are not 
updated when you type ‘export GUIX=awesome’ on the command line.

Setting LC_ALL like this affects your current shell, and it will 
be inherited by child processes (hence why the ‘guix’ child will 
speak English after setting LC_ALL=C in the parent shell), but 
they exist purely in RAM for the lifetime of each process.

The also do not propagate to ancestor or sibling processes: 
setting LC_ALL in one terminal window has no effect on any other 
windows.  Nor will setting LC_ALL in a shell affect new processes 
you launch elsewhere, such as from your desktop menu.  Only child 
processes launched in the same shell/window will inherit it.

As soon as you close that terminal, type ‘exit’ in the (guix) 
shell, or trip over your power cable, the setting is gone.

> 2.  How can I set it back to my original state?

Environment variables have no built-in notion of history, or 
defaults.  They are just variables, and setting them to something 
new overwrites the old value (if any).

So:

~$ echo $LC_ALL		# yours will be de_DE, I presume
en_IE.utf8
~$ LC_OLD=$LC_ALL	# save the old value
~$ export LC_ALL=C	# in with the new
~$ echo $LC_ALL		# do the thing
C
~$ LC_ALL=$LC_OLD	# restore the old value

But really, in practice, I'd just close the window/shell once 
done…  they are so cheap.

Kind regards,

T G-R

What I do is set the LANG variable to C. For example, in a terminal, you'd run:

  LANG=C guix describe

And you'd get the output in English only for that command. If you run it again without the "LANG=C" part, you should see the output in German.

I see the value C as "the language or locale in which programs were originally written". In this case it is English because Guix is written in English.

You can use the same trick to use programs in any of the languages they are localized to. For example, the following prints the output in French:

  LANG=fr_FR.utf8 guix describe

To find out what kind of values you can pass to LANG, you can run the following command:

  locale --all

That command is provided by the package "gcc-toolchain".

Hope that helps,

I also think it's the clearest recommendation for someone new to
locales, but it may not adjust the order of months and days in dates
or other cultural conventions. LC_ALL changes all six categories
described here and is therefore often preferred, despite its weird
name.

Assuming it was posted to this mailing list, you can go to
https://lists.gnu.org/archive/html/help-guix/ and search for it by
some text the email contained.
