Interesting to see this is the top mentioned book on stackoverflow. I wonder if Moose can facilitate any of its contained topics and maybe leverage its popularity. </randomThoughForTheDay> cheers -ben

Hi Ben, Chapter 16 "I Don´t Understand the Code Well Enough to Change It". Michael C. Feathers proposes sketching to understand the code better. Moose allows it to automatize and improve this manual work. But before a sketch can be drawn the code has to be analyzed. And a sketch has to be adapted if the code changes. Moose allows to automatize this. You can generate diagrams automatically. My impression is, that I still needed an application on top of Moose to make smaller diagrams that describe a certain aspect of a coding. I needed some way to limit the number of elements displayed, specify their positions and add comments to them. I do this currently in a Smalltalk application I developed on top of Moose and Roassal. It is NOT only for SAP applications as might seem. The Github Repository that links to the Smalltalkhub page: https://github.com/RainerWinkler/Moose-Diagram I made a short video to show I am currently using Moose and this application to work with this kind of sketches. Even though it is an early version, I use it near to every day in my projects: https://drive.google.com/drive/folders/0B0BTdgDL6XSLeHB4aTZxTkdSNXc Cheers, Rainer -----Original-Nachricht----- Von: "Ben Coman" <btc(a)openinworld.com> An: "Moose-related development" <moose-dev(a)list.inf.unibe.ch> Datum: 02/14/17 13:16 Betreff: [Moose-dev] Book, Working Effectively with Legacy Code Interesting to see this is the top mentioned book on stackoverflow.

Nice work! Is the SAP exporter available? I'm actually not familiar with programming SAP. I'm just a user of it, but with it maybe I could lead others in the company to try Pharo. cheers -ben On Tue, Feb 14, 2017 at 9:15 PM, <rainer.winkler(a)poaceae.de> wrote:

Hi Ben, the SAP exporter is available. I did not add a link to prevent the misunderstanding that the other tool is specific for SAP. You can download it from from https://github.com/RainerWinkler/Moose-FAMIX-SAP-Extractor It is not finished, please see the issues list. I am currently adapting the core logic to have better tests. This part of the work is currently not shared as the main development is done with global classes, and I do not yet use ABAPGit (https://github.com/larshp/abapGit) to share this. I will add more object types in the next weeks. Cheers, Rainer PS: As I use both tools together, they have a tendency to become somehow connected. I am for instance currently mapping all SAP elements to FAMIX package, class, method and attribute. This makes the work in the other tool easier. I add modifiers if needed to specify. -----Original-Nachricht-----

Thanks Reiner, When I click the link, I'm asked to choose a Google account. There is any way to see the video without a Google account? (some of us still think that Big Brother Marketing (TM ;-) ) is undesirable). Cheers, Offray On 14/02/17 07:50, rainer.winkler(a)poaceae.de wrote:
