Thanks. Any code review or comments are welcomed. No interface now between fossil and grafoscopio. I just put all my STON files there, but STON + fossil is a combination you could consider also.

Re: [Pharo-users] Updated Pharo By Example

by Dimitris Chloupis

"Yes we can ask oscar and after will host it also at books.pharo.org and in HTML version too as for all the other books. Damien P and Damien C are working on a better latex template for pillar generated books." great to hear, I think not just UPBE but the other books need to be the first thing a newcomer sees when he or she introduced into Pharo because I think Pharo documentation is far better today that it used to be 2 years ago and we need to show the people all the hard work we have done with it. "pay attention. I think that we should minimize UI elements and external frameworks because else we will have more work in 4 years from now. " What do you mean ? As you know I am a supporter of pharo modularity but I fail to see how that is related to UPBE and I dont think documenting external frameworks is the focus of UPBE anyway just document what there is in the pharo image by default at least the core stuff that an average user is most likely to use. By any forms of tutorials and articles I did not mean that I will cram those in UPBE, if they refer to external third party libraries then I will document them in another book. But I was referring to tutorials and articles concering things that are part of the pharo image and they are beginner orientated. For example I am looking at documentation about code critics, update to the pharo catalog docs, Versionner , Kommiter etc On Fri, Oct 16, 2015 at 2:11 PM stepharo <stepharo(a)free.fr> wrote: > > > Le 15/10/15 18:12, Dimitris Chloupis a Ã©crit : > > thanks guys > > I can compromise for the time being with the user not going to the website > , searching for doc and founding documentation for pharo 1.4 while the > version he/she has is pharo 5 when we already have a book that is fairly up > to date. > > Is there anyone responsible for the PBE website ?

CiteZen and Pharo 5 / Pharo4 tests

by Peter UhnÃ¡k

Hi, I wanted to use CiteZen, but there's no Pharo 5 version (wouldn't even load), so I tried Pharo 4 instead but the tests are not passing: all CZBibTest fail on MessageNotUnderstood: Metaclass>>allMethodsInCategory: is this known problem? Do I need to use a very specific build of Pharo 4? Thanks, Peter
