JSON

 ToString
 format expression as JSON string

 Calling Sequence ToString(data,opts)

Parameters

 data - expression; data to be encoded as JSON opts - (optional) options as specified below

Options

 • style = one of block or inline.
 Specifies whether structured objects in Maple should be to multi-line (block) or single-line (inline) output in JSON.
 For example, if style=block a Maple list of three integers will produce a five-line JSON expression, while style=inline will produce a comma-delimited list on a single line.

Description

 • The ToString(data) command formats the expression data as JSON (stored as a Maple string).
 • The input data must be a structured expression made only using the base types string, truefalse, realcons, and extended_numeric and the container types list, rtable, table, record, set(equation), DataSeries, and DataFrame.

Examples

 > $\mathrm{with}\left(\mathrm{JSON}\right):$
 > $\mathrm{ToString}\left(\left[\mathrm{table}\left(\left["fruit"="orange","count"=23\right]\right)\right]\right)$
 ${"\left[\left\{"count": 23, "fruit": "orange"\right\}\right]"}$ (1)
 > $\mathrm{ToString}\left(\left\{"a"="b","c"=6.283185308\right\}\right)$
 ${"\left\{"a": "b", "c": 6.283185308\right\}"}$ (2)

Compatibility

 • The JSON[ToString] command was introduced in Maple 2015.
