Re: [Pharo-users] What is "Primitives"?

by phil＠highoctane.be

There is no VMMaker UI tool anymore for the PharoVM. For continuous integration, it sucks anyway. So, you have the VMBuilders and CMake related classes. I like that better. There are options in each build method for specifying which plugins are to be used. e.g. do not use the ObjectiveC bridge in Windows...

Re: [Pharo-users] What is "Primitives"?

by Nicolai Hess

Thank you. It is not about how to build a vm. I do have some experience on this (mostly squeak vm). But I find it rather difficult to follow the current active way on doing so. In Mariano blogs he is using vmmaker tool as well. It just didn't work for pharo anymore. For example, you can load vmmaker packages. (really difficult on with a normal image (you need all kind of dependent packages), or you can use the generator.image from pharo.src. But VMMakerTool openInWorld fails. I don't know - why, - if it is supposed to do so, - or how other people working with vm source. regards nicolai 2013/11/29 Ignacio MatÃas Sniechowski <0800nacho(a)gmail.com> > Hi Nicolai, > A very good source is Mariano Martinez Peck's excellent blog.

Re: [Pharo-users] What is "Primitives"?

by phil＠highoctane.be

Hi Nicolai, Question1 The Primitives you mention is a class variable. Put your cursor on it and hit the blue "C" button on the right of the Nautilus code pane to see where it is used. You'll notice that it is initialized in DiskStore class>>useFilePlugin useFilePlugin Primitives := FilePluginPrims new FilePluginPrims in turn provides an interface to the real file plugin. e.g. FilePluginPrims >> size: id "Answer the size of this file." <primitive: 'primitiveFileSize' module: 'FilePlugin'> self primitiveFailed So, class variables are WrittenLikeThis and you may thing that it is a class. But it is either a class variable or a global (e.g. Display, Transcript) In a workspace, try: Display class <printIt> Transcript class <printIt> You'll see the real classes. When using spotlight for example, you'll never find anything if you type Display for example. Even if the completion will propose something to you (hey, someone fixing this?) Question2 If you want to load VMMaker, you have to do it from the GitHub directions. There is a step where you do: cd image && ./newImage.sh and it loads all you need and you end up with the generator image. I've been using it in my fork https://github.com/philippeback/pharo-vm and the canonical repo is https://github.com/pharo-project/pharo-vm Follow the directions of the README.md and you'll be ready with ease. If you use OSX, it is working very smoothly. Windows will require some more fiddling but there is nothing stopping you. The generator already has VMMaker in. Now, please bear in mind that the PharoVM isn't the same VM as Squeak uses, so, the process is not with the Morphic based VMMaker tool (green thing) where you select plugins etc. Here, you are going to use the PharoVMBuilder which does all of the automation. ./pharo generator.image eval 'PharoVMBuilder buildWin32' will generate all CMake files, all Slang based files etc. I plan to do a video of all the steps very soon. This will help. Now, the VMSimulator isn't fully operational in the PharoVM, I am working on getting it right. At this point, it executes bytecodes without problems, but we need to port some more code to the new transcript, filesystem etc. Just a question of doing it. I am looking at that, hopefully this will work in december. Hope this clarifies the situation for you.

Re: [Pharo-users] What is "Primitives"?

by ClÃ©ment Bera

Well use the generator image you can find on the pharo repo, it is hard to build such an image by hand. This code: Primitives lookupDirectory: encodedPath filename: encodedBasename Should be: FilePluginPrims lookupDirectory: encodedPath filename: encodedBasename Now I don't why this was not correct (File management is pure magic to me). I would recommend you to post question about VMMaker not in this mailing list, because few people can answer here, but instead in the pharo-dev mailing list OR Squeak-vm-dev.

What is "Primitives"?

by Nicolai Hess

Looking at the code for DiskStore>>basicEntryAt: I find this code: "Primitives lookupDirectory: encodedPath filename: encodedBasename)" What is this "Primitives" not a class? I am suprised there is some code that I can not find the source for. Ok, it has something to do with vm primitives, and I know that code like <primitive: 'primitiveDirectoryEntry' module: 'FilePlugin'> is in the vmmaker-package for FilePlugin. BTW it is terrible hard to load vmmaker in a "normal" image. Now I use the generator.image from pharo http://files.pharo.org/vm/src/. But even in this image it is not possible to load the vmmaker tool.

Finalization

by Sean P. DeNigris

I found the following list threads... http://forum.world.st/Finalization-question-td1300962.html mentions #beFinalizable, which doesn't seem to exist. I guess it was just an example, but seems like it should be added, no? In http://forum.world.st/object-finalization-td3771196.html Igor suggested that the key is to do: WeakRegistry default add: obj. This guarantees? that #finalize will be called when the object is garbage collected. I'm asking regarding my recent work wrapping the FMOD sound library with NativeBoost. I'm thinking my NBExternalObjects should release their resources when no longer referenced. I want to say: FmodSound>>#finalize self primReleaseSound: handle. So I've pieced together that I would have to also write: FmodSound>>new instance := super new whatever; beFinalizable; yourself. Object>>#beFinalizable WeakRegistry default add: self. Am I correct that: 1. The above code would cause the resource to be safely released when the sound object was garbage collected? 2. This approach would be a good way to manage these types of resources? Any hints would be appreciated as to the best way to accomplish managing these...

Snap4Arduino pre-alpha release

by Bernat Romagosa

Hi list! I know people don't usually make announcements of this kind here, but I've gotten much help from this list on SerialPlugin and NativeBoost questions, so I wanted to let you know I've managed to release the pre-alpha version of Snap4Arduino. Snap! is a Scratch reimplementation written in Javascript by Jens MÃ¶nig and Brian Harvey, with advanced programming concepts such as first order functions, closures or continuations. As Brian Harvey puts it: *In the glory days of the MIT Logo Lab, we used to say, âLogo is Lisp > disguised as BASIC.â Now, with its first class procedures, lexical scope, > and first class continuations, Snap! is Scheme disguised as Scratch.* Snap4Arduino is a modification of Snap! plus a server written in Pharo that allow you to live-program Arduino boards very easily. http://s4a.cat/snap I've used Zinc as a web and websockets server, and the Arduino package to achieve communication with the board. I've decided to not wait for the MacOS CogVM serial port bugfix because I really wanted to release something before the end of November, but everything else is in place, so once the VM is fixed, it'll be just plug and release! :) Thanks a lot for your help! -- Bernat Romagosa.

In Gjallar we used the ini format and it often works just fine for "settings". :) But just to throw in something from the sideline, Tirade is also quite nifty: "Section 1" param1: 'value1'. param2: 123. "Section 2" blabla: $a. ...as you can see it is "just Smalltalk messages". One disadvantage of Tirade would be that you need to remember the "." at the end of each message. An advantage is that you don't need to "parse it", you just implement the messages in some class and then you can use the the reader in Tirade to just "feed" those messages to that object.

Would you use > STON to write a configuration file? Yes, definitively. If you write it out with the pretty print option, it is quite readable/editable. You can also both read and write. If non-smalltalkers are involved, JSON is a simpler alternative that requires more work from your side.
