Locates and returns the first set value in a table of values where the order established in the table, left-to-right (or top-to-bottom), is the order in which the values are evaluated. Returns nil if none are set.

This version replaces the original 'for _, val in pairs do' and a similar version that used ipairs. With the pairs version the order of evaluation could not be guaranteed. With the ipairs version, a nil value would terminate the for-loop before it reached the actual end of the list.

Adds a category to z.properties_cats using names from the configuration file with additional text if any.

does this thing that purports to be a uri scheme seem to be a valid scheme? The scheme is checked to see if it is in agreement with http://tools.ietf.org/html/std66#section-3.1 which says: Scheme names consist of a sequence of characters beginning with a

--[=[-------------------------< I S _ D O M A I N _ N A M E >--------------------------------------------------

Does this thing that purports to be a domain name seem to be a valid domain name?

Syntax defined here: http://tools.ietf.org/html/rfc1034#section-3.5 BNF defined here: https://tools.ietf.org/html/rfc4234 Single character names are generally reserved; see https://tools.ietf.org/html/draft-ietf-dnsind-iana-dns-01#page-15; see also Single-letter second-level domain list of tlds: https://www.iana.org/domains/root/db

rfc952 (modified by rfc 1123) requires the first and last character of a hostname to be a letter or a digit. Between the first and last characters the name may use letters, digits, and the hyphen.

Also allowed are IPv4 addresses. IPv6 not supported

domain is expected to be stripped of any path so that the last character in the last character of the tld. tld is two or more alpha characters. Any preceding '//' (from splitting a url with a scheme) will be stripped here. Perhaps not necessary but retained incase it is necessary for IPv4 dot decimal.

Return true if a parameter value has a string that begins and ends with square brackets [ and ] and the first non-space characters following the opening bracket appear to be a url. The test will also find external wikilinks that use protocol relative urls. Also finds bare urls.

The frontier pattern prevents a match on interwiki links which are similar to scheme:path urls. The tests that find bracketed urls are required because the parameters that call this test (currently |title=, |chapter=, |work=, and |publisher=) may have wikilinks and there are articles or redirects like '//Hus' so, while uncommon, |title=[[1]] is possible as might be en://Hus.

|script-title= holds title parameters that are not written in Latin based scripts: Chinese, Japanese, Arabic, Hebrew, etc. These scripts should not be italicized and may be written right-to-left. The value supplied by |script-title= is concatenated onto Title after Title has been wrapped in italic markup.

Regardless of language, all values provided by |script-title= are wrapped in ... tags to isolate rtl languages from the English left to right.

|script-title= provides a unique feature. The value in |script-title= may be prefixed with a two-character ISO639-1 language code and a colon: |script-title=ja:*** *** (where * represents a Japanese character) Spaces between the two-character code and the colon and the colon and the first script character are allowed: |script-title=ja : *** *** |script-title=ja: *** *** |script-title=ja :*** *** Spaces preceding the prefix are allowed: |script-title = ja:*** ***

The prefix is checked for validity. If it is a valid ISO639-1 language code, the lang attribute (lang="ja") is added to the tag so that browsers can know the language the tag contains. This may help the browser render the script more correctly. If the prefix is invalid, the lang attribute is not added. At this time there is no error message for this condition.

Supports |script-title= and |script-chapter=

For Vancouver Style, author/editor names are supposed to be rendered in Latin (read ASCII) characters. When a name uses characters that contain diacritical marks, those characters are to converted to the corresponding Latin character. When a name is written using a non-Latin alphabet or logogram, that name is to be transliterated into Latin characters. These things are not currently possible in this module so are left to the editor to do.

This test allows |first= and |last= names to contain any of the letters defined in the four Unicode Latin character sets C0 Controls and Basic Latin 0041–005A, 0061–007A C1 Controls and Latin-1 Supplement 00C0–00D6, 00D8–00F6, 00F8–00FF Latin Extended-A 0100–017F Latin Extended-B 0180–01BF, 01C4–024F

|lastn= also allowed to contain hyphens, spaces, and apostrophes. (http://www.ncbi.nlm.nih.gov/books/NBK7271/box/A35029/) |firstn= also allowed to contain hyphens, spaces, apostrophes, and periods

This original test: if nil == mw.ustring.find (last, "^[A-Za-zÀ-ÖØ-öø-ƿDŽ-ɏ%-%s%']*$") or nil == mw.ustring.find (first, "^[A-Za-zÀ-ÖØ-öø-ƿDŽ-ɏ%-%s%'%.]+[2-6%a]*$") then was written ouside of the code editor and pasted here because the code editor gets confused between character insertion point and cursor position. The test has been rewritten to use decimal character escape sequence for the individual bytes of the unicode characters so that it is not necessary to use an external editor to maintain this code.

Validates language names provided in |language= parameter if not an ISO639-1 or 639-2 code.

Returns the language name and associated two- or three-character code. Because case of the source may be incorrect or different from the case that WikiMedia uses, the name comparisons are done in lower case and when a match is found, the Wikimedia version (assumed to be correct) is returned along with the code. When there is no match, we return the original language name string.

mw.language.fetchLanguageNames(<local wiki language>, 'all') returns a list of languages that in some cases may include extensions. For example, code 'cbk-zam' and its associated name 'Chavacano de Zamboanga' (MediaWiki does not support code 'cbk' or name 'Chavacano'. Most (all?) of these languages are not used a 'language' codes per se, rather they are used as sub-domain names: cbk-zam.wikipedia.org. These names can be found (for the time being) at https://phabricator.wikimedia.org/diffusion/ECLD/browse/master/LocalNames/LocalNamesEn.php

Names but that are included in the list will be found if that name is provided in the |language= parameter. For example, if |language=Chavacano de Zamboanga, that name will be found with the associated code 'cbk-zam'. When names are found and the associated code is not two or three characters, this function returns only the Wikimedia language name.

Check archive.org urls to make sure they at least look like they are pointing at valid archives and not to the save snapshot url or to calendar pages. When the archive url is 'https://web.archive.org/save/' (or http://...) archive.org saves a snapshot of the target page in the url. That is something that Wikipedia should not allow unwitting readers to do.

When the archive.org url does not have a complete timestamp, archive.org chooses a snapshot according to its own algorithm or provides a calendar 'search' result. WP:ELNO discourages links to search results.

This function looks at the value assigned to |archive-url= and returns empty strings for |archive-url= and |archive-date= and an error message when: |archive-url= holds an archive.org save command url |archive-url= is an archive.org url that does not have a complete timestamp (YYYYMMDDhhmmss 14 digits) in the correct place otherwise returns |archive-url= and |archive-date=

There are two mostly compatible archive.org urls: //web.archive.org/<timestamp>... -- the old form //web.archive.org/web/<timestamp>... -- the new form

The old form does not support or map to the new form when it contains a display flag. There are four identified flags ('id_', 'js_', 'cs_', 'im_') but since archive.org ignores others following the same form (two letters and an underscore) we don't check for these specific flags but we do check the form.

This function supports a preview mode. When the article is rendered in preview mode, this funct may return a modified archive url: for save command errors, return undated wildcard (/*/) for timestamp errors when the timestamp has a wildcard, return the url unmodified for timestamp errors when the timestamp does not have a wildcard, return with timestamp limited to six digits plus wildcard (/yyyymm*/)
