Stef is right, there is something strange. Consider the following 4 expressions, each time with the result of 'Print It' inserted:
#foo->'foo'. "#foo->'foo'" (#foo->'foo') printString. "'#foo->''foo'''" 'foo'. "'foo'" 'foo' printString. "'''foo'''" In a Workspace (not Playground), the following happens: #foo->'foo'. #foo->'foo' #foo->'foo' printString. #foo->'''foo''' Which makes even less sense. > On 19 Feb 2017, at 09:06, stepharong <[email protected]> wrote: > > 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' > > <Mail Attachment.png> > > What am I missing? > > Cheers, > Doru > > >> On Feb 18, 2017, at 6:26 PM, stepharong <[email protected]> wrote: >> >> >> Hi guys >> >> I'm working on an introduction chapter for my future book and I do not like >> the behavior I see in latest pharo 60. >> >> And I do not understand the behavior of print-it >> >> (MFDirectory new name: 'comics') >> comics/ >> >> >> (MFDirectory new name: 'comics') printString >>>>> 'comics/' >> >> >> Why print it does not produce ''? >> >> >> Stef >> >> >> printIt >> "Treat the current text selection as an expression; evaluate it.
