How to include my own units?

VSS standard catalog uses the units defined in this file. They are also described in the VSS documentation.

It is possible to replace the default units by the --units/-u parameter, see vspec documentation.

The syntax of the file with units shall follow this pattern:

puncheon:
  definition: Volume measure in puncheons (1 puncheon = 318 liters)
  unit: Puncheon
  quantity: volume
  allowed_datatypes: ['uint16', 'int16']
hogshead:
  definition: Volume measure in hogsheads (1 hogshead = 238 liters)
  unit: Hogshead
  quantity: volume
  allowed_datatypes: ['numeric']
