Syntax

JSON CLOSE, <id>

JSON PARSE, <id>, <text>

JSON LOADFILE, <id>, <filename | url>

JSON SAVEFILE, <id>, <filename> {, PRETTY}

JSON SET, <id>, <path>, <value>

JSON SETRAW, <id>, <path>, <json>

JSON ADD, <id>, <path>, <value>

JSON DELETE, <id>, <path>

JSON CLEAR, <id>

Description

This command is used when working with JSON documents. The document handle <id> is created with @NEW(JSON). The options are:

JSON CLOSE,... Releases the JSON document with handle <id>.
JSON PARSE,... Parses the JSON <text> (typically an AI or HTTP response held in a variable) into the document. OK is false if the text is not valid JSON.
JSON LOADFILE,... Loads a document from disk, or from an HTTP/HTTPS URL (a GET request). OK is false if unsuccessful.
JSON SAVEFILE,... Writes the document to <filename>, compact by default or indented if PRETTY is given.
JSON SET,... Sets a string value at <path>, creating any missing objects along the way.
JSON SETRAW,... Sets a raw JSON value at <path> (a number, boolean, object or array).
JSON ADD,... Appends an element to the array at <path> (creating the array if needed).
JSON DELETE,... Removes the key or element at <path>.
JSON CLEAR,... Resets the document to an empty object.

Paths use the dotted notation described under JSON documents (users.0.name).

OK

As documented above. OK is false (and the document is left unchanged) if a parse fails or a file cannot be read or written. Referring to a document that has not been loaded sets an error.

Example

%h = @new(json)
json set,%h,user.name,John Smith
json setraw,%h,user.age,43
json add,%h,user.roles,admin
json savefile,%h,user.json,PRETTY
json close,%h
