Pillar html export clickable headers
by Peter UhnÃ¡k March 19, 2015

March 19, 2015

Hi, I have a small feature request for Pillar to be considered - clickable/linkable headers in html output. Often I want to link someone to specific chapter of a document. For example in Sphinx documentation http://sphinx-doc.org/tutorial.html#autodoc each section has an id and when you hover the header with mouse there is a Â¶ symbol I can click on. Peter

Aconcagua: Common Measurement Systems
by Sean P. DeNigris March 19, 2015

March 19, 2015

Is there a repository for e.g. monetary, weight, distance implementations using Aconcagua? Or do users typically implement Dollar, Ounce, Millimeter, etc. from scratch for each project? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Aconcagua-Common-Measurement-Systems-tp4813202.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Also there may be some issues with NB: harder to understand than FFI, not complete for ARM, ... Also for Apple devices it is not able to generate/perform machine code in memory. But when you go native you usually have to take care of the underlying system anyway. But if I understood correctly all this new improvements/movements away from NB will be at the cost of performance: FFI will slower than NB. Or did I misunderstood? The only issues I had with NB so far ist that it initially takes some effort to know the details. But it worked great once one get used to it and I like that Pharo gets fast with it... Why not complete 64 bit, AsmJIT/NB for ARM beside x86 and where possible provide the NB layer? For other platforms we can fall back to FFI when needed. For sure there could be a more unified way to call. Maybe thats the goal of the unified FFI and I just do not know the details. Maybe NB is already planned as a possible backend and it is still possible to use it. Or will it be legacy afterwards? I do not care if it is called "NB" or "FFI" or other, but I would dislike if I had to give up performance or native possibilities or if we just throw away something that was developed/integrated with effort into the image initially. I guess more info or patience is required...

when iterating over a collection how to determine the current objects index
by Sanjay Minni March 19, 2015

March 19, 2015

Hi when iterating over a sequenced collection (array / ordered collection) how can I determine the current objects index value (without explicitly storing a counter or looking to match each time) Typically I need it: 1. to display a serial number when printing a report. 2. to determine if I am on the last element. 3. To highlight every n-th element. regards Sanjay ----- --- Regards, Sanjay -- View this message in context: http://forum.world.st/when-iterating-over-a-collection-how-to-determine-the… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Running startup scripts after the UI has finished
by Peter UhnÃ¡k March 18, 2015

March 18, 2015

Hi, is it possible to execute startup scripts after the UI has finished rendering / the image has loaded? I have install startup script that executes when I create the image, however since it starts executing very early the UI is frozen and I don't get any progress bar so I don't know what's happening (since I'm downloading Roassal and other libraries it can take quite a while.) Thanks, Peter

Pharo and Pi
by Torsten Bergmann March 18, 2015

March 18, 2015

Read about "piCore" this week which is a Tiny Core Linux for the Pi. As there is - a quick bootable Pharo on top of TinyLinux (Mikes "PharoNOS" project) - a Pharo that is runnable on Pi I wonder if anyone already did some experiments on booting directly into Pharo on a pi. Still a "pi newbee" I also would like to know how to get started to Pharo on Pi. Seems like the CI job is not available: https://ci.inria.fr/pharo-contribution/computer/RaspberryPi/ Where to get started with Pharo on Pi these days? Any "quick guide"? Thx T.

thanks for your answers so far >we tried to start pharo 4.0 on the Parallella board OK, but I would like to give the original PI a try. Especially because there are nice additions like the Tontec mini touch screen, etc. >The problem with Pharo4 and the VM is that there is no NativeBoost nor >OSProcess available o ARM VMs. Yes NB is x86 so far. Mhh... without OSProcess or NB one can not issue commands to the underlying system (like Tiny Linux). >you can start the image, you can save it, you can load source At least it is a start and it runs. I guess I would be able to run Teapot at least. So one can use it as a simple Pharo based web (app) serving machine. Right? Is Filesystem access working (FileBrowser)? Bye T.

[ANN] MongoTalk, MongoBrowser and Mongo Spotter support
by Torsten Bergmann March 18, 2015

March 18, 2015

Beside my new article "Building a Mongo Browser in Pharo" [1] and the new Mongo Browser tool I now added support for "Spotter browsing/navigation" using a running Mongo DB to the project. Just load "MongoTalk" from config browser in Pharo 4, run you Mongo database and then use Spotter to enter a database name. Attached is a screenshot. When Mongo is running locally you can easily use spotter now to directly browse Mongo databases, included collections and documents of a running MongoDB instance. If Mongo is not running on localhost you can also switch the default db instance: Mongo default: (Mongo host: 'myserver' port: 1234) to browse remotely. Thx T.
