About asSymbol message , some questions in my mind
by lb Feb. 11, 2017

Feb. 11, 2017

Hi, I know Symbol is subclass of String. Any string object can become symbol object by sending 'asSymbol' message.. I think symbol must has its meaning in comon use, so the symbol should be composed of alphabet or number âwithout spaceâ. BUT There are not compliant below 1. ' ' asSymbol >>>> no meaning 2. '$%%&' asSymbol >>>> no meaning 3. 'sign' asSymbol = 'sign ' asSymbol >>> false because of space. 3. ' one two three ' asSymbol >>> I think It should become three symbols = #one, #two, #three Maybe my understanding is wrong. Bing Liang

Final rush for submitting GSOC proposal - Need your help
by Serge Stinckwich Feb. 10, 2017

Feb. 10, 2017

Hi all, we are currently working with Alexandre to submit the gsoc proposal to Google. I was a little bit busy with my lectures and I didn't check the current proposals available here: http://gsoc.pharo.org/ but all the projects are coming from RMOD team, but having all the projects proposal coming from the same place might be perceived negatively from Google. Can we add more projects from previous gsoc form other people also ? We have only one hour to polish the list. Thank you for your help. -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

[Teapot and Voyage] sending over the voyageId
by sergio ruiz Feb. 10, 2017

Feb. 10, 2017

I am working on the U of the CRUD part of my Teapot/Voyage REST interface, and found that I cannot get the voyageId to be delivered as part of the REST response.. in order to do RUD, I will need that in the feed. the problem is that NeoJSON uses the instance variables to JSON encode the object. to circumvent this, i made an instance variable called âidâ.. and made an accessor like so: id ^ self voyageId value so i can do something like station id -> â23434234234243423432â but when i inspect the object, or send it back from voyage, id is nil.. rather than mirror voyageâs _id, i would like access to it in JSON encoding, but i can see that might be a problem.. any ideas? thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Pharo Object Model
by Oleksandr Zaytsev Feb. 10, 2017

Feb. 10, 2017

Hello, I'm trying to understand the logic behind The Pharo Object Model. Rule 3 states that every class in Pharo has a subclass. I was expecting some cool loop, like in the case of Metaclass, which is an instance and also a class of Metaclass class. But ProtoObject, which is the root of an inheritance hierarchy does not seem to have a superclass (ProtoObject superclass answers nil, which is not a class). Does this mean that Pharo Object Model is inconsistent? Is ProtoObject an exception of the third rule? If you think about it, an inheritance hierarchy can't have a loop, because otherwise, when looking for a nonexistent method in superclasses, Pharo would be stuck in that loop. So why is there even a loop in instance hierarchy (Metaclass class)? Does it have a purpose, or is it there only to satisfy the second rule of the Object Model? Because if the consistency of third rule can not be satisfied, wouldn't it be better to add two exceptions to the model? Please correct me if my understanding or reasoning is wrong. Thanks!

Dear all, thanks to the efforts of Jigyasa Grover, Yuriy Tymchuk and Alexandre Bergel, , we were able to have a GSOC 2017 application for the Pharo Consortium. This is only the first phase. If we are selected by Google, they will give some slots for students. We have a list of projects for GSOC here : http://gsoc.pharo.org/ If you have more ideas, please send them to me or send a PR on : https://github.com/pharo-project/pharo-project-proposals/blob/master/Topics… Try to describe your project idea with 10-15 lines maximum. The ideas is not too much projects proposals but to find important projects for the Pharo community (i.e that will have some impact for the community) with the support of the appropriate mentors. I would like to have maximum 2-3 projects for each mentors. Thank you.

Re: [Pharo-users] Problem in installing Pharo â Solved thanks to you

Thanks for the followup. Great to hear its working. Just a minor one thing. Can you see if your email client has a "Text Only" send feature that can apply to the mail list? Your font ends up too large & bold here (its nice to have all the mails a standard size), and some of the list archiving software interacts badly with formatted text. Hope you have fun with Pharo and we see you back on the list with more questions soon. cheers -ben On Fri, Feb 10, 2017 at 6:59 AM, Mark Neagu <mark(a)mneagu.fr> wrote: > Hi! > > Several nice persons mailed me to help: Sven, Dimitris, Ben, Nicole. > > Now everything works fine and I'm studying the tutorial. > > You people are really helpful and there is no doubt the PHARO language is > promised to a briliant future thanks to its qualities and to your dedication > at making it work. > > Best regards, > > Mark

[Pharo-user] Does SSDP package supposed to work on Pharo 6?
by Denis Kudriashov Feb. 9, 2017

Feb. 9, 2017

Hi. Question probably to Henrik. I try SSDP <http://smalltalkhub.com/#!/~henriksp/SSDP> on latest Pharo 6 and code for server and client signal primitive error on #primGetAddressInfoHost:service:flags:family:type:protocol:. Do you know about such problems? Does it VM or code needs to be adapted for Pharo6?
