Running headless on Windows
by Andrei Stebakov Jan. 20, 2018

Jan. 20, 2018

When I run Pharo 6.1 with -- headless option on Windows, it executes the eval command as expected but during the execution (which lasts 4 sec) it opens the Pharo GUI. Is it expected? I thought headless means that the whole execution would happen in the background

Commander feedback
by Juraj Kubelka Jan. 17, 2018

Jan. 17, 2018

Hi, I like the idea of the Commander library https://github.com/dionisiydk/Commander <https://github.com/dionisiydk/Commander> I am trying to understand how to use it, but I struggle to understand it as documentation includes quiete complex examples: https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgre… <https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgre…> I believe that it would be useful to have a tutorial that shows: 1. create a command CmdOne including methods, 2. create a activator ActOne including methods, 3. create a context CtxOne including methods, 4. execute <I do not know what> and you obtain a collection with one item (CmdOne instance?) 5. create command CmdTwo with some methods 6. execute <I do not know what> and you obtain a collection with two items Then next section could describe how to make a UI on top of this. Learning it by exploring Calypso is too complex, because it involves more objects and I actually do not see how to do the previous steps. I will be happy to help with the documentation. My question is: How can I proceed the mentioned steps? Thanks, Juraj

[ANN] OpenSSL-Pharo works on Windows
by Pierce Ng Jan. 15, 2018

Jan. 15, 2018

Hi all, OpenSSL-Pharo now works on Windows. Tested on Windows 10 with a fresh 32-bit Pharo 6.1 zip package downloaded from pharo.org. On Windows this library uses libeay.dll which is bundled with the Pharo VM. Metacello new baseline: 'OpenSSL'; smalltalkhubUser: 'PierceNg' project: 'OpenSSL-Pharo'; load. Pierce

pharo 6.1 64bit segmentation fault on linux
by Johan Brichau Jan. 13, 2018

Jan. 13, 2018

Hi, Iâm also hitting this issue: https://pharo.fogbugz.com/f/cases/20737/Segmentation-fault-trying-to-load-c… <https://pharo.fogbugz.com/f/cases/20737/Segmentation-fault-trying-to-load-c…> Also reported here: http://forum.world.st/Pharo-6-1-64-bits-segmentation-fault-loading-code-on-… <http://forum.world.st/Pharo-6-1-64-bits-segmentation-fault-loading-code-on-…> This stops us from using Travis-CI because the OSX builds are just way too slow there. Since more recent vms are working (see thread), any chance the vm for linux is updated on the pharo site so we can use Smalltalk-CI? thx for an update Johan

A playground for Markdown?
by Offray Vladimir Luna CÃ¡rdenas Jan. 9, 2018

Jan. 9, 2018

Hi, Playgrounds are a really good way to write short snippets of code and I wonder if such experience could be extended for larger pieces of Markdown. What I'm thinking of is have something similar butÂ like this: 1. Support for Markdown instead of Smalltalk, including syntax hightlighning and tab behavior (a tab equals two spaces). 2. Clicking on urls should load the respective web page. Clicking on images shouldÂ show an image preview. That's it, to start with. At some point it could be using GT Documenter previews, font support and so on. But I would like to start by extending the playground to just support this two features. Any advice about where can I start for the first feature? Thanks, Offray

Grafoscopio (Initial) Feedback
by Sean P. DeNigris Jan. 6, 2018

Jan. 6, 2018

Thanks for this exciting project! I'm very intrigued after reading some of your blog posts because I have been actively working with big data in Pharo, but mostly by hacking/cobbling things together without a proper toolset/community. Here are a few things I noticed as I started playing around: - Maybe you should change the load command in the StHub readme to: ``` Metacello new smalltalkhubUser: 'Offray' project: 'Grafoscopio'; configuration: 'Grafoscopio'; load. ``` - the current script is in an old form - it also hardcodes Pharo 5 - This would greatly simplify the load via script instructions in the manual - Is it supposed to load in Pharo 6.1? I got `OrderedCollection DNU #asSymbol from #listOutdatedDocsIn:. I stubbed out #isUpdated to return true and it loaded. - Do you have any plans to move to git? I would love to contribute, but I've been spoiled by GH and I just don't have the energy to go back to the mcz (barrier filled) contribution process ha ha - I found the intermixing of gray and color buttons confusing. I assumed that the gray ones were disabled. - I wonder if labels on the node title and link edit fields might help discoverability - All the export formats seem to end up saving to markdown. I assumed this is because I'm missing an external library? Either way, it would be good to get some feedback on why it doesn't work as expected and how to make it work. Thanks again. Keep moving forward!! ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Is there a way to stop arrays sorting automatically?
by Andy Burnett Jan. 2, 2018

Jan. 2, 2018

I suspect I am missing something very obvious, in which case could some kind soul put me straight? I have the following code col := OrderedCollection new. (1 to: 9) permutationsDo: [ :each | col add: (each )]. I thought this would give me a collection containing all the permutations. However, what actually happens is that each of the arrays has been 'magically' sorted back into numerical order. If I change the code to read col := OrderedCollection new. (1 to: 9) permutationsDo: [ :each | col add: (each asOrderedCollection )]. Then the permutations are retained. Is this how it is supposed to work? Or, am I doing something wrong? Cheers Andy
