The generated user activation script is broken when NIX_PATH contains paths with spaces in them due to the spaces not being escaped.
The motivation for this fix is that I've set
use-xdg-base-directories
totrue
while also customizing theXDG_*_HOME
variables to try and follow macOS conventions (i.e.XDG_CONFIG_HOME
is~/Library/Application Support
, hence the issue with spaces in the path). I then set one of the paths innix.nixPath
to$HOME/Library/Application Support/nix/defexpr/channels
which causes the user activation script for switching to a new generation to break.
