Me too:
'Could not load ObjectLiterals-SvenVanCaekenberghe.4.mcz:
ZnHttpUnsuccessful: 404 Not Found'
however, the monticello repository window shows it is there.
Nicolas, any clues what going on?

Sven,
For some reason I can't see any of the packages in your project on SmalltalkHub, but I was just curious if your work depends upon a pre-existing Smalltalk parser or not?
I assume that "the JSON issue" will come up in a month or two again, so it is worth knowing the answer ahead of time:)

| Hi,
|
| I took Igor's initial code and created a new project:
|
|       http://smalltalkhub.com/#!/~SvenVanCaekenberghe/ObjectLiterals/
|
| and I added ObjectLiteralParser to convert any Character Stream or
| String into a Smalltalk Literal Array and eventually into an Object.
|
| This proof of concept moves the ObjectLiteral format/notation away
| from the Smalltalk compiler and will help us discuss more concretely
| the actual details of the specification (which is still not 100%
| finished).
|
| I also added 12 unit tests and cleaned up the code and comments.
|
| Please have a look at the code.
|
| This is one of the tests:
|
| ObjectLiteralParserTests>>#testMixed1
|       | input output |
|       input := '
|               #(Array
|                       1
|                       foo
|                       #''foo-#bar''
|                       true
|                       false
|                       nil
|                       3.14159
|                       -100
|                       ''string''
|                       (#OrderedCollection 7 8 9)
|                       #(Set 10)
|                       (Dictionary
|                               x 1
|                               y 2) )  '.
|        output := {
|               1.
|               #foo.
|               #'foo-#bar'.
|               true.
|               false.
|               nil.
|               3.14159.
|               -100.
|               'string'.
|               OrderedCollection withAll: #(7 8 9).
|               Set with: 10.
|               Dictionary newFromPairs: #(x 1 y 2 ). }.
|       self assert: (self parserOn: input) nextObjectLiteral equals: output
|
| I like this format, its simplicity and elegance is appealing, it
| offers distinctive advantages in the Smalltalk context while its
| slight readability disadvantage is acceptable. Like any format it is
| a compromise and a tradeoff, but a rather good one.
