Re: [Pharo-dev] control flow graph

by ClÃ©ment Bera

I used that in the past on intermediate representations, I feel it is very useful to directly edit the code of methods with large control flows since when you have many closing brackets ] ] ] ] you never know where to write your code. Now it's specific to some use-cases such as algorithms where you write methods with large control flows, in most methods due to object oriented programming convention the control flow is not that big. In this context other things could be possible (Smart suggestions to move code out of loops, etc.) On Fri, Feb 23, 2018 at 11:37 AM, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: > Hi > > I'm experimenting in building a control flow graph of pharo methods > and I would like to know if you have ideas about what we can do > with them to support our development environment. > > Stef > > -- ClÃ©ment BÃ©ra Pharo consortium engineer https://clementbera.wordpress.com/ BÃ¢timent B 40, avenue Halley 59650 Villeneuve d'Ascq

control flow graph

by Stephane Ducasse

Hi I'm experimenting in building a control flow graph of pharo methods and I would like to know if you have ideas about what we can do with them to support our development environment. Stef

OBS should work, the process is in place. This effort got killed slightly because it was not possible to get the current vm sources in a shape you can feed into a process. First it was that pharo-vm was different to opensmalltalk-vm. Now I do not remember but there is still a problem. Esteban can tell. For me this is sad because the way the vm is implemented and managed it seems neither easy to collaborate nor easy to consume the result. And that is needed if you need to feed that in a process like linux packaging. I find this really important, I even spend money on it to be done. Butâ¦. we will see. I know Holger will care to update OBS if the process allows him to do. But he got stuck every single time he tried to do it. For the choice of linux this is either business or religion dependent. If you need professional support for the linux you should choose one of the big ones, I think this is ubuntu or redhat. They all have long term support versions so you donât need to follow the crowd every day. If you need to have multiple different pharos on your machine you might need to go virtual. Having pharo encapsulated in a docker image feels natural and you can be sure that system-wise you can pharo4, pharo5-32bits, pharo6-32bits, pharo6-64bits all in parallel without disturbance. Basically you need not much more than this Dockerfile <snip> # # Pharo6 Dockerfile # FROM ubuntu:16.04 # Add opensuse repository and install pharo6 binary from there RUN \ apt-get update && \ apt-get install -y wget curl unzip inetutils-ping && \ wget -q http://download.opensuse.org/repositories/devel:/languages:/pharo:/stable/x… -O- | apt-key add - && \ echo 'deb http://download.opensuse.org/repositories/devel:/languages:/pharo:/stable/x… ./' > /etc/apt/sources.list.d/pharo6.list && \ dpkg --add-architecture i386 && \ apt-get update && \ apt-get install -y pharo6-32 pharo6-sources-files && \ rm -rf /var/lib/apt/lists/* RUN mkdir -p /pharo-vm/32 \ && cd /pharo-vm/32 \ && curl get.pharo.org/vm70 | bash </snip> It creates a pharo docker image (mine is called pharo6-32) with the OBS linux vm installed and the pharo7 vm downloaded so you can try which one is better. Applications with pharo I do with this <snip> FROM pharo6-32 RUN apt-get update && apt-get install -y curl COPY Project.image start.st /opt/ # Define working directory. WORKDIR /opt # Define default command. #CMD "/usr/bin/pharo6-32" "--mmap" "64m" "/opt/Project.image" "--no-default-preferences" "st" "/opt/start.st" CMD "/pharo-vm/32/pharo" "--mmap" "64m" "/opt/Project.image" "--no-default-preferences" "st" "/opt/start.st" EXPOSE 3000 </snip> So if you have the pharo image as Project.image in the same directory as the Dockerfile then this image is copied into the docker image and when you start it is called. Hope this helps, Norbert

Ubuntu Server 16.04.3 LTS https://www.ubuntu.com/download/server Most used, best supported, stable. I know not everybody will agree, and that is fine. There are 100s if not 1000s of Linux distros out there. Unless you know very well what you are doing and why, this is the safe choice. Else you can end up on your own, we can't support them all, and you won't find any other users willing to help you. Sven

Re: [Pharo-dev] Linux installation

by Stephane Ducasse

Hi sean Yes we should. Now I think that the community does not really realise how much work it is to produce Pharo. And we cannot and will not do everything. At the end of the day, if pharoers are not able to give 30 min of their time to improve then it will stay like that. I mean if marcus, me and other spent time reviewing, fixing typos on the web then it means that object-centric debugger will not show up. You see we have only a limited amount of resources. So this is good to see all these wishes and needs. I have plenty of them too. But at the end of the day when we do the check if pharoers do not contribute then we will have less done. This is as simple as that. Stef On Fri, Feb 23, 2018 at 5:41 AM, Sean P.
