Re: [Pharo-project] Fuel - a fast object deployment tool

Hi Mariano and Martin, some feedback. The ClassPoolBindings cache in FLClassPoolAssociationMapper feels like a mistake to me. I would just compute this map at the start of serialization. It'll take hardly any time. Whereas there's lots of scope for this information, if cached, to become stale over time. Find attached. If you're happy with this then before or after remember to evaluate SystemChangeNotifier uniqueInstance noMoreNotificationsFor: FLClassPoolAssociationMapper best Eliot

Re: [Pharo-project] Report generation? (I need an update)

by Schwab,Wilhelm K

Most of my "reports" these days are graphs. Tab-delimited text -> R frequently gets the job done for publication quality work. I have various levels of control over gnuplot and PLplot; the latter being preferred with large numbers of points. I just did a rush job of knitting clashing data streams that ended with a file being imported into LibreOffice Calc and saved to .xls. A couple of years ago, I used a PDF printer driver with Dolphin to create some files I needed; that whole thing has since been folded into Seaside (great!) and then completely destroyed by what we will call politics - don't ask - nothing wrong with the science or the technology though. I have been doing a lot of writing lately. To quote a professional writer whose work I followed for a long time, "I enjoy having written". I would be going nuts were it not for LaTeX. Generating LaTeX source would be easy. Using OSProcess to run pdf2latex should be simple (I think). Formatting the output would be the most challenging part. For examples of what can be done, have a look here: http://www.cs.duke.edu/brd/NIH/tips/ and perhaps at the res.cls style. I agree that we should not try to do everything in Smalltalk, or more to the point, that we should not limit ourselves to what we have time to write. Dolphin's COM integration saved me a couple of times. Pharo should have something similar, probably centered on connectivity with Java (as a cross-platform answer to COM Automation??).

We use Jasper reports: www.jasperforge.org It's a feature-rich library for generation of any report to about any format you can think of, and it's open source. The downside is: it is a Java library but we use http communication between our Seaside app and the jasper application. In the future, I hope to get my own Javaconnect library (working in Visualworks) rolling completely in Pharo to have native communication from Pharo to Java. In the meantime, you might try JNIPort since that one has Pharo version already. We can try to develop everything in Smalltalk but we will fail to keep up. Johan

Re: [Pharo-project] Tab widget improvements

by laurent laffont

Hi Gary, I wanted to try what follows while coding TWM, maybe with your magic super powers its easy :) Create a SystemWindow subclass: #TabbedWindow (or better name). In this window's menu there's the list of all other SystemWindows. When you click on it, the window goes as tab. So I can group several windows in a tabbed container. Like the group windows feature of KDE. See http://blip.tv/sebastian-kgler/window-managing-features-in-kde-plasma-4-4-3… at 1'50. Is it hard ? Idea how to do this ? Laurent.

Re: [Pharo-project] Report generation? (I need an update)

by Otto Behrens

Hello, > So... my question: > what do you use to generate reports to clients? > if pdf generation... which strategy? We've been using http://www.princexml.com/ for some time now. We generate html with seaside, write it to a file with the CSS and run prince on it. This may be a bit strange, but this tool really uses CSS nicely. We tried a few routes; what was difficult was to get something that looks good in the browser and then looks good in a PDF document as well, with minimal effort. The + is that when developing, you can work with the browser (and write tests with SeasideTesting) and then the last step is to get pages, headers and footers to look good in the PDF. HTH Otto
