Re: [Pharo-users] Extract-method refactoring erratic behavior in Pharo 8

by Tim Mackinnon

Well said. Yes - we should work on our refactoring tools a lot more. As the inventors of refactoring and the tools that back it, weâve got to a place where we are a bit poor in this area - itâs not fluid and easy like it should be. Although - hats off to the automatic rewrite tools for migration - that is very neat. But letâs rally around making the basic refactorings enjoyable and easy again.

Re: [Pharo-users] Working directory and image directory

by Russ Whaley

I find the same anomalies in V9 for MacOS for workingDirectory pointing to root. I had to create a configuration system so I could effectively manage locations instead of using workingDirectory references. Other anomalies... when attempting to type in a (super) class in class creation - each keystroke launches debugger... same when setting up iceberg/github - typing in a package/folder name launches debugger with each keystroke... annoying, but I can get through it. Oh, this also seems to happen whenever I'm typing 'thisContext'. This all seems related to the type-ahead facility. Also a few observable issues with transmitTo: / sorting with Spec2 in V9... looks like when a column sorting issue was fixed it blew up transmitTo: ... -- sort - now sorts the pane but doesn't appropriately convey through the transmitTo: to the next pane - sometimes crashes, sometimes just doesn't display correct data... unusable, had to put this project on hold. I've asked here before how to submit a bug report - but didn't get a response (my posts are probably too benign for the experts, lol). If you know how to submit a bug report, I'd appreciate a (very) small primer or point me to a link. Thanks!

Extract-method refactoring erratic behavior in Pharo 8

by Esteban Maringolo

Hi, I get, more often than not, a message indicating an "invalid source to extract", commonly with the "End of statement list encountered" explanation. In comparison, I can extract the same code in Pharo 4. Is there a reason why the "Extract method" refactoring is not working in Pharo 8 as it was in that or any other version? Thanks! Esteban A. Maringolo

If you're using Pharo Launcher, you can update your VM from the "VMs" dialog. And from PL you can download new images; I think it fetches the latest, updated image version when you do. -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

I was wondering... Is there an easy way to update my Pharo 9.0 Development version with updated versions? I presume Pharo 9.0 is constantly changing. And how frequently are there updated versions?

Re: [Pharo-users] Want to create a text Field using SPEC2 to get Value from User

by kmo

You need to do two things. Firstly, you need to create a label. Secondly, you need to add it to the layout. The first bit is easy. You create the label in the initializePresenters method just like you did the button and the text field. There's a method that creates a label. If you open a system browser (CTRL+O+B) on SpPresenter and have look at the methods you will see which one to use. It's obvious, really. To lay out the field and the label the way you want you need to add the label to the layout in the class method defaultSpec. However, the existing SpBoxLayout there can only lay out the controls either vertically or horizontally. So you can have the controls going from top to bottom or left to right but that's all. If you want to have the label and the field on one line and the button underneath you will have to replace the SpBoxLayout with a SpGridLayout. This lays out things in a grid of columns and rows. Then you add the controls like this: add: #myTextField at: 2@1 This places the control in column 2 of row 1. You don't have to define or size the columns - the SpGridLayout does it all for you. Hope this helps. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

If this works... myButton whenActivatedDo: [LibC system: 'a.bat 10']. and this doesn't... myButton whenActivatedDo: [LibC system: 'a.bat', myTextField asString]. and you can't see why, then you likely have an assumption about what you think is happening, that is blinding you what is actually happening, which you need to expose :) i.e. you need to know *exactly* what string is being passed in the #system: call. One way to do that is to replace "LibC system:" with "Transcript:show:" in your code. cheers -ben. myButton whenActivatedDo: [ Transcript show: myTextField text]

Working directory and image directory

by Davide Varvello

Hi Guys, As I already described here: http://forum.world.st/Fuel-FLSerializer-tests-are-not-working-pharo-8-td512… there is something weird on Pharo 8 (on Mac) because I'm running an image that is in the same directory of the Pharo.app but "FileLocator workingDirectory" give me the root directory. I expected the same directory where there is Pharo.app Cheers Davide -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
