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

by Matthieu Lacaton

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. If you want to fix it locally, just go to phratch directory, in locale directory, open the es.po with a text editor. search for $Strings$, and replace it with $String$. Just remove the s in fact. After that, it will work.
