Documentation
In the json docs, it is said that "the most compact representation" for json is used if None is passed as indent to json.dump (the default behaviour), under the json.dump "Parameters" section.
However, under the description for the separators parameter, this is said: "If [separators is ]None (the default), separators defaults to (', ', ': ') if indent is None, and (',', ': ') otherwise. For the most compact JSON, specify (',', ':') to eliminate whitespace." The claim that the default behaviour gives "the most compact representation" is thus wrong; separators=(',', ':') is actually required as well.
Section concerned (source):
:param indent:
If a positive integer or string, JSON array elements and
object members will be pretty-printed with that indent level.
A positive integer indents that many spaces per level;
a string (such as ``"\t"``) is used to indent each level.
If zero, negative, or ``""`` (the empty string),
only newlines are inserted.
If ``None`` (the default), the most compact representation is used.
:type indent: int | str | None
:param separators:
A two-tuple: ``(item_separator, key_separator)``.
If ``None`` (the default), *separators* defaults to
``(', ', ': ')`` if *indent* is ``None``,
and ``(',', ': ')`` otherwise.
For the most compact JSON,
specify ``(',', ':')`` to eliminate whitespace.
:type separators: tuple | NoneI can open a PR if required.
