Re: [Pharo-project] Class creation notification

by Mariano Martinez Peck

grrr shorcuts.. then I found AutomaticMethodCategorizerApplier which I don't care. And I don't care if I need to close and open again the TestRunner. So....what I mean is that class creation notification increases Fuel classes materialization like 50%. Do you think this is un-important enough to provide a way to NOT notify? I mean, should I provide a way to avoid that and avoid the 50% ? or it will be totally unsafe? Thanks!

[Pharo-project] Class creation notification

Hi guys. I was checking who needs to be notified when a class is created. If I follow correctly senders of #notify:ofSystemChangesOfItem:change:using: and friends, I don't really find too many listeners.

Re: [Pharo-project] Switching windows using CMD+right/left

by Pat Maddox

I've never figured out how to reliably switch windows in Pharo. There are a lot of things that I wish I could do with the keyboard but seem broken / unimplemented / buggy. So I just use the mouse most of the time.

[Pharo-project] response to an AJAX POST request

by Bernat Romagosa

Hi lists, I'm trying to get Amber and Pharo to talk to each other by using Ajax. So far, using an Ajax wrapper that Laurent wrote, I managed to get Pharo to receive a message from Amber by doing: |ajax| ajax := (Ajax url: 'http://localhost:4001/amber/'). ajax options at: 'type' put: 'POST'; at: 'data' put: 'Hi Pharo!'; at: 'timeout' put: 500. ajax onSuccessDo: [console log: 'ok!']; onErrorDo: [console log: 'not so ok...']. ajax send This is captured by a Swazoo resource, that does the following: answerTo: aRequest | response | [aRequest postData stream anyDataReady] whileTrue: [Transcript show: aRequest postData stream next]. response := HTTPResponse ok. response contentType: 'text/plain'; entity: 'Done!'. ^response My intention here is just to read the message data and return an OK response, but for some reason stream anyDataReady keeps evaluating to true even when there's no more data to read, so the code underneath is never executed. The Transcript shows 'Hi Pharo!' though, so I'm sure the request is being received and read. Any light shed on this would be of great help... Thanks! -- Bernat Romagosa.

[Pharo-project] Two objects with same hash

If you are on Windows you can use Microsofts GUID. I wrapped them in http://www.squeaksource.com/COM.html as class COMGUID. They are unique in time and location so you need no additional date. If I remember correctly the UUID plugin for Windows used them directly as the underlying generation algorithm ... I also expected UUIDs (for instance if generated on Mac or Linux) as unique in time and location so it should not be possible to generate the same value at the same time on two different computers.

The fallback code uses current time as part of a PRNG seed, but also attempts to achieve a type 4 UUID. Cheers, Henry
