Spec - vertically stacked Menu(Group)Model
by Peter UhnÃ¡k July 17, 2014

July 17, 2014

Is it possible to force MenuModel to display its groups (and group's items) vertically instead of horizontally? The use case is having button palette to click on. Both world menu and subMenu of MenuItemModel render it this way but it is all hidden in the depths of Morphic. Is there any way how to switch this behavior at Spec level? (Or should I make it from scratch?) Peter

RFB: caught MessageNotUnderstood: Float>>bitShift:
by Damien Cassou July 17, 2014

July 17, 2014

Anyone has an idea why RFB would try sending #bitShift: to a float? This crashes the 2 VNC viewer I've tried. This happens when moving a window in Pharo through the VNC client. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

How do I get a halo on a specific UI object in Pharo 3/4?
by Tim Mackinnon July 16, 2014

July 16, 2014

In older versions of Squeak pharo - I think alt-click would cycle you through halos on objects in the UI. I have noticed in Pharo 3/4 - if I ctrl+shift click I get a menu that has many options, one of which is "add halo" - but how do I control which UI element I will get a halo on? Similarly - there is "inspect" in this menu, and it does give me a list of widgets (saying deepest first) - however I can't easily see which element corresponds with what is in the list? I know the old squeak halo system wasn't favoured - but now I try and find things in Pharo 3/4 - I miss the ability to visually cycle through items to understand what I can inspect? Is there no way to do this now? It was very useful.

read an email with attachment

Hi Pablo, could you be more specific: - would you like to connect to a mail server and read the mails including the attachement (if so which protocols do you need, POP, IMAP and MAPI comes to mind) - or would you just like to extract it from a saved email file format Pharo includes support for POP3 (POP3Client and ZdcSecurePOP3Client used for sending mails). Typically it is used to send mails. Dont know if current implementation has support to retrieve mail infos as well, if not it would be good when code is extended to the according RFC. If I remember correctly there was also POP3 client to retrieve mail infos to Squeak, just google it. http://smalltalk.org/videos/video_Classes_POP3Client.html There was/is also Celeste - an email reader tool for Squeak. Dont know if code is still part of the base Squeak system. Porting may be easy (file in/file out) or hard (adoption as Pharo changed a lot after forking from Squeak). http://wiki.squeak.org/squeak/1467 Also read: http://www.codejava.net/java-ee/javamail/download-attachments-in-e-mail-mes… regarding attachements. Hope this helps T.

Should I be reporting bugs in Pharo 3.0?
by Tim Mackinnon July 16, 2014

July 16, 2014

I don't want to create lots of noise - or create unnecessary work, but if I find bugs in Pharo 3.0, should I be reporting them? Or do you want me to try and repro them in 4.0 and then report them under 4.0? For example, I have a class that was a subclass of CustomHelp that overrode the class #pages method. I then decided to use Wiki help, and so moved my class to subclass Object, but then i noticed that the #pages method (which I was about to delete) still had an override green arrow symbol. Curious - I clicked it and got a walkback (as the UI is wrong). How do I report that? Do you want me to? I do have a fobgugz account. I've also noticed another error with the locked methods pane (not sure what to call it, and also really don't fully understand how it works). However it gets corrupted with long wrapping strings in the source. Do I report that?

Advice on making a first contribution
by Tim Mackinnon July 16, 2014

July 16, 2014

Hi guys - I've decided to try and use moments of spare time to see if I can contribute in small ways (and I'm sorry I can't contribute in big ways - but maybe I will get up to that point). Anyway - I've thought it would be handy to improve the help text in Pharo - as this it where I first looked to find out a few things about the new environment, and discovered that the help doesn't really provide help on the environment. So having scouted around and looked at the help engine - it seemed like easiest way was to use the WikiHelp support, and put a pragma in a suitable place (initially I subclassed CustomHelp - but I think that is for more sophisticated uses than just documenting some basic help). Anyway - I created a package called "Pharo-Help" - and so my first question is: Are there names I should avoid, or conventions I should follow for good package names? I've then created a class "PharoEnvironmentHelp" with a class method #wikiStyleHelp (which is a convention I've seen in other places) - and it reads the class comment so it's easy to edit. However - should I use a separate class for this? It does keep it out of the way - but it ends up not being a class that does anything - so I could put this text on something else that represents "Pharo" - or is this fine? I've also given it the name "? Pharo Help" so it appears at the top of the list - my thinking being that new users would probably expect intro help at the top and the "?" does this. Finally - how do I submit it? (and I'm happy to read up on this, if there is something that has it nicely documented).

Storing block closure code
by Norbert Hartl July 16, 2014

July 16, 2014

I was looking for a solution where I can have a textual grammar for a DSL in order to specify filters on objects. I didn't really search the net because I know a cute little DSL for that already. It is called smalltalk, you might have heard of it. So what I do is putting the filter spec into the image via an http interface, materialize the filter in image and store it in a database to have them survive image restart. A filter spec could look like this [ :value | ( self sectionLabelOf: value ) = 'device' ] I want to know if there is any trouble to expect if I'm using plain block syntax for that task. As the blocks are injected using an http interface there is no environment/context problem. I would have some helper class as a facade to ease the filtering let's call it FilterHelper (would have a class side method #sectionLabelOf:) So getting the block code via HTTP I could do block := Smalltalk compiler evaluate: request contents for: FilterHelper logged: false And I would serialize it into a database as a string again doing self store: block sourceNode formattedCode Are there any possible drawbacks using it this way? thanks, Norbert

FYI - I've raised a bug that the pharo website doesn't have a video showing how to report bugs anymore. 13553 - Reporting issues video on Pharo website reports "Does not exist" Not sure if it's right to raise an issue - but thought it made sense (and given I can't watch the video... ;) Tim -- View this message in context: http://forum.world.st/I-ve-raised-a-bug-that-the-Pharo-website-has-a-missin… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
