I made a function that more or less works, but is not very elegant
def check_dimensions(registry : pint.UnitRegistry, src :QuantityOrUnitLike, dimensions : UnitLike, *contexts , **ctx_kwargs):
if contexts:
src_dim = registry.get_dimensionality(src)
dst_dim = registry.get_dimensionality(dimensions)
with registry.context(*contexts, **ctx_kwargs):
path = find_shortest_path(registry._active_ctx.graph, src_dim, dst_dim)
return bool(path)
elif registry._active_ctx:
src_dim = registry.get_dimensionality(src)
dst_dim = registry.get_dimensionality(dimensions)
path = find_shortest_path(registry._active_ctx.graph, src_dim, dst_dim)
return bool(path)
return src.check(dimensions)
ideally this would be a member function of the UnitRegistry?
BTW this works with 0.22, the master branch has the function _get_conversion_factor
which may be better, or at least simpler
from pint.
