Re: [Pharo-users] eval from the linux commandline

by Tim Mackinnon

Eval works fine on Linux - I use it for tons of build stuff to launch an image pass a build script with AWS parameters in a constructed dictionary for example.

by Steve Quezadas

is it part of the base image? It's not listed in spotter. I also checked the packages for something beginning with Clap and it's not there either. I am also running linux, so "eval" is not an option in my commandline.

Re: [Pharo-users] how to get out of this mess

In OOP, you should not be thinking in terms of "updating a record". You should *ask* an object to update *itself*. [aStream atEnd] whileFalse: [ |fields team1 team2 outcome| fields := aStream nextLine subStrings: ';'. team1 := self teamNamed: (fields at: 1). team2 := self teamNamed: (fields at: 2). outcome := fields at: 3. outcome = 'win' ifTrue: [team1 won. team2 lost]. outcome = 'draw' ifTrue: [team1 tied. team2 tied]. outcome = 'loss' ifTrue: [team1 lost. team2 won ]]. (Extracted from a working solution.)

This is a simple programming-contest sort of exercise. You "need" only two classes. + a Team - knows its name (a String of at most 30 characters) * This should be passed when the Team is created; the rest of the program should NOT call (Team new) and should NEVER see an un#initialize-d Team instance. - knows the number of matches it has won, drawn, and lost (non-negative Integers, initially zero). - can report what it knows - can report the total match count and point score - can be told that it has won, drawn, or lost another match. + a Tournament - has a collection of Teams that it knows by name (a Dictionary) - and an sequence, initially undefined. - can read a set of match triples from a stream, forwarding the information about wins, draws, and losses to Team instances, which are created when a new name is found, - can convert the values of the teams collection to a sorted collection that is sorted by a somewhat vague order, I chose - descending on point score, then - descending on wins, then - ascending on losses, then - ascending on name. - can write the sorted teams to a stream in tabular form. ! Has a class method that does (self new) read: <<source>>; sort; write: <<destination>> Frankly, formatting the output was the hardest part.
