Review

Before we continue into more advanced subjects, let's stop for a moment and review. What have we gained here? First of all, we have standardized where our binary builds are defined for our repository: /nix/example/apps.nix. If we want to add additional builds (i.e., a debug binary), we know exactly where to put it. As a bonus, we don't even need to worry about the system fiasco that flakes are often criticized for.

Secondly, we have standardized what most of our Nix code "looks" like. The {inputs, cell} format is deceptively powerful. One of the most significant sources of complexity in large Nix codebases stems from the question, "How do I access everything?" In our case:

• Inputs can be accessed via inputs
• Anything within our local cell can be accessed via cell
• Other cells can be accessed via inputs.cells

Meaning that as long as we adhere to the organizational principles being applied with std, we don't have to worry about figuring out where to put things and how to access them.
