Re: [Pharo-users] [DesktopManager] Ctlr - D (do-it) is blocked after installation of desktop manager

by Tim Mackinnon

Itâs always handy to put a <script> pragma in there anyway, so you can click on the triangle in the browser if you need to re-run it. Which reminds me - I was going to put it out there, that it might be handy to have something like a <reset> pragma, such that Pharo could have an easy menu to offer ways to reset frameworks it knows about. Itâs so frustrating trying to find out how to reset things like Iceberg, Glory, Seaside etc when things go wrong and you just want to go back to the start. I Amy propose this in a new thread to generate some conversation. Tim > On 8 Sep 2017, at 12:59, Ben Coman <btc(a)openInWorld.com> wrote: > > > > On Tue, Sep 5, 2017 at 5:41 PM, H.

Re: [Pharo-users] Pharo 6.0 Generating Ruby-on-Rails Applications

Re: [Pharo-users] Usability issues with Calypso

by kmo

If Tim had not posted this comment - "I love the fact you can move to a new method with unsaved changes and no nag prompt".- I would never have known that it was possible to do this. Since I always save my methods before moving on I had never experienced this behaviour. I think this is an another instance of Calypso violating "the law of least surprise". Just like the appearance/disappearance of the "new object" tab, this behaviour was totally unexpected by me. I think it is wonderful that you can move on to a new method before you save the one you are editing - but surely the natural way of achieving this is to make the tabs work more like tabs ina standard text editor. You should be able to have as many methods opened in tabs - saved or unsaved - as you want. Why not have a system where if you CTRL or SHIFT click on a method it adds that method to the set of tabs in the editing area? That's what I would have expected all along. When you see a set of tabs in a row you assume that you can add to them. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Teapot and Websockets

by Georges

I added two methods: Teapot>>WS: patternActionAssoc self addRouteMethod: (TeaMethodMatcher exactly: #GET) pattern: patternActionAssoc key action: (ZnWebSocketDelegate map: patternActionAssoc key to: patternActionAssoc value) ZnWebSocketDelegate>>teaEvalActionOnRequest: aTeaRequest ^self handleRequest: aTeaRequest When I do: Teapot on GET: '/ws-echo-client' -> ZnWebSocketEchoHandler clientHtml; WS: '/ws-echo' -> ZnWebSocketEchoHandler new; start. And go to localhost:1701/ws-echo-client in my webbrowser I get: WebSocket Test ws://localhost:1701/ws-echo CONNECTED SENT: WebSocket rocks RESPONSE: WebSocket rocks DISCONNECTED To avoid the WS: message: Teapot on GET: '/ws-echo-client' -> ZnWebSocketEchoHandler clientHtml; GET: '/ws-echo' -> (ZnWebSocketDelegate map: '/ws-echo' to: ZnWebSocketEchoHandler new); start For now I will use the WS: message, and hopefully in the future you come with a nice solution :) Georges -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi Manuel, Thanks very much for making this available and taking the trouble to get it working with the light theme as well.

When I first looked at the plugin with the dark theme (which I can't use, as I can't see it clearly) the colour change seemed to be less pronounced, but in the light theme, as Cyril says, it is too big a change. Thanks again, Alistair
