Search and multimatch handling
This module allows for overloading two functions used by Evennia's
search functionality:
at_search_result:
This is called whenever a result is returned from an object
search (a common operation in commands). It should (together
with at_multimatch_input below) define some way to present and
differentiate between multiple matches (by default these are
presented as 1-ball, 2-ball etc)
at_multimatch_input:
This is called with a search term and should be able to
identify if the user wants to separate a multimatch-result
(such as that from a previous search). By default, this
function understands input on the form 1-ball, 2-ball etc as
indicating that the 1st or 2nd match for "ball" should be
used.
This module is not called by default. To overload the defaults, add
one or both of the following lines to your settings.py file:
SEARCH_AT_RESULT = "server.conf.at_search.at_search_result"
SEARCH_AT_MULTIMATCH_INPUT = "server.conf.at_search.at_multimatch_input"
"""
def at_search_result(msg_obj, ostring, results, global_search=False,
nofound_string=None, multimatch_string=None, quiet=False):
"""
Called by search methods after a result of any type has been found.
Takes a search result (a list) and
formats eventual errors.
msg_obj - object to receive feedback.
ostring - original search string
results - list of found matches (0, 1 or more)
global_search - if this was a global_search or not
(if it is, there might be an idea of supplying
dbrefs instead of only numbers)
nofound_string - optional custom string for not-found error message.
multimatch_string - optional custom string for multimatch error header
quiet - work normally, but don't echo to caller, just return the
results.
Multiple matches are returned to the searching object
as a list of results ["1-object", "2-object","3-object",...]
A single match is returned on its own.
"""

def at_multimatch_input(ostring):
"""
This parser will be called by the engine when a user supplies
a search term. The search term must be analyzed to determine
if the user wants to differentiate between multiple matches
(usually found during a previous search).
This method should separate out any identifiers from the search
string used to differentiate between same-named objects. The
result should be a tuple (index, search_string) where the index
gives which match among multiple matches should be used (1 being
the lowest number, rather than 0 as in Python).
The default parser will intercept input on the following form:
2-object
This will be parsed to (2, "object") and, if applicable, will tell
the engine to pick the second from a list of same-named matches of
objects called "object".
Ex for use in a game session:
> look
You see: ball, ball, ball and ball.
> get ball
There where multiple matches for ball:
1-ball
2-ball
3-ball
4-ball
> get 3-ball
You get the ball.
