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

What's the status of Pharo exercism?
by Tim Mackinnon July 1, 2018

July 1, 2018

Presumably someone is working on Pharo Exercism (did I notice Ben or Hilaire asking about the tonel format for it?) Is it possible for someone to put a comment in the repo for it - so we can coordinate effort? Iâm assuming that someone can at least get hello world working as an example? It would also be handy if someone who understands how it works, can give a quick explanation here - as I would offer to suggest it as something for the next UK Smalltalk gathering next month. Iâm assuming the cli submits files to some travis runner and you get results back - and we just have to fill something in that will interpret those files and launch a command line pharo to get the results (presumably handling walkbacks in a way that the results get fed back). And then Iâm guess we have a pharo add-in that would let you do this from the image some way too? Tim

PolyMath move to github !
by Serge Stinckwich June 30, 2018

June 30, 2018

Thank to the terrific work of Cyril, all the PolyMath code is now available on github: https://github.com/PolyMathOrg/PolyMath With a lot of magic tricks, Cyril was able to preserve part of the history of the project: https://github.com/PolyMathOrg/PolyMath/graphs/contributors This is nice to all the commits that we have done sine more than 3 years, available as git commits now ! âThank you again Cyril ! >From now, we will use only github for the commits. You will have to use Pharo 6.1 or Pharo 7.0 to use Iceberg.â I will prepare a guide for contributing to PolyMath soon. ââ -- Serge Stinckwich UMI UMMISCO 209 (SU/IRD/UY1) "Programs must be written for people to read, and only incidentally for machines to execute."http://www.doesnotunderstand.org/

Tonel Fileout
by Ben Coman June 30, 2018

June 30, 2018

How can a fileout/filein be done using Tonel format? In the first case as a script? and secondly as a possible menu option for Pharo? This is to facilitate transfer of student coding exercises for Exercism. http://exercism.io/languages/pharo/launch Could Tonel handle a full package export in one file? cheers -ben
