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 |

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/ 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

How does it compare to Amber? Similar use case?

Hi Noury,
thanks for the feedback. For windows to open a URL one can use:
NBWin32Shell shellOpen: 'http://www.google.de'
I adopted the
startJavaScriptInterpreter
|url| url := 'http://localhost:', self port asString. Smalltalk os isWindows ifTrue: [ ^NBWin32Shell shellOpen: url ]. OSProcess command: 'open ', url and run
workspace := JbWorkspaceForWeb open. It basically runs (still throwing some Zinc errors - but I can push some eval scripts to the browser
(Chrome). No time today to look deeper today.
Please add me as a contributor so I can provide the fix/fixes or make the repo public (if possible).
Thanks
T.

2015-07-15 12:34 GMT+02:00 Sean P. DeNigris <[hidden email]>: Noury Bouraqadi-2 wrote The resulting application is the same in PharoJS and Amber, you have javascript files to deploy only and no dependence with Smalltalk, so I'd say similar use-cases for sure. I've just tried PharoJS and the main difference with Amber is that you develop from Pharo instead of from the browser, allowing to reuse the Pharo IDE for development instead of building a new one. In fact it is the same as Amber's sub-project Nemo where you develop in Amber from Pharo. Why doesn't PharoJS use the Amber compiler to compile from Smalltalk to javascript and the Amber kernel to map native Javascript objects ? Amber's compiler and JS kernel were polished and optimized during years, I don't understand why you need to do it again ... It's really nice to be able to develop and commit from Pharo.

Thanx Torsten for the fix.

Hi Noury, Thanks for the link to the documentation. I have managed to get up and running now - very cool! One question. When I execute 1+1 on the Pharo (pink) playground, I see the code appearing in the web browser log, but it doesn't appear to execute. Is it supposed to, or at this stage is it just showing that it made it over to the web browser? Cheers Andy |

That would be ideal. Otherwise the door is opened for people searching for something like SqueakJS on Pharo to be confused. They get excited they found it, then disappointed it wasn't what they were looking for. An alternative could be PharotoJS :). But maybe that horse has bolted... and open source implies those that do the work get to make the choices. cheers -ben > Unfortunately Noury Bouraqadi now took this "PharoJS" name for his > Pharo -> JavaScript compiler |

You can try to call native javascript object to see stuff changing. For example, you can evaluate the following> console native_log: 'Hello from Smalltalk'.

"Opens an alert window on the browser" Note: You need to load version 51 (just pushed it to SmalltalkHub) that fixes a bug in the PharoJS workspace. Noury |

Wow!!! That is my main pain point with Amber. Unless one is very disciplined with TDD, the linkage between the app loaded in the browser, and Helios loaded in a separate window, introduces a run-compile-like cycle where after every change, one has to reload the app which reloads the IDE, and you lose all current state e.g. workspaces, etc. How mature is PharoJS? Is anyone using it in production? Who are the core developers? What are the intentions e.g. toy? experiment? production-quality? next big thing?
Cheers,

As I showed at ESUG (we missed you BTW), it allows building a simple form app for smartphones using PhoneGap. So, I shifted my goal, and decided to make it clean and usable for production-quality app. Fortunately, I won't be alone. Torsten Bergmann and Dave Mason kindly offered their help and joined the project since few days. Regarding the status, PharoJS is usable, but I don't recommend to use it for production right now. It is not polished and parts are likely to dramatically change in the forthcoming weeks. We also need to expand the documentation. Lot of stuff to do, but I'm very excited about it :-) Still, you can give it a try. There is a first tutorial that gives a quick overview. More to come. Noury |

Ah, very cool use case. Is there a video? I just got married, but hopefully will be back next year. Much of my work seems to be converging and I hope to be able to show something exciting next ESUG :) Very good to hear on both counts. I will do that
Cheers,

The only connection is that they share the same goal of converting Smalltalk code to JavaScript.
