Functions

Escape

Plain simple JSON escape.

Examples

sample "string"\ => "sample \"string\"\\"

{"a": "test"} => "{\"a\": \"test\"}"

And so on.

Unescape

Plain simple JSON unescape, but it can unescape both some string and "some string".

Input MUST be valid JSON escaped string.

Examples

"test \"string\"\\n" => test "string"\n

test \"string\"\\n => test "string"\n

{\"a\": \"123\\n\"} => {"a": "123\n"}

And so on.

Recursive unescape

This is a bit tricky.

If input is "some string" or some string it behaves as simple unescape (see above).

If input is valid JSON (like {"a": 1}) or valid escaped JSON (like "{\"a\": \"string\"}" with or without outer quotes), it does:

• Parse input to JSON
• Recursively traverse all nodes
• For string nodes try parse string content as JSON and replace string value with object value

Examples

"{\"a\": \"string\"}" => {"a":"string"}

{\"a\": \"string\"} => {"a":"string"} (same as above but without outer quotes)

"{\"a\":1,\"b\":\"{\\\"c\\\": 1}\"}" => {"a":1,"b":{"c":1}}

{"a": "{\"b\":\"{\\\"c\\\": \\\"string\\\"}\"}"} => {"a":{"b":{"c":"string"}}}

And so on.
