Re: [Pharo-dev] chunk file format (unrecoverable changes)

by stepharo

Hi Eliot Thanks for the discussion. I will archive it and reread it. Now I think that historically they missed several points I learned while working on the Moose file format: - having doit or expressions to be executed instead of a declaration puts the burden on the tools. - for example not having a class definition declaration and just a do it forces the tools to parse and guess. - relying on sequence is not good because if you file is cut then this impacts several entities instead of having just one impacted. - I do not get why each entity in the chunk format is not self contained because in any case no decent programmer would use it to write code. - Mixing annotation and essential information makes the format really verbose. - what we see is that if we want to exchange on mail about code in several method in different classes, the chunk format is a pain vs. Point >> signature [ code here ] - This is not by accident that in all the books we wrote we use Clas >> signature code This way is not good because we do not have the warranty that code is not cut. Hence the previous one is better. I will restart one of these days to work on an alternate file format for textual editor. I do not like the GNUSt syntax. Now indeed how to store metadata is a good question. Stef

During the lecture I saw that {(10@20) . (30@40)} is printed as {(10@20). (30@40)} and I think that it would much nicer to have {(10@20) . (30@40)}

Some news from the growing pharo teacher front

by stepharo

Hi guys I want to let you know that there will be a new pharo lecture in YaoundÃ©. I presented Pharo during a seminar and the previous minister of education was there and asked us to do a lecture. In June we did it with Damien C. by skype. And now there is an official lecture at YaoundÃ© given by Prof. Metalagia. This is an excellent news. I will give some lectures in december there. In Togo my first visit was quite successful: 120 participants to the conferences I gave (it was still vacation time there). There were 60 students following lectures from 8h to 17h during 4 days... Yes I'm exhausted ;) A new Pharo lecture will start in north Togo. I will go back in December. One of the idea is to help students to get good in Pharo and pharo web stack and build web apps and other. I hope that we can have within 2/3 year There is a competition AppTogo. People are learning C# and others. I hope that some students will compete with Pharo so I will be looking for potential mentors to help them. Giving them advices, pointing them to the right solution/framework and may be a bit of pair rogramming if skype works. I distributed the Pharo Starter Kit (we will announce it officially now that I have 10 gb space on my server) People love the Youtube videos folder I'm collecting. Yes internet is a pain there. Chloupis I put your great youtube tutorial! Thanks for it. some students watched it. Stef

Indeed. With '-2' being the literal, its a consideration of whether whitespace is allowed within a literal. Otherwise '1 - - 1' should evaluate to 2 ?? Currently it errors, which seems correct.
