We had a long discussion about this with Igor, and at the time he was guarding Announcements, so nothing was integrated. Announcement improvement. ok we should have this discussion in the Pharo list. The postCopy and other code could move up. >>> Of course generic infrastructures have a cost. Now, before considering the cost of generic solutions, we should also compare it with the cost of maintaining 1000s of concrete use cases (such as inspector extensions). As you know, finding the right abstraction is difficult. For example, Traits underwent several implementations over 15 years, and now we have another one. You have a similar issue with Spec. For me, this is actually great. All of these served a purpose at the time, but the important part is that they were shipped even if they were not perfect. I think that this is important to have a simplification phase after a complex one. > I do not understand this part. Beacon was moved under the Pharo umbrella, but its integration was postponed multiple times due to various other external reasons in Pharo that were not under my control. Now, Beacon also came with documentation, and its implementation is smaller and has less concepts than SystemLogger (the main engine has 303 lines of code). I would be very happy to push it, but I do not know what else to do right now :(. Beacon use. I will read the code. And ask other people to do the same.

I think there is a confusion, so I added a comment for that: >>> https://github.com/moosetechnology/Moose/issues/1180#issuecomment-373904295 >> >> Yes but not only. >> You see when we introduced Glamour in Pharo.

The design is overly complex. > > We invested in the memory leaks as well. But, I think it would be a pity to say that the investment in GT had only costs and no benefits :). This is not what I’m saying but we should take care because you know like me that legacy after a while smashes you. >> What we introduce in Pharo should be maintainable by the majority. >> - method comments (look at Glamour not a single method comment!!!!!!!!!) >> - decent class comments and not just plain shit “this class is abstract” >> - tests and not with a super funky system that only one guy understand >> - less use of Pragmas >> - You see if >> I use Statespecs and >> you use GTExample and > >> denis use his testing framework because it is cooler >> then >> when we improve SUnit (which we will do) then fewer components benefit from it >> we have to pay attention to Statespecs, GTExample,….. instead of ONE framework. >> > > I do agree that one framework is important. Now, SUnit is around since decades and did not really change much so I do not think it would be such a bad thing to revisit its usage. We are planning this. (even if people will cry and complain that we are touching graal code). > GTExample is not only SUnit replacement, but also a way to document and communicate. I would be very happy to have a conversation about it. When I wanted to talk about examples a couple of years ago, there was not much interest for it. So, we went on to do our homework and now have significant case studies that drove significant projects, and now we can have that conversation with more concrete facts around us. You know what I mean and it depends. >> I think that Pharo will get a lot more picky about its components. So We are talking about Pharo 8.0 >> so you can be prepared.

The cool thing with Pharo getting more modular is that now the cost of people trying things out is smaller so this should raise more interesting debates, which I think is a healthy thing. > > >> I really think that Pharo 8.0 will be about massive cleaning up. >> So as a community we will have to have a real discussion about Pharo 80 >> because we will raise the bar and I will push all my voice for that because we cannot continue >> like that. >> I think that we should set some basic rules such as the tools we want for Pharo development and the quality rules. > > I agree. > > Doru > > >> >> Stef >> >> >>> Cheers, >>> Doru >>> >>> >>>> On Mar 17, 2018, at 6:39 PM, Stéphane Ducasse <stephane.ducasse(a)inria.fr&gt; wrote: >>>> >>>> I would like also to see what is the vision for the future of Moose. >>>> >>>> Because we will put some effort on the table but not blindly and I would like to avoid to >>>> throw away months of work. >>>> >>>> I would like to know what is the status of Glamour development because iceberg shows that Glamour is buggy. >>>> We also have memory leaks in Pharo because of GT tools and this is super annoying. >>>> >>>> I think that there are too many announcers to my personal taste >>>> >>>> stef >>>> >>>>> On 17 Mar 2018, at 18:26, Stéphane Ducasse <stephane.ducasse(a)inria.fr&gt; wrote: >>>>> >>>>>> >>>>>> On 17 Mar 2018, at 17:42, Tudor Girba <tudor(a)tudorgirba.com&gt; wrote: >>>>>> >>>>>> Excellent! >>>>>> >>>>>> Andrei and I allocated next Tuesday to look into migrating the code to GitHub.
