Intended behaviour of flatten and flatCollect:
by Konrad Hinsen April 13, 2022

April 13, 2022

Hi everyone, I am getting surprising results trying to flatten nested arrays. So I read the docstrings. And now I understand even less how flatten and flatCollect are supposed to work. flatten says: "Recursively collect each non-collection element of the receiver and its descendant collections. Please note, this implementation assumes that strings are to be treated as objects rather than as collection." That suggests that #(1 2 3) flatten should yield #(1 2 3). But it raises an exception, trying to send do: to an integer. A quick look at the code shows that flatten is just flatCollect: [ :each | each ]. flatCollect: says: "Evaluate aBlock for each of the receiver's elements and answer the list of all resulting values flatten one level. Assumes that aBlock returns some kind of collection for each element. Equivalent to the lisp's mapcan" "Flatten one level" is different from flatten's "recursively". The assumption that aBlock returns a collection is also incompatible with what flatten is supposed to do (and explains my exception). I don't find the reference to a Lisp function very helpful. Assuming "Lisp" means "Common Lisp", this confirms the docstring of flatCollect:, this confirms the assumption of aBlock returning a collection, and that only one level of nesting is flattened. Since flatCollect does what it says, the problem seems to be in flatten. Either its docstring or its implementation are wrong. Or is it me misunderstanding something? Cheers, Konrad

WebDav and CalDav in Pharo ?
by CÃ©drick BÃ©ler April 13, 2022

April 13, 2022

Hi all, I do some experiments with iCal. For now I serve a full calendar over HTTP. Not bad, but it is read only. Iâd like to try CalDAV. I was looking for it, and also webDAV. Gofer it smalltalkhubUser: 'UdoSchneider' project: 'FileSystemNetwork'; configuration; load. #ConfigurationOfFileSystemNetwork asClass project stableVersion load: 'Webdav' Iâve found the project of Udo, but it doesnât load on P8. I think this is due to the stream refactoring. Right now the image hung. Iâll try maybe to load it manually. But I was wondering oof there were other alternatives ? TIA, CÃ©drick

ReStore and storing mixed dictionaries
by Offray Vladimir Luna CÃ¡rdenas April 13, 2022

April 13, 2022

Hi all, First of all, despite of being on a non-directly related matter with my question, congrats of Pharo 10. We (as now we have 2 active Smalltalkers in my country... Yay!) are creating a civic tech project with Pharo/Lepiter and we would like to store some Tweet metadata coming from Nitter[1]. As we're dealing with the differences between the official Twitter API and the unofficial Nitter one, we put the metadata we need in a dictionary that has several kinds of objects, from ordered collections to other dictionaries. [1] https://nitter.net/about Currently if we serialize a Tweet object in STON, we get this: Tweet { #created : 'Tue, 05 Apr 2022 12:37:56 GMT', #text : ' [ANN] Pharo 10 Released: pharo.org/news/pharo10-releaâ¦ <https://pharo.org/news/pharo10-released> \n', #id : '1511322244353597443', #user : NitterUser { #userName : 'pharoproject', #profileImageUrl : URL [ 'http://nitter.42l.fr/pic/pbs.twimg.com/profile_images/541743734/icone-pharo…' ] }, #metadata : { 'queries' : OrderedCollection [ { 'date' : DateAndTime [ '2022-04-05T13:36:58.546011-05:00' ], 'parameters' : 'https://nitter.42l.fr/pharoproject' } ], 'timelines' : { 'pharoproject' : '1511048498703126529' } } } As you can see, the metadata slot contains a dictionary with mixed classes of objects. But I read in the ReStore manual[2] (pg 14): """ Like other collections, the class of elements for both key and value can be any other persistent class, and will be the same for all elements of that collection (except in the case of inheritance). """ So, is ReStore unable to store metadata dictionaries like the one described in the previous STON code? if this is possible, how can I define it in the Tweet class>>reStoreDefinition? For the moment, I'm going to create a explicit "timelines" slot to store what was being stored at the #timelines key of the metadata dictionary. But, as metadata increases, instead of moving variables previously inside of a dictionary as explicit slots of an object, I think that having a explicit way of storing dictionaries with different kinds of objects, in contrast with only uniform ones, would be needed (but I don't know if this is in the design scope of ReStore). BTW, Lepiter has allow us to build a pretty fluent interface to browser Twitter/Nitter profiles and messages. Here it is how such UI looks for browsing last @pharoproject tweets: https://i.imgur.com/bxFze1g.png Any help on how to use ReStore in storing mixed dictionaries is appreciated. Thanks, Offray

[ANN] Pharo 10 released!
by Esteban Lorenzano April 8, 2022

April 8, 2022

Dear Pharo users and dynamic language lovers: We have released Pharo version 10 (https://pharo.org/) ! Pharo is a pure object-oriented programming language and a powerful environment, focused on simplicity and immediate feedback. Pharo 10 was a short iteration where we focused mainly on stability and enhancement of the environment : Massive system cleanup gained speed removed dead code removed old/deprecated frameworks (Glamour, GTTools, Spec1) All Remaining tools written using the deprecated frameworks have been rewritten: Dependency Analyser, Critique Browser, and many other small utilities. Modularisation has made a leap, creating correct baselines (project descriptions) for many internal systems, making possible the work and deployment of minimal images. Removing support for the old Bytecode sets and embedded blocks simplified the compiler and language core. As a result, our image size has been reduced by 10% (from 66MB to 58MB) The VM has also improved in several areas: better async I/O support, socket handling, FFI ABI, Even being a short iteration, we have closed a massive amount of issues: around 600 issues and 700 pull requests. A more extended changelog can be found at https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo100Chang…. While the technical improvements are significant, still the most impressive fact is that the new code that got in the main Pharo 10 image was contributed by more than 80 people. Pharo is more than code. It is an exciting project involving a great community. We thank all the contributors to this release: Aaron Bieber, Ackerley Tng, Alban Benmouffek, Alejandra Cossio, Aless Hosry, Alexandre Bergel, Aliaksei Syrel, Alistair Grant, Arturo Zambrano, Asbathou Biyalou-Sama, Axel Marlard, Bastien Degardins, Ben Coman, Bernardo Contreras, Bernhard Pieber, Carlo Teixeira, Carlos Lopez, Carolina Hernandez, Christophe Demarey, Clotilde Toullec, Connor Skennerton, Cyril Ferlicot, Dave Mason, David Wickes, Denis Kudriashov, Eric Gade, Erik Stel, Esteban Lorenzano, Evelyn Cusi Lopez, Ezequiel R.

Re: WebDav and CalDav in Pharo ?
by Jonathan van Alteren April 4, 2022

Hi CÃ¨drick, Udo, Any update on using WebDAV/CalDAV in Pharo? We need to work with it as well. We have created a GitHub repo from the SmalltalkHub project here:Â https://github.com/objectguild/FileSystemNetwork All unit tests are green using a test server URL created usingÂ https://www.webdavserver.com. However, there seem to be some issues handling the actual file contents. Is there anybody with experience of the Pharo 8 implementation of FileSystem etc. who wants to assist? (FYI, we cannot work in Pharo 9 (or 10) yet because of technical contraints.) Best, Jonathan van Alteren Guild Member | Object Guild B.V.
