Re: [Pharo-dev] About configuration of image projects

That's really cool. I guess it could be merged with the kernel bootstrap of Guille in order to create a full Pharo image from source. :) 2013/10/1 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> > Hi guys > > I started to work on creating configuration for all the projects inside > the image > > RB > Spec > Zinc > Ring > OPAL > AST > Nautilus > > KeyMapping > > why because I want to be able to express the dependencies so that we get a > modular system and that > we can build it based on miniImage. > > So if you got some configuration in the past and your project got > integrated in the image please let me know. > > - Pharo/ASMJit > - Pharo/Fuel > - Pharo/NativeBoost > - Pharo/Athens > Got them > > Stef >

'Refactoring-Environment' with: [ spec requires: 'AST-Core' ];

by StÃ©phane Ducasse

Hile going over the old refactoring browse configuration I noticed 'Refactoring-Environment' with: [ spec requires: 'AST-Core' ]; and I really wonder if this is true. Stef

About configuration of image projects

by StÃ©phane Ducasse

Hi guys I started to work on creating configuration for all the projects inside the image RB Spec Zinc Ring OPAL AST Nautilus KeyMapping why because I want to be able to express the dependencies so that we get a modular system and that we can build it based on miniImage. So if you got some configuration in the past and your project got integrated in the image please let me know. - Pharo/ASMJit - Pharo/Fuel - Pharo/NativeBoost - Pharo/Athens Got them Stef

The zip files seem to set "Content-Length" when downloaded. The whole idea of chunked transfer encoding is to make it easier for the server: it does not have to buffer and compute a total size upfront. BTW, there are other cases in HTTP where Content-Length is not set as well. It is just how it is. And yes that means silly progress indications.

HTTPProgress Content-Length v.

Pharo Project Catalog List

by Alexis Parseghian

> this is great it shows up in the catalog list. > https://ci.inria.fr/pharo-contribution/job/PharoProjectCatalog/HTML_Report/ Having such a centralized list of Pharo(-related) project is a reat resource. Hadn't realized previously that it was available. A lot of those projects have a non-obvious name, it might be interesting to have a few descriptive words directly in the list above (when available), rather than just the project name ? Minor bug : when you look up any particular project in a separate browser window/tab, the page title is always Â« truc Â» :)
