Re: [Pharo-users] [ANN] Pharo Glorp port release

by jtuchel＠objektfabrik.de

Hi, DBXTalk is good work! I really love to see that stuff going forward! Before I spend a lot of time playing around: has anybody tried using Pharo/GLORP/ODBC (Access or SQLSrv) on Windows? Or Pharo/GLORP/SQLite on Windows? Is there some place on the web where I can find info on how to set this up? In an open source context, this is probably a heretic question, and if I could choose freely, Linux and PostgresQL would be my favorite. OTOH: The fact that each windows installation comes with an Access engine and respective ODBC driver makes the combination very attractive for starting something on a windows machine really fast. No installation of anything but Pharo, no need for admin rights or anything. Just set up the odbc driver and off you go! Great chance to show the strength of Smalltalk and Glorp to other team members and friends... SQLite is a similar story: copy the dlls onto the machine and the journey can start. Joachim

RESTful Pharo app (not Seaside)

by Sean P. DeNigris

What's the simplest/best way to communicate with a Pharo desktop app via RESTful API? Is anyone doing this? I frequently want to communicate with a running image and REST seems a little easier than XMLRPC which I've been using. I saw SimpleRestServer (http://forum.world.st/Simple-rest-server-td3571503.html) but was wondering if anyone has some good advice. Thanks.

Re: [Pharo-users] red-black and other trees

by Lukas Renggli

The BTree package contains a class called DateTree for exactly that purpose. Works very well with huge collections of date intervals.

red-black and other trees

by Paul DeBruicker

Hi - I am considering implementing a Centered Interval Tree (http://en.wikipedia.org/wiki/Interval_tree) because I have to get the set of Timespans a particular Timespan overlaps from an arbitrary set of Timespans. In looking around I can only find the BTree implementation on SqueakSource, and the Left-Leaning-Red-Black-Tree linked to in the following list posting: http://forum.world.st/Interesting-survey-about-smalltalk-tp2261561p2263370.… Does Pharo either not need/benefit from the various kinds of trees? Or is it trivial to implement/adapt the BTree to behave as a Red-Black Tree (or, in my case, the Centered Interval Tree) and as such I just need to learn how to do that? Thanks Paul

Re: [Pharo-users] Loading Seaside 3.0 cripples System browser

by Tangaloor

Well, I got past most of the RB and OB issues by doing this: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfMetacello'; load. ((Smalltalk at: #ConfigurationOfMetacello) project version: #stable) load. Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSeaside30'; load. ((Smalltalk at: #ConfigurationOfSeaside30) project version: #stable) load. Apparently, it's just a good idea to upgrade Metacello before doing anything else. Being new and using the One-Click Pharo image, I was just following the instructions that pop up when you evaluate 'DEVImageWorkspaces openExternalProjectWorkspace.' It would maybe be a good idea if the instructions were updated to recommend upgrading Metacello before doing anything else. Now, however, I'm getting this from ConfigurationOfOmniBrowser version122: SmallInteger(Object)>>doesNotUnderstand: #add: ________________________________ From: Dale Henrichs [via Smalltalk] [ml-node+s1294792n3898513h54(a)n4.nabble.com] Sent: Wednesday, October 12, 2011 10:53 AM To: Joel E.
