Re: [Pharo-users] command line command from pharo image

by Sabine KnÃ¶fel

Hi Torsten, Sean, http://smalltalkhub.com/#!/~OS/OS-Windows looks great. I have not found a solution yet to send a call to OS from pharo (I develop with mac since a few weeks now and deployment is currently windows) and I am thinking about moving to Pharo 3.0 for further development due to the OS call problem. Do you think, Pharo 3.0 is ready to use it for development or should I wait and look for another solution?

This is exciting that you've already wrapped that stuff! I had no idea, there's probably so many great things out there. We could really use a PharoMap... I will take a look at your project. Maybe something could be integrated with NB core.

Re: [Pharo-users] [Pharo-dev] Json case: Mapping objects to dictionaries

by Esteban A. Maringolo

Norbert, I'm currently building the dictionaries myself. I have a specific domain class of mapper for each "message" (JSON). The mapper builder manually builds my domain objects from the dictionary returned by "JSJsonParser parse: aString", when writing creates a Dictionary and sends #asJson to it. E.g. I have a EventBuilder which can build an Event from a JSON string or viceversa. I used NeoJSON in the beggining and it's blazing fast (because it is stream based), but I couldn't get my head around some particular cases (which I don't remember now, sorry). I WILL give another try, but with time to fully understand it. In the Java side of my app, this is one of the simplest things to deal with, manually to read and write, by using JSONObject and JSONArray, there's not more of it than this. Regards, Esteban A.

If we talk about JSON there are three things: Objects, JSON structure (being dictionaries and other collections in pharo) and JSON strings. Writing to another server or to a file producing JSON strings seems to be enough. But using it for another system like MongoDB or ElasticSearch this does not work. Here the common interface seems to be dictionaries. With ElasticSearch mapping dictionaries to JSON and MongoDB mapping dictionaries to BSON.

Json case: Mapping objects to dictionaries

by Norbert Hartl

What would be the best software to map my objects to dictionaries? There are a lot of packages in pharo that deal with JSON somehow. But it seems none does mapping from objects to dictionaries and is standalone. Weâve got - NeoJSON package . Maps objects to strings directly for performance reason - JSON package. Maps string to JsonObject (subclassed from dictionary) - Voyage magritte based mapper: Closest to what I find useful but buried inside of Voyage. And Iâm not sure it would be easy to factor out this module as a standalone mapper. - Seaside javascriptâ¦ : I forgot what it really does. I often shy away looking at it because I donât want to suck in all the dependencies. Iâm asking because for me this is an important asset. If we talk about JSON there are three things: Objects, JSON structure (being dictionaries and other collections in pharo) and JSON strings. Writing to another server or to a file producing JSON strings seems to be enough. But using it for another system like MongoDB or ElasticSearch this does not work. Here the common interface seems to be dictionaries. With ElasticSearch mapping dictionaries to JSON and MongoDB mapping dictionaries to BSON. So a good descriptive way to map objects to dictionaries would be a good thing to have. Any thoughts? Norbert

OSProcess command: 'something' does not work on windows

by Sabine KnÃ¶fel

(continuation of http://forum.world.st/command-line-command-from-pharo-image-td4727022.html) OSProcess command: 'something' works fine on mac but does not work on windows. If I debug in it I arrive at a primitive call in WindowsOSProcessAccessor>>primCommand: The comment is saying something like "This primitive has been replaced by #primCommand:stdIn:stdOut:stdErr:, and will be removed in future versions of OSProcess." Question: How to call a command line command from windows (AND mac)? Do I have to write two different codes for the 2 os systems? I dont want this :-) I am on Pharo 2.0 Sabine -- View this message in context: http://forum.world.st/OSProcess-command-something-does-not-work-on-windows-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] About deprecation and unit testing

by jtuchel＠objektfabrik.de

Hi guys, Deprecation is a subclass of Warning, not Error. And I think this is absolutely correct. So the basic question here is if the action on Warnings and Notifications in general in SUnit is correct or should be changed. This is not necessarily limited to Deprecation. Of course we need a possibility to test assertions about Deprecations and other Notifications as well, so it sure is not a good idea to make "transparent" changes and simply ignore Deprecation or any other kind of Notification/Warning.

command line command from pharo image

HTH Hi Sabine, Sean, PLEASE NO WinExec, this is long deprecated and only for 16bit compatibility see http://msdn.microsoft.com/en-us/library/windows/desktop/ms687393(v=vs.85).a… As you see on MSDN CreateProcess() API should be used. If you are on Pharo 3.0 look at my "OS-Windows" project loadable from the config browser. You will find the class WinProcess with methods like #createProcess: (nonblocking) and #createAndWaitForProcess: (blocking) there. It already uses CreateProcess API. With the package you can for instance run the command processor: WinProcess createAndWaitForProcess: 'cmd.exe' You also have access to the environment like WinEnvironment getEnvironmentVariable: 'PATH'. See the documentation at http://smalltalkhub.com/#!/~OS/OS-Windows for more examples. Bye T.
