mistql package exports

Export	type	Description
query	(query: string, data: any) => any	The query interface for MistQL
__version__	str	The current version of MistQL installed

Type correspondence between Python and MistQL

Separate from the specification of the language, the python implementation maps from Python types to MistQL types in a specific manner, as documented by the table below. As the following is NOT part of the language, rather the library, the correspondence may change with further releases of the mistql package, following semver.

Note that this is generally very restrictive in what it allows, but can be easily expanded as necessary. For examples, iterables as a whole may, outside of specific cases, be casted directly to MistQL array types.

If this correspondence doesn't work for you for some reason, please open an issue and describe the situation carefully. This correspondence is easier to change than the language itself.

Value	MistQL Value	Notes
int	number	Infinity and NaN casted to null
float	number
boolean	boolean
string	string
dict	object
None	null
list	array
tuple	array
datetime.date	date.isoformat()
datetime.time	time.isoformat()
datetime.datetime	datetime.isoformat()
Anything else	Error
