JSONAST
▪
A JSON object is a ; a JSON array is an ; each object member is a pairing the key leaf with the value.
"Object"
"Array"
":"
▪
A keeps the literal source text, including the surrounding quotes of a string (, not ) and the raw digits of a number (, not ); values are only interpreted in the mode.
"\"a\""
"a"
"42"
42
▪
Number leaves are tagged or from the literal form - a decimal point or exponent makes it .
"Integer"
"Real"
"Real"
▪
Every node carries a span in its metadata, a line-column pair . A leaf spans its own text; a spans its content (the brackets themselves are not included), so a multi-line input gives a span whose endpoints sit on different lines.
"Source"
CodeParser
{{startLine,startCol},{endLine,endCol}}

runs the same over instead, folding to a native Wolfram value. The grammar is written once; only the algebra differs.
