Re: [Pharo-dev] confused about printString and printIt

[stepharong]

Hi doru

may be I do not see the obvious.
I defined a class

Object subclass: #MFElement
    instanceVariableNames: 'name parent'
    classVariableNames: ''
    package: 'MyFS2'

printOn: aStream
    parent isNil ifFalse: [ parent printOn: aStream ].
    aStream << name

name: aString
     name := aString


MFDirectory new name: 'comics'.


And when I do


(MFDirectory new name: 'comics')
comics/


(MFDirectory new name: 'comics') printString

'comics/'

Hi Stef,

I think I do not understand the issue.

Here is the screenshot of a Playground.

‘comics’ -> print-it -> ‘comics'



What am I missing?

Cheers,
Doru

Hi guys



And I do not understand the behavior of print-it

(MFDirectory new name: 'comics')
comics/


(MFDirectory new name: 'comics') printString

I'm working on an introduction chapter for my future book and I do not like the behavior I see in latest pharo 60.

'comics/'

Why print it does not produce ''?
