Re: [Pharo-users] Non-evaluating and / or

by Peter UhnÃ¡k

Hi, that's because you need to pass a block, since you want to postpone to execution. i.e. false and: [Transcript open]. (otherwise the binary operation Transcript open will take precedence over keyword false and:) You can always look at the implementation of those things â I always learn something from it. :) Â»and: alternativeBlockÂ« Peter On Fri, Apr 3, 2015 at 12:10 PM, Jan B. <bliznjan(a)fit.cvut.cz> wrote: > Hello > > I would like to ask how to do non-evaluating and. > As far as I know, & should be evaluating and and: should be non-evaluating. > However, I need to find a way how to use it properly. > > In "conventional" languages I would expect to work it like in following > example... > false and: Transcript open > Since false is... false... there is no reason to evaluate Transcript open. > But when I run this one in playground, transcript opens. > > Any help is appreciated. > > Jan > > > > -- > View this message in context: > http://forum.world.st/Non-evaluating-and-or-tp4817211.html > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. > >

Re: [Pharo-users] Non-evaluating and / or

by Blondeau Vincent

Hello, You should but a block after "and:". If you don't, the instruction will be always executed... The block represents a kind of conditional action. So if you want to do it works : false and: [ Transcript open ] Hoping that it will help, Best, Vincent BLONDEAU -----Message d'origine----- De : Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] De la part de Jan B.

Re: [Pharo-users] Voyage performance issue

by Esteban Lorenzano

could be. Write is not a fast action now with the mongo driver. Take into account that each object generates a graph of dictionaries who are committed to the DB. Depending on the complexity of that graph, you will have larger write times. you can try measuring time of two separated operations: [ serialized := VORepository current serializer serialize: theObject ] timeToRun. [ VORepository current resolver insert: theObject serialized: serialized withId: OID nextOID ] timeToRun. that might give you a better idea of what happens (you can also use the TimeProfiler to see where your time is consumed) if you have to write such collections in a regular basis, from there you can explore ways to speed up the process. Sorry not being able to help more, but the amount of information you give me is like going to the doctor and say âit hurts!â :P cheers, Esteban > On 03 Apr 2015, at 01:25, Josefina Arcidiacono <josefine2_94(a)hotmail.com> wrote: > > Hi! > I'm using Voyage with MongoDB. > I need to store an object with a large collection. > Since both are voyageRoot, there is a Mongo table with all the collection > objects and another with the first object pointing to them. > With 20,000 objects in the collection it's taking 30 min to save. > Â¿Is that normal? > > Josefina > > > > -- > View this message in context: http://forum.world.st/Voyage-performance-issue-tp4817087.html > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. >

Re: [Pharo-users] OrderedCollection remove:

If you think you need a loop, stop and find a better way, it likely already exists, in this case as someone else already mentioned either #removeAll: or #removeSuchThat:. Smalltalk isn't procedural, loops aren't your bread and butter. -- Ramon Leon
