# Source Layout

The source tree maps to the DNS namespace that we own. The purpose of
this mapping is to keep things organized hierarchically in how they are
deployed on the Internet. The main 'common' space is `Com.Simatime`,
other namespaces should be related to the application.

Development aspects should be localized to their sub-namespaces as much
as possible. Only after sufficient iteration such that interfaces are
solidified and functionality is well-established should some code be
promoted up the namespace hierarchy.

Boundaries and interfaces between namespaces should be small and
well-defined. Likewise, the functionality and purpose of a particular
namespace should be small and well-defined. Following the unix principle
of "do one thing and do it well" is advised.

For building the code, we use `nix` and basically copy the namespace
hierarchy into the main build file `./default.nix`.

# Development

To build code, do:

    nix build -f default.nix <thing>

To get in the environment for a thing, use `nix run`. For example, if
you want `ghci` with packages for `ibb`, do this:

    nix run -f default.nix Com.InfluencedByBooks.ghc && ghci

And to deploy:

    nix copy --to ssh://root@simatime.com ./result
    ssh root@simatime.com $(realpath ./result)/bin/switch-to-configuration switch

These three common tasks are captured in the `./bild`, `./ghci`, and
`./push` scripts.

# Goals of the developer workflow:

- have minimal ceremony
- default to asynchrony, but allow for synchronous work when necessary
- automate the boring stuff
- standardize environments, tooling, and versions to minimize friction
  while collaborating
- support the longevity and self-sustainability of the project

Ideally, each contributor should be able to go off grid for a day or a
week or more, continue working offline, submit their work when finished,
and have no or minimal conflicts. This also refers to the resilience of
the production systems.

We should never need "out of office" email auto-replies, or urgent
contact. No pager duty, no daily stand-ups. Yes, this policy will affect
what code we write, not just how we write it; that is by design.
