wsdl webservice from pharo
by Pablo R. Digonzelli Feb. 4, 2015

Feb. 4, 2015

Hi all, i need to know if it is possible to consume a wsdl webservice from pharo. It is very easy using python and suds but i want to consume the webservice directly from pharo. TIA Ing.

Installing GToolkit
by Evan Donahue Feb. 3, 2015

Feb. 3, 2015

Hello, I am trying to check out GTPlaygroundl, but I can't seem to get it working and was wondering if anyone had any idea what I might be overlooking. I download a new image with curl get.pharo.org | bash I run, from http://www.humane-assessment.com/blog/installing-gtoolkit Gofer new smalltalkhubUser: 'Moose' project: 'GToolkit'; configuration; loadDevelopment. #GTImageSetupCommandLineHandler asClass new activate It loads for a while and then the image closes. When I open it again the background is white and my settings have been wiped. The playground does appear, but it doesn't seem to work properly (there seems to be no way to advance the miller columns). Am I looking at the wrong installation information? Thanks, Evan

NumericalMethods and SciSmalltalk

I have an application that uses DhbNormalDistribution from NumericalMethods in Pharo 3. Will in the future NumericalMethods be integrated with SciSmalltalk?

High precision arithmetic
by Pierre CHANSON Feb. 3, 2015

Feb. 3, 2015

Hi everyone, I was wondering if there was a package to manipulate floats like the MPFR library in C... Then I found in http://stephane.ducasse.free.fr/Web/Draft/Float.pdf that using ScaledDecimal allows exact arithmetics. So I guess ScaledDecimal is the best class to use for playing with 20 decimals numbers ? :) Thanks ! Pierre

It is a tool for building ui. some ui access source code, some don't. You can build widgets accessing something else than source code. Note that as long as the user can execute a doit, he can access your source code by guessing a class/method name. Consider the other frameworks for building ui on top of morphic too: Spec, a ui descriptor framework allowing you to deploy on morphic and on native uis Glamour, a framework for fast ui implementation > Thanks > Francis Best Clement

[ANN] PUnQLite NoSQL database project updated
by Torsten Bergmann Feb. 2, 2015

Feb. 2, 2015

Hi, are you in need for really simple out of image persistency? If you like to use a small RDBMS solution with Pharo then there is the embeddable SQLite shared library and NBSQLite3 project [1] to access it. Combine it with Glorp [2] and you do not have to fight too much with SQL. On the other end of persistency world there are the so called "NoSQL databases" and beside Mongo and all the others that require special setup etc. there is this wonderful small UnQLite embeddable database [3] that similar to SQlite world only requires a simple library. Thanks to Masashi Umezawa there is a nice wrapper for Pharo already to access this tiny embeddable NoSQL database called "PUnQLite" [4] and [5], also including access to the Jx9 machinery of UnQLite. It is really cool that he made this available. This week I updated "PUnQLite" a little bit: - refactored the Native boost wrapper for UnQLite (using shared pools, ...) - documented classes - added a help topic - fixed a bug in cursors when accessing the keys in an empty database - and finally added a small spec based tool to work with a database file (see attached screenshot) One can use it to open an unqlite database, show the key value pairs and remove or add entries. If you are in latest Pharo 4 already you can load all of that right from the config browser. Be aware that you need the external unqlite shared library which is downloaded and extracted into a folder "pharo-vm" when loading the config. For instance on Windows it automagically downloads a file "pharo-vm/unqlite.dll" below your image directory and you just have to copy this shared library file to the folder where your VM (Pharo.exe) resides. Havent tried on other OS platforms. >From the Pharo side using the UnQLite database basically works like having some kind "external dictionary" in a database file. Just run that in a workspace: |db| db := PqDatabase open: 'comments.db'. db disableAutoCommit. db transact: [ Object subclasses do: [:cls | | key | key := cls asString. db at: key put: cls comment ] ]. db close. Then open the "Database Browser" from the world menu and open the "comments.db" file. You can browse the keys and values, remove entries or add new. A filter for the keys is also included. Nothing fancy but hope you like it or find it usable. Couldnt make it to PharoConf 2015 but I hope all participants enjoy their time there. Keep the others updated by using the #pharodays2015 on Twitter. Have fun! Bye T.

Problem due to deprecation of class Url in Pharo 3 and Moose 5.0
by PBKResearch Feb. 2, 2015

Feb. 2, 2015

Hello I have run into a problem in moving some existing work from earlier versions of Pharo/Moose. I have found a work around, but I wonder if there is a tidier way of handling it. I make frequent use of Todd Blanchard's HTML parser and validator, HTMCSS (http://smalltalkhub.com/#!/~ToddBlanchard/HTMCSSValidatingParser) which was originally written for Squeak but has performed without trouble on earlier versions of Pharo. When I try to use it on Moose 5.0, I get frequent warning messages about Url being deprecated. I have made the problem go away by commenting out the deprecation warning in Url class>>new, but I wonder what should be done on a more permanent basis. The problem arises because HTMCSS does not just parse the original HTML file; it also loads and parses any referenced CSS files. (This is a function I could do without, but I don't fancy trying surgery on a complex package where I only partly understand the workings!) It constructs the full address of the CSS file by combining the root address of the HTML with the relative address of the CSS, using Url class>>combine:withRelative:, and in the course of this it invokes Url class>>new; hence the deprecation message. The deprecation message says Url has been replaced by ZnUrl, but this is clearly not a simple replacement of one message by an equivalent; there is no ZnUrl class>>combine:withRelative:, for instance. The tidiest solution would no doubt be to find an equivalent method in Zinc, which I am sure exists, and then modify the HTMCSS code to use it. I have tried to find an equivalent, but Zinc is a large and complex system and I rapidly got lost. I wonder more broadly about the strategy of deprecating functions which are required by legacy packages, as in this case. Should there at least be a way of overriding deprecations? (I suppose that is what I have done by commenting it out, but it seems crude.) Thanks in advance for any help or suggestions. Peter Kenny
