Hello,

I have to make a word count from a sentence so I did this :

countWordsSentence: aString     | splitted result |     splitted := aString splitOn: [ :each | ', ' includes: each ].     result := splitted         inject: Bag new         into: [ :wordBag :word |             wordBag                 add: word;                 yourself ].     ^ result valuesAndCounts

but now I see that the Bag is containing nills. I tried to delete them by doing this :   cleaned := result reject: [:each | each isNil]

but to my surprise the nills are still there, Why is that happening and what is the best way to delete them ?

Roelof,

I guess your are taking about what you see in the inspector... There is nothing to worry about.

Try inspecting wordBag asOrderedCollection and see if there are still nils. Or ask the Bad for occurencesOf: nil.

It is completely normal to see nils in an Inspector on a Set or Bag. Has to do with internals of Set's and Bag's. These nils are there, but not for you ;-)

Hi Roelof,

one thing I sometimes dislike about the way you try to find your way is that you almost never answer to anything people ask or tell you. This is not only not helpful, but also off-putting.

I was asking you a simple question: did you get any errors due to nils or are you just wondering why nils show up in an Inspector? And I wrote that if this is only about what you see in an inspector, you shouldn't worry.

Your answer: "I will try to make the tests green".

Red/Green/Yellow tests have never been a topic in this thread. You had just written "I see nils". Where? When? What did you expect?

Sorry, but that kind of answer just gives me the feeling you are either not listening or not giving sh*t abot my time. If you aren't listening, please tell me and if possible give me a reason for it. I will stop answering your questions and not bother you any more. If you find my answer isn't helpful, please ask back or tell me what I am misunderstanding. Maybe we just need to talk about a tiny detail that hasn't been mentioned before. Or tell me what else is wrong with my advice in your opinion.

Don't get me wrong: I also tend to ask way too unspecific questions. And I often really feel bad about it. Most of the time it is just my helplessness that keeps me from mentioning all the details that are required to give a decent answer. Asking intelligent questions is hard, at least in my opinion. It is especially hard if the room around you is filled with way more question marks than orientation points. But that shouldn't keep you from helping people who try to help you and ask back for more details. Sometimes people ask in order to get info on what you really are asking about. It may or may not help in finding out if I (or anybody else) can help. And it may help the right answer to your question.
