# Journal on development
This contains information dump to record thoughts as I design this repo
## Nix as first-class citizen instead of native config
- Nix can export JSON and other object serialization formats
- Still allows native config, so that Neovim, for example, which uses Turing-complete
config language, to make full use of its native LSP.
## Design pattern emerges from unstructured code
### Modules
- Main thing for the first big refactor of codebase
- nixpkgs and home-manager has their own interface for modules
- The main benefit is to provide (runtime) type-safety on options, along with
documentations and defaults
## Nitpicky details
### `nativeBuildInputs` vs `buildInputs`
- `nativeBuildInputs` is available **before** `buildInputs`.
- `nativeBuildInputs` is supposed to be built by a deployment machine (not target)
- `buildInputs` gives you access during runtime
- `nativeBulidInputs` gives you access to packages during build time
- `mkShell` doesn't care about `packages`, `nativeBuildInputs`, `buildInputs`
