This works pretty much like PostgresV2, though some method names are different, but if you know how to use PostgresV2, then you will find out in 5 minutes how to use this. A higher level API is the PG3ConnectionPool which implements a simple connection pool. It's fairly easy to use the pool too. In 10 minutes one can set up a pool for a db without docs. The highest level API (in the public repository) is the PG3FunctionClient which allows you to call Postgres functions which return a refcursor. Most of our apps use this API to communicate with the DB. In our private repo we implemented a new high level API, which allows one to edit the Postgres functions in the Browser, fix bugs in the Debugger, version them with Monticello, etc. It also allows one to call "normal" functions which don't return a refcursor. Since the package is getting fat, we are at the point where we have to split it. When we're done with that, we'll push it to the public repo. > So feel free to experiment with it and if you need a feature or found a bug, let us know. OK, thanks for the update. I am mostly interested in plugging it under Glorp, I guess PG3Connect will do then. It is not high on my list, but I might get to it one day. Sven

[Pharo-project] A look at seaside and pharo from a Rails/Ruby perspective

by Marcus Denker

Hi, It's always interesting how things are seen from the outside... (from http://on-ruby.blogspot.com/2010/08/rubyweb-interview-with-pat-maddox.html seems there will be a talk about seaside at a ruby conference early september...) --> begin quote Seaside is interesting technology, how did you discover it? ------------------------------------------------------------ Pat Seaside is a fascinating and fun technology!! I came across it a few years ago, not long after I got into Rails. Over the years I had a couple of false starts with it...it's a bit opaque at first because the development environment is so different from anything I'm used to. And it's only fairly recently with Pharo that it's become easier to get started, because it's such a clean environment geared towards development. Also the documentation for both Pharo and Seaside are getting really good. There are free books on each at pharobyexample.org and book.seaside.st/book. Okay as for what's so interesting to me about Seaside... it's 50% the framework and 50% the Pharo environment. Seaside itself represents a step forward in web development similar to how Rails did. Rails takes care of a lot of the plumbing for you - you don't have to parse query params, set up response headers, manage the session (unless you want to of course). Seaside does all that of course but also manages application state for you. So you don't have to worry about putting stuff into a database, then pulling it back out and operating on it. I can't do it justice in a few sentences, but that's why I'll be showing lots of examples at the conference! :) At any rate, that same feeling you get when you code Rails for the first time and see how much easier things are, you get that same feeling with Seaside. It's not a replacement for Rails by any means - Rails definitely has a sweet spot, particularly when it comes to RESTful websites and interoperability with the unix ecosystem - but for the things that Seaside is strong at (which for me so far has been complex and/or configurable workflows), it runs circles around everything else. The other thing I'm loving about Seaside development is Pharo, an open-source smalltalk environment. Smalltalk is a great language, and Pharo has great tools that allow you to discover everything in the system. Honestly it makes RubyMine or etags look plain silly. The best bit is that nearly everything in Pharo is implemented in smalltalk, including all of the tools. So if you want to see the mechanics of a refactoring tool, and even build your own, it's trivial to do so, because it's just smalltalk code. Wow this answer got long. I could go on all day about this stuff. Gonna stop now. --> end quote -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

Couldn't our port of WebClient-Core be made compatible with both 1.1 and 1.2 ? It's bad enough that the original author is not really interested in the Pharo port, but we should at least work together. Sven

I did a short test with Seaside. It did not crash and all tests are green. Rendering is about two to three times faster which seems to be in line with the performance gains other people report for other applications. Cheers Philippe

Some context for other people: The patches make Seaside on WebClient and Websockets work in Pharo 1.1 without any overrides or loading any other code. Currently I'm down to one multipart test failure. Cheers Philippe
