DataTables jQuery plugin for Seaside and DTMagritteReport
by Esteban A. Maringolo Sept. 18, 2014

Sept. 18, 2014

Hi folks, This mail is just a heads-up to anybody already using DataTables (https://datatables.net/) or that developed a Seaside wrapper for it. I just uploaded my initial working version of DataTables to STHub. If your current wrapper is better than mine we can merge our efforts. This initial version supports the basic features to instantiate a DataTables jQuery object, plus support for AJAX+JSON responses and also Server-side Processing (https://datatables.net/manual/server-side) I still have to write a proper example of how to use it, but if you load the DataTables-Magritte package it will include a DTMagritteReport that you can use to replace the "stock" MAReport. Once I have time I'll try to set up an example to show the different ways it can be used. Meanwhile look at the DTMagritteReport class to see a particular use case. It includes support for server side sorting (multiple columns), filtering, pagination, search. To load it with all the dependencies run: Gofer it smalltalkhubUser: 'emaringolo' project: 'DataTables'; package: 'ConfigurationOfDataTables'; load. (Smalltalk at: #ConfigurationOfDataTables)project development load: 'Magritte'. The STHub is: http://smalltalkhub.com/#!/~emaringolo/DataTables/ Regards! Esteban A. Maringolo

Voyage, selectMany with multiple Root
by gonza Sept. 18, 2014

Sept. 18, 2014

Hi people, I've been making a small project using Pharo and Voyage, and everything is going well, but I'm facing a performance issue when retrieving items from Mongo. I've two classes, one for items, and other for users, and both are Root. Each item contains the user who created it. My question is if there's a best way of querying all items for an user, using selectMany, when you have a document containing another. As work-around, by now, I'm making a selectAll and then filter them on memory, and that takes a lot of time and memory when the collection grows. Can you help on this? Thanks, Gonzalo -- View this message in context: http://forum.world.st/Voyage-selectMany-with-multiple-Root-tp4778705.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

STON: Metadata of text and yaml translations
by Offray Vladimir Luna CÃ¡rdenas Sept. 18, 2014

Sept. 18, 2014

Hi, Finally, with help in the Moose mailing list (thanks Doru!), I have automatic update of nodes in my outliner, and its working pretty well. I'm using STON for persistence and I see that when I update a node body content I got a lot of metadata on the text like runs, text font, text color, lastIndex, lastOfset. For reference I have attached two files, test.1.ston which is the original outline with no updates on nodes and test.2.ston which contains the updated nodes with metadata. So my questions are: 1. There is any way to exclude the text metadata or to select the "deepness" of the exportation, including just the content of the text, but not the metadata of it? 2. I see that there is a way to export from STON to JSON. There are plans to implement something like YAML[1] export? If not, which would be a good approach to explore the existing code on STON-Core and implement this? 3. I have seen that text string containing a carriage return are stored with "\r" character in them, there is any way to make the text be stored containing actual carriage returns? [1] https://en.wikipedia.org/wiki/YAML Thanks, Offray

[ANN] SortFunctions (Multiple criteria sorting)
by Esteban A. Maringolo Sept. 17, 2014

Sept. 17, 2014

After the discussion about multiple sort criteria [1] I decided to make some modifications I was needing, and also repackage the initial port Nicolas Cellier did. The result is the transformation of Nicolas' TAG-SortFunctions [2] "experiment" to a first class project plainly named 'SortFunctions' available at: http://smalltalkhub.com/#!/~emaringolo/SortFunctions/ Nicolas said: "Since I got absolutely zero feedback after a long thread, I assumed it was not interesting anybody... But my personal opinion differs: this should be included in each and every Smalltalk." I sorry for not replying before, I also think this kind of features should be easily discoverable in a default image, and that's why I built a Metacello config to be included, maybe, in the MetaRepo. Credits were preserved in the STHub project site both for Travis and Nicolas. Best regards, Esteban A. Maringolo [1] http://forum.world.st/Has-someone-ever-built-a-sort-block-generator-tp47712… [2] I guess TAG is for Travis A. Griggs
