This project was started to allow loading nix shell without leaving your current shell. Inspired by direnv https://github.com/direnv/direnv.
Under the hood it will run nix-shell --show-trace --run "env". It will compute a diff between your current env state and output nix env. Finally it will output a script that is ready for evaluting in your current shell.
go get -u github.com/atrzaska/use_nix
To load nix shell of your project make sure you have properly setup nix on your system and shell.nix on your project. After that you can run:
eval $(use_nix)
This command will evaluate your shell.nix and setup your enviornment variables in your current shell.
