neovim no longer obeys LANG

Ypixcm · 2024-07-22 11:29:33

The output of my echo $LANG in the terminal is zh_CN.UTF8, and the program interface of vim and nano normally displays Chinese (zh_CN.utf8), but neovim does not seem to comply with it，neovim is still in English，I can fix this by manually setting "lang", but is this a bug？

what do `locale` and `locale -a` give you?

Shouldnt it rather be "zh_CN.UTF-8", like it is set in https://wiki.archlinux.org/title/Instal … calization?

I'm sorry I misspelled it.It's “zh_CN.UTF-8”.

locale :

cm@thinkpad ~> locale
LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY="zh_CN.UTF-8"
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER="zh_CN.UTF-8"
LC_NAME="zh_CN.UTF-8"
LC_ADDRESS="zh_CN.UTF-8"
LC_TELEPHONE="zh_CN.UTF-8"
LC_MEASUREMENT="zh_CN.UTF-8"
LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=

locale -a :

cm@thinkpad ~> locale -a
C
C.utf8
en_US.utf8
POSIX
zh_CN.utf8

I found that when my /etc/locale.conf is 'LANG=en_US.UTF-8', neovim is always in English

(on the contrary, when /etc/locale.conf is 'LANG=zh_CN.UTF-8', neovim is in Chinese)

but I want to make a point that Chinese characters can't be shown in agetty
https://wiki.archlinux.org/title/Locali … ed_Chinese :

Warning: Globally setting Chinese locales in /etc/locale.conf will cause tty to display garbled texts due to the tty glyph limitation of Linux kernel. To properly display Chinese characters under tty, you need to set the tty glyph limitation in the Linux kernel.

We have a solution.:
https://wiki.archlinux.org/title/Locali … interfaces
With this method, my xfce,nano,vim.......'s will use Chinese,But neovim is the only thing that doesn't work.

cm@thinkpad ~> echo $LANG
zh_CN.UTF-8
cm@thinkpad ~> cat /etc/locale.conf
LANG=en_US.UTF-8

I may have found the problem

cat .xprofile
export LANG=zh_CN.UTF-8
export LANGUAGE=zh_CN:en_US

After I deleted "export LANGUAGE=zh_CN:en_US", Neovim would display the Chinese interface

https://wiki.archlinux.org/title/Locale … ck_locales :

Note: Many applications do not name or alias their English locale as en or en_US, but instead make it the default locale, which is C. If in LANGUAGE a non-English locale is placed after English, e.g. LANGUAGE=en_US:en:es_ES, then applications may choose the secondary locale despite English strings being available.[3] The solution is to always explicitly place the C locale after English. E.g. LANGUAGE=en_US:en:C:es_ES.

LANGUAGE defines a fallback cascade, it'll try zh_CN first and resort to en_US then
Why are you controlling the locale in .xprofile if you're mostly concerned about the console?
Edit: scratch that

stat /usr/share/locale/zh_CN.UTF-8/LC_MESSAGES/nvim.mo
# /w LANGUAGE=zh_CN:en_US exported:
strace -o /tmp/neovim.strace # quit neovim
cat /tmp/neovim.strace | curl -F 'file=@-' 0x0.st

I found that neovim only had the zh_CN.UTF-8.po translation file, but no zh_CN.po

So I only need to change export LANGUAGE=zh_CN:en_US to：

“zh_CN.UTF-8.po” is wrong, it should not carry the encoding ‘UTF-8’.
https://github.com/neovim/neovim/blob/m … N.UTF-8.po
https://github.com/neovim/neovim/blob/m … W.UTF-8.po

strace -o /tmp/neovim.strace neovim

Do NOT "set LANG C" for this, we want to know what happens when nevim fails to use chinese.

The LANGUAGE variable isn't supposed to use those variants, "zh_CN" should™ do.
I'm not sure this has actually fixed anything.

@seth thank you
I've figured out that it's actually a Neovim bug.
“zh_CN.UTF-8.po” is wrong, it should not carry the encoding ‘UTF-8’.
https://github.com/neovim/neovim/blob/m … N.UTF-8.po
https://github.com/neovim/neovim/blob/m … W.UTF-8.po
The right name:
zh_CN.op
zh_TW.op
