# devshell
|
||
|
|
|
||
|
|
A simple tool for spawning a `nix-shell` with certain packages in the `LD_LIBRARY_PATH`. Useful for experimenting with runtime-loaded dependencies.

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.
