Hi Usman, The method at:ifAbsentPut: does not interpret the argument. Just put "self myAuthor" instead of #myAuthor, it should work.

The following expression: self privateState attributeAt: #authors ifAbsentPut: #myAuthors returns me a symbol #myAuthors instead of evaluating the method myAuthors. myAuthors is a method that I introduce in FamixType as an extension and it returns a Bag. Why is this expression returning a symbol instead of evaluating #myAuthors as a block? thanx Usman P.S: The package can be downloaded here: http://www.squeaksource.com/FamixAuthors _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev --- Jannik Laval _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev

because the block is only executed if the first arg is absent. this comes from dictionary my dict at: kjhkjh ifAbsentPut: [] stef On Nov 6, 2011, at 3:37 PM, Andre Hora wrote: wrote: MooseEntityState of FamixType. myAuthors. it returns a Bag. #myAuthors as a block? http://www.squeaksource.com/FamixAuthors _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev

btw... just for info... famixmethod already has author information embedded in timestamp attribute ...

In moose ? because in pharo this is like that and the changes I added where just to make sure that all the clients do not have to deal with timestamp stupid parsing.

Hi Stef, It is not so simple :) Take this example from Moose: === LANNode methodDictionary collect:[:e | e timeStamp ifNotEmpty: [:s | s subStrings first ]] === LANNode has no author, so if you take the first substring you will have the date of creation. I have not a good solution, but for my scripts, I test the first character of the substring: if it is a letter, this is an author, else, there is no author. === ((myString subStrings) first at:1) isLetter === Cheers, On Nov 6, 2011, at 21:48 , Stéphane Ducasse wrote: --- Jannik Laval
