Re: [Pharo-dev] A configuration framework

Hi Damien, I use a small extension to SystemSettings which handles checking that the target class exist before executing the setting. However you lose the runOnce ability.

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
