No direct template access

Extracts short description text from a named template in the named article when that template is found in article

wiki source.

Requires three arguments:

frame: frame object required to preprocess template_name.

article_title: the name of the article to inspect - correct spelling and captialization is required.

template_names_tbl: a single template name (a string) or a table of one or more template names all without

namespace to be inspected - correct spelling and captialization is required.

Returns two values:

on success, returns the short description text and true.

on failure, returns error message and nil.

No direct template access

Extracts short description text from {{short description}} template when that template is found in article wiki

source; searches for both the long name (short description) and the short-name redirect (SHD); if both are present

long name controls; if multiples of the same name are present, the first-found controls.

Requires one argument:

article_title - the name of the article to be inspected.

Returns:

on success, returns the short description text; error message else

]]

local function extract_from_article(article_title)

local content = mw.title.new(article_title):getContent(); -- read the unparsed article source

if (not content) then

return 'error: no article: ' .. article_title .. '';

end

local start = string.find(content, '{{%s*[Tt]elevision episode short description') -- find the start of {{Short description}} template

if (not start) then

return 'error: no short description in: ' .. article_title .. '';

end

local text = content:match('%b{}', start); -- get the short description template; start points to first { of the template

if (not text) then

return 'error: failed to extract short description template from ' .. article_title .. '';

end

text = text:match('^[^|}]+|%s*(.+)%s*}}$'); -- strip '{{template name|' and '}}'; trim leading and trailing whitespace

return text and text or 'error: no short description text in: ' .. article_title .. '';

end

Template entry point:

{{#invoke:extract short description|extract_short_description}}

Search for and return text that is used by the {{short description}} template.

When neither of |template= and {{{2|}}} are set, this code will look in the article wiki source;

when set, this code look inside the named template.

Requires two arguments:

{{{1}}} or |article=: required; name of wiki article from which to extract the short description.

{{{2}}} or |template=; optional; name of template that holds the {{short description}} template.

Returns:

on success, returns the short description text; error message else.
