[ANN] Pharo Catalog web page updated
by Esteban Lorenzano Oct. 11, 2015

Oct. 11, 2015

Hi, I spend some time today adding some functionality top the Pharo Catalog web page. Is still far from *good* but I think now is a lot better: http://catalog.pharo.org Enjoy, Esteban ps: as a âhistoryâ note, Pharo Catalog page was never intended to last too much, it was going to be replaced for a complete web-page, and it still will be, but since is not ready and I donât know when it will be, I think is better to enhance the current one :)

ifNotEmpty(Do):
by Peter UhnÃ¡k Oct. 11, 2015

Oct. 11, 2015

Collection>>ifNotEmpty: comment says "If the block has an argument, eval with the receiver as its argument, but it might be better to use ifNotEmptyDo: to make the code easier to understand" yet when I do that, Code Critic complains: ifNotEmptyDo: should not be used as ifNotEmpty: works for blocks with arguments, too. 1) who is right? what should I use? 2) shouldn't one be deprecated then? (or maybe one of them is to be compatible with other smalltalks?) Thanks, Peter

Better Code Completion
by Peter UhnÃ¡k Oct. 10, 2015

Oct. 10, 2015

This is both rant and list of questions/notes/observations... ...but first of all: do Smalltalkers not like code completion? Because the one in Pharo is really poor and not only that nobody is doing anything about it, *but also nobody is complaining*; this leads me to believe that you either a) don't have the manpower (this is true pretty much always, so no complaints here) b) don't care about this that much (since you lived without it for 45 years) at least from the lack of complaining to me it seems that b) is more likely scenario... But since I do use it, I get annoyed by it quite a bit, especially since I regularly work in IDEs where this thousand times better. Now I would like to get things moving a bit (or bury it and forget it), so I have couple of questions and would appreciate if someone could provide some feedback. 1. Methods of core/top classes should be deprioritized Since Object has almost 500 methods whatever I will start typing Object/TClass/TBehavior/... will have a list of answers... so let's start typing... Very often I have to type almost full word to see what I want. Shouldn't the completion follow the inheritance chain? So first it shows me matches from the class itself (especially since it actually knows the type) and only after then it's parents and so on? 3. Or maybe even show the (closest) class that implements it. So the last two items would have somewhere (beginning or the end) written '(Object)' and the first two '(yourself)' (or the class's name). 2. The window has fixed size, so if I have longer method (as in picture above) I don't see it all. 3. Is middle-of-the word really that often used? See moseIntere<sti>ngEntity above. It feels to me that it just creates a lot of false positives (I have this problem also with inspector btw, so I often have to prefix it with >># or if I see it already lot of <arrow down>, which is annoying) 4. We write tests, however how often have you manually created an instance of a test class by hand? I think they should be either filtered or deprioritized as they create visual clutter. This is probably also true for many other classes such as ConfigurationOf/Manifest/... Nobody instantiates them by hand. 5. How often do you send #abs to a dictionary? Maybe also deprioritize extension methods? 6. If I have already written part of the selector it's impossible to "continue" and add an extra parameter. This is because it doesn't know if I am code completing for dict, or #key. Maybe different shortcuts? <tab> to code complete on #key, and <shift+tab> to code complete on the previous one... or maybe cycle through them because this can be nested (the currently code completed item would have to be highlighted somehow). 7. So if I don't want to see the above I have to type it manually; which is fine for #at:put: but not for longer words.. (just to find out ten seconds later that I have a stupid typo there). 8. The code completion doesn't show parameter names. This is very helpful because it often reveals what it actually accepts. Now I have to actually look into the code of the method. Now we can hardly compete with typed languages, but I think there's a lot lot room for improvement. For comparison from other languages/IDE's. PhpStorm/PHP (notice how it shows the whole method if it's longer than the window and doesn't it just clip)â NetBeans/C++ In the picture above it âstill provides hinting when typing the parameter. TypeScript playground â(similar to NetBeans) Also they have in their online playground better and nicer code completion than we have in actual env (http://www.typescriptlang.org/Playground ) So if you have any thoughts/feedback/whatnot on this matter, I would greatly appreciate it.

Deleting methods

Hi! When I select methods, I often get a MessageNotUnderstood: isDefault is sent to nil within: RBUnpackagedCodeRule>>isUnpackaged: Am I the only one to experience this?

by FÃ¡bio Petrillo Oct. 9, 2015

Oct. 9, 2015

Dear Pharo Manager, I am a really newby in Pharo and I was trying to copy-and-paste a code in a Playground, but it didn't work. The original copy was in Google Chrome web page and I used Ubuntu OS. I solved my problem when I pasted to GEdit editor and I copied another time in GEdit. Finally, I pasted in Pharo Playground. My objective is just report this issue. Thank you so much! Best regards, Fabio Petrillo

MNU: RubPluggableTextMorph>>appendEntry
by Alexandre Bergel Oct. 9, 2015

Oct. 9, 2015

Hi! A new Pharo user bumps into a nasty bug. No idea why it appears time to time. The method ThreadSafeTranscript>>stepGlobal does a "self changed: #appendEntry.â This apparently update by RubPluggableTextMorph by calling "RubPluggableTextMorph >>update: #appendEntryâ. All this ultimately sends #appendEntry to RubPluggableTextMorph, which is not understood. What is the solution for this? https://pharo.fogbugz.com/f/cases/16749/MNU-RubPluggableTextMorph-appendEnt… Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

How do I run Pharo on Debian?
by justonium Oct. 8, 2015

Oct. 8, 2015

I've downloaded Pharo 4.0. When I open the folder that was downloaded (pharo4.0), I see a file called pharo. I think I'm supposed to run this, but I don't know how. When I right click it, there is no run option. What should I do? -- View this message in context: http://forum.world.st/How-do-I-run-Pharo-on-Debian-tp4854180.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Text Field With Entry Completion Via Tab
by Sean P. DeNigris Oct. 8, 2015

Oct. 8, 2015

With all the new tools - Spec, Brick, Tx, etc - what is the easiest way to do this in Pharo 4.0? I don't have a preference for the tool as long is it works in Morphic. My naive attempt failed: applicants := PaPerson list collect: #name. entryCompletion := EntryCompletion new dataSourceBlock: [ :currText | applicants ]; filterBlock: [ :currApplicant :currText | currApplicant asUppercase includesSubstring: currText asString asUppercase ]. TextInputFieldModel new acceptOnCR: false; entryCompletion: entryCompletion; openWithSpec. The completion menu appears, but is seems you can only accept the selected completion via the mouse - yuck! Thanks. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Text-Field-With-Entry-Completion-Via-Tab-tp4853993.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi all, I'm looking for a dbus client for Pharo, I saw there is a project on SH (http://smalltalkhub.com/#!/~DamienCassou/DBus) but the package that should contains pure-smalltalk implementation is empty. Is there something working to send messages via dbus? Regards, Julien

Pharo for the Software Architect: a Wardley Value Stream Map
by Stephan Eggermont Oct. 7, 2015

Oct. 7, 2015

Pharo provides an excellent platform for the Software Architect. It is easy to quickly create interactive tools. The Grafeo graph drawing library makes it easy to create a Wardley Value Stream Mapping tool: this prototype is just 6 classes and 40 methods. https://vimeo.com/141653455 Wardley Maps (http://blog.gardeviance.org) help create strategic situational awareness and support better decision making. Architects need moldable tools that require little effort to keep up to date and support collecting and distributing information in various formats. We can improve on PowerPoint and Excel. The prototype needs Grafeo and WardleyMap from smalltalkhub StephanEggermont/Documentation Stephan
