RE: Hey - A Conceptual Simplication....

["George Dennie" <gdennie@pospeople.com>]

Thanks Jakub Narebski and Björn Steinbrink...Nice description Björn.

I think an important piece of conceptual information missing from the docs
is a concise list of the conceptual properties defining the context of the
working tree, index, and repository during normal use. This itemization
would go far in explaining the synergies between the various commands. 

Functionally, all the commands merely manipulate these properties. If these
properties were summarize in context one would expect that would represent a
very complete functional model of Git. A user could review the description
figure what they wanted to do and then find the command(s) to accomplish it.


Presently this knowledge is accreted over time as oppose to merely being
read and in the space of a few minutes "groked" (of course it could be that
I am particularly limited :).

For example, towards a functional model, is this close? (note: all
properties can be blank/empty)...

REPOSITORIES
	Collection of Commits
	Collection of Branches
		-- collection of commits without children
		-- as a result each commits either augments
		-- and existing branch or creates a new one
	Master Branch
		-- typically the publishable development history

INDEX
	Collections of Parent/Merge Commits
		-- the commit will use all these as its parent

	Staged Commit 
		-- these changes are shown relative to the working tree

	Default Branch
		-- the history the staged commit is suppose to augment

	Collection of Stashes
		-- these are not copies of the working tree since they
		-- only contain "versioned" files/folders and so is not
		-- a backup

WORKING_TREE
	Collection of Files and Folders
	

As far as I can tell, the working tree is not suppose to be stateful, but it
seems the commands treat it as such.

What is interesting is that branches serve to encourage a serialized view of
commits. More than structure, they are like books in a library narrating a
development story. Consequently, and interestingly, they are as much the
purpose of the repository as the commits they organize...which is
interesting.


Again, thanks for your patients.

George.
