Sending notifications from Pharo to your Mobile via Pushover.net
by Sven Van Caekenberghe Jan. 30, 2018

Jan. 30, 2018

Hi, Just a little snippet I wanted to share. Pushover (https://pushover.net) is a general service that delivers notifications to iOS, Android and desktop devices via an API (and an email gateway as well). It is really easy to get started with. This is how you do it from Pharo: ZnClient new systemPolicy; url: 'https://api.pushover.net/1/messages.json'; accept: ZnMimeType applicationJson; contentReader: [ :entity | NeoJSONObject fromString: entity contents ]; contentWriter: [ :object | ZnEntity json: object asString ]; contents: (NeoJSONObject new token: 'ax4o55o6g5imb1a6st3m9x34hqu44z'; user: 'uv2fovx3f9sp3rgssrupvjgvdo8quw'; title: 'Test 3'; message: ('This is a test @ {1} by {2}.' format: { DateAndTime now. SystemVersion current })); post. It will look like this on your mobile device (just seconds later): Nothing special, but pretty handy.

by Animosity Jan. 30, 2018

Jan. 30, 2018

Hi there, I'm not able to find any setting in the Pharo IDE related to changing the mouse cursor color or size? Can this be done at all? Thanks in advance. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Regex: copy with ignoreCase
by Herbert VojÄÃk Jan. 30, 2018

Jan. 30, 2018

Hi! String >> #asRegex return an instance of RxMatcher, as I tried. Now, I would like to get an object that behaves exactly as the one I got from asRegex, just that it ignores case (regardless whether it did or didn't in the original object). I understand it is not possible to get that object with existing API, is it? Herby

Iceberg and resource files
by kmo Jan. 29, 2018

Jan. 29, 2018

I don't understand how iceberg handles resource files that you might also like to version along with the pharo code. Say I have an CSV file and a text file that my pharo application uses. How do I include these in the iceberg commit/push? How do I see changes made in these files from version to version? Does iceberg only handle pharo code? Generally git clients don't care about the file type - and it it is any kind of text you can see the actual differences between each commit.

Problem with Traditional and Simplified Chinese parsing in Pharo
by ClÃ©ment Bera Jan. 29, 2018

Jan. 29, 2018

Hi, I am currently parsing lua and JSON-like file in Pharo. They contain both Simplified and Traditional Chinese characters for comments and for strings displayed in the UI. Lua files are parsed correctly. However the JSON-like files aren't. In attachment I put one of the problematic file with Simplified chinese characters (I've also copied the file at the end of the mail). The problem can be shown as follow in Pharo: 'schinese.txt' asFileReference readStream contents The contents function sends a UTF8InvalidText 'Invalid utf8 input detected' error. However my text editor correctly displays the file and it is correctly parsed by the Lua runtime (The program parsed has been deployed in production for years and works fine). What can I do to parse this file correctly from Pharo ? Thanks, Below is the file content, non Chinese people may not have the font to display the characters, note that I have no idea what is written in Chinese (Please don't hold me responsible if there are offending contents): "lang" { "Language" "Schinese" "Tokens" { "text_store_cd" "è´å£³ååºçååä¼æ¯å¤©éæºå·æ°! ä¸æ¬¡å·æ°å·å´æ¶é´" "text_cannot_huidaoguoqu" "ç°å¨ä¸è½ä½¿ç¨åå°è¿å»~" "tips1" "å©ç¨é¼ æ æ»è½®å¯ä»¥è°èè§è§è·ç¦»ï¼æ¹ä¾¿ä½ æ¥çåºå°å¨è²~" "tips2" "éè¿å¨é¨50å³ä»¥åä½ è¿å¯ä»¥ç»§ç»æææ´å æé¾åº¦çæ å°½è¯ç¼æ¨¡å¼ï¼" "tips3" "æ¯å¤©æ©æ¨è´å£³ååºä¼éæºå·æ°åéæºææï¼çå¿ä½ æ³è¦çååï¼" "tips4" "æè¡æ¦çå25åå¯ä»¥è·å¾çå å¥ç« ï¼è±¡å¾çä½ å¨å¡é²æ¸¸æä¸çåè¶æç»©ï¼" "tips5" "æ¯10æ³¢æäººä¼æä¸ä¸ªBOSSå³å¡ï¼å®æ¯æ®éæäººæ´é¾å»æ~" "tips6" "é£è¡çæäººä¸ä¼è¢«ç³å¤´é»æ¡ï¼æä»¥ä¸è½å©ç¨è¿·å®«æ¥å¢é¿æªç©ççº¿è·¯~" "tips7" "å¼å±çæ¶åç¹å»å·¦ä¸æ¹çè±ééæ©å¾æ å¯ä»¥æ¥çå¹¶éæ©ä½ æ¥æçè±éï¼" "tips8" "éèº«çæäººå¿é¡»éè¿èç½ç³»åå¡çç§æåç¯æè½è¢«åç°ï¼" "tips9" "ç¹å»å³ä¾§çåæå¬å¼æé®å¯ä»¥æå¼åæé¢æ¿ï¼äºè§£é«çº§å¡çåæä»¥åå½åéä»¶ç¶æ~" "tips10" "éè¯·å¥½åä¸èµ·æ¸¸æï¼å¯ä»¥äºç¸åä½å±åå¯¹æå¼ºå¤§çæäººï¼" "tips11" "ç³æ¿ä¼å¯¹è¸©ä¸å»çæäººäº§çææï¼æä»¥æå¥½æ¾ç½®å¨æäººå¿ç»çè·¯çº¿ä¸~" "tips12" "ä¸ºè±éè´ä¹°ç¾ä¸½çç¹æï¼å½ä½ å¯ä»¥ä¸åååæçæ¶åææéä»¶é½ä¼æç¹ææç¤ºï¼" "tips13" "æ¯ååä¼¤å®³æé«çå¡å°ä¼è·å¾æå¤10å±çMVPåç¯ï¼å¢å ç©çåéæ³è¾åºï¼" "tips14" "æ¯ä¸ªæçæåä¸å¤©æ¯èµå£ç»ç®æ¥ï¼å°ä¼æ ¹æ®ä½ è¿èµå£çæåé¢åä¸°åçè´å£³å¥å±ï¼" "tips15" "å¦æä¸ç¥éææ ·é è¿·å®«ï¼ä½ å¯ä»¥ç¹å»å³ä¾§çè¿·å®«æåæé®æ¥çæèåäº«æ¨èçè¿·å®«~" } } -- ClÃ©ment BÃ©ra Pharo consortium engineer https://clementbera.wordpress.com/ BÃ¢timent B 40, avenue Halley 59650 Villeneuve d'Ascq

[JOB][PhD] Infrastructure and Language Kernels for IoT Systems
by Marcus Denker Jan. 29, 2018

Jan. 29, 2018

[JOB][PhD] Infrastructure and Language Kernels for IoT Systems The RMOD team of INRIA Lille and the CAR theme of IMT Lille Douai have an open position for a PhD student on Infrastructure and language kernels for IoT Systems. Description ========== Over the last years, the RMOD team of INRIA Lille and the CAR theme of IMT Lille Douai have been working together on creating tiny language core. For example, Guillermo Polito demonstrated in his PhD a fully reflective kernel that fits into 80 kb of memory and that it is possible to have hyper specialized kernels down to 11 kb. We have also worked on remote debugging (PhD of N. Papoulias) and dynamic code updates (PhD of P. Tesone) of such kernels. All of these works are prototyped in Pharo. More recently, RMOD have been working on advanced probes mechanisms (M. Denker) and a solid remote debugging infrastructure (D. Kudriashov). The goal of this PhD is to revisit the architecture around such mini-kernels for building IoT applications. The plan is to: ============= â¢ improve the tools to edit, compile, debug, deploy and update such kernels on IoT devices. Learn how to debug remotely and dynamically update such IoT systems using the TelePharo/PharoThings environment. This task will be in cooperation with M. Denker and D. Kudriashov on remote debugging for IoT and G. Polito for the kernel edition and tooling. â¢ define some language extensions to manage groups of IoT devices to program them at once. Managing hundreds or even thousands of IoT devices is a challenging task. We want to explore different solutions to help deploying and updating groups of IoT devices using some registration mechanism in a cloud server or some groups/roles based approaches for example. Note that ZweiDenker GmbH http://zweidenker.de/en/ is interested in collaboration on the IoT cloud management infrastructure â¢ expressing the architecture of IoT applications. We would like to explore also how to express IoT architectures and what are the abstractions that should be offered to developers such as expressing event-driven architectures with declarative ECA (Event-Conditions-Actions) rules. But we will study a couple of typical IoT applications. â¢ dynamically update an IoT application. An IoT application needs to adapt itself because unreachable or faulty devices or the diminution of available bandwith. We would like that the whole application can reconfigure itself in such situations as Guillaume Grondin proposes it in its PhD. â¢ explore Lightweight Virtual Machines. Virtual machines in the IoT context are very powerful for incremental deployment or dynamic updates. In this task, we would like to investigate what is the minimal memory consumption that we can reach for a VM usable for IoT. Application ========= To apply, please send us : â¢ a CV, â¢ a copy of your Master diploma â¢ a copy of your Master thesis â¢ 2 (two) reference letters, with the contact details of the referents â¢ links to videos of demos of your experiments and/or simulations The application materials should be sent by email to Prof. S. Ducasse stephane.ducasse(a)inria.fr. Email subject must start with : [PhD-RMoD-CAR-2018]. Bibliography ========= â¢ Guillermo Polito, Stephane Ducasse, N Bouraqadi, L Fabresse, M Mattone.

How to specify generic (non-github) git dependency?
by Herbert VojÄÃk Jan. 28, 2018

Jan. 28, 2018

Hi, I know I can do, for example, [..snip..] package: 'Foo' with: [ spec requires: #('Mocketry') ]; baseline: 'Mocketry' with: [ spec repository: 'github://dionisiydk/Mocketry:v4.0.x' ]; [..snip..] but when I want to add dependency to a repo which is not on github nor on bitbucket, how do I specify (https or scp) git depedency in generic way? Thanks, Herby

Voyage and Instance Mode
by Dominique Dartois Jan. 27, 2018

Jan. 27, 2018

Hello all. I'am learning to use Voyage by trying the examples in the Voyage doc (in the Enterprise Pharo book). I read "By default, Voyage works in instance mode". If I run the example in instance mode, I get an error via the debugger. |repo anAssociation| repo := VOMemoryRepository new. anAssociation := #answer -> 42. anAssociation save: repo. ==> "Instance of Association did not understand #save:" What am I doing wrong? -- Dominique
