Hi - When I run this: Gofer new smalltalkhubUser: 'YuriyTymchuk' project: 'Configuration'; configurationOf: 'Vidi'; load. #ConfigurationOfVidi asClass loadStable I get a error that the 1.2.14 version of ConfigruationOfRubric cannot be found. The ConfigurationOfRubric is loaded from the MCSmalltalkhubRepository owner: 'AlainPlantec' project: 'Rubric' user: '' password: '' repo. Is there another one it should be loading? Thanks Paul

Font with many Unicode glyphs to display code -- IPA?
by H. Hirzel July 30, 2015

July 30, 2015

Hello I work on an app which has some strings in the code with a considerable number of non ISO8859 symbols (e.g. IPA https://en.wikipedia.org/wiki/IPA) How do I get / use a font which does this? The fonts provided in the settings panel did not do the job. Thank you in advance --Hannes

Script of the day

Hi! Just to share a couple of experiment. I have tried the following in a playground: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= b := RTMondrian new. b shape rectangle if: [ :aFile | aFile path basename beginsWith: '.' ] color: Color red. b nodes: FileLocator documents allChildren. b edges connectFrom: #parent. b normalizer normalizeSize: #size using: #sqrt. b layout tree. b -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= It shows a tree of the file system. Thanks to GT, simply clicking on a file may show you the content and other things. You can also use the cluster layout: I have tried this on OS X, since the pointed folder is ~/Documents. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Hi I know that Olivier Auverlot has all kind of string distance. Hernan Morales has also a package extending string. Stef

New methods for the String class
by Daniela Meneses July 28, 2015

July 28, 2015

Hi to all, As you may know I'm working on in some improvements for the String class. Until now I implemented some missing tests. Right now I'm looking forward to add new methods that could be useful based on Ruby API ( http://www.ruby-doc.org/core-2.1.0/String.html) These are a few of the methods that I'm planning to implement: - chomp(separator=$/) -> new_str - chop() -> new_str - ljust(integer, padstr='') ->new_str - next -> new_str - partition(sep) -> [head, sep, tail] Could you help to find out if these methods are already available for the String class? If you have any idea of new methods for the string class, will be really welcome. -- Cheers , Daniela Meneses

Glamour Table action on single cell?
by Gareth Cox July 28, 2015

July 28, 2015

Hi Again I'm wondering if its possible to have a double click (#strongSelection) action on single cells within a composite table. Basically I'd like to double click a value and be able to edit it (by whatever means I deem necessary). A lot of this is because I have a need to deal with unknown data, unknown values, in sets of unknown sizes. I'm trying to build stuff to be as dynamic as possible. So given the below example, are there any suggestions on how to add actions to single cells? |browser aCollection firstDict secondDict thirdDict| firstDict := Dictionary new at: 'name' put: 'john'; at: 'surname' put: 'blogs'; at: 'age' put: 33; at: 'location' put: 'everywhere'; yourself. secondDict := Dictionary new at: 'name' put: 'mary'; at: 'surname' put: 'jones'; at: 'age' put: 25; at: 'location' put: 'nowhere'; yourself. thirdDict := Dictionary new at: 'name' put: 'steve'; at: 'surname' put: 'irwin'; at: 'age' put: 51; at: 'location' put: 'somewhere'; yourself. aCollection := OrderedCollection new add: firstDict; add: secondDict; add: thirdDict; yourself. browser := GLMTabulator new. browser column: #table. browser transmit to: #table; andShow: [ :composite :collection| |aTable| aTable := composite table. collection first keys do: [ :key | aTable column: key evaluated: [ :each | each at: key ] ] ]. browser openOn: aCollection Many Thanks -- Gareth Cox IT Manager/Developer Inspired Org (PTY) Ltd email: gareth(a)inspired.org <mailto:gareth@inspired.org>

Loading code from a local git repository
by Tommaso Dal Sasso July 28, 2015

July 28, 2015

Hello, I am trying to version a project on git using filetree. Since I also have some external resources (like images), I would avoid loading the whole project from the pharo image, because that would download the external files in a cache directory, thus making them difficult to reach and update. My idea is to update the git repository from the commandline, and then run a script to build the image. The question then is: is there an easy way to programmatically load a project from a local directory? Also, do you have any suggestions for a better workflow to handle this situation? Thanks, Tommaso
