hi everyone. I am facing a problem. I cloned a repo. of package. After that i tried saving and opening that package using Monticello Browser. But whenever i try save & open that package in pharo, all class and extension files are getting deleted and pharo is showing nothing in that package. Any suggestion??? One more thing i want to ask, i.e, how to make .extension files (like .class files) in pharo. Any resources on this topic? Thanks Rohit

pillar source import
by Peter UhnÃ¡k March 14, 2015

March 14, 2015

Hi, is it currently possible to import file contents into pillar? For example I have a script stored in my-script.st and I would like to do something like [[[source=my-script.st ]]] or {import 'my-another-pillar-file.pillar'} or something like that. I can overcome this with some bash preprocessing, but is there some syntax, or plan for it directly in Pillar? Thanks, Peter

For an upcoming project I'm thinking about what technology to use. I think it will be seaside or amber+tide. For the latter I would like to have some experience reports. Is anyone of you using tide and what is your experience with it? thanks, Norbert

Group external method under custom tag
by Laura Risani March 13, 2015

March 13, 2015

Hi all, I have a 'package1' that defines methods in other packages (in a method group with its name). If while at a class browser i select 'package1' these methods are shown but not if i select any of the package's tags. Is it possible to show them under a custom package1's tag? (instead of defining an additional package named 'package1-customTag') Love, Laura

Searching package for comment content
by sergio_101 March 13, 2015

March 13, 2015

Hi, all. Does anyone have any ideas on this? I would like to be able to do a quick text search in all classes and methods in a package for text. for instance, when i see an opportunity for a refactor, i put a comment something like: "TODO: break this method apart here" and move on.. it would be great if i could quickly find all methods in my package that contain the text "TODO" in a comment somewhere. Thanks!

The -vm-display-null parameter is specific to Ian Piumarta's unix VM. It is part of the loadable VM module system that he made for sound and displays. You will find this in the various VMs that run on top of Ian platform code. The Windows VMs originate from Andreas Raab's code base, which has different VM command line parameters. For common things like starting a headless VM, it would be a good idea to make the command line parameters consistent across VMs. Maybe that could be done most easily in the start scripts, as opposed to the VM executables.

Esteban, i am trying to deploy a Seaside app in Windows. I want pharo running headless and i will want to implement it as Windows Service. But does not matter. Trying start pharo4 last image last vm ( https://ci.inria.fr/pharo/) in headless . pharo -vm-display-null -vm-sound-null imagefile.image --no-quit. It does not work. Abort pharo -vm-sound-null imagefile .image --no-quit. I works but with gui. I hope it will help you to understand the situation. Ing.

[OT] DB Open Data-Train Challenge in Germany
by Torsten Bergmann March 13, 2015

March 13, 2015

Similar to the Dataton in Paris (http://lists.pharo.org/pipermail/pharo-users_lists.pharo.org/2015-March/017…) with data from Africa to visualize possible with Roassal there is in germany next friday (20.3.2015) a day in Frankfurt organized by german railway, also with open data (timetables, train data, ...): https://www.eventbrite.com/e/db-open-data-train-challenge-tickets-160262449… So if one might be interested to visit the event. BTW: German railway is using Smalltalk applications a lot to do all their timetable planning and train simulations (see http://www.uic.org/html/it/e-business_2005/docs/woelfle.pdf for some screenshots) Maybe this is a good chance to demo Pharo or use Roassal to visualize data.

configuration browser descriptions
by Torsten Bergmann March 13, 2015

March 13, 2015

Sebastian wrote: >One should discuss if it might be useful and easy to implement to have a configuration browser >that includes descriptions for the offered configurations. I guess I'm knowledgable enough to answer this: a) it is useful b) if it is easy depends on where you get the description info from c) Do not dicusss, stop lamenting and help coding :) When I wrote the config browser there was no central way to find out which packages/configs are working for which Pharo version. The easiest thing that could possibly work was to create a MetaRepoForPharoXXX repo for each version XXX of Pharo and copy the working configs into it. The tool just queries the list of available file names and displays them. For the initial step this was enough and still good enough that the tool opens quick enough. If you would LOAD ALL the configs in such a meta repo BEFORE OPENING into the Pharo image to extract more informations (like descriptions or dependencies) the config browser would be unusable due to bad performance of such operations. This could be solved by caching, but so far there was no time. Additionally as it makes sense to store such descriptions with the config Stef implemented Catalog. Some ConfigurationOfYYY classes have such meta data for Catalog and the project currently produces an HTML report: https://ci.inria.fr/pharo-contribution/job/PharoProjectCatalog/HTML_Report/ One must know about this. Not ideal - but a step forward to at least make it visible somehow. Several options: ================ 1. Implement a solution to load all the config in the meta repo into the image, extract the data the first time and write this info to a cache. Update the cache on request. It MUST be cached, otherwise it will burn CPU cycles. Although this cache can be shared between Pharo image with the same version I think this is not ideal. 2. Using Stefs "Catalog" project one could (beside the HTML report) provide something that is easy to parse from the tool so we can load the contents of the displayed list from the web quickly When the CI runs often it should be up to date always - but we must make sure such a job is never broken. Would be a better option - but also needs someone to do that. 3. In the long term: Implement a better online mechanism to register Pharo related stuff. Some kind of PharoStore where you can register and share Packages but also other things like tutorials, articles, video, wallpapers, ... Then the client can query for this info (maybe using Spotter) and just load. Feel free to shape/code on improving this. There is something in the pipe for 3. from my side already, but only slowly progressing maybe too much work for one person. If you want to help and know Pharo and Seaside very well then contact me offline.
