Sven I was thinking about the API you could you have a variant of put: onStream: that put the printed version of the argument. Because this is what I thought it was doing.

If you just put it there, all the characters will be there but the string will not be quoted, nor will embedded quotes be escaped properly. Yes I thought about it. I was thinking that we are pretty low-level for template programming. May be RBrewritter is the way to go.

Packaging question

by Stephane Ducasse

Hi I'm developing a small library named Chrysal (to be announced when ready - the successor of Cocoon) that supports configuration files (and conversion of strings into our lovely objects). The idea is that based on description objects, a class is generated statically with all the conversion logic. Now a configuration for an App is a subclass of one minimal class called ChrysalConfiguration. and this class is packaged into the ChrysalRuntime package this is the only thing needed (I could remove it by automatically recompiling even more code but looks a bit terrible at the end). Now my question. Should I propose two BaselineOfs? One for the Generator and one for the Runtime? I thought so. And generator should depend on the runtime. Stef

You're sick that is why you are not thinking clearly ;-) This has nothing to do with STON, but with Smalltalk syntax. Say you want to write out a Date creation expression, then the following (what you do) would not work: Compiler evaluate: (String streamContents: [ :out | out << 'Date fromString: '. Date today printOn: out ]). But the following does (as I did): Compiler evaluate: (String streamContents: [ :out | out << 'Date fromString: '. out print: Date today printString ]). You need to take the printed representation and turn it into a Smalltalk String literal. If you just put it there, all the characters will be there but the string will not be quoted, nor will embedded quotes be escaped properly. > Stef > > On Tue, Mar 13, 2018 at 5:13 PM, Stephane Ducasse > <stepharo.self(a)gmail.com> wrote: >> On Tue, Mar 13, 2018 at 5:12 PM, Stephane Ducasse >> <stepharo.self(a)gmail.com> wrote: >>> Tx sven got caught by a flu... freezing in my bed. >>> I will check. >>> >>> On Mon, Mar 12, 2018 at 11:01 PM, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: >>>> So I guess that you want a Smalltalk expression that, when evaluated, returns an arbitrary STON-ified object as a real object. >>>> >>>> Let's say you want to STON-ify the following object: >>>> >>>> { #firstName->'StÃ©phane'. #lastName->'Ducasse'. #note->'Look: '', that was a single quote.' } asDictionary. >>>> >>>> Note there is a single quote character inside the #note. >>>> >>>> You can do that using #print: when needed.
