Mmh, I have been experiencing that too. Stdin and stdout aren't that well handled it seems. I write to the term using VTerm fwiw.

Re: [Pharo-users] Writing on stdout when redirecting the standard output

by Robert Shiplett

on linux I used to have a BASH shell "wrapping" script to address this redirect snaffu in a pinch with other interpreters ... Does that "ring a bell" with someone as a quick work-around ? My memory can be such a pain and I am on an old XP laptop just now ... I am quite sure I had to launch from BASH ... within Bash On 28 July 2014 11:46, FranÃ§ois Stephany <tulipe.moutarde(a)gmail.com> wrote: > > $ pharo Pharo-30852.image > /tmp/test.log > > Outputting somethind to stdout results in: > "FileWriteError: File stdout is closed" > > * Arch Linux > * Pharo 30852. > > $ pharo --version > > 3.9-7 #1 Thu May 15 18:29:30 CEST 2014 gcc 4.6.3 [Production ITHB VM] > NBCoInterpreter NativeBoost-CogPlugin-GuillermoPolito.19 uuid: > acc98e51-2fba-4841-a965-2975997bba66 May 15 2014 > NBCogit NativeBoost-CogPlugin-GuillermoPolito.19 uuid: > acc98e51-2fba-4841-a965-2975997bba66 May 15 2014 > https://github.com/pharo-project/pharo-vm.git Commit: > ed4a4f59208968a21d82fd2406f75c2c4de558b2 Date: 2014-05-15 18:23:04 +0200 > By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #14826 > Linux pharo-linux 3.2.0-31-generic-pae #50-Ubuntu SMP Fri Sep 7 16:39:45 > UTC 2012 i686 i686 i386 GNU/Linux > > > Did I miss something? > >

Multiple sorting helper

by Esteban A. Maringolo

Hi, I have a collection of objects and I want to sort its contents by more than one attribute (including nil values), and I thought somebody might have already done this. Something like: sorter := MultipleSortCriteria new add: #lastName; add: [:each | each personalInfo age ] ascending: false. aCollection asSortedCollection: sorter. Is there a package with utility classes for this? Thank you! Esteban A. Maringolo

But I would not overdo it, there is a real cost to this operation (scanning everything). In general I think it is better to amortise the cost over multiple operations. Sure. The reason to do is to remove the strong reference to the object. But it is just a test and I might not need it.

Hi Norbert, Neo-Caching was an experiment, a proof of concept, it has been integrated in Pharo. See category 'System-Caching', the hierarchy AbstractCache, LRUCache and TTLCache.
