28.0.50; json-parse-string missing support for key-less json strings |
|
Date: |
Sat, 13 Feb 2021 13:04:09 +0100 |
The `json-read-from-string' function doesn't support json strings that
only contain a single value, which is neither a list nor a dict, e.g.
"123"
or
"\"abc\""
However, `json-read-from-string' doesn't have this issue:
(require 'json)
(json-read-from-string "\"abc\"")
-> "abc"
(json-parse-string "\"abc\"")
-> progn: could not parse JSON stream: "'[' or '{' expected near '\"abc\"'",
"<string>", 1, 5, 5
Note that strings that neither start with [ nor { are valid JSON objects
according to the JSON schema.
Since the docstring of `json-parse-string' mentions `json-serialize' as
essentially being the reverse operation of `json-parse-string', I've
tried to serialize a lisp string:
(json-serialize "abc")
-> progn: Wrong type argument: json-value-p, "abc"
I would also expect this `json-serialize' call to work.
