discoverability: (was: how to install all of ZincHTTPComponents?)
by Martin BÃ¤hr Jan. 31, 2015

(new thread because this is not a reply to sven, but a general observation for pharo devs) Excerpts from Sven Van Caekenberghe's message of 2015-01-30 21:19:01 +0100: > Are you sure you understand how Metacello configurations and groups works ? > You are misinterpreting what you see. how am i supposed to interpret the fact that nothing happens? > Please read the class comment of ConfigurationOfZincHTTPComponents. > You have to load (at least) the 'REST' group for what you want. and i am supposed to discover this how? two feature requests to help new pharo users: show comments by default. add support for groups in the configuration browser so they can be selected and loaded right there. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

how to install all of ZincHTTPComponents?
by Martin BÃ¤hr Jan. 30, 2015

Jan. 30, 2015

hi, in pharo3 when trying to install ZincHTTPComponents only a few additional classes seem to get installed, not the whole set packages defined in the configuration. in pharo4 (40467) it's even worse. ZincHTTPComponents is already in the image, and installing it does nothing, removing and reinstalling it likewise. how do i force a reload/installation of all the packages listed in the ZincHTTPComponents configuration? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

Implementing text navigation shortcuts
by Laura Risani Jan. 30, 2015

Jan. 30, 2015

Hi all, I like to implement a keyboard shortcut for, while editing any text, move the text pointer to the next position after $: . Seems that the base of all text editing is the class #TextMorphForEditView. I see there there is an instance variable for the text. My problem is i can not find a method that tells/sets the current position in the text of the text pointer. I've tried going through the list of methods of #TextMorphForEditView and its superclasses. Also through the one of senders of #arrowRight trying to find the instantiation of #KMKeyCombination needed to implement the existing shortcut "ctrl + right arrow" which jumps to the next position after an space, but i found nothing. Best, Laura

HTTP Token Based authentication server?
by Esteban A. Maringolo Jan. 30, 2015

Jan. 30, 2015

Is it there any implementation for token based authentication over HTTP? I know there is a OAuth client, but do we have an OAuth server? I'm migrating the authentication of our mobile apps from standard HTTP digest (user/pass base64 encoded) to token based auth, and could find very useful to have something already done to use or to build on top of. Regards! Esteban A. Maringolo

Why single inheritance?
by Laura Risani Jan. 30, 2015

Jan. 30, 2015

Hi all, What is the explanation why Smalltalk designers preferred single inheritance+traits to multiple inheritance? Why is the former better than the latter? Do traits let you share state also or only behavior? Best, Laura

Fwd: Additional easy persistence: try DebrisDB for Fuel-backed Glorp interface
by Cameron Sanders Jan. 29, 2015

Jan. 29, 2015

Along the lines of *easy model persistence while writing application code that will scale*, I strongly encourage people to *try the DebrisDB package*. Scalability (beyond what Pharo can hold in memory -- note that one boost your heap size first) can be achieved by several means: 1) deploy on Gemstone, or 2) deploy with Glorp-SQL, or ... ?) use some of these other Glorp-interface options. These solutions can co-exist. See http://smalltalkhub.com/#!/~Debris/DebrisDB MCHttpRepository location: 'http://smalltalkhub.com/mc/Debris/DebrisDB/main' user: '' password: '' *By default, out of the box, the persistence is backed by Fuel files on Pharo. See the test case.* This has only been tested in Pharo3. The demo with only about 10 lines of specialization code (as a demonstration of how to control your storage, etc.) will provide you with a Glorp interface to store data in Fuel format files. Set-up couldn't be simpler, given that the Fuel package is pre-loaded in recent images. We have not published our Gemstone compatibility source yet because I was hoping we could clean it up a bit first. But if people are unwilling to try this package until the Gemstone support is present, we can fast-track that -- but please let me know if this is an immediate requirement, otherwise, it won't happen for nearly two months. *If you have questions or problems, please let me know.* There are many improvements we can make to this package, and I would encourage others, over time, to create more variants of the DataStore that are backed by non-SQL DBs, such as Mongo, or to add the methods to persist the DataStore in Mongo, for example. Cheers, Cam

dirty packages
by Torsten Bergmann Jan. 29, 2015

Jan. 29, 2015

Because "MyPackage" and "MyPackage-Ext" fall into the same class categories. The name "MyPackage" is part of the string "MyPackage-Ext". Packages and class categories are mixed to provide Pharo packages and with this you are also still able to use old code or import code from other Smalltalks. use: "MyPackage-Core" and "MyPackage-Ext" or "MyPackage-Core" and "MyPackage-Ext-Core" and you wont have this problem. If you follow a proper naming scheme (like Seaside and mainly also Pharo) you wont get this problem. Bye T.
