Hi Sven - is there no convenience shortcut we can use in our code to make this
less wordy when we are specifying it?
E.g. the following is very convenient to write - but doesn’t work (as you have
$‘ and not $“ )
ex := { 'track'-> 'pharo'.
'language' -> 'smalltalk'.
'exercises' ->
{'slug' -> 'hello'.
'id' -> 55.
'topics' -> #('a' 'b' 'c') }
}.
String streamContents: [ :stream |
(STONWriter on: (stream)) prettyPrint: true; writeList: ex ].
I had thought maybe NeoJSON might help and put:
String streamContents: [ :stream |
(NeoJSONWriter on: (stream)) prettyPrint: true;
"mapInstVarsFor: Association;"
nextPut: ex ].
But I get the error about missing an association mapping. If I uncomment that
bit - I get things like: { "value" : “pharo" },
So is there a way I can write a simple mapper for Association that will write
out the key in a string and the value in a string?
I’m quite suprised we can’t easily write out fragments of Json in our code in a
light weight way? Or do I need to make a proper Config object and then teach it
how to map properly such that rather than fiddling with our { x->y } dictionary
sugar I do something like:
Config new at: ‘id’ is: 123; at: ‘name’ is: ‘Tim’; at: ‘exercises’ is: #(1 2
3).
And I guess at:is: can do the Association asDictionary thing?
But I thought Neo might give me something like that, as it must be terribly
common?
