[Pharo-users] Some issues with Pharo and Ubuntu

[Vitor Medina Cruz]

Hello,

I am trying Pharo with Docker and I will leave here some issues I had since
I am unsure where I should report them. The command I am running is:

Metacello new baseline: 'Employees';
 repository: 'tonel:///home/employeesSource/pharo/';
 ignoreImage;
 onConflict: [ :ex | ex useIncoming ];
 onWarning: [ :ex | Transcript crShow: ex ];
 silently;
 load: #(core).

To load the latest Seaside in Pharo 7 I use the develop branch:

Metacello new
 baseline:'Seaside3';
 repository: 'github://SeasideSt/Seaside:develop/repository';
 load.

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

Re: [Pharo-users] NeoCSV

[eftomi]

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 …

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 …
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.

Re: [Pharo-users] NeoCSV

[Sven Van Caekenberghe]

Loading a Tonel project on GitHub using a BaselineOf only works in Pharo 6.1 
and higher, AFAIU.

Pharo 5 is already pretty old ...

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

[Roelof Wobben]

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 ?

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

[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"]

[Pharo-users] Teapot installation

[horrido]

/Something/ has recently changed. The following now incurs an error:

Gofer it
   smalltalkhubUser: 'zeroflag' project: 'Teapot';
   configuration;
   loadStable.

The error is: "Could not resolve: ConfigurationOfNeoJSON in
/home/richard/blah blah blah"

What's going on???

Re: [Pharo-users] Teapot installation

[Renaud de Villemeur]

Hi

Teapot has been moved from smalltalkhub to github. The new location is
https://github.com/zeroflag/Teapot

You can have a look at the doc on how to install it, either standalone or
as a dependency.
https://github.com/zeroflag/Teapot/blob/master/docs/Installation.md
