Hi Uwe, The Git model is more finely divided for the preparation of the commits. It deliberately allows you to pick apart your prepared work (you may have tried a few things before being ready).
Often you will want to present the changes in a neat fine grained manner that takes a few commits to build the overall effect, each with distinct commit messages. I used it quite often with MatLab programming (which is an interpreted language, so lots of hack and hope), so I could pretend that I prepared the algorithm, then generated a neat result matrix and finally created the graphs. A similar situation can happen with scripts. So in Git, you can add 'everything', a few things, or even pick lines from files, for each commit, leaving the worktree (real filesystem content) distinct from the 'staging area/index' (equivalent to the old fashioned outbox on your desk-top ready to summon a clerk to 'file'[commit] it's contents). It's disadvantage is that most modern folks don't have the mental model or imagery in their heads to know what to do, and the Git documentation is very poor at describing these mental model things. e.g. https://www.thebalancecareers.com/thmb/XQAXfDC4f4p1YlCPBPxKoY-TVpc=/950x0/file-clerk-2164293-Final-4a26502d0c5c452684c3f13fe5f549aa.png On Wednesday, November 20, 2019 at 1:58:25 PM UTC, UWE RICHARD OTTO BRAUER wrote: > > Hi > > Am a frequent mercurial user, and an occasional git user.
