nix-shell sets unsets LANG and friends #318
Description
In nix-shell
LANG=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=
outside of nix-shell
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
This causes problems when we drop into a shell to hack on a project that expects reasonable LANG settings, such as GHC test-suite:
WarnMinimal.hs:92:1: Warning:
The MINIMAL pragma does not require:
- ‘cheater3b’
+ `cheater3b'
but there is no default implementation.
- In the class declaration for ‘Cheater3’
+ In the class declaration for `Cheater3'
I thought there was an issue open for this somewhere already but I could not find one.
