We use http://smalltalkhub.com/#!/~TaMere/DeployUtils It loads a JSON files in the "config/" directory sitting next to the image. It handles multi-environment with the "PHARO_ENV" env var. We use this to have a different configuration in development/staging/production Check the DUEnvironment class for usage.

Re: [Pharo-dev] Experience makers

by Martin Dias

Hi, @Stef: Previewing an scenario like yours, where not always you want to install my experimental tool, my script [1] displays a button morph for 3 seconds which the user can press to cancel the installation. Not that fancy as a manager tool, but I think it works. But I recognize it can be annoying to force users to use external tools to setup scripts in the preferences directory...

Re: [Pharo-dev] A configuration framework

by Esteban A. Maringolo

I use JSON for that purpose. Then it's a tree of nested dictionaries. No more than two levels though. You could also use STON. I know you asked for a framework, but unless you need something very specific, JSON is, IMO, the simplest thing that could possibly work. Esteban A.

fixing 'format on display' and 'format on accept'

by Paul DeBruicker

Hi - I'm going to get 'format on display' and 'format on accept' working in Nautilus. In Pharo 3 in the settings browser under 'code browsing' there is a 'pretty print' check box. As far as I can tell it doesn't affect code displaying at all in Nautilus. Is it OK to repurpose that checkbox as a control for 'format on display' and to also add a check box right there for 'format on accept' ? If not what would be better? Thanks Paul

A configuration framework

by Damien Cassou

Hi, I need a framework that will help me make my application configurable. This framework must save and load the application's configuration to/from a file. I'm not happy with the System-Settings framework (that I'm currently using for the Pharo Launcher) that saves executable code because, when the application evolves, the old code in the configuration file might not work with the new application. Is there something around already? -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." Winston Churchill

Yes, it is a well-known library written in C++. Concerning your problems: i never used it, and i cannot even guess why it behaves differently on different platforms, perhaps you should contact library authors first? Do you create socket via zeromq library, do sockets managed through it? To make sockets to not block the VM, just using a nice library is not enough: you must wire the socket events with VM process scheduling logic through signaling the semaphores etc.. Else you must always use non-blocking calls in C library. > Thank you for the indication about performance, I will take it into account > My first step is just to make experiments that works > to be comfortable with both nativeboost and zeromq. > This experiment is done with two different pharo vm processes > (the client and the server) started manually, and the same > in C. > This library has nice patterns that makes it very interesting from a > parallel computing perspective > (request/response, publisher/subscriber, push/pull , etc). > The guide is here and is worth looking at http://zguide.zeromq.org/page: > all > I know you will be interested in, it has similarities with your > old hydra project > :) > > Well, parallel computing is broad area.. with zillions goals and solutions. The setup you described is not what i wanted to achieve with Hydra. Running multiple instances of same VM ~= running single instance of VM which can manage multiple native threads. But sure thing you can achieve similar results using both approaches. The difference is in how fine grained your control over consumed resources, namely memory and CPU. -- Best regards, Igor Stasenko.
