Re: [Pharo-users] Pharo runtime engine

by Mariano Martinez Peck

Hi Charles. I don't have experience with VW, so I may be saying useless things. But in pharo, this is a good way of working from my point of view: - You develop your app with a Pharo image (Pharo image -> PharoDev image), the one that comes with a lot of packages and tools. - You create a Metacello configuration for your app which means that you can recreate and load all your application code and its dependences in a clean Pharo image. As you may know, Pharo includes several packages which are kind of third-part libraries, this means, are developed by other people than the "Pharo Developers". The last ones, take care about, what it is called, the PharoCore. So...PharoCore is developed and maitained by Pharo developers, and it is a small image, core. Then, we load several packages on top of it, and we build the Pharo image. This PharoCore can be considered as the PRE. At the moment of deploying an application, you can: - Adapt your metacello configuration (if necessary) so that now your app loads also in a PharoCore - Configure and customize the app. For example, you can change icons of the vm, and change stuff like that. Create a windows installer, etc. - Lock your image for production - Evaluate "ScriptLoader new cleanUpForProduction" which cleans a lot of garbage but also removes tests and things that you may not need in production. The idea with this is to have a smaller image. You can also read: http://code.google.com/p/pharo/wiki/HowToDeployAnApplication Cheers Mariano On Tue, Dec 28, 2010 at 12:04 AM, Charles Monteiro <charles(a)nycsmalltalk.org > wrote: > > first of all pardon my ignorance, trying to be a better community member > but > I'm still behind. > > Has the pharo team contemplated setting up the notion of an official "pharo > runtime engine" (PRE) , to be specific users would download the runtime > engine and subsequently only the "parcels" i.e. whatever the Pharo > counterpart is (.st file ins ?) is distributed to users. > > Although Cincom does not officially support this, its actually quite simple > to setup and its the way I am accustomed to delivering apps.

Multi window Pharo

by Charles Monteiro

Is it still the case the all UIs basically reside within the "one" host Window (World)? Is it not possible to have an app with multiple windows where one of the windows could for example be located onto a second monitor ? thanks in advance, -Charles -- View this message in context: http://forum.world.st/Multi-window-Pharo-tp3165573p3165573.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Pharo runtime engine

by Charles Monteiro

first of all pardon my ignorance, trying to be a better community member but I'm still behind. Has the pharo team contemplated setting up the notion of an official "pharo runtime engine" (PRE) , to be specific users would download the runtime engine and subsequently only the "parcels" i.e. whatever the Pharo counterpart is (.st file ins ?) is distributed to users. Although Cincom does not officially support this, its actually quite simple to setup and its the way I am accustomed to delivering apps. Many in the VW community do as well. I long ago abandoned the strip down model but rather "build up". However, the runtime image is indeed an image stripped down of development tools and etc. BTW, I also provide for a modicum of security by encrypting the parcels. thanks in advance, -Charles -- View this message in context: http://forum.world.st/Pharo-runtime-engine-tp3165570p3165570.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Loading Seaside into an existing image

by Mariano Martinez Peck

Hi Daniel. As stef said, I would go first for download a official Seaside one click image. At least, to get started. Once you are more familiar, you can see how easily you can install seaside 3.0 in your pharo image (the one you download from the pharo website). There are few differences in the provided tools of the Seaside one click image and the pharo image. So, if you are already familiar with a pharo image, then you way want to install seaside there, which should be something like: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigutationOfSeaside30'; load. (Smalltalk at: #ConfigurationOfSeaside30) load.

Re: [Pharo-users] Loading Seaside into an existing image

by StÃ©phane Ducasse

Hi daniel It depends on what you want to do. FOr my project I always like to start from a fresh image. Now do it incrementally - take a seaide official image and make sure your code load with a script using Metacello (firs gofer then Metacello) - once you are fit there, you just use the metacello invocation to load seaside. But do not go loading packages by hand. This is the way to get mad and frustrated :) Stef > First of all, do I really want to install Seaside into an existing image, or should I import my stuff into a dedicated Seaside image? > > After opening the Repository on 'Seaside', from the Monticello browser, which version of Seaside to I take from the left column of the Repository?

Loading Seaside into an existing image

by Daniel Klein

First of all, do I really want to install Seaside into an existing image, or should I import my stuff into a dedicated Seaside image? After opening the Repository on 'Seaside', from the Monticello browser, which version of Seaside to I take from the left column of the Repository? And then which one from the right column? I'm assuming I want the latest 'stable' version. I think it's 3.0, but I don't see it in there? I just took a look at the Seaside website and it looks like there is a 'one-click' install for Windows. Is this the best (recommended) way to get it? I don't mind doing things manually. Are there 'image' and 'changes' files that I can download without doing the 'one-click' thing? Sorry for the barrage of questions. Perhaps just a simple answer will suffice. Dan

Re: [Pharo-users] CPU utilisation

by Mariano Martinez Peck

In addition to Igor comment, there is also some effort in trying to make multiple core vms. For example, https://github.com/smarr/RoarVM/ Gemstone Smalltalk does use also different cores. And maybe Eliot is working on that for the CogVM (I don't know). Now I am wondering.....I remember (not sure) that in Linux you could specify which core to run certain process. If that is true, maybe you are able to run several vms at the same time in different cores? I am thinking in case of having to scale a web application for example.
