Pay attention that my code was an experiement to build test first a mini powerpoint. So there is not much. > Is there a way to save and reload the slide show. Like in the good old > squeak days (TM) with a *.morph file? No but nothing prevent you to plug fuel for that? Now I was thinking that I want to rebuild it on bloc but I should not start before finishing a long list of todo. BTW I navigated so much in this old ugly code that "it is not the good old days." Sorry but I cannot let you say that. We are in the good new days! > > Would be a nice addition to recreate some of the presentation and > multimedia features known from Squeak now also in Pharo. To recreate. rebuild, redesign, of course! not to copy code! Pharo has never been against multimedia. Our goal is to have a solid base for inventing new things and to build a meta platform . I would have love to have Sophie running on Pharo. This is not by accident that we are working on - Athens - TxText - Bloc - Event touch - SDL and not just web app I remember that one person did a new desktop or something like that to build presentations.

Re: [Pharo-users] When to use a stream for concatenating text..

Using a stream avoids that. But there is a cost for handling the stream, too: [String streamContents: [:s | s nextPutAll: 'jlklkjkl'; nextPutAll: 'jlklkjkl' ]] bench. "'1,866,774 per second'" ['jlklkjkl' , 'jlklkjkl'] bench "'5,433,931 per secondâ" So it is only faster e.g. when adding to a string in a loop or on larger strings. But it reads quite nice, too, so I tend to use it without thinking about performance. Marcus

use String streamContents: [:s | s nextPutAll: 'jlklkjkl' ] or String streamContents: [:s | s << 'jlklkjkl' ] it is a great method for manipulating Le 10/3/15 19:09, sergio_101 a Ã©crit : > > it seems that in more cases than not, i find that developers use a > stream when concatenating some text strings. > > I am wondering if this is a smalltalk thing, or is there a real speed > benefit when using streams in this way. > > Thanks! >

Re: [Pharo-users] Settings Browser: Moose 5.1 exported settings raises error in Pharo 4.0

by stepharo

The problem is also when you rename a class. Having explicit class name is a problem. Damien C we wwna to extract and revisit the configuration approach of pillar to offer a nice way to support configurations. Now it is based on Ston and it will make the approach based on a little package. So for now ignore error is the best way.

configuration browser descriptions

by Sebastian Heidbrink

Hi! Here is another information based on my last beginners session. One should discuss if it might be useful and easy to implement to have a configuration browser that includes descriptions for the offered configurations. Beginners have no idea what Seaside, AltBrowser, Artefact,... stand for. Cheers! Sebastian

The -vm-display-null parameter is specific to Ian Piumarta's unix VM. It is part of the loadable VM module system that he made for sound and displays. You will find this in the various VMs that run on top of Ian platform code. The Windows VMs originate from Andreas Raab's code base, which has different VM command line parameters. For common things like starting a headless VM, it would be a good idea to make the command line parameters consistent across VMs. Maybe that could be done most easily in the start scripts, as opposed to the VM executables.

Re: [Pharo-users] Question about NeoJSON

by Esteban A. Maringolo

2015-03-12 18:09 GMT-03:00 Sven Van Caekenberghe <sven(a)stfx.eu>: > I don't really understand why you want to keep the original JSON. It is a bit like you don't trust the parsing and/or mapping. Now, the mapping I understand (somewhat). I guess this has to do with the fact that if you have a REST+JSON API he wants to preserve the JSON payload that was used to create the instance (in case of a POST). So you first parse the JSON, create the object from it, and then assign the JSON string to it (and this should never change). Some API's preserve the entire request (including HTTP headers) in the created/updated object. Esteban A. Maringolo

That would make sense if the jsonOriginalString is an immutable object (from the application standpoint) that you keep in order to preserve some sort of logging of how/where the object was created.
