data, displayed in a background of the color of the game, or a very light gray
if the game has no color.

Arguments:
    - data: the data of an abbreviation, from module Sigle/data.
    - makeText: the function creating the text to be displayed. It takes the
        abbreviation of a single game, and returns the text to be displayed
        in the link. Defaults to tostring.
    - makeColors: the function returning the colors to be used. It takes the
        color name as an argument, and returns the background and text color
        to be used in the link. Defaults to colorAndText.

This function takes as input a color as found in the elements if display key
in abbreviation data. It returns two hexadecimal colors: the first one is the
passed color one, the second one is the color the text should have if the first
color is used as a background.

The color can be passed in the following formats. A named color, in which case
the normale shade will be returned. An hexadecimal, that will be returned
unchanged: however, in this case the text color will always be black. Nil, that
implies returning a very light gray and black, as background and text color
respectively.

Arguments:
    - color: input color, as found in display keys items.

This function concatenates the string representation of the passed
abbreviations, as found in the given data module. Every non-found abbreviaton
will have the empty string as its string representation.

Arguments:
    - abbrs: The abbreviations to be merged, as a space separated string or as
        a table
    - dataModule: The data module holding the content that will be
        concatenated.

This function maps over all abbreviations in Sigle/data. Its main purpose is
increased efficiency, since the client modules can avoid requiring Sigle/data,
which is therefore mw.loaded here only once.

This function maps over the display key of every game in the passed
abbreviation data. The results of the mapping are concatenated for every
display property, so that the returned table is one-dimensioned.

Arguments:
    - data: The source abbreviation data.
    - makeText: The mapping function. It takes as parameters the two elements
        of display key elements, that is the abbreviation and the color of a
        game. Must return a string.

Return:
    - A list of string, each one resulting from the concatenation of the items
        in the display key of a game, after mapping.

--[[

This function returns a list of links from the passed abbreviation data. The
links target is the page in the link key of every game in the data, while the
displayed text is obtained by mapping with the specified function.

Arguments:
    - data: The source abbreviation data.
    - makeText: The mapping function that produces the text to be displayed
        for every game in the abbreviation data. Takes such data as an
        argument, and must return a table with the text for every game in the
        data, in the same order as they are in the abbreviation data.

Return:
    - A list of links, one for each game in the abbreviation data.

This function returns a table containing interface functions, both for lua and
wikicode. Wikicode interfaces are named after abbreviations, while lua
interfaces have the 'Lua' and '_lua' suffixes.

The interfaces are created by means of makeInterfaces, that must return at
least the lua function: the wikicode interface defaults to the standard one
calling the lua interface as in Wikilib.stdWikicodeInterface.

Arguments:
    - makeInterfaces: This is the functino used to generate the lua interfaces,
        and optionally the wikicode ones. Its parameters are abbreviation data
        and its abbreviation. Must return the lua function and optionally the
        wikicode one.

This function generates a WikiCode interface for client modules. As explained
below, the interface takes no arguments other than optional abbreviations.

This function is meant to be named after an abbreviation, and can take an
arbitrary number of additional abbreviations as arguments, even
space-seaparated within a single argument. For this intended use, an example
call would be:

{{#invoke: ClientModule | abbr0 | abbr1 | abbr2 abbr3 | abbr4 }}

The returned function processes every abbreviaton, including the one it is
meant to be named after, via makeGame, and then the resulting table is passed
on to postProcess for the final processing before returning the value to
WikiCode.

Arguments:
    - abbr: the abbreviaton this function is meant to be bound to, that will
        always be prepended to the passed arguments.
    - makeAbbrev: this function is used to generate data for a single
        abbreviation. It takes the data of such abbreviation in Sigle/data,
        and returns whatever postProcess is able to handle as its list items.
    - postProcess: this function is used for processing the data generated from
        the abbreviations before the final result is given back to WikiCode.
        It takes a list of whatever makeAbbrev returns, and should return a
        string. Defaults to table.concat.

--[[

This function generates a lua interface for client modules. As explained
below, the interface takes a single table, containing both arbitrary arguments
and extra abbreviations.

This function is meant to be named after an abbreviation, and takes as
argument a single table. One of the keys is meant to store some extra
abbreviations, either as a table or as a space-separated list. The other items
are the other arguments that the function needs.

Some example calls:

myModule.abbr0{games = {'abbr1', 'abbr2'}, arg1, arg2, arg3)
myModule.abbr0{games = 'abbr1 abbr2', arg1, arg2, arg3)
myModule.abbr0{arg1, arg2, arg3}

The returned function processes every abbreviaton, including the one it is
meant to be named after, via makeGame, and then the resulting table is passed
on to postProcess for the final processing before returning the value to
WikiCode.

Arguments:
    - abbr: the abbreviaton this function is meant to be bound to, that will
        always be prepended to the passed arguments.
    - abbrKey: the key of the table the abbreviations are stored at.
        Defaults to 'games'
    - makeAbbrev: this function is used to generate data for a single
        abbreviation. It takes the data of such abbreviation in Sigle/data and
        the fixed final arguments packed in a table. It returns whatever
        postProcess is able to handle as its list elements.
    - postProcess: this function is used for processing the data generated from
        the abbreviations before the final result is given back to WikiCode.
        It takes the fixed final arguments packed in a table and a list of
        whatever makeAbbrev returns, and should return a string. Defaults to
        a function concatenating the second argument.

This function returns a proxy for abbreviation functions, meant to be called
from wikicode only. Unlike other abbreviation functions, this proxy doesn't
need to be named after any abbreviation, and takes all the abbreviations as
arguments. It then calls the abbreviation function named after the first
abbreviation in its arguments, passing along all the other ones.

The abbreviations can be given as positional arguments, even space-separated
within single arguments. Alternatively, the abbreviations can be passed as a
space-separated string in a named argument.

Arguments:
    - abbrFuncts: the table containing the abbreviation functions.
    - abbrsKey: optional, the name of the named arguments the abbreviations
        will be looked for in. When omitted, the first positional argument is
        used instead.
    - proxyKey: optional, specifies the key the proxy is set to in abbrFuncts.
        If set to false, abbrFuncts is left untouched. Defaults to '_abbr'.
