Installation

npm install -g nix-devshell

Usage:

$ devshell xorg.libX11 xorg.libXcursor xorg.libXxf86vm xorg.libxcb xorg.libXi
Spawning shell with packages [xorg.libX11, xorg.libXcursor, xorg.libXxf86vm, xorg.libxcb, xorg.libXi] in the LD_LIBRARY_PATH...
$ echo $LD_LIBRARY_PATH

The new entries are prepended to the LD_LIBRARY_PATH in the environment from which you ran devshell, so it won't break things like OpenGL. You can use the resulting shell in the exact same way as you'd use nix-shell; simply exit it to return to your 'real' shell.
