Re: [Pharo-users] can I write this without the three if then;s
It would be an overkill to do it for this particular case, but Smalltalk makes it possible to implement a case-like construction: [ expression ] when: [ :value | condition1 ] do: [-0do :value | ... ]; when: [ :value | condition2 ] do: [ :value | ... ]; otherwiseDo: [ :value | ... ]; evaluate I am sure, something like this has been implemented already somewhere (maybe in Squeak?). Still not sure it is practical as compared to simple if-s, and for sure not widely used :) ...On the other hand, sometimes the case-like construction can be considered a more intension-revealing style. пт, 27 дек. 2019 г., 22:18 Roelof Wobben via Pharo-users < pharo-users@lists.pharo.org>: > Hello, > > Im trying to solve a challenge from exercism where I have to calculate > the points somehow gets on a very simple darts board. > > I solved it like this : > > > scoreX: anInteger y: anInteger2 > | distance | > distance := (anInteger squared + anInteger2 squared) sqrt. > distance > 10 > ifTrue: [ ^ 0 ]. > distance > 5 > ifTrue: [ ^ 1 ]. > distance > 1 > ifTrue: [ ^ 5 ]. > ^ 10 > > > but now I use three if then and I think it's ugly code. > > Is there a way I can make it more the smalltalk way ? > > > Regards, > > Roelof > >

Hi Pablo, welcome and great tool.

[Pharo-users] how to change data on real data but not on test data
--- Begin Message --- I have this code so solve a challenge of Advent Of Code : process: anArray | op | ram := (anArray splitOn: ',') collect: [ :ea | ea asInteger ]. in := ReadStream on: ram. [ (op := in next) = 99 ] whileFalse: [ self processOpcode: op ]. ^ self at: 0 that works fine for the given tests but on the real data I have to change 2 numbers so I can do : process: anArray | op | ram := (anArray splitOn: ',') collect: [ :ea | ea asInteger ]. self put: 2 at: 3. in := ReadStream on: ram. [ (op := in next) = 99 ] whileFalse: [ self processOpcode: op ]. ^ self at: 0 but that breaks all the tests is there a way I can make it work for the tests and for the real data without breaking anything ? so to be clear. In the test are data given which not has to be changed. As soon as you have to solve the real problem , some data needs to be changed. Roelof --- End Message ---

It's difficult to give good design advice with such a partial picture of the domain, but two straightforward solutions might be: 1. self isDeploymentMode ifTrue: [ "change data" ] 2. or, self sanitizationStrategy: (NoSanitization | ProductionSanitization) - Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
Re: [Pharo-users] how to change data on real data but not on test data
--- Begin Message --- Oke Maybe it is better to give the whole challenge On the way to your gravity assist around the Moon, your ship computer beeps angrily about a "1202 program alarm". On the radio, an Elf is already explaining how to handle the situation: "Don't worry, that's perfectly norma--" The ship computer bursts into flames. You notify the Elves that the computer's magic smoke seems to have escaped. "That computer ran Intcode programs like the gravity assist program it was working on; surely there are enough spare parts up there to build a new Intcode computer!" An Intcode program is a list of integers separated by commas (like 1,0,0,3,99). To run one, start by looking at the first integer (called position 0). Here, you will find an opcode - either 1, 2, or 99. The opcode indicates what to do; for example, 99 means that the program is finished and should immediately halt. Encountering an unknown opcode means something went wrong. Opcode 1 adds together numbers read from two positions and stores the result in a third position. The three integers immediately after the opcode tell you these three positions - the first two indicate the positions from which you should read the input values, and the third indicates the position at which the output should be stored. For example, if your Intcode computer encounters 1,10,20,30, it should read the values at positions 10 and 20, add those values, and then overwrite the value at position 30 with their sum. Opcode 2 works exactly like opcode 1, except it multiplies the two inputs instead of adding them. Again, the three integers after the opcode indicate where the inputs and outputs are, not their values. Once you're done processing an opcode, move to the next one by stepping forward 4 positions. For example, suppose you have the following program: 1,9,10,3,2,3,11,0,99,30,40,50 For the purposes of illustration, here is the same program split into multiple lines: 1,9,10,3, 2,3,11,0, 99, 30,40,50 The first four integers, 1,9,10,3, are at positions 0, 1, 2, and 3. Together, they represent the first opcode (1, addition), the positions of the two inputs (9 and 10), and the position of the output (3). To handle this opcode, you first need to get the values at the input positions: position 9 contains 30, and position 10 contains 40. Add these numbers together to get 70. Then, store this value at the output position; here, the output position (3) is at position 3, so it overwrites itself. Afterward, the program looks like this: 1,9,10,70, 2,3,11,0, 99, 30,40,50 Step forward 4 positions to reach the next opcode, 2. This opcode works just like the previous, but it multiplies instead of adding. The inputs are at positions 3 and 11; these positions contain 70 and 50 respectively. Multiplying these produces 3500; this is stored at position 0: 3500,9,10,70, 2,3,11,0, 99, 30,40,50 Stepping forward 4 more positions arrives at opcode 99, halting the program. Here are the initial and final states of a few more small programs: 1,0,0,0,99 becomes 2,0,0,0,99 (1 + 1 = 2). 2,3,0,3,99 becomes 2,3,0,6,99 (3 * 2 = 6). 2,4,4,5,99,0 becomes 2,4,4,5,99,9801 (99 * 99 = 9801). 1,1,1,4,99,5,6,0,99 becomes 30,1,1,4,2,5,6,0,99. Once you have a working computer, the first step is to restore the gravity assist program (your puzzle input) to the "1202 program alarm" state it had just before the last computer caught fire. To do this, before running the program, replace position 1 with the value 12 and replace position 2 with the value 2. What value is left at position 0 after the program halts? so as you can see in the tests there are no data changed so my code works fine and all the tests are green but when you want to work with the real data the say that you have to replace two values. So my question is how to make that part work without breaking the tests. Roelof Op 28-12-2019 om 21:46 schreef Sean P. DeNigris: Pharo Smalltalk Users mailing list wrote so to be clear.
