Re: [Pharo-users] Crash in Athens

Hi Ronie, Esteban. Ronie's suggestion in the form Esteban presented it helped. After implementing the fix I failed to crash my application any more. Will anybody be so kind to explain me what actually happens and why the fix works? It looks so innocent. As far as I understand we do one

Re: [Pharo-users] why is concat of Symbols a string?

Hmm.. symbols is usually treated like immutable object(s) in system. They tend to stay while rest of data changes.. This could explain why authors of this method purposedly picked to use ByteString for its species to discourage using symbols for collection manipulation(s).. Else, if you would need

This may be overkill for your use but would love to have an MIT licensed set of classes that allow for/enable something like this: https://medium.com/assist/theres-a-dozen-ways-to-order-a-coffee-why-do-dumb-bots-only-allow-one-27230542636d#.laljhpyt5 sergio ruiz wrote > Hey all.. > > I got

Re: [Pharo-users] Voyage and Date

I would love to have a digest of the problems you encountered and the solution. Because like that we could write a better documentation. I cannot because I do not face the problems (since I'm not developing real apps for lack of time/concentration). Stef On Sat, 04 Mar 2017 12:15:39

Hi Olivier, You probably have a few of these references, but since you don't mention which you have, I'll list what I found from a quick sweep... I read [1] that the Firmata protocol "uses the MIDI message format." Pharo seems to have removed the MIDI related code after it forked from

Re: [Pharo-users] Voyage and Date

I think sticking to a date string is the safest thing to do. Especially if you use iso -mm-dd because the database indexes are predix based and are able to sort and build ranges. So you don't loose much. The problem is regarding the conceptually incompatible offset and #asDate. #asDate just

Re: [Pharo-users] why is concat of Symbols a string?

Hi, All symbols are interned in the Symbol table. If one does (#foo , #bar , #baz) and each returned value would be a symbol, then both #foobar and #foobarbaz would be registered in the symbol table. I would guess that's why the concatenated value is a string and not a symbol, to avoid

Re: [Pharo-users] Voyage and duplicated entry

Hi Hilaire, did you do VORepository current reset in the meantime? If yes, this could be the reason. If you do this, the smalltalk cache of the objects is reset and the next time the objects are loaded again from mongo and then they are no longer "the same" objects within smalltalk. I had a

Re: [Pharo-users] Voyage and Date

Hi Hilaire, it is interesting to see your posts and having similar topics as me when starting to use voyage. I ended up with saving ZTimestamps. But I will think about storing strings too, because this is more readable when having direct look into mongo. There was a discussion in slack a few days

[Pharo-users] why is concat of Symbols a string?

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

Concerning this problem, one option I found is to get far away of the Voyage/Mongo Date/DateAndTime representation/conversion and stick to string, not really efficience, but well... mongoBirthday ^ VOToOneDescription new attributeName: 'birthday'; accessor: (MAPluggableAccessor

It is really possible and we are working on a new implementation of talents based on anonymous classes. 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

Pablo I would not use talents. You can use an anonymous classes. Have a look at the chapter of https://ci.inria.fr/pharo-contribution/view/Books/job/BuildingLanguageKernels/4/artifact/build/book.pdf Thanks Denis, I will take a look . I think this is what i need. Tia Ing. Pablo
