Re: [Pharo-project] Cannot be recompiled

by Martin Dias

Hi, (forwarded from pharo-users) Object subclass: #A instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. (Smalltalk at: #A) subclass: #B instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. Object variableSubclass: #A instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. I'm working in the "new class builder" [1]. It automatically propagates this format change to the subclasses, instead of raising the error like the current class builder does. ie, the class B becomes variable when A becomes variable. Do you agree?

Re: [Pharo-project] A Pharo launcher

by S Krish

Guess on a different runtime need: I had this VW Launcher for my own play in 2003 - 2004... on windows Similar needs, but different implementation: * Contained a base VW image with all mostly used base code loaded saved * The vwnt.exe * Through the inno setup configured this to be invoked when clicking *.pcl files in windows Usage: * Download a *.pcl file that is a complete application ( with config for prereq pcls if required ) * Open the vwnt.exe with the pcl as the input param to load first and run a predefined startUp method. Thereafter once I delivered the base package, found it easier to deliver upgrade bits.. either as cumulative or delta (.pcl for vw ) .. ******************************** This would be nice for Pharo too from an end user perspective of a delivered app. Deliver a few KB to few 100 KB fuel code package/ mcz file and it automatically links and opens with the pharo.exe in dev / runtime mode ( without dev tools) as configured.. But as I realized over few years for above... a) Like in Java, will have to deal with version issues...for the launcher package b) Identifying basic packages, optimizing startup time is a bit of challenge c) Duplicate , package version issues.. would come up eventually... But despite this all, I feel for the runtime deliverable experience, simplified I have this mcz, click and run experience would be nice to get school kids interested.. if not many others in IT cos too. >From a web Pharo Marketplace for instance if we have several apps ( just mcz files.. ) that are download, click and run on a pharo runtime.. without having any other overheads but few to 100's of KBs could be nicer..

Re: [Pharo-project] A Pharo launcher

by Esteban Lorenzano

yes... it is like the vmware pre-made virtual machines service. Of course you can create your own VMs (and probable most of the time you'll do it anyway), but you also can download pre-made versions (even uploaded for "other" people) :) Esteban On Apr 24, 2013, at 12:30 PM, Camillo Bruni <camillobruni(a)gmail.com> wrote: > > On 2013-04-24, at 09:01, Damien Cassou <damien.cassou(a)gmail.com> wrote: > >> On Wed, Apr 24, 2013 at 8:53 AM, Serge Stinckwich >> <serge.stinckwich(a)gmail.com> wrote: >>> Nice initiative !

In the end, for most pro users, and by that I rely on my experience with very complex 3D software, menus are mostly there to learn the shortcuts. That means they do not have to be super navigable (e.g. one big list) but logically structured (e.g. submenus). > When can we push that into 3.0 => push it as early as possible => improve it gradually

Most people here have scripts to download the latest image and install their presets, that clearly shows that a launcher with template images, much as templates in any other software, really is the way to go!
