Re: [Pharo-users] what is wrong here. Tests are green but the outcome with real code is much to high

by Richard O'Keefe

Not an answer to your specific question, but your #move... methods look very odd. I think you meant something like moveUpAFloor floor := floor + 1. moveDownAFloat floor := floor - 1. hasReachedBasement ^floor = -1 AH! Now I see it. You are reporting the LAST time that the lift reached the basement, but you were suppose to report the FIRST time. You want reachedBasement: input input withIndexDo: [:element :index | element = $( ifTrue: [self moveUpAFloor]. element = $) ifTrue: [self moveDownAFloor]. self hasReachedBasement ifTrue: [^index]]. "HERE" ^0 Or using a standard linear-search method, reachedBasement: input |floor| floor := 0. "ground" ^input findFirst: [:each | each = $( ifTrue: [floor := floor + 1]. "up" each = $) ifTrue: [floor := floor - 1]. "down" floor = -1 "basement"] On Tue, 18 Dec 2018 at 09:49, Roelof Wobben <r.wobben(a)home.nl> wrote: > hello > > I have this code > > hasReachedBasement: aFloor > "comment stating purpose of message" > > ^ aFloor = -1 > > initialize > "comment stating purpose of message" > > super initialize. > position := 1. > floor := 0 > > moveFloorDown: aFloor > "comment stating purpose of message" > > ^ floor := aFloor - 1 > > moveFloorUp: aFloor > "comment stating purpose of message" > > ^ floor := aFloor + 1 > > reachedBasement: input2 > input2 > withIndexDo: [ :element :index | > element = $( > ifTrue: [ self moveFloorUp: floor ] > ifFalse: [ self moveFloorDown: floor ]. > (self hasReachedBasement: floor) > ifTrue: [ position := index ] ]. > position ifNotNil: [ ^ position ] > > This works very fine with test input given by the challenge > but as soon as I do it with this : > https://gist.github.com/RoelofWobben/3be69976a6dd3531f01558b0ac563556 > > I see as answer : 6111 where I expect to see 1797 > > Anyone who can see what I did wrong ? > > Roelof > > >

what is wrong here. Tests are green but the outcome with real code is much to high

by Roelof Wobben

hello I have this code hasReachedBasement: aFloor Â Â Â "comment stating purpose of message" Â Â Â ^ aFloor = -1 initialize Â Â Â "comment stating purpose of message" Â Â Â super initialize. Â Â Â position := 1. Â Â Â floor := 0 moveFloorDown: aFloor Â Â Â "comment stating purpose of message" Â Â Â ^ floor := aFloor - 1 moveFloorUp: aFloor Â Â Â "comment stating purpose of message" Â Â Â ^ floor := aFloor + 1 reachedBasement: input2 Â Â Â input2 Â Â Â Â Â Â withIndexDo: [ :element :index | Â Â Â Â Â Â Â Â Â element = $( Â Â Â Â Â Â Â Â Â Â Â Â ifTrue: [ self moveFloorUp: floor ] Â Â Â Â Â Â Â Â Â Â Â Â ifFalse: [ self moveFloorDown: floor ]. Â Â Â Â Â Â Â Â Â (self hasReachedBasement: floor) Â Â Â Â Â Â Â Â Â Â Â Â ifTrue: [ position := index ] ]. Â Â Â position ifNotNil: [ ^ position ] This works very fine with test input given by the challenge but as soon as I do it with this : https://gist.github.com/RoelofWobben/3be69976a6dd3531f01558b0ac563556 I see as answer : 6111 where I expect to see 1797 Anyone who can see what I did wrong ?

Re: [Pharo-users] NeoCSV

Thanks, Sven! I'm trying to load NeoCSV in Pharo 5.0 from GitHub, but I get Could not resolve: BaselineOfNeoCSV [BaselineOfNeoCSV] in C:\users â¦ However, it loaded nicely in Pharo 6.1 32-bit. Both are on the same location (branch) on the disk. Is there any suggestion what to do (how to debug the situation) if one gets this kind of messages? Another misterious one is "there was an error â¦ process was cancelled" or similar, when loading with Project Catalog. Pharo is a great tool and I decided to learn it and possibly contribute, however making a stable image with the necessary tools can get quite time consuming. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Anybody knows what happened to http://planet.smalltalk.org ? I find it quite handy to catch up with multiple blog posts / feeds.
