"""
English pronoun mapping between 1st/2nd person and 3rd person perspective (and vice-versa).
This file is released under the Evennia regular BSD License.
(Griatch 2021)
Pronouns are words you use instead of a proper name, such as 'him', 'herself', 'theirs' etc. These
look different depending on who sees the outgoing string. This mapping maps between 1st/2nd case and
the 3rd person case and back. In some cases, the mapping is not unique; it is assumed the system can
differentiate between the options in some other way.

"""
Access function for determining the forms of a pronount from different viewpoints.
Args:
pronoun (str): A valid English pronoun, such as 'you', 'his', 'themselves' etc.
options (str or list, optional): A list or space-separated string of options to help
the engine when there is no unique mapping to use. This could for example
be "2nd female" (alias 'f') or "possessive adjective" (alias 'pa' or 'a').
pronoun_type (str, optional): An explicit object pronoun to separate cases where
there is no unique mapping. Pronoun types defined in `options` take precedence.
Values are
- `subject pronoun`/`subject`/`sp` (I, you, he, they)
- `object pronoun`/`object/`/`op` (me, you, him, them)
- `possessive adjective`/`adjective`/`pa` (my, your, his, their)
- `possessive pronoun`/`pronoun`/`pp` (mine, yours, his, theirs)
gender (str, optional): Specific gender to use (plural counts a gender for this purpose).
A gender specified in `options` takes precedence. Values and aliases are:
- `male`/`m`
- `female`/`f`
- `neutral`/`n`
- `plural`/`p`
viewpoint (str, optional): A specified viewpoint of the one talking, to use
when there is no unique mapping. A viewpoint given in `options` take
precedence. Values and aliases are:
- `1st person`/`1st`/`1`
- `2nd person`/`2nd`/`2`
- `3rd person`/`3rd`/`3`
Returns:
tuple: A tuple `(1st/2nd_person_pronoun, 3rd_person_pronoun)` to show to the one sending the
string and others respectively. If pronoun is invalid, the word is returned verbatim.
Note:
The capitalization of the original word will be retained.
