There is something similar in GitHub.com/ba-st/Buoy called Optional. It's not a full fledged Monad implementation but for most cases it would do.

Re: [Pharo-users] Iceberg and resource files

by Stephane Ducasse

You can version such code in your repo using git. Now Iceberg does not manage them (from what I understood). We will probably have a kind of GitRepo file Location so that you can know from where you want to load such files. (Right now pointing to "IceRepository default" should work).

Iceberg and resource files

by kmo

I don't understand how iceberg handles resource files that you might also like to version along with the pharo code. Say I have an CSV file and a text file that my pharo application uses. How do I include these in the iceberg commit/push? How do I see changes made in these files from version to version? Does iceberg only handle pharo code? Generally git clients don't care about the file type - and it it is any kind of text you can see the actual differences between each commit.

Can you do a pull request to update the book? Or do we let rot the documentation? Is the same sentence present in the Voyage booklet?

"Maybe monad is a programming pattern that allows to treat nil values that same way as non-nil values" At a minimum you can just define required methods on UndefinedObject. For example... UndefinedObject >> myThing self inform: 'Nil does my thing!!' then in Playground evaluate... nil myThing This obviously doesn't cover the "Some" part of Maybe-monad, but you didn't provide any description of what you're trying to do so I don't know how important that is to you. However, in general a better approach than adding methods to UndefinedObject if to use the Null pattern. Initialize your variables with an instance of MyDomainNull which defines the minimum required messages to avoid DNUs. Such a class might fit as the root superclass of all your domain classes. But this suggestion might be off target, since I can't grok where I'd use something like Maybe-Monad in my own programming. cheers -ben
