This oh-my-zsh plugin lets you use zsh as the default shell in a nix-shell environment. It's recommended to use this in conjunction with nix-zsh-completions.

In theory all you have to do to get this behavior is set NIX_BUILD_SHELL to zsh. Unfortunatly nix assumes that the NIX_BUILD_SHELL is a bash variant and passes bash specific arguments to the shell. So we need a shim to be able to process these arguments.

If you use the --run argument to execute something inside the nix-shell and then return it will still be run using bash since we only need zsh for interactive shells.

git clone [email protected]:chisui/zsh-nix-shell.git ~/.oh-my-zsh/custom/plugins/nix-shell

Then add nix-shell to the plugins list in ~/.zshrc.

Clone this repository and add the following to your ~/.zshrc.

source /path/to/zsh-nix-shell/nix-shell.plugin.zsh
