PharoJS
by Brad Selfridge Nov. 21, 2016

Does anyone know what the state of PharoJS is? I am looking at working on a big node.js project and would like to see if I could use PharoJS to do a lot of the work. ----- Brad Selfridge -- View this message in context: http://forum.world.st/PharoJS-tp4924045.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

FUEL not working
by HernÃ¡n Morales Durand Nov. 21, 2016

Nov. 21, 2016

Hi guys, Maybe I am doing something terribly stupid but FUEL is not correctly serializing a Set. I uploaded a video so you can check: https://youtu.be/wAQgbkqAXtk As you can see, there is 1 new object in the Set, on serialization the file grows, but on materialization the new object is not present. Any hint? Using Pharo 5 here. Cheers, HernÃ¡n

Nov. 21, 2016

So now I need to port my CPPBridge to Windows and I have to deal with this monster. And it would not be Windows if it did not make life a lot harder , so it defines its own types. Such types are handle_t / HANDLE TCHAR LPCTSTR PVOID also I will have to deal with Unicode , I have no clue how to proceed, any help is greatly appreciated.

Improving comments cool action
by stepharo Nov. 20, 2016

Nov. 20, 2016

Hi guys I would like to see how we could build a concerted action to improve the class and method comments in Pharo. Now we have package comments :) so we should take also advantage of them. I would love that a newbie is highlithed by class comments. So I would like to start to comment key core classes. I'm sure that if we all spend 30 min per week we can really have a huge impact. I was planning to start with collection classes. Now let me know if you want to help. Stef

Did you read https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… ? Did you check out the unit tests ? Some of them serve as examples.

Re: [Pharo-users] NeoJSON with Rest

This works for me: Say you have a class called MyObject and you want a JSON representation of it. On the *class *side of MyObject add this method: neoJsonMapping: mapper "For inheritance mapping to work, the schema/classname must be self, but the instance variables have to be enumerated manually per class" mapper for: self do: [ :mapping | mapping mapAllInstVars ]. On the* instance *side of MyObject add: asJson ^NeoJSONWriter toString: self. Now you can return JSON for any instance of MyObject with a simple: myobjectinstance asJson. This code gives you all the instance variables of MyObject as a JSON string, but you can change the mapping statement to tailor it to include exactly what you want. Hope this helps. -- View this message in context: http://forum.world.st/NeoJSON-with-Rest-tp4923754p4923762.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
