SIXX tab consideration

by Dario Romano Trussardi

Ciao, I use sixx environment to export - import data from Pharo - Gemstone. I think it would be interesting in the creation of sixx file, to make optional the tab indentation. On my database, the file size difference is substantial: from 3MB to 2MB. Thanks for any consideration. Dario

Re: [Pharo-users] Find/Replace class scoped

by Vitor Medina Cruz

Oh! Thanks!! So the correct message to send is execute. The transform actually do nothing, it only stores the changes that are executed by the RBRefactoryChangeManager.

browsing references to elements of Undeclared?

by Craig Latta

Hi all-- In various Smalltalks, I'm used to being able to open an inspector on the Undeclared dictionary, then selecting an element and browsing references to it. I don't seem to see that functionality in Pharo 8. Is there an equivalent? thanks!

Re: [Pharo-users] Find/Replace class scoped

by Thierry Goubier

Hi Vitor, I got it to work (integrated it as a command into my IDE, and wrote the auto-detect part for the permutation), with the following algorithm (I've removed the IDE-specific part): | aClass aSel newSel ast aMap | aClass := RefactoringReformatExample. aSel := #with:doThis: newSel := UIManager default request: 'Enter the new selector and arguments' initialAnswer: (aClass >> aSel) ast selectorAndArgumentNames. (newSel isNil or: [ newSel isEmpty ]) ifTrue: [ self inform: 'Cancelled'. ^ self ]. ast := aClass compiler parse: newSel. aMap := ast argumentNames collect: [ :e | (aClass >> aSel) ast argumentNames indexOf: e ifAbsent: [ self error: 'Incorrect argument name: ' , e. ^ self ] ]. (RBRenameMethodRefactoring renameMethod: aSelector in: aClass to: ast selector permutation: aMap) execute If your initial method is 'with: arg1 doThis: arg2', you write the new selector as 'doThis: arg2 with: arg1' and it will pick up the permutation map for you.

Re: [Pharo-users] Name of coding pattern

by Richard O'Keefe

In my library it would be strm tag: 'h1'; do: aBlockWhichWritesTheTitle; end. because one so very often needs to add attributes and/or a namespace. #tag:do: is related to the C++ "Resource Allocation is Initialisation" pattern, where the point is to automatically clean up. In RAII, the clean up is to release a lock or free a resource. In this case, it is to write an end-tag. In a similar way, it is related to the Common Lisp with... pattern, where (with-open-file (variable filespec option...) body...) ensures that the file is closed, to unwind-protect, and of course to the #critical: method on Semaphores, Mutexes, &c. I don't know if there is an official name other than RAII; I've always thought of it as "automatic cleanup". The difference between this and #ensure: or try-finally or unwind-protect is that in those you have to say what the clean-up action is while in this it is implicit.

Re: [Pharo-users] Find/Replace class scoped

by Vitor Medina Cruz

Will wait then. I tried to use the RB classes but with no success. There are few docs and test code are hard to understand (still not sure if I should use transform ou primitiveExecute). I did this: (RBRenameMethodRefactoring new renameMethod: #with:doThis: in: RefactoringReformatExample to: #withh:doThis: permutation: #(1 2)) primitiveExecute and (RBRenameMethodRefactoring new renameMethod: #with:doThis: in: RefactoringReformatExample to: #withh:doThis: permutation: #(1 2)) tranform but nothing happens... It is really odd, I expected an error at least. I am assuming permutation means the change of params order.
