In this module, num_str is limited by calling functions to the integer values 1-99. The argument num_str must be known to be set before this function is called. local function ordinal_suffix (num_str) local lsd; -- least significant digit local suffixes = {['1'] = 'st', ['2'] = 'nd', ['3'] = 'rd'}; -- table of suffixes except 'th' if num_str:match ('^1[1-3]$') then -- check the 11-13 odd balls first to get them out of the way return num_str .. 'th'; -- 11th, 12th, 13th end lsd = num_str:match ('^%d?(%d)$'); -- all other numbers: get the least significant digit return num_str .. (suffixes[lsd] or 'th'); -- append the suffix from the suffixes table or default to 'th' end --2 |page= or |pages= parameter in . The arguments |param=page and |param=pages specify which of the cs1|2 parameters |page= or |pages= for which this function is to create a value. This function inspects the content of the |page= and |pages= parameters, along with the |param= specifier. From this information it creates a value appropriate for the specified |page= or |pages= parameter. Only one will have a value, the other will get an empty string. This function is called twice from ; once for each of cs1 |page= and |pages= parameters: |page=} |pages=} except for the lvalue and the rvalue assigned to |param=, the two calls must be identical else odd results. |page= or |pages= without a comma, hyphen, or en dash separator → cs1 |page= |page= or |pages= with a separator → cs1 |pages= Hyphen separator characters are converted to en dash characters. Any white space around hyphen and en dash separators is removed. If both |page= and |pages= are set, this function mimics cs1|2 and chooses |page=. Another function, page_error is required for error messaging because we don't want to dump css markup into a parameter value that will be included in the cs1|2 metadata. function p.make_page_param (frame) local args = getArgs(frame); local page_or_pages; page_or_pages = args.page or args.unnamed or args.pages; -- only one; prefer |page= if is_set (page_or_pages) then if 'pages' args.param then if page_or_pages:match ('[,%-–]') then -- only for |pages parameter page_or_pages mw.ustring.gsub (page_or_pages, '%s*[%-–]%s*', '–'); -- hyphen to en dash; remove spaces return page_or_pages; -- has separator character so make the parameter |pages else return ; -- no separator so value will be assigned to |page end elseif 'page' args.param then if page_or_pages:match ('[,%-–]') then -- only for |pages= parameter return ; -- has separator so value will be assigned to |pages= else return page_or_pages; -- no separator character so make the parameter |page= end else return ; -- |param= something else end end return ; -- if here no pagination or not correct |page= or |pages= parameter end --2 citation's metadata. } function p.page_error (frame) local args = getArgs(frame); if is_set (args.page) and is_set (args.pages) then return duplicate_page_error; -- both of |page= and |pages= are set else return ; end end --type= parameter using the values of the London Gazette |supp= and |display-supp= parameters Only limited |supp= values will set the type value.

This function assumes that supplements may have page numbering that are digits prefixed with one or two letters: B1, B41, RH2, etc; also assumes that regular issues have digit-only page numbers. Only limited |supp= values will set the page number path element.
