For example, in a Workspace or any method you can execute the following.... ------ ivars := 'aaa bbb ccc'. newclass := #MyTest.

Re: [Pharo-users] Is there a way to automatically format a method during the compilation phase or immediately after?

by Paul DeBruicker

Which version of Pharo? in 1.1-1.4 open the world menu, click system, click settings, type format, click the top 5 checkboxes. Probably the same in Pharo 2 too.

Note I am actually only doing this for the first time, so I'll lay it out in detail in case I can learn from someone else poking holes in it. 1. Bring up the context menu in the browser so that it shows the <Format> menu item 2. Use Alt-Shift-Click (on Windows) to bring up halos on the <Format> menu item, so that you see it is aToggleMenuItemMorph 3. Click the green Duplicate action then put the menu item down on the background. Check that clicking that copied button will format the code in the browser 4. Bring up halos on that duplicated menu item, so that it shows as aMenuMorph (I don't know why it changed from aToggleMenuItemMorph) 5. Click the grey spanner to Debug > Inspect Morph 6. Notice that instance variable 'submorphs' is aToggleMenuItemMorph. Inspect 'submorphs' and then inspect item 1 of the Array to get an inspector on aToggleMenuItemMorph. 7. This inspector shows the following instance variables... target: anORCmdFormat selector: #perform:orSendTo: In the pane at the bottom of the inspector, execute... self selector: #xxx:yyy: and observe the instance variable change 8. Click the duplicated menuitem still sitting on the background. A debugger opens with a MNU #xxx:yyy: Observe that the following message is selected... perform: selector withArguments: arguments since in [12.] you will Step Into this point. 9. Select the second line from the top of the call stack, which is #invokeWithEvent: Observe the instance variable 'selector' shows #xxx:yyy: 10. In the bottom pane second from the left, execute... self selector: #perform:orSendTo: and observe the instance variable change 12. Click <Restart> from the debugger Step Over until you can Step Into the message you observed in [8.] After twice stepping-into, you should be in ORCmdFormat>>execute which looks like it has a few things that will be useful to you. I'll leave it there for you to continue tracing. cheers -ben

Re: [Pharo-users] Using Utility classes - follow up to How do I save contents of Workspace into a collection?

by StÃ©phane Ducasse

Frank did you see that you can create instance variable accessor using the class browser. I did not check in OmniBrower in Pharo1.4 but in Nautilus in 2.0 this is there. And it is a refactoring so it makes sure that you do not override by accident an existing method. Stef

You could call ClassX addVariablesNamed: aCollection in this case Is ClassX an example of the MyUtils class Igor mentions? I tried that option using ClassDescription but got an MNU error.. e.g. right now I use the first option in this manner: | anyVariable | anyVariable := ClassType new. anyVariable addVarsAndTheirAccessors: #('aaaa' 'bbbb' 'cccc') How would I attach the method to a utilities class and ClassDescription for that matter as it would then apply to all classes? -- Frank Church ======================= http://devblog.brahmancreations.com
