There are foundational aspects on knowing a component is done, that it will be the same everywhere. What do you think of Nix [1]? The other quality of flexible composable systems is that they can be extended with something akin to an AoP system. Non-essential qualities can be woven and applied during composition so that each component doesn't have to implement various features. A counter example is the find command, it has to implement a predicate language into the tool itself. If it omitted typed objects, a filter engine could select the subset. If find implemented polymorphic values, the predicate would dictate what facets were populated in the structures themselves but our shells don't work that way. A metashell that could define its environment and the streams of structures flowing between components could get us closer to a pervasively composable mode of system construction. Unix pipelines [2] are awesome, but they aren't the pinnacle. I feel like all of us fall short in creating systems that compose. Most (scalable) systems should be fractal, while most composition is limited to a narrow first-order mode of operation. [1] https://nixos.org/ [2] https://en.wikipedia.org/wiki/Douglas_McIlroy |
