Voyage and instances retrieving
by Hilaire March 7, 2017

March 7, 2017

Hi, When iterating, with Smalltalk selectors, an object persisted in a repository, some of its attributes (I guess because root for other collection) are not resolved as expected at iteration. The Smalltalk iteration does not work, returning empty result. Fetching the whole model in memory will be an acceptable option. Is there a global way to do this? I see the per attribute beEager but it will be needed for a lot of attributes making not practical. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Pharo Association
by Jimmie Houchin March 7, 2017

March 7, 2017

Hello, I am looking into the Pharo Association. I looked at the Contribute page, http://pharo.org/contribute and saw the links to BountySource. One of them had $9 monthly being a Gold Membership Pharo Association. I do not see this as an option if you do Join on the Pharo Association Join Us page, https://association.pharo.org/join-us . I do not know which option is most favorable for or least expensive to the Pharo Association. I also do not see what payment methods are available on the Pharo Association pages. BountySource I know my options. From the BountySource page I do not know how this connects me to the PharoAssociation. If all things are equal, I would assume do BountySource, I can start a monthly cash flow immediately. It would also be nice to know if doing BountySource that is always an option to levels other than the set levels but you only get the benefits of the highest level you contribute at. For example if I wanted to do $15 a month instead of $9, or even a simply $10 instead of $9. or .... I think this could be by instead of saying $9 a month, express it as minimum of $9 a month. Or what is appropriate for each level. If BountySource is more expensive on the Association's end. I would prefer to do whatever payment options are on the Association site. But it would be nice to know what those are before I begin to complete the forms. Thanks for any information on the process so that I can begin to contribute to Pharo. Jimmie Houchin

MOOC english subtitles
by Ben Coman March 7, 2017

March 7, 2017

May I do a pass over the english subtitles for the MOOC? With the limited space and reading time you get with subtitles, I see some things I could fine-tune. One query on content, from [1] it says there are "good comments" when I'd guess it would say "poor comments" from there being no class comment 16 00:00:49,830 --> 00:00:51,920 The system searches a little and says that there are 17 00:00:53,200 --> 00:00:56,290 good comments. We will see this later. For the moment, we donât care. cheers -ben [1] https://github.com/SquareBracketAssociates/PharoMooc/blob/master/Subtitles/…

why is concat of Symbols a string?
by Peter Uhnak March 6, 2017

March 6, 2017

Hi, why is the concatenation of symbols a string? e.g. #desc, #Name -> 'descName' this means that I have to always wrap in parentheses and recast, or stream it, e.g. (#desc, #Name) asSymbol -> #descName Symbol streamContents: [ :s | s << #desc; << #Name ] -> #descName both of which introduce extraneous syntactical clutter. The technical reason seems to be ByteSymbol>>#species returning ByteString, but I have no idea why it has to be this complicated. Thanks, Peter

It sounds like the changes file for your image is missing. Could that be possible?

Now what you should know is that - i would use this mechanism for debugging/tooling - i would try to avoid this as much as possible for domain modeling because it breaks all the hidden assumptions we have. stef Hi Steven . For the moment i just want to understand how it is possible. In the future may be i can apply this mechanism for future projects. Pablo Ing.

Voyage and duplicated entry
by Hilaire March 6, 2017

March 6, 2017

Hi, I have strange behavior when saving object: when I edit then save, I got a duplicated entry in the repository collection. Some description about the object: This object class is part of a hierarchy class, where the top is defined as voyage root. In this object, hash and = are redefined. Any pointer?
