[Pharo-project] [ANN] StOMP - Yet another multi-dialect object serializer

by Masashi UMEZAWA

Hello all, I have recently developed a new serialization library called StOMP(Smalltalk Objects on MessagePack). http://stomp.smalltalk-users.jp/ StOMP is a binary serializer for major Smalltalk dialects. For those who know SIXX, StOMP can be seen as a binary SIXX. While SIXX represents object data as XML, StOMP uses MessagePack. By combining the flexibility of SIXX with the compactness of MessagePack, StOMP aims to be a unique, next-generation portable serializer for Smalltalk. Features: - Implementation is compact and portable - Shared/circular references support - "Class shape changes" support - Data is interchangable between Smalltalk dialects - Good performance for small sized object graph StOMP is now available for Squeak, Pharo, and VisualWorks. There is ConfigurationOfStOMP, so the installation is easy. Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfStOMP'; load. (Smalltalk at: #ConfigurationOfStOMP) perform: #load. Enjoy! -- [:masashi | ^umezawa]

Re: [Pharo-project] About not using full Pharo

by Mariano Martinez Peck

Hi Damien. That peolpe are NOT using PharoDev is something really good from my point of view because: 1) it means that we have a set of external packages that can be loaded and work in a PharoCore 2) it is easy to manage them (otherwise they wouldn't do it) I think there are important "new" reasons why people can *now* build they own images: a) Metacello existance b) There are configurations for almost all needed projects/packages c) Jenkis d) New and easy Settings browser With all of the them is it TRIVIAL to automatically build your own PharoDev image, where you put what you want, you set the settings to want, etc. But for all the rest of the people, you have PharoDev :) Cheers On Sun, Jun 19, 2011 at 10:38 PM, Damien Cassou <damien.cassou(a)gmail.com>wrote: > Hi, > > I've read that some of you are installing their own set of packages on > top of Pharo-Core and not using Pharo.

[Pharo-project] About not using full Pharo

by Damien Cassou

Hi, I've read that some of you are installing their own set of packages on top of Pharo-Core and not using Pharo. Why is that so? What don't you like in Pharo? Why didn't you tell us before? If we don't have this information, you might not like the new Pharo-Core and you will have nothing anymore to base your images on. Speak now or forever hold your peace :-) -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them."

The server part is kept relatively simple: the server does multithreading, connection handling, request parsing and response writing and then asks its delegate to do the work, using #handleRequest: which is given a ZnRequest as argument and is expected to return a ZnResponse. The code doing the #handleRequest can be simple, like in the examples that are included, but could become arbitrarily complex, like Apache. Anyone is free to build on top of Zn whatever they think makes sense, most of this will probably be more application specific and hence out of the scope of Zn. The Seaside adaptor is a good example: it is an add-on. Seaside expects very little from its servers and Zn is offering slightly more than needed. Still, the Seaside experience is quite rich to say the least. I don't consider Swazoo or Comanche competition, they offer more features but also specific API's. Another goal of Zn is understandability: I would like the Zn code to be readable by anyone interested in HTTP. Sven
