[Grok-dev] megrok.rdb

All the packages have READMEs and tests.
But yes... Most of the work was done by myself and given the amount of work
needed in the code, the documentation always came last sadly.
Given the lack of interest initially for the project in the community, It
failed to gain more attention from people

Cromlech uses some ZTK packages, if they are detached enough from the whole
stack. The idea is to have something you build from bricks, one at a time,
not to start with more code than you can understand.
Having a complete understanding from the request creation to the final
response was key to produce quick and quality code, for problematics I
could never resolve with Grok itself.
Having less overhead and more direct compatibility with generic python
packages (base WSGI ones especially) is very appreciable.
It's incredibly satisfying to be able to intervene at the right level in
the stack, when you need it, without having to rely on a ton of adapters,
events and subscriptions.

Historically, the starting point was to remove zope.publisher. It's so
entangled in the rest that we ended up stripping down everything, piece by
piece.
Martijn and myself coded "dawnlight", that is the base publisher here and
Crom/Grokker to use Venusian and more a flexible registration system for
components.
These ideas were at the base of Morepath, I took a more grokkish approach
with Cromlech.

Finally, a lot of effort was put into making the "framework" agnostic,
regarding the DB and the request/response objects.
The security system is very light and flexible, allowing a very simple
security or a very complex one.

In term of productivity, it's very hard to assess.
What I can definitly say is that we gained a lot of flexibility while
stripping down the base code to a minimal.
It's faster, easier to maintain, easier to understand and is a solid base
to build on.
Too often, Grok/Zope2/Plone feels like you're fighting against it or
bending it to fit your needs.
I think it's profitable to actually code what you need, starting from a
simple base instead of having to deal with a lot of decisions already made
for you that may cripple your project.

i hope I make sense in this mail. I can sound confusing as it's difficult
to summarize years of decisions, code and try to sparkle an interest at the
same time.
There is a simple demo here : https://github.com/Cromlech/CromlechCromDemo,
that does a few things.
It's interesting to dissect the anatomy of an application, here :
https://github.com/Cromlech/CromlechCromDemo/blob/master/src/cromdemo/src/cromdemo/wsgi.py
The focus of my work was to have concise, fast and explicit code , i hope
it speaks for itself.

Thank you for your interest so far.
