Its too hard to contribute to the Iceberg wiki
by Tim Mackinnon July 5, 2018

July 5, 2018

Ok - my love affair with Github ends at the wiki - what a load of $%$%^$%â¦ there is no sane and easy way to fork a wiki, make some changes and then submit a PR. (how the hell did they get into that state?). Can we agree to scrap the wiki Iceberg wiki and just have a longer readme.md (with sections of the current wiki?). Or if someone can explain easy instructions for both me (as a contributor) and the admins of iceberg then Iâm all earsâ¦. If not - Iâll submit a PR with my subtle changes to the readme. Tim

Need help to get a list of Pharo projects with tests
by Julien July 5, 2018

July 5, 2018

Hello Pharo community, I am currently working on detecting rotten tests in Pharo projects. Rotten tests are defined as test methods containing one or many assertions in their source code but one or many of these assertions are not executed when the test is run. To have more details on the subject, you can check the research report related to our first definition of these tests freely available on HAL [1]. In this context, we built a test analyser which, given a Pharo package containing tests, finds rotten tests [2]. This analyser is still under development. We would like to extend the experiment of our research report [1] and to analyse more projects in order to get a better understanding of rotten tests. To do that, we need your help. You can help us in two ways: 1. Answer this email with links to one or many open-source Pharo projects containing tests. 2. If you want, provide us private projects or, at least, run our analyser on these private projects and give us back the results. If you want to help us with the second option, send me a mail directly at julien.delplanque(a)inria.fr <mailto:julien.delplanque@inria.fr>. Thanks in advance.

Code porting to Pharo 6.1-64
by dario.trussardi＠tiscali.it July 5, 2018

July 5, 2018

Ciao, i work to port some code from Pharo 4.0 to Pharo 6.1-64. My root class into Pharo 4.0 define the properties instance variable and some relative method: a) propertyAt: aKey ifAbsent: aBlock ^ self properties at: aKey ifAbsent: aBlock b) propertyAt: aKey ifAbsentPut: aBlock ^ self properties at: aKey ifAbsentPut: aBlock c) propertyAt: aKey put: aValue ^ self properties at: aKey put: aValue d)...... Now when i port this code into the Pharo 6.1-64 when compile the code the Behavior originalName method implement: ^ (( self isObsolete and:[ self name beginsWith: 'AnObsolete ............ where isObsolete TClass is: self propertyAt: #obsolete ifAbsent: false But my class implement a specific propertyAt: ifAbsent: method and the system generates errors and don't compile the code. Thank you for every consideration. Dario

do-it or inspect-it in the spotter search bar?
by PAUL DEBRUICKER July 5, 2018

July 5, 2018

I was feeling lazy was wondered if it would be possible to hit Cmd-D or Cmd-I in the spotter input field rather than opening a playground and typing something in then hitting it. E.g. 1 + 1 Cmd-I would open an inspector on the number 2 After looking at GTSpotter>>#spotterFor... methods I couldn't figure out how to make it happen in the half hour I had to spend on it. I recognize opening the playground is Cmd-O Cmd-W but I just open the spotter ~50x as often as a new playground so the muscle memory isn't there. If I could do quick one-liners in the spotter then the playground would get opened even less often.

Hi, Iâm trying to get a video stream in Pharo from a Pi video stream using this lib on the. Pi (https://github.com/jacksonliam/mjpg-streamer <https://github.com/jacksonliam/mjpg-streamer>) Then I found this library on Pharo (from 2013). https://www.min.at/prinz/?entry=entry130413-020021 <https://www.min.at/prinz/?entry=entry130413-020021> http://www.min.at/prinz/repo/mjpeg <http://www.min.at/prinz/repo/mjpeg> I had to change a method relative to Annoucment. #on:do: => #when:do: Now I have a problem in Pharo 7 (same in Pharo 6) with ZdcSocketStream>>upToAll:limit: (see pic) TIA, CÃ©drick

Pharo 7 streams API
by Peter UhnÃ¡k July 3, 2018

July 3, 2018

Hi, I'm starting to familiarize myself with new streams, and one thing I've noticed is the removal of #lineEndConvention (which I use all the time). So a statement like this aFile writeStreamDo: [ :stream | stream lineEndConvention: #lf. stream << '...' ]. has to be written like so aFile writeStreamDo: [ :rawStream | |stream| stream := (ZnNewLineWriterStream on: rawStream) forLf. stream << '...' ]. which feels very messy because I am mixing writing with the configuration. And I don't even take account for buffered/encoded decorators. Plus it increases the incidental complexity -- I need another variable, and I can accidentally write to the wrong stream, etc. Would a method like #writeStream:do: (or #writeStreamTransform:do:) make sense? E.g. aFile writeStreamTransform: [ :stream | (ZnNewLineWriterStream on: stream) ] do: [ :stream | stream << '...' ] To separate the composition from the usage? Thanks, Peter

[ann] gt documenter
by Tudor Girba July 2, 2018

July 2, 2018

Hi, We are happy to announce a new leap of GToolkit Documenter, the tool for manipulating live documents directly in the development environment: https://github.com/feenkcom/gtoolkit-documenter Documenter is part of the second generation GToolkit project, it is based on Bloc and works with the latest Pillar. It is mainly developed by Juraj Kubelka. Attached you can see a preview of how documents look like: At its core it offers a live editor for manipulating Pillar documents. The interaction happens seamlessly directly in the text editor, and it can be combined with different types of previews to serve several classes of use cases: â¢ code documentation â¢ tutorials â¢ interactive data notebook Code documentation ---- Documenter complements the GToolkit Examples engine to redefine code documentation. When practicing example-driven development, examples get written as part of the typical development. Once examples exist, they can be quickly put together in a document to form documentation. For example, the linked picture shows the comment of a class containing a visual explanation: https://twitter.com/feenkcom/status/973899862482866176 You can see a live example of documentation by inspecting the following snippet: GtDocumenter editorForText: BrToggleExamples comment. Tutorials: ---- Documenter offers a new experience of writing tutorials for Pharo by enabling the creation and embedding of Epicea change sessions directly in the document. For example, take a look at the following animation: https://twitter.com/feenkcom/status/999975333972541440 The document shows a method on top, and a change preview at the bottom showing both the code and the associated diff to the state from the image. Applying the change updates both the change view (no more diff), and method preview. This speeds up significantly the process of going through a tutorial. Furthermore, given that now the document shows the diff to the current image, the reader can safely explore alternative scenario and come back to the tutorial at any time without losing the overview. The size of the preview can also be adjusted live: https://twitter.com/feenkcom/status/1001152789874167808 https://twitter.com/feenkcom/status/1001407762285375490 You can see a live tutorial by inspecting: IceRepository repositoriesLocation / 'feenkcom'/ 'gtoolkit-examples' / 'doc' / 'tutorial' / 'examples-tutorial.pillarâ. Interactive data notebook: ---- A Documenter document can also be used as an interactive notebook. Internally it essentially acts as a playground: â¢ it supports defining variables in code snippets, and â¢ the execution of code shows an embedded inspector. For example: https://twitter.com/feenkcom/status/996310432225820672 https://twitter.com/feenkcom/status/1002851190475026432 An example, can be seen by inspecting: IceRepository repositoriesLocation / 'feenkcom'/ 'gtoolkit' / 'doc' / 'gtoolkit' / 'gtoolkit.pillar'. As always, please do let us know what you think. Enjoy, The feenk team -- www.tudorgirba.com www.feenk.com "If you can't say why something is relevant, it probably isn't."

How to get changes applied to Pharo website?
by Tim Mackinnon July 2, 2018

July 2, 2018

Hi - what is the easiest way to propose changes to the Pharo website? Iâd like to get an id put on the <h2>Command Line</h2> section, so that we can easily link to this part of the website to send people to instructions on using the terminal? E.g http://pharo.org/download#CommandLine <http://pharo.org/download#CommandLine> Do I raise a Fogbugz? Tim
