Re: [Pharo-dev] ZeroConf scripts download progress

by Esteban Lorenzano

does not work. bash will execute the script (without any option). What I ask is: how do you tell bash that he needs to transfer a flag â-vâ to the downloaded script?

I can imagine having something similar to what you have done to have that is more focused on a specific domain like data analysis or ecological modelling for me. > The result was that people actually got excited, and the message rippled a > bit and I got to do several other demos outside the public session.

Maybe, you can use also the extended TutorialBrowser from Stephan Eggermont.

Compressing changes

by Esteban A. Maringolo

After installing a Metacelllo config referencing some other projects (Seaside, Glorp, Neo*, etc.) the base Changes file went from a few Kb to ~40Mb. Can this changes file be "condensed" somehow? Regards, Esteban A. Maringolo

Re: [Pharo-dev] [website] new news entry: talk NDC Oslo

Thanks :). Just some background information: As you can see, I used the GTInspector to show the liveliness of the system. I actually used the Moose image + some other goodies (like Seaside, Postgres connection and a couple of others). I tried this story for the first time, and while it still needs a bit of polishing, I think it works well on two levels: - you can use it as an argument for people to start adopting Pharo as a programming platform by emphasizing the liveliness, - but at the same time you can use the same demo to show how using Pharo can replace scripting, querying and charting tools for common tasks like string, file system or db manipulation. This in itself is a niche that we can tap on. The result was that people actually got excited, and the message rippled a bit and I got to do several other demos outside the public session. Every step you saw in the demo is setup through a script that gets triggered from the world menu. These scripts spawns windows and sets the state of objects. It's really simple, but it accelerates the demo. My goal is to get a demo that can be repeated by others in other contexts out of the box. There are still some setup issues, but once I get it done, I will make it more public. In the meantime, if you want to contribute or play with it you can use the following script in a Moose image: Gofer new smalltalkhubUser: 'PharoExtras' project: 'PostgresV2'; configuration; load. (#ConfigurationOfPostgresV2 asClass project version: '2.0-baseline') load. Gofer new smalltalkhubUser: 'Moose' project: 'GToolkit'; package: 'GT-InspectorExtensions-PostgresV2'; package: 'GT-InspectorExtensions-XML'; load.

Re: [Pharo-dev] Brainstorming Pharo4

Hi everyone. I would also add here the issue with side-scroll handling. I donât know if anybody uses this âfeatureâ but itâs really annoying that when you use trackpad it always switches focus to adjacent panels.
