Module:GetShortDescription

Module documentation[view] [edit] [history] [purge]

Not to be confused with Module:Get short description.

Usage

{{#invoke:GetShortDescription|main |name= |only= |prefer= |fallback= |lang_italic= |lang_nocat= |lang_size= |lang_cat= |lang_rtl= |lang_no= }}

name

By providing only the required page name (including namespace), the module will look for an explicit {{short description}} in that page, but if not found, will try to fetch the wikidata description. If neither are found, the result will be an empty string.

If the result is a wikidata description, and it is declared (at the source) as being of a foreign language (i.e. not en), the result will be appropriately formatted by Module:Lang (the module powering {{lang}}), in accordance with MOS:OTHERLANG; see #Foreign language wikidata descriptions (below).

Markup: {{#invoke:GetShortDescription|main |name=Wikipedia}}

Result: to sender

This is equivalent to stating |prefer=explicit; see #prefer (below).

only

Providing a value for |only= will limit the search to being only for the stated description. If no description is found, the result will be an empty string, unless a fallback is provided; see #fallback (below).

explicit

Markup: {{#invoke:GetShortDescription|main |name=Wikipedia |only=explicit }}

Result: to sender

wikidata

Markup: {{#invoke:GetShortDescription|main |name=Wikipedia |only=wikidata }}

Result: to sender

prefer

Providing a value for |prefer= will initiate the search for the stated description, but try for the alternative if none is found. If no description is found, the result will be an empty string, unless a fallback is provided; see #fallback (below).

explicit or wikidata

Markup: {{#invoke:GetShortDescription|main |name=Wikipedia |prefer=explicit }}

Result: to sender

wikidata or explicit

Markup: {{#invoke:GetShortDescription|main |name=Wikipedia |prefer=wikidata }}

Result: to sender

fallback

If a value for |fallback= is provided, and no description is found by the expressed route, the result will be the stated fallback.

only or fallback

Markup: {{#invoke:GetShortDescription|main |name=Example |only=explicit |fallback=This is a fallback }}

Result: to sender

prefer or fallback

Markup: {{#invoke:GetShortDescription|main |name=Example |prefer=wikidata |fallback=This is a fallback }}

Result: to sender

Foreign language wikidata descriptions

Should a wikidata description be retrieved, which is declared (at the source) as being of a foreign language (i.e. not en), per MOS:OTHERLANG, the return will be formatted as appropriate by Module:Lang by default. This may be disabled with |lang_no=yes or adjusted via the parameters for {{lang}}: |lang_italic=, |lang_nocat=, |lang_size=, |lang_cat= and |lang_rtl=; see lang's documentation for details.

Requiring this module

Instances when a table is returned

Providing a value for |objectify_alarm= will cause alarming messages (red informational messages) to be returned as tables.

Providing a value for |report_redlinks= will cause the return of a report instead of nothing in the event that the page named is nonexistent (i.e. a WP:REDLINK) and a search for a {{short description}} template is processed.

A table will also be returned in the event that the module is instructed to |prefer=explicit (its default), and returns a Wikidata description. If the reason for there being no explicit short description is because it was set to none; the table will include a value for table.none

See below for examples of these behaviors:

local getShortDescription = require( 'Module:GetShortDescription' ).main

local short_description = getShortDescription( {
  -- required
    name = 'page name',

  -- optional
    prefer = 'explicit' or 'wikidata',
    only = 'explicit' or 'wikidata',
    fallback = 'fallback',

    objectify_alarm = true,
    report_redlinks = true,

    lang_no = 'yes',

    -- {{lang}} options
    lang_italic = <yes, no, unset, invert, default>,
    lang_nocat = <yes, y, true, t, on, 1>,
    lang_size = <CSS font-size e.g. '1.5em'>,
    lang_cat = <no, n, false, f, off, 0>,
    lang_rtl = <no (default), yes>
} )

-- If we've requested to report_redlinks or to objectify_alarm then
if type( short_description ) == 'table' then
  if short_description.alarm then
    -- An alarming message has been returned
    local alarming_message = short_description.alarm
  elseif short_description.redlink then
    -- Do something about that
  elseif short_description.wikidata then
    -- A Wikidata description was returned without being explicitly requested
    local wikidata_description = short_description.wikidata
    if short_description.none then
      -- Because the explicit short desc was 'none'
    end
  end
end
