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

Hi, Hmm, I think I do not see it :). Letâs take it slowly. From what I see, the behavior is the same since at least Pharo 3. Here is a script that seems to reproduce your situation: Object subclass: #AAA instanceVariableNames: 'name' classVariableNames: '' package: 'AAA'. #AAA asClass compile: 'printOn: aStream aStream << name'. #AAA asClass compile: 'name: aString name := aString'. #AAA asClass new name: 'comics' In Pharo 6, we have in a Playground: In Pharo 3, we have this in a Workspace: Calling Print It on an object produces a string out of the contents of the stream, and displaying it shows the contents of the stream (so, no quotes). Calling Print It on a string produces a string of the string, and displaying it shows the quotes of the first string. You can see this in the String tab of the inspector: Does this make sense? I think this is not inconsistent, but maybe there is a better way. In any case, the behavior seems to exist since a long time.

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

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 <stepharong(a)free.fr> 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. > > âcomicsâ -> print-it -> âcomics' > > <Mail Attachment.png> > > What am I missing? > > Cheers, > Doru > > >> On Feb 18, 2017, at 6:26 PM, stepharong <stepharong(a)free.fr> 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.

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'.

confused about printString and printIt

by stepharong

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. Insert the description of the result of evaluation after the selection and then make this description the new text selection." | printString | self evaluateSelectionAndDo: [ :result | printString := [ result printString ] on: Error do: [ '<error in printString: try ''Inspect it'' to debug>' ]. self afterSelectionInsertAndSelect: printString ] -- Using Opera's mail client: http://www.opera.com/mail/

Re: [Pharo-dev] FileTree

Hi Guile, Le 18/02/2017 Ã 13:20, Guillermo Polito a Ã©crit : > We could try that... The thing is that it contains definitions of a > Smalltalk kernel, so there are alternative Boolean classes, String > classes, and so on... We would like to avoid conflicts in the image. the API of FileTree is tied to the Monticello model of smalltalk code (and the api of Monticello repositories). The MC model of code is of interest to you because it is completely decoupled from the code running in the image. It is just a bunch of objects, instances of MCMethodDefinition, MCClass... etc... regrouped in a MCVersion. What is saved, loaded and manipulated by a FileTree repository is that structure. The use is fairly clean: save a version (or a set of versions... with gitfiletree only) along with the dependencies; iterate over the contents of the MCVersion and write files / create directories. Reading with FileTree is the same process: read the directories / files and recreate the MCVersion. Now, reimplementing this gives you two strategies: look into MCFileTreeStCypressWriter to see the core methods (the ones writing the files out of the MCVersion items, such as #writeClassDefinition:to:). This is not much code, but it seems more complex than it is really because there is a lot of delegation going on and the upper Monticello repository and writer classes are not abstract enough for FileTree.

We could try that... The thing is that it contains definitions of a Smalltalk kernel, so there are alternative Boolean classes, String classes, and so on...
