Re: [Pharo-dev] Color arithmetical operations are broken

> > I would not change the alpha at all. Instead, set alpha 255 in > setPrivateRed: r green: g blue: b It makes sense to be consistent. However blindly setting it to 255 is sometimes unexpected too: Color transparent + Color transparent is assume to get Color transparent and not black. Maybe for + we could add alphas, but for subtraction take the smallest alpha of two colors?

Any experienced Pharoer is going to use ZeroConf or PharoLauncher anyway. The website is for new users, so we should provide something as usable out of the box as possible. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Pharo-4-0-Download-options-tp4813741p4813761.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Ah, I see. Is there any way we can link to the latest build from the CI server, though? http://files.pharo.org/platform/Pharo4.0-win.zip ? That seems to be built automatically by Jenkins. So why not just link to that? On Fri, Mar 20, 2015 at 8:07 PM, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > My other question still stands, then.

For Pharo 3 there are buttons in the download page for each platform that contain everything (image, vm, source), so I would expect once Pharo 4 is relased the button will download Pharo 4. Peter

I think I didn't scroll down far enough, and didn't see that option. Thank you :) My other question still stands, then. Is there any reason why we don't include the full release in the Download Pharo 4 link off the main Downloads page?

Pharo 4.0 Download options

by Dmitri Zagidulin

Hi all, I've been working on a project in Pharo 3.0 ( an update to the pharo Riak database driver, over at https://github.com/SmalltalkZen/phriak ), and I figured I'd try to see if it works in Pharo 4. I went to the Download Pharo page at http://pharo.org/download and saw the 'Development version: Pharo4' section. So far so good. I tried the 'Download latest Pharo image' at http://files.pharo.org/image/40/latest.zip first. But that only yielded an image and .changes, but no sources (or VM). So, not so good for development, right? Tried Zeroconf next, at http://get.pharo.org/alpha But that too had only .image and .changes, with no source or VM. (Or, at least, that's the only thing it listed under Artifacts. Does it also download source and VM once you run the script?) I eventually dug around in the CI server (https://ci.inria.fr/pharo/ ), and saw the small Full Download (Image+VM) link for my OS. Success! Couple of questions: - Am I missing something that's obvious to seasoned Pharo devs? How do you guys download new versions of Pharo, with sources and everything? - Is there any way we can include a full download option (image, changes, sources & VM) on the Download Pharo page? (So that new users don't have to search around on the CI server)? - Does the VM change, when you go from Pharo 3 to 4? Or can you just use a 4.0 image with the VM that came in the 3.0 zip? Dmitri
