How to contribute to PharoLauncher?

by Tim Mackinnon

Hi - Iâve added a few interesting features to PharoLauncher, but Iâm not sure what the steps are for contributing to a SmalltalkHub project? My proposed changes are as follows: - Change default image template name to include the parent folder name (e.g. Pharo 4.0 (beta)-540123 vs. 450123) - Add a new image command âImage Summaryâ that shows you the date of the last image modification as well as the contents of âdescription.txtâ - as I canât always remember why I have some old images kicking around (this change is quite basic - I couldnât see how best to create a nice popup window so I reused the deny: one with a new title. I did think possibly a hover over balloon or having something like the comments panel in Pharo - but its a modal dialog for now) - I changed the Run icon to a play button (as the process icon used - seemed a bit obscure) Tim

Re: [Pharo-users] Roassal2 RTDraggable grid and synchronized movement

AST source interval isn't changed

by Mark Rizun

Hello, I have MyTextModel class - a subclass of TextModel, it holds an ast of it's text. When I replace node of the ast using replaceWith: ast is changed, then I say text: ast formattedCode, so the text is changed too. But! when I inspect new ast(after replacing some node), I see that source interval isn't changed. Why? If I say bestNodeFor: someInterval, it doesn't give me the right node, because sourceInterval of ast wasn't changed, and I don't know why. Hope you will help me out:) Best, Mark -- View this message in context: http://forum.world.st/AST-source-interval-isn-t-changed-tp4772779.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

A slice is basically just a set of mcz files So there is no problem at all to use slices for your personal projects :) Ben On 10 Aug 2014, at 23:24, Tim Mackinnon <tim(a)testit.works> wrote: > I will make a not to try Versioneer (although the image I am using is the one PharoLauncher is built in, which is 3.0). > > Anyway - I did try making a slice with bug number 0, and my own description, and it let me create one and save it in my own repository.

How do I trace through implementors in Pharo?

by Tim Mackinnon

As I relearn/learn how to use Pharo, Iâm struck by some of the excellent changes and confounded by some of the simple things that boggle me. So, I wanted to follow a path through some message sends - the use of #alert:title: in UIManager specifically. So I browser UIManager, find the method (its subclassResponsiblity) - so I find other implementers (cmd+b, cmd+m) - (Iâm really liking that there are more keystrokes in newer Pharoâs but not liking that the same operations donât have the same bindings in different windows - e.g. in the debugger - its not this!!) Anyway - this gives me an implementors window on TEasilyThemed - great! In the source, there is another msg send - ^self alert:title:configure: So I want to follow its implementers - I hi light the source and cmd+b,cmd+m does nothing? hmmm - right click there and the context menu doesnât have an obvious way - until I spot (Extended Searchâ¦) [which by the way should be shown as a submenu - like it does in the SystemBrowser). In this menu there is âimplementers of itâ - however this does nothing? (this is in both Pharo 3.0 and Pharo 4.0) So how do you trace through method calls? Am I doing something wrong - or has this been broken for a long time? Tim
