Re: [Pharo-project] Smalllint for Traits

by StÃ©phane Ducasse

We agree. In fact the problem is that trait and classes are not polymorphic and this is what the implementation of andreas ws resolving. We will have to propose a solution to this problem one of these days. Stef > > btw2...

Re: [Pharo-project] [Update] Zinc-SSO OAuth 1.0 & OpenID Alpha Code & Live Demos

by CÃ©drick BÃ©ler

Hi, Any chance for a CAS implementation ? (http://www.jasig.org/cas/client-integration) I guess not because it's very different (and complex) compared to OAuth and OpenID, but I ask to have a confirmation :) Thanks anyway for the good work.

Thanks : Shift-Alt works by default. And thank you for the pointer to the Pharo 1.1 one-click install. -- View this message in context: http://forum.world.st/How-to-Meta-Click-on-Windows-tp4662780p4662790.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

I am using Moose 4.7 based off Pharo 1.4 on Windows 7 and use SHIFT-ALT to get halos. System > Keyboard > Control and Alt keys = Full Matching.

[Pharo-project] How to Meta-Click on Windows

by Euan M

I've just installed Pharo 1.4 and Pharo By Example (PBE) 1 on my Windows Vista laptop (with two button track-pad). I've attempted every modifier key (Shift-, Ctrl-, Fn-, Alt- and AltGr-) on both of the trackpad buttons, and I cannot bring up the Morphic halo (as an example use of meta-clicking) PBE suggests using the Preference Browser (System > Preferences > Preference Browser) to change the swapControlAndAltKeys option in the keyboard category. ( This is now System > Settings > Settings Browser, then System > Keyboard > Control and Alt Keys ) I've tried setting it to "Swapped" and to "Handled apart", but nothing brings up the Morphic halo. How do I meta-click in Windows? -- View this message in context: http://forum.world.st/How-to-Meta-Click-on-Windows-tp4662780.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

It works great but what I remember it was quite hard to convince HAProxy to do what you want to. This situation should (!) have change in the meantime. At least there should be some documentation for certain use cases. HAProxy is widely used in installations so that would be my hope. Apart from that I'm glad my current stuff can be handled by nginx only and I don't have to use any of HAProxy, varnish, etcâ¦ These are all good pieces of software with an awful way of configuring it. And you need to know exactly for what purpose they are designed. At the end they are not very flexible that's why you have to find the right software that fits your needs.
