Re: [Pharo-users] PharoJS

by Noury Bouraqadi

Hi Torsten, Thanks for the feedback. I have been pushed to make it public right before ESUG. I'm trying my best to make it clean and documented. If you are using a Mac, the examples I provide on http://car.mines-douai.fr/pharojs/ <http://car.mines-douai.fr/pharojs/> should work out of the box. For other platforms (Windows & Linux) I need the command line to open a web browser on a specific URL. Any hint? Regarding the naming PharoJS is more than a bridge. It allows: -Develop and test apps in Pharo -Generate a javascript file for a standalone app Noury > On 15 Jul 2015, at 11:28, Torsten Bergmann <astares(a)gmx.de> wrote: > > ClÃ©ment Bera wrote: > >> What is PharoJS ?

PharoJS Documentation

by Noury Bouraqadi

Hi, I started a documentation on how to use PharoJS at http://car.mines-douai.fr/pharojs/. So, far it covers: - download/ install, - evaluate expressions in the PharoJS workspace and see them perform on a web browser - running tests in Pharo (e.g. using the plain TestRunner) that perform some code on a web browser. The assertions are performed in the Smalltalk world :-) - exporting javascript file from Smalltalk classes to make a standalone app. Noury -- http://twitter.com/#!/NouryBouraqadi http://car.mines-douai.fr/noury

Yes there is SqueakJS from Bert https://bertfreudenberg.github.io/SqueakJS/ and I would have expected "PharoJS" to be the same for Pharo. At least I would "reserve" the name for the case Pharo images work on it as well. Unfortunately Noury Bouraqadi now took this "PharoJS" name for his Pharo -> JavaScript compiler http://car.mines-douai.fr/2015/07/develop-in-pharo-run-on-javascript/ leading a little bit to this confusion. I would have called the project "Pharo JavaScriptBridge" like the config and the repo http://smalltalkhub.com/#!/~noury/JavaScriptBridge I loaded the config from the SmalltalkHub repo and then: ConfigurationOfJavaScriptBridge loadBleedingEdge tried JbClientControllerBridge startOn:80 but were hit by several errors. In my opinion a minimal HOWTO would be required. Thanks Torsten

Re: [Pharo-users] NativeBoost and variadic functions

Hello Igor, Thanks for your answer. I implemented something like that for the printf function: Basically, it generates a method with matching arguments and executes it. *printf:* stringFormat *args:* tab > > | argNumber functionArgs functionPrototype methodCorpse methodSelector > argsArray | > > ((tab size % 2) = 0) ifFalse: [ > Transcript show: 'error'. > ^self. > ]. > > argNumber := 0. > functionPrototype := 'printf: stringFormat'. > functionArgs := ''. > methodCorpse := ''. > argsArray := (Array new: (tab size / 2) + 1). > argsArray at: 1 put: stringFormat. > > 1 to: tab size by: 2 do: [ :i | > functionPrototype := functionPrototype, ' arg', argNumber > asString, ': ', (tab at: i) asString, argNumber asString. > functionArgs := functionArgs, ' ', (tab at: i) asString, ' ', (tab > at: i) asString, argNumber asString, ','. > argsArray at: argNumber + 2 put: (tab at: i + 1). > argNumber := argNumber + 1. > ]. > functionArgs := functionArgs allButLast. > > methodCorpse := functionPrototype, Character cr asString, ' > <primitive: #primitiveNativeCall module: #NativeBoostPlugin>', Character cr > asString, Character cr asString, ' ^self nbCall: #( void printf ( String > stringFormat,', functionArgs asString, ' ) )', Character cr asString, ' > module: NativeBoost CLibrary'. > > methodSelector := self class compile: methodCorpse. > > self perform: methodSelector withArguments: argsArray. > Then you can call it like that : MyClass printf: 'Test of printf.

I also tried it for some other variadic functions and, on my computer (I am running archlinux), it seemed to work for every type of argument except "float". It works fine for "double" though. For "char" you need to pass the integer ASCII value directly for it to work. I tried with "Character value: xxx" but it didn't work. I know that this is very hackish and very bad, and I am aware it has some drawbacks. Moreover I am not even sure it will work everytime. But for now it seems to work ... 2015-07-13 19:24 GMT+02:00 Igor Stasenko <siguctua(a)gmail.com>: > > > On 10 July 2015 at 10:18, Matthieu Lacaton <matthieu.lacaton(a)gmail.com> > wrote: > >> Hello, >> >> Is it possible with NativeBoost to create a binding for a variadic >> function ? >> >> I've seen the printf example in NBCPrinter but this implementation is >> kind of cheating since it always pass just a %s as format and one already >> formatted string to the C function. >> >> I've written a simple variadic function which adds every integer it >> receives as argument (first argument is for the number of following >> arguments) : >> >> int add(int number,...); >> >> In Pharo I've tried something like this : >> >> *add: *number *arg1: *first *arg2: *second >>> <primitive: #primitiveNativeCall module: #NativeBoostPlugin> >>> >>> ^ self nbCall: #( int add (int number, int first, int second)) >>> module: 'libMyLib.so' >>> >> >> and it works fine with two arguments. >> >> Basically, doing so, I would need one method per number of arguments so >> it's not very cool. >> >> I thought that maybe I could pass an array as argument to my Pharo method >> but I didn't really find a way to figure out how to define the nbCall >> without having a "Generic failure". >> >> *add: *number *args: *anArray >>> <primitive: #primitiveNativeCall module: #NativeBoostPlugin> >>> >>> ^ self nbCall: #( int add (int number, ??? anArray)) >>> module: 'libMyLib.so' >>> >> >> Do you have an idea ? >> >> > In short, there's no marshaller for converting an array of items, to same > number of things on stack.

I fixed the file, now we should wait for the continous integration server.

I don't know if is possible to see details on each version by going to the underlaying system.

Re: [Pharo-users] PharoJS

by Andy Burnett

Hi guys, It is a project from Noury - at the Mines school. Just do a google for Noury and PharoJs I found out about it from Torsten's blog - always worth reading :-) AIUI, what it does is convert Pharo code - in the fly - to JavaScript. I can't say much more because I haven't got it to run. However, it is on small talk hub, so ease give it a go.

Thanks Jannik for your quick answer! we're working on the workshop right now, so getting this support is really encouraging for we all and sorry if I don't go th the specific mailing list in this hurry, but I will be using Phratch in the future, so wait for us there.

Hi Offray, you can use the phratch mailing-list to ask specific questions: phratch(a)googlegroups.com. About your problem of MNU. Could you provide more information. I cannot reproduce your problem: - I downloaded phratch 4.0 from here: http://www.phratch.com/phratch/phratchinstall - run it - click on the category "operators". It works for me. For your second question: There is a block "clean pen trails" that erase all the drawn lines. I will be happy to answer other questions :) Best regards, Jannik 2015-07-14 22:12 GMT+02:00 Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> : > Hi all, > > Today we started to use phratch to a group of people without much of any > experience with computer programming.

(Kind of urgent) Phratch: operators don't work at all on last verion!

by Offray Vladimir Luna CÃ¡rdenas

Hi all, Today we started to use phratch to a group of people without much of any experience with computer programming. The idea is to have a workshop today and tomorrow start with more symbolic and abstract approach using Pharo and give them a taste of the several levels of programmig and exploration this environment provides. But my main problem is that operators dont work on Phratch. We get a MNU as soon as we select the operators button which is a real stoper for any advance stuff. We're using the currently available package from the download page. Can somebody help me on this? Also: Â¿How can we erase a line drawn with the pencil on the background? I will be sharing more questions as they come. Thanks, Offray

Re: [Pharo-users] PharoJS

by ClÃ©ment Bera

What is PharoJS ? Are you talking about Pharo on top of the Bert's SqueakJS VM ? If so, it starts, but some primitives fail making it freeze after a short while as you describe. It would be fun to have it running even though most of the Pharo folks went into the Amber direction for Pharo on Javascript. 2015-07-14 19:46 GMT+02:00 Esteban A.

Copy-Paste form external sources does not work on Windows 8.1

by Dominique B.

Hi dear all, I am currently taking a couple of tutorials on Pharo and I noticed that cutting and pasting code snippets from the web, pdf, notepad, ... to Pharo 4.0 was not working on my Windows 8.1 installation. I double checked that versions 3.0 and current 5.0 exhibited the same behavior on 8.1.I double-checked this problem does not manifest on Windows 7. Am I the only one to experience it?Thanks in advance,Â Dominique

Hello, I have the same problem and it seems to be random. It is related to font cache. I opened a bug related to it: https://pharo.fogbugz.com/f/cases/15944/Image-crash-on-Pharo-due-to-fonts-o… I will raise the priority because it is very painful...

I use latest image 50170, latest (9th July 2015) Windows VM, Windows 7 64bit. So there is my vague description: When I load some project, modify it few times and save it, then SOMETIMES (seems random to me) when I try to open this saved image, it immediately crashes VM and does not even produce crash.dmp file (well, it creates it, but empty). For example, I have such image... I save it, do not close it, try to open it, crash, save it again, try to open it, it runs, save it again, close, try to open it, crash. Without any change inside the image by my hand. I tried doing something similar with clean image, but it never corrupted it. I am unable to open such image even on my Linux machine. It at least generates output when segmentation fault happens: http://pastebin.com/KLry40Hu HDD I am saving it to does not show any signs of damage, everything else is working (and saving) just fine. Here is such crashing image: http://www.mediafire.com/download/h5vhh7c40cl1w15/Pharo+5.0+%28beta%29-5017… and here is the same image saved again which runs fine: http://www.mediafire.com/download/86djppsn1ds3c0o/Pharo+5.0+%28beta%29-5017… However, when I open this "ok" image in linux, it causes segfault too. I tried also opening working image in VM marked as stable (2015-09-24), then I saved it and there was the same problem. This is probably all I know about it, although I am aware that it is not much, but I am in the dead end and this problem is really huge for me. I am on ESUG so if you are here too and think you might be able to help, I can show it to you personally.

Re: [Pharo-users] Pharo on 64bit Ubuntu

by Leo Noordhuizen

Markus, If you read the messages in this thread, you can see that it has been more or less solved. 'More or less' because Pharo runs fine now, but when I reboot Ubuntu I get a systemerror with as subject Pharo-vm. This has been probably caused by my different attempts to make this work (with different methods) which may have left some 'rubble' causing this. I should probably re-install Ubuntu soon. Which I do now and then anyway.
