remote development via VS Code
by Ben Coman June 9, 2017

June 9, 2017

I just bumped into Microsoft's MIT Licensed IDE "Visual Studio Code" that runs on OSX, Linux & Windows. What is interesting is their Debug Protocol for connecting to language specific debuggers. * https://code.visualstudio.com/docs/extensionAPI/api-debugging If I had time, it would be interesting (and super cool) to build a Debug Adaptor in Pharo * https://code.visualstudio.com/docs/extensionAPI/language-support as well as a Language Server Protocol provider * https://code.visualstudio.com/docs/extensionAPI/language-support Could make a good student project or two. The skills learnt and demonstrated would be quite marketable outside of the Pharo community. >From a marketing perspective, it might be more palatable for existing Visual Studio users to install Pharo as an extension rather than install Pharo as a whole new IDE (i.e. Pharo) - a common complaint about Smalltalk in general. At a minimum there is the exposure gained from Microsoft's Extension Marketplace, with early adoptors trying out Pharo just-because-its-there. It also smashes that regular criticism of Smalltalk that it lives too much in its on isolated world. It might attract developers wanting to do polygot development, for example (just guessing that might be possible): * game development using Unity libraries for the game engine with Ronnie's minimal-vm embedded as the scripting language, and debugging both in parallel from a single environment * Pharo web server backend with Javascript frontend I vaguely wonder if it would be possible to make a Debug Adaptor that integrates VM & Image level debugging, transparently stepping from Smalltalk into the VM C code. That could be useful for FFI debugging, or developing low-level graphics interfaces that might break our internal IDE. Disclaimer: Like all my random ideas, its a bit vague and dreamy, but I had no concept of it yesterday, so just sharing the find to stimulate future ideas. cheers -ben

GSoC Week 4 Update - Enhancing Pharo Command Line Interface
by Rajula Vineet June 8, 2017

June 8, 2017

Hi, This week I have integrated the new implementation and I tested if all the current tests are running fine. The new implementation works fine. I need to write a few unit tests and then I am looking forward to integrating this into Pharo. And this week I have written a blog post <https://vineetreddy.wordpress.com/2017/06/08/filesystem-and-its-internals/> on filesystems. It is a brief post. Do take a look and give your feedback. Thanks, Rajula -- View this message in context: http://forum.world.st/GSoC-Week-4-Update-Enhancing-Pharo-Command-Line-Inter… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

DiskStore question
by Rajula Vineet June 8, 2017

June 8, 2017

Hi, I have been looking at the DiskStore class and I came across the method defaultWorkingDirectory. defaultWorkingDirectory | pathString | pathString := Primitives decode: Primitives imageFile. ^ (self pathFromString: pathString) parent I didn`t get the implementation and I couldn`t find the class 'Primitives'. Can someone explain this part?

Problem opening UI saved images
by Sven Van Caekenberghe June 7, 2017

June 7, 2017

This has been reported before I believe, but there is something weird when saving images on the command line. On macOS 10.12.5 $ curl get.pharo.org/60+vm | bash ... $ ./pharo Pharo.image printVersion [version] 6.0 #60499 $ ./pharo Pharo.image save one $ ./pharo one.image printVersion [version] 6.0 #60499 $ ./pharo one.image eval '42 factorial' 1405006117752879898543142606244511569936384000000000 $ ./pharo-ui one.image Does not open the UI, no window, hangs, no error, nothing. Since the image itself still works, it must be a UI thing. Sven

Highlighting with pillar (html)
by Alexandre Bergel June 7, 2017

June 7, 2017

Hi! I have the following script: -=-=-=-=-=-=-=-=-=-=-=-= Any objects may be provided in place of this array. For example: [[[ g := RTGrapher new. ds := RTData new. ds points: 'What a beautiful day' substrings. ds y: [ :aString | aString size ]. g add: ds. g ]]] -=-=-=-=-=-=-=-=-=-=-=-= And it produces: Any idea where there is no syntax highlighting? In some other part of the document I go get syntax highlighting. How bizarreâ¦ Alexandre

OSProcess behaves wrong on Mac OS Sierra - Pharo 6
by Cyrille Delaunay June 7, 2017

June 7, 2017

Hello, I am running a Pharo 6 image (Latest update: #60498) on a mac sierra machine (10.12.1). I loaded version 4.6.4 of OSProcess (which is the one loaded with stable version of CommandShell project). I expected these methods to tell that I am running on a "mac unix" system: OSProcess class >> isNonUnixMac OSProcess class >> isUnix OSProcess class >> isUnixMac But they all answer that i am running on a "non unix mac" system. Problem seems to come from the following check to decide if a mac platform is "unix mac" : *(self platformName = 'Mac OS') and: [numericOsVersion >= 1000]* In my case, numericOsVersion is '10.12.1' asInteger, which gives 10 => "non unix" -- Cyrille Delaunay
