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.

Additionally this plugin passes what packages are specified to the shell in NIX_SHELL_PACKAGES. The main purpose for this is so that they may be printed in the promt. Take a look at this variant of the agnoster theme for an example of how this might look.

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
