/* Define context-specific regexes, one for every common token that ends the current context. An attempt has been made to search for the most common syntaxes first, thus maximizing performance. Syntaxes that begin with the same character are searched for at the same time. Wiki syntaxes from most common to least common: internal link [http:// named external link] {| table |} http:// bare external link =Heading= * unordered list # ordered list : indent ; small heading pre  horizontal line italic bold three tildes username four tildes signature five tildes timestamp &entity; The tag-matching regex follows the XML standard closely so that users won't feel like they have to escape sequences that MediaWiki will never consider to be tags. Only entities for characters which need to be escaped or cannot be      unambiguously represented in a monospace font are highlighted, such as       Greek letters that strongly resemble Latin letters. Use of other entities is discouraged as a matter of style. For the same reasons, numeric entities should be in hexadecimal (giving character codes in decimal only      adds confusion). Flags: g for global search, m for make ^ match the beginning of each line and $ the end of each line */   var breakerRegexBase = "\\[(?:\\[|(?:https?:|ftp:)?//|mailto:)|\\{(?:\\{\\{?|\\|)|<(?:[:A-Z_a-z\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u02FF\u0370-\u037D\u037F-\u1FFF\u200C\u200D\u2070-\u218F\u2C00-\u2FEF\u3001-\uD7FF\uF900-\uFDCF\uFDF0-\uFFFD][:\\w\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u02FF\u0370-\u037D\u037F-\u1FFF\u200C\u200D\u2070-\u218F\u2C00-\u2FEF\u3001-\uD7FF\uF900-\uFDCF\uFDF0-\uFFFD-\\.\u00B7\u0300-\u036F\u203F-\u203F-\u2040]*(?=/?>| )|!--[^]*?-->)|(?:https?://|ftp://|mailto:)[^\\s\"<>[\\]{-}]*[^\\s\",\\.:;<>[\\]{-}]|^(?:=|[*#:;]+|-{4,})|\\\\'\\\\'(?:\\\\')?|&(?:(?:n(?:bsp|dash)|m(?:dash|inus)|lt|e[mn]sp|thinsp|amp|quot|gt|shy|zwn?j|lrm|rlm|Alpha|Beta|Epsilon|Zeta|Eta|Iota|Kappa|[Mm]u|micro|Nu|[Oo]micron|[Rr]ho|Tau|Upsilon|Chi)|#x[0-9a-fA-F]+);|~{3,5}"; function breakerRegexWithPrefix(prefix) {       //the stop token has to be at the beginning of the regex so that it takes precedence over substrings of itself. //suck up newlines into the end token to avoid creating spans with nothing but newlines in them return new RegExp("(" + prefix + ")\n*|" + breakerRegexBase, "gm"); }   var defaultBreakerRegex           = new RegExp(breakerRegexBase, "gm"); var wikilinkBreakerRegex         = breakerRegexWithPrefix("]][a-zA-Z]*"); var namedExternalLinkBreakerRegex = breakerRegexWithPrefix("]"); var parameterBreakerRegex        = breakerRegexWithPrefix("}}}"); var templateBreakerRegex         = breakerRegexWithPrefix("}}"); var tableBreakerRegex            = breakerRegexWithPrefix("\\|}"); var headingBreakerRegex          = breakerRegexWithPrefix("\n"); var tagBreakerRegexCache         = {}; //browser workaround triggers var gecko  = ($.client.profile.layout == "gecko"); var presto = ($.client.profile.layout == "presto"); var trident = ($.client.profile.layout == "trident"); var webkit = ($.client.profile.layout == "webkit") && ($.client.profile.platform != "win"); function highlightSyntax {   	//Clear the timer for highlighting on an interval. //We do not want to get called while we are actually highlighting. clearInterval(highlightSyntaxIfNeededIntervalID); //Set the timer at the point we actually start so it catches all time, not // a subset of what is done. var startTime = Date.now; lastText = wpTextbox1.value; /* Backslashes and apostrophes are CSS-escaped at the beginning and all parsing regexes and functions are designed to match.
