Re: [Pharo-users] PharoJS

Norbert: I appreciate you explanation of Amber and PharoJS. I feel at a lost understanding the plethora of Smalltalk + Web frameworks. Is there a place where there is a pros and cons comparison of frameworks: Seaside, SqueakJS, PharoJS, Amber, Caffeine, VisualWorks Appex, Illiad, Aida, Teapot, etc? The sheer number of frameworks just makes it difficult for anyone to commit. It is terrifying. Can we discuss and consolidate the best features into one or two and kill the rest?

If one does Angular, one does it the Angular way, typescript and all. There is little point in doing PharoJS in Angular. Amber and Angular is also hard to do. Another issue with Amber is that it "compiles" to JS, and there are a ton of hard to read context handling code (try to debug that in a js debugger... ahah). For a project of mine, I can do it all Amber. Backend code is another story and frankly, a lot of *paying* customer are not caring about the latest "fad" in SPA/push/reactive/... A solid app that makes sense in streamlining a process is already heaven, and translates into cold cash. I am inheriting some code base where I see jQuery, React, Angular 1.x and some custom scripting all mixed up along with npm, bower, yarn, grunt things to do. WTF. So, customers asking for Angular. Ok, what kind of customers? Business owners? Or IT departments? I am done trying to sell Pharo to IT people. We are better off at upper echelons in the food chain. Where there is business value and speed of execution, and tangible results. I was explaining some reporting code to a Project Management Officer this afternoon. It is Pharo and Seaside. Well, he can actually make sense of what is in the code and can now come back with new ideas for value added features. Just put a halt at a strategic place and was able to inspect key business data interactively. Try that with any JS code.

Amber bootstraps a complete smalltalk system in javascript. Even the IDE is done that way so you have everything in the browser. It is a nice idea but suffers from the lack of development around the IDE. So the tools while being impressive are not pure fun to work with. That is the point PharoJS does better. It works with pharo connects to a web browser or node.js instance. It takes smalltalk code and transpiles them to javascript removing the need to have the complete smalltalk environment with the generated javascript. PharoJS uses a socket connection between the browser and the pharo image so you can inject and inspect things on the page. The code gets transpiled and transmitted whenver something changes. IMHO PharoJS lacks a definition of a browser DOM so you can develop nicer. But it is quite impressive though. Norbert

Spect TextModel with transparent background

by Juraj Kubelka

Hi, is it possible to set a transparent color to the TextModel? I want a text information that may take a few lines, that is able to wrap according to a window size. So, using LabelModel does not fit, because it does not wrap lines. But it looks like TextModel always looks like text editing area. Any idea how to do it? I have tried this: TextModel new text: 'any very very very long text that does not fit to one line'; color: Color transparent; disable; openWithSpec. And it does not work. Ideally it should look like the label model, but with wrapped text: LabelModel new label: 'any very very very long text that does not fit to one line'; openWithSpec Also, executing this: TextModel new text: 'any very very very long text that does not fit to one line'; color: Color transparent; borderColor: Color blue; borderWidth: 50; disable; openWithSpec. It looks to me, that color, border color and width are not reflected. Is it a bug? Thanks! Juraj

Re: [Pharo-users] PharoJS

by andrew glynn

Smalltalk does have a killer web environment, it's called Seaside. I haven't come across any good reason jQuery with Seaside isn't sufficient to do anything a developer might want to - that customers want Angular isn't based on anything that can't be done without it. Unfortunately technology is mostly chosen as if it were a combination fashion show and popularity contest, because the majority of decision makers don't understand any of it. If you really want a better web development environment, you need a better runtime environment than current web browsers. -----Original Message----- From: askoh [mailto:askoh@askoh.com] Sent: Thursday, June 22, 2017 10:41 AM To: pharo-users(a)lists.pharo.org Subject: Re: [Pharo-users] PharoJS There seem to be some interesting work with SqueakJS by Craig Latta. https://thiscontext.com/ I hope Smalltalk of all dialects can get together to develop a killer web development environment.
