--- Begin Message --- Thanks, But it looks to me I still need the ifTrue because the between gives also a true or false. Roelof Op 27-12-2019 om 20:38 schreef tbrunz: You might try Magnitude >> between: min and: max -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.htm

Re: [Pharo-users] can I write this without the three if then;s

Hi First, I think your code is readable and easy to understand. I think the problem does not lend itself too much towards having “an object oriented solution”, as such. If you are looking for a one-liner using smalltalk libraries, you could do: ({10 -> 0. 5 -> 1. 1 -> 5. 0 -> 10} detect: [ :dist

--- Begin Message --- Hello Kasper Thanks for the feedback. I also like readable and  easy to understand code but I get the feeling that it;s good practice to use as minimal as possible if then's So I wonder if and how I can achieve that here.

Re: [Pharo-users] can I write this without the three if then;s

I would probably set up an array of associations whose keys are the boundary limits and whose values are the target values (ordered, in this example, from outer to inner). Then loop over the array's associations using inject:into:, testing for the point where (each < key), at which point you ret

Re: [Pharo-users] can I write this without the three if then;s

Doing it the way I describe above eliminates repetitive if-then statements ('switch' or 'case' statements in other languages, which make for a maintenance mess), automatically extends for additional rings, doesn't embed "magic numbers" for defined rings within the decision logic, and takes advantag

Re: [Pharo-users] can I write this without the three if then;s

You could also accomplish this with a simple 'do:' construct by creating the associations with the the ring limits & points "staggered" (by one level), so that when (each < key) you can return the 'current' association value... Which, now that I'm looking closely at your solution, Kasper, seems to

Since you're splitting a String, why not use a Regex to do this? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] can I write this without the three if then;s

Myself, I see only one issue in your code, and that is the pointless use of sqrt. scoreX: anInteger y: anInteger2 | radiusSquared | radiusSquared := anInteger squared + anInteger2 squared. radiusSquared > 100 ifTrue: [ ^ 0 ]. radiusSquared > 25 ifTrue: [ ^ 1 ]. r

You know, this is an area where style opinions differ a lot. What the message is suggesting you try is aString splitOn: [:each | ' -_' includes: each] That's all. No need for anything more complicated. But there is a trade-off. Clarity vs efficiency. You should make your code clear and correct

[Pharo-users] Hi Community

Hi everyone, my name's Pablo and I'm from Argentina. I'm taking my first steps in Pharo and created this tool (https://github.com/pablo1n7/Smallbook) to share with my colleagues and show them the power of Pharo. It's a simple library to create slide presentations and show them in a web browser.
