I guess I'm knowledgable enough to answer this: a) it is useful b) if it is easy depends on where you get the description info from c) Do not dicusss, stop lamenting and help coding :) When I wrote the config browser there was no central way to find out which packages/configs are working for which Pharo version. The easiest thing that could possibly work was to create a MetaRepoForPharoXXX repo for each version XXX of Pharo and copy the working configs into it. The tool just queries the list of available file names and displays them. For the initial step this was enough and still good enough that the tool opens quick enough. If you would LOAD ALL the configs in such a meta repo BEFORE OPENING into the Pharo image to extract more informations (like descriptions or dependencies) the config browser would be unusable due to bad performance of such operations. This could be solved by caching, but so far there was no time. Additionally as it makes sense to store such descriptions with the config Stef implemented Catalog. Some ConfigurationOfYYY classes have such meta data for Catalog and the project currently produces an HTML report: https://ci.inria.fr/pharo-contribution/job/PharoProjectCatalog/HTML_Report/ One must know about this. Not ideal - but a step forward to at least make it visible somehow. Several options: ================ 1. Implement a solution to load all the config in the meta repo into the image, extract the data the first time and write this info to a cache. Update the cache on request. It MUST be cached, otherwise it will burn CPU cycles. Although this cache can be shared between Pharo image with the same version I think this is not ideal. 2. Using Stefs "Catalog" project one could (beside the HTML report) provide something that is easy to parse from the tool so we can load the contents of the displayed list from the web quickly When the CI runs often it should be up to date always - but we must make sure such a job is never broken. Would be a better option - but also needs someone to do that. 3. In the long term: Implement a better online mechanism to register Pharo related stuff. Some kind of PharoStore where you can register and share Packages but also other things like tutorials, articles, video, wallpapers, ... Then the client can query for this info (maybe using Spotter) and just load. Feel free to shape/code on improving this. There is something in the pipe for 3. from my side already, but only slowly progressing maybe too much work for one person. If you want to help and know Pharo and Seaside very well then contact me offline.

Datathon for development in Paris
by Serge Stinckwich March 13, 2015

March 13, 2015

Dear all, something that might interest some of you. There will be a datathon organized in Paris in collaboration with the MIT about data & development in African countries from April 7th to 9th. Some companies and NGOs will provide open data. Orange, the telecom provider will provided some data about communication between local antennas and also trajectories log of people. I have the idea of having a small team using ROASSAL for participating to the datathon and doing some nice vizualisations. Anyone interested to made a team ? You could find more information about this event here: http://simplon.co/blog/2015/3/7/datathon-data-for-development-rdv-les-7-8-e… sorry only in French.

configuration browser descriptions
by Sebastian Heidbrink March 13, 2015

March 13, 2015

Hi! Here is another information based on my last beginners session. One should discuss if it might be useful and easy to implement to have a configuration browser that includes descriptions for the offered configurations. Beginners have no idea what Seaside, AltBrowser, Artefact,... stand for. Cheers! Sebastian

Question about NeoJSON
by Mariano Martinez Peck March 13, 2015

March 13, 2015

Hi, In this link: https://github.com/svenvc/docs/blob/master/neo/neo-json-paper.md I see an example of a custom mapping like this one: mapper for: TestObject do: [ :mapping | mapping mapInstVars: #(id name). (mapping mapInstVar: #timestamp to: 'created-at') valueSchema: DateAndTime. (mapping mapInstVar: #points) valueSchema: #ArrayOfPoints. (mapping mapInstVar: #bytes) valueSchema: ByteArray ]. I need something similar, but I need to store the original JSON string that was used to build a particular TestObject instance, in an instance variable of TestObject too. In other words, I need an instVar "originalResponse" in TestObject that would be set with the original JSON string. Any ideas how can I implement this? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

When to use a stream for concatenating text..
by sergio_101 March 13, 2015

March 13, 2015

it seems that in more cases than not, i find that developers use a stream when concatenating some text strings. I am wondering if this is a smalltalk thing, or is there a real speed benefit when using streams in this way. Thanks!

Notebook/slideshow morph
by Torsten Bergmann March 13, 2015

March 13, 2015

>So I imported my old code (it was one week of test first experience). >I can open a slideshow, create page, drop morph on it, mark a page as >template and navigate. Is there a way to save and reload the slide show. Like in the good old squeak days (TM) with a *.morph file? Would be a nice addition to recreate some of the presentation and multimedia features known from Squeak now also in Pharo. Thanks T.

Settings Browser: Moose 5.1 exported settings raises error in Pharo 4.0
by Juraj Kubelka March 13, 2015

March 13, 2015

Hi, If I export settings from Settings Browser in Moose 5.1 and then open Pharo 4.0 image, it raises an error "GTGenericStackDebugger not found in SystemDictionaryâ. The problem is a setting: (Smalltalk at: #GTGenericStackDebugger) perform: #enableStackColoring: with: (true) which apparently does not exists in Pharo 4.0. I think if we want to share settings between images, it should ignore any setting that raise an error, right? Thanks! Juraj

I think phil is right. -vm-display-null is the question . it aborts the process. Does not matter wich vm and image are you using. For example i am trying pharo4 latest image latest vm. TIA Ing.
