2024-02-20Add json_map and json_set buildfile value typesBoris Kolpackov1-1/+12
These expose the std::map<json_value,json_value> and std::set<json_value> types to buildfiles. New functions: $size(<json-set>) $size(<json-map>) $keys(<json-map>) Note that the $keys() function returns the list of map key as a json array. For example: m = [json_map] 2@([json] a@1 b@2) 1@([json] 1 2) s = [json_set] ([json] x@1 y@2) ([json] a@1 b@2) print ($m[2][b]) # 2 print ($s[([json] y@2 x@1)]) # true
2024-02-07Add $json.object_names() functionBoris Kolpackov1-15/+37
2024-02-07Tweak $json.*() function names and semanticsBoris Kolpackov1-19/+19
2024-02-07Use reverse to fundamental types semantics in $json.member_value()Boris Kolpackov1-1/+1
Feels like this is an equivalent context to subscript/iteration.
2024-02-07Add experimental support for JSON value typesBoris Kolpackov2-0/+228
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)
