Add experimental support for JSON value types
New types:
json
json_array
json_object
New functions:
$json.value_type(<json>)
$json.value_size(<json>)
$json.member_{name,value}(<json-member>)
$json.object_names(<json-object>)
$json.array_size(<json-array>)
$json.array_find(<json-array>, <json>)
$json.array_find_index(<json-array>, <json>)
$json.load(<path>)
$json.parse(<text>)
$json.serialize(<json>[, <indentation>])
For example, to load a JSON value from a file:
j = $json.load($src_base/board.json)
Or to construct it in a buildfile:
j = [json] one@1 two@([json] 2 3 4) three@([json] x@1 y@-1)
This can also be done incrementally with append/prepend:
j = [json_object]
j += one@1
j += two@([json] 2 3 4)
j += three@([json] x@1 y@-1)
Instead of using this JSON-like syntax, one can also specify valid JSON
input text:
j = [json] '{"one":1, "two":[2, 3, 4], "three":{"x":1, "y":-1}'
Besides the above set of functions, other handy ways to access components
in a JSON value are iteration and subscript. For example:
for m: $j
print $member_name($m) $member_value($m)
print ($j[three])
A subscript can be nested:
print ($j[two][1])
print ($j[three][x])
While a JSON value can be printed directly like any other value, the
representation will not be pretty-printed. As a result, for complex
JSON values, printing a serialized representation might be a more
readable option:
info $serialize($j)
