Re: [Pharo-project] reading *exactly* n bytes from socket

by Schwab,Wilhelm K

I don't just write English, I also write Smalltalk :) I had put some related code on SqueakMap, but I suspect it disappeared in one of the meltdowns. It also picked up some code that I had not intended to release, which led me to be unhappy with http repositories. The code varies in quality, covering things missing in streams, FFI, value adapters, among other things. I recently noted that the FFI code will require tweaking to be of use with 1.3 and up.

When I know that the next packet of data from the server is going to be 10'000 bytes I want to ask the socket for exactly 10'000 bytes of data (I don't care how long it takes). However, the comments in the Socket class suggest that the buffer might not be filled entirely when the message answers.

And from your box you are trying to look at Smalltalk and trying to shape it to your experience and thusly declaring its deficiencies. This does not make Smalltalk wrong. Most of us here like the Smalltalk experience. We like the language. We like the image. Are there issues that we would like to overcome? Of course. Outside of interfacing with the outside world being made easier, I don't think you are really addressing those issues. Instead, your are creating issues we don't have.

Please feel free to do so. It is open source. Fork it and make it so. We would even help where we are able. But you are going outside of the vision and worldview of this community and most any Smalltalk community. Cincom, Gemstone, or any of the other commercial Smalltalks have reasonable success despite all the deficiencies you have discovered. And if you decide that Smalltalk doesn't fit your worldview. That is ok. Find the tool that fits you. Be productive with it. And if you want to create what you think is a better way with what you learn from Smalltalk. Go for it. As far as GUI. I like ours. I think it can be improved greatly. But I like access to it as part of my environment. What is a standard UI? Who set this standard? Why is QT standard? or WxWidgets or ...? Look at the most used apps out there. Are they using native standard UI? I don't think so. iTunes is a hugely used app. Is it standard UI? No. Apple Mail? Safari? Windows Media player?

So, in this statement, by definition you are moving from the most standard defined UI to lesser standard UIs. Linux is all over the map. The above are simply my opinions and I make no express statements that anyone else in the Pharo community agrees with them.

[Pharo-project] [ANN] Amber Smalltalk 0.9.1 is out!

by Nicolas Petton

About 4 moons have passed and Amber - the Smalltalk for the web - has during that time moved forward quite a lot. Since the 0.9 release back in september we have made about 250 commits and closed 52 issues of about 75 reported during these months. Now with over 43 forks on github and more than 230 followers the project: http://www.amber-lang.net ...is live and kicking! A lot of cool stuff is being done in those forks and not in the master repository, like for example the gaming framework called Ludus by Bernat Romagosa: https://github.com/bromagosa/amber/tree/ludus ...or Ambrhino by Stefan Krecher - Amber running in Rhino: https://github.com/StefanKrecher/Ambrhino So, why would you take a look at Amber? In our opinion Amber is perfectly positioned for the HTML5 onslaught and the explosion of all-things-javascript like for example Nodejs. Amber plays very well with others and can seamlessly use Javascript libraries! It's a *real* Smalltalk, the environment is all there including Workspace, Transcript, Browser, senders/implementors/references to class, TestRunner, Inspectors, code editing with syntax coloring and a Debugger. There is no image or interpreter, all compilation is incremental. JavaScript is quite a broken language with lots of traps and odd quirks. It is the assembler of the Internet and we love it for that, but we don't want to write applications in it. Smalltalk is immensely cleaner, both syntactically and semantically with a simple class model and a lightweight syntax for closures. It is in many ways a perfect match for the Good Parts of JavaScript. And having a true live interactive incremental development environment where you can build your application directly in the browser is unbeatable... Below follows a summary of the major changes since release 0.9. We hope you join us in developing Amber and having fun! Fork at github, join in #amber-lang on freenode and hop onto the mailing list. regards, Nicolas & GÃ¶ran ...and a BIG thanks to everyone that are involved in the project! --------------------------------------------- Here's a summary of changes since the 0.9 release: - 80 new unit tests written - 52 issues fixed - All classes in Kernel-Objects, Kernel-Classes and Kernel-Methods has been documented - New documentation framework (see http://amber-lang.net/documentation.html) - Better class organisations, "Kernel" package split into several packages - First class packages have replaced class categories - Internet Explorer 7+ compatibility - New Announcement framework ported from Pharo - New console-based REPL written in Amber using node.js - Symbol class implemented together with object identity and #== - New OrderedCollection and Set implementation - Dictionary can now have any kind of object as keys. String-key dictionary has been renamed HashedCollection - New TwitterWall example - Improved HTML Canvas, now compatible with IE7 - Improved JSObjectProxy for seemless JavaScript objects access from Amber - No more jQuery binding. Amber is fully capable of sending messages to JavaScript objects

Re: [Pharo-project] New IDE alternative (was Misc. newbie questions)

by Lawson English

A remote squeak image that is used to handle OpenGL calls (or other external lib calls) and pass error codes back to the main IDE might be useful for OpenGL (or other external lib) debugging. VM support could be made so that error checking could be handled below the level of the interpreter for maximum speed. A lot can be done if Spoon is ever officially embraced by the meta-squeak community (Pharo and Squeak are thus far the only members that I am aware of). L.

When I know that the next packet of data from the server is going to be 10'000 bytes I want to ask the socket for exactly 10'000 bytes of data (I don't care how long it takes). However, the comments in the Socket class suggest that the buffer might not be filled entirely when the message answers. As a consequence, my code fails because the ByteArray sometimes has a number of zero bytes at the end which obviously wasn't expected. >>>> I also tried to use SocketStream to get around this problem but wasn't successful.

Thanks Sven, I'll give it a shot.
