Biz.Dev is the namespace for business development (duh). Here we define the
tools and infrastructure for internal dev work.
# Goals of the 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.
# Getting started
Jump into a development shell:
nix-shell
Then run `help` to see the dev commands.
The source tree maps to the module namespace, and roughly follows the
Haskell namespace hierarchy (although nothing is enforced). The main
'common' space is `Biz`, other namespaces should be related to their
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`.
Namespaces are always capitalized. I would prefer always lowercase, but
`ghc` _really_ wants capitalized files, so we appeas `ghc`. In Scheme
this actually translates quite well and helps distinguish between types
and values.
File extensions denote _type_ and indicate to the build system how to
handle the file. So for example:
- `.hs` is Haskell source code, the build system compiles it
- `.scm` is Scheme source code, ditto
- `.org` is an organizational text document, the build system ignores
this, but we use them to make plans and such
- `.jnl` is a journal for accounting, the build system will check our
balances, make sure we're profitable
