A Morphic ScrumBoard, part 4: Other planning boards
by Stephan Eggermont July 27, 2015

July 27, 2015

Pharo is an excellent environment for building interactive applications. In part 4 of this series, I take a look at a planning tool for time slot based planning. This is not so common in software development, but is used a lot in simple and complicated contexts. In the example, there are 4 rooms that can be scheduled between 8:00 and 18:00 at a granularity of 5 minutes. An element panel is added as a new kind of drag panel containing prototypes of the tasks that can be planned. Here the prototypes are no longer the squares from the earlier drag panels, their height depends on the amount of time they take. When a task prototype is dragged to the plan board, the responsible party can be selected using spotter. https://vimeo.com/134547026 Stephan

Hi, is there somewhere documentation for Catalog Browser? Specifically what everything it offers for configurations... I've seen on class side methods #catalogKeywords, #catalogDescription but since I've haven't found docs (maybe Updated Pharo Book can have?) I don't know what else it offers. Thanks, Peter

Personal wiki / information manager
by Bystroushaak July 26, 2015

July 26, 2015

Hello. Is there any software projects/libraries for personal wiki (something like ZIM or CherryTree or Orgmode for writing texts/notes) and personal information managing in Pharo? I think that Pharo would be great for this kind of software, because it would provide rich scripting options. Also the idea of representing informations as objects is really great. For example; now I keep list of books I read in DSV file. With this SW, I could have a list of objects representing the books, which could be sorted or rendered to lower level protocols, like DSV/XML/whatever.

Ephemeric Cloud - new platform to publish Pharo web applications
by mikefilonov July 25, 2015

July 25, 2015

Dear Pharo users, I'm so excited to introduce you a project I'm currently working on which is called "Ephemeric cloud". It is a very simple and fast way to publish your Images to the web. Basically to publish a Smalltalk Image you just need to call a usual HTTP POST request to Pharocloud Ephemeric API and you'll get a hostname in response. Check those small video examples below. 2 minutes each (and most of the time is uploading time of my not-so-fast home internet :) Publish with curl: http://www.youtube.com/watch?v=9dKBCpj96cU Publish with Drag&Drop: http://www.youtube.com/watch?v=NuGTenCIwik The main idea of the project is to put as many images as possible and as simple as possible. And I'm so confident in efficiency of this solution that I included a free plan for you guys:) Hooray to Pharo Free hosting! :) (scared smile) I see Ephemeric cloud as a corner stone of all Pharo web development. For instance, I can imagine some kind of "Publish" button on Marina project site, clicking on which a user will spawn a new instance in the cloud and will be able to test it immediately. Another good use case is running unit-tests by publishing an Image and running some API calls on it by script. Or you can have an A-B publish scheme when a part of users are sent to a new version for a test and the rest to a stable one. By the way, ephemerics are a great case for Pharo Remote Debug project;) My intentions are to get to the point when Ephemeric cloud subscription is a must-have tool for a Pharo developer! :) You may check some project details here: https://www.pharocloud.com/kb/tutorial/ephemerics-introduction All questions are so-very welcomed. If anyone is interested in participation in cloud beta-testing please contact me at support(a)pharocloud.com and I'll extend your subscription plan. Cheers, Mike Pharocloud Team -- View this message in context: http://forum.world.st/Ephemeric-Cloud-new-platform-to-publish-Pharo-web-app… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

saving text files from inspector
by Peter UhnÃ¡k July 24, 2015

July 24, 2015

Hi, it seems that I cannot save text files from inspector, only if they are smalltalk (.st) files, in which case a different text editor tab (Script, instead of Contents) is opened up. Is this an oversight or an intention? Thanks, Peter

Class side vs instance side
by Peter Uhnak July 24, 2015

July 24, 2015

Hi, I am trying to figure out where to best place some mapping/data/stable methods. For example imagine method ~~~~~~~~~~~~~~~~~~~~~ MyRectangle>>oppositeSides ^ { #top -> #bottom. #bottom -> #top. #topLeft -> #bottomRight .... } asDictionary ~~~~~~~~~~~~~~~~~~~~ And then the class might have some other related methods such as ~~~~~~~~~~~ MyRectangle>>oppositeSideFor: aSide ^ self oppositeSides at: aSide ~~~~~~~~~~~~ So it's a method returning a mapping between opposite sides/corners and thus is really not going to change. Now I could place this in instance-side and create a new instance every time I wanted to use it (which doesn't seem practical), or I could put it in class-side. The problem I have with class-side is that naming is more like going through minefield (more than once I corrupted my image by naming a method or variable something I shouldn't have), and for whatever reason it feels like either metaprogramming or procedural programmming... That class side methods are pretty much global functions/variables... and short of constructors I am avoiding static methods even in other languages... but maybe using it is ok. Or maybe have it object an use singleton? The only oop-like approach I see would be to extend symbols (#top oppositeSide), or have separate objects for sides, but that seems like overkill. MySide subclass: #Top Top>>oppositeSide ^ Bottom new Are there any best practices regarding this? This is also true for actual data stored in methods/attributes (such as icons). P.s.: For english natives... Should the second method be ned "oppositeSideOf:" or "oppositeSideFor:"? Any ideas/pointers appreciated, Peter

gitfiletree metadata
by Peter UhnÃ¡k July 24, 2015

July 24, 2015

Hi, it seems that I managed to completely fuck up my gitfiletree metadata... e.g.: Ancestors: DynaCASE-PeterUhnak.148, DynaCASE-PeterUhnak.93, DynaCASE-PeterUhnak.144, DynaCASE-PeterUhnak.146, DynaCASE-PeterUhnak.92, DynaCASE-PeterUhnak.142, DynaCASE-PeterUhnak.140, DynaCASE-PeterUhnak.138, DynaCASE-PeterUhnak.139, DynaCASE-bliznjan.127, DynaCASE-PeterUhnak.137, DynaCASE-PeterUhnak.125, DynaCASE-PeterUhnak.126, DynaCASE-bliznjan.123, DynaCASE-bliznjan.121, DynaCASE-bliznjan.120, DynaCASE-PeterUhnak.119, DynaCASE-PeterUhnak.117, DynaCASE-PeterUhnak.115, DynaCASE-bliznjan.113, DynaCASE-PeterUhnak.111, DynaCASE-PeterUhnak.110, DynaCASE-PeterUhnak.108, DynaCASE-PeterUhnak.102, DynaCASE-bliznjan.95, DynaCASE-bliznjan.98, DynaCASE-PeterUhnak.91 I am also starting to see a lot of ghost changes etc. Now, someone mentioned that it would be possible to delete all the .version and methodProperties.json and whatnot and generate it directly from git. So my question is, is this possible? If yes, how? If no, what would need to be done (implemented) to make it so? Or at least is it possible to completely regenerate all the metadata purely from git? (To clean up all the mess until.) Peter
