Re: [Pharo-users] Hot to retrieve values from Nested Dictionaries

If you are using NeoJSON you might want to take a look at the NeoJSONObject class. It's basically a Dictionary with "JavaScript" behavior. I.e. you can simply use messages to access keys and non existing keys return nil. Your example can thus be written as: val := dict1 key1 key2 key3. When us

Maybe we could introduce `@` message, so one can chain them and then even execute keyword without parenthesis Dictionary>>@ aKey ^ at: aKey dict @ 'key1' @ 'key2' @ 'key3' dict @ 'key1' @ 'key2' @ 'key3' select: [ :each | ... ] I'm always adding this when hacking around, maybe we could

Re: [Pharo-users] Hot to retrieve values from Nested Dictionaries

For these use cases it would be nice to have some sort of syntax sugar as with the cascade operator, but with a chaining operator instead. The chaining operator would send the message to the result of the previous statement instead of the original receiver as in the semicolon cascade operator (;).

Hi Alistair. Do you know that you are able to count any message send? (not only external). For this you need prevent meta recursion. Now inside message processing you do: aMessage sendTo: anObject which produces another intercepting message #perform:withArguments which repeats original message s
