* Large commit to make Pint more typing friendlyHernan Grecco2023-05-051-21/+34
| | | | | | | | | | | | | | | | | | | | | In this very large commit we tackle a few aspects of Pint that makes it difficult to do static typing. 1. Dynamic classes became static: Quantity and Unit are now (for the most part) static classes with a static inheritance. This allows mypy/pylance and other type checker to properly inspect them. 2. Added types through out all the code. (WIP) 3. Refactor minor parts of the code to make it more typing homogeneous. Catch a few potential bugs in the way. 4. Add several TODOs that need to be addressed in 0.23 5. Moved some group and system and context code out of the PlainRegistry 6. Moved certain specialized methods out of the PlainRegistry.

* Typing improvementsHernan Grecco2023-05-011-195/+309
| | | | | | | | | | | While there is still a lot of work to do (mainly in Registry, Quantity, Unit), this large PR makes several changes all around the code. There has not been any intended functional change, but certain typing improvements required code minor code refactoring to streamline input and output types of functions. An important experimental idea is the PintScalar and PintArray protocols, and Magnitude type. This is to overcome the lack of a proper numerical hierarchy in Python.

| | |/ | |/| | | | | | | | | | | | | | | | | | | Currently, as tokenize.tokenizer does not parse ° as a NAME, it is translated to " degree". However, the preceding space means that units with a ° in the middle, for example, Δ°C, cannot be parsed. Removing the preceding space fixes this, and does not appear to break any tests.

| * Final step to split the registry from the parserHernan2022-09-301-74/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overview: - All the code in facets is now independent of the definition textual format. In particular, defintions such as UnitDefinition, ContextDefinition an so on cannot be built directly from a string. (some functions are kept only temporarily to simplify but transition) Building Definition objects from string requires a parser that emits them. - The standart pint format is implemented in delegates/txt_parser using flexparser. Briefly each single line statement is mapped to a ParsedStatement class and each larger construct to a Block class. - The registry then has an adder function that takes a definition an incorporate it into the registry. A few nice features of this approach: 1. The Definition objects are standalone public objects, you can now build them in a programatic way and incorporate them to the registry using the define function that will dispatch to the correct adder: >>> new_unit = UnitDefintion( ....) >>> ureg.define(new_unit) # might be called add in the future No more being forced to use string definitions (but you can still use them if you want) 2. Composition over inheritance. The Registry does not know how to parse a definition, but it delegates this to another class which can be changed. This makes it very easy to write another parser (faster, simpler) o try out a completely different file format. 3. Error messages can be more meaningful. Backwards incompatible changes - is_base parameter Definitions is not needed any more. It is now computed automatically leading to a leaner experience and also avoiding incompatible states - alias for dimensionality has been removed (for now at least) The only one defined was speed as an alias of velocity. - (Context|Group|System).from_lines and Definition.from string have been rewritten in terms of the new parser. But will be likely removed in the future - Changing non_int_type is not possible after registry has been created - load_definition raises FileNotFoundError instead of a generic exception if the file was not found - the string representation of several definitions is now not so user friendly terms of the new parser. But will be likely removed in the future - Changing non_int_type is not possible after registry has been created - load_definition raises FileNotFoundError instead of a generic exception if the file was not found - the string representation of several definitions is now not so user friendly.
* | String NaN creation with correct non_int_typeConstantine Evans2022-10-091-1/+1
|/ | | | | | | Creating NaN-value quantities should take into account the non_int_type, and create a magnitude of the correct type. Not all common non_int_type choices support NaN (eg, Fraction does not); this will likely result in a ValueError in that case.

| * Improve infer_base_unit type compat and testingConstantine Evans2022-02-091-8/+18
| | | | | | | | | | | | | | infer_base_unit accepted a UnitLike, but could not actually accept a string or UnitsContainer. This uses to_units_container, and the registry paramater, to try to accept all inputs, and throws a ValueError if it can't.
| * Fix to_compact, infer_base_unit for non-float non_int_type (#1461)Constantine Evans2022-02-091-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | to_compact used math.log10, which converted non-float types to floats; this caused exceptions when using a non-integer type, like Decimal, that does not implement multiplication/division with floats, and generally changed non-integer types to floats. This addresses the problem by checking non_int_type. If non_int_type != float, it assumes that the type implements a log10 method, as Decimal does. infer_base_unit created a generic UnitsContainer, not a UnitsContainer specific to a registry; this allows specification of a registry, or uses the registry of the passed-in Quantity/UnitLike.
* | Remove UnitsContainer hash from pickle stateHernan2022-02-121-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting from Python 3.3, the hash value of an object has a random salt that is chosen at interpreter startup. Therefore, pickling and recovering and object hash is incorrect if the the dumpeed value will be used at a different interpreter run. Until this commit, a UnitsContainer that was pickled and then unpickled in a different interpreter would be wrongly consider as unequal. BREAKING CHANGE: This commit will break existing code that relies on keeping the hash across interpreters run. This should be very rare as will require to set the PYTHONHASHSEED value.
