  1. ((source:master/wacko/class/templatestescaper.php templatestescaper.php))
  1. ((source:master/wacko/class/templatestfilters.php templatestfilters.php))
  1. ((source:master/wacko/class/templatestsetter.php templatestsetter.php))

**((source:master/wacko/config/router.conf router.conf))**
%%// whole idea is to take URI path, _GET/_PUT/_SERVER data and other
// meta-data, then process rules in this file sequentially, which
// results in dispatched handler to process query,
// and all arguments extracted from URI for further usage by those handlers
// (e.g. you can extract parts of URI to _GET vars, etc.)


// 'language' guide:
// every line of code consists of regex which matched against URI, and
// actions, all separated by whitespace. there are no possibility to
// include whitespace in regex or action.
// regex will be matched against URI, on success all actions executed, on failure - we go for next regex.
// lines without regex is continuations for same regex, and will be executed sequentially if regex matched.

// every single action can succeed or fail. if any one fails - all
// variable assignments made by THIS line (even before failed action) is
// discarded, and we go to next line.

// two control action exist (all action line must succeed for them to act!)
//	_next!		-- jump to next regex (skip next action lines with empty regex)
//	_ok!		-- search terminated with success
// if no _ok! executed ever - search fails and 404 emitted

// that's all on control flow.

// main regex:
// http://php.net/manual/en/reference.pcre.pattern.syntax.php -- usual php preg_* regex syntax apply, including
// delimiters and options after trailing delimiter.
// convenience macros (defined by 'define' line, or supplied by wackowiki) expanded before matching.
// used as {macro} - to be referenced as $1-vars then, or {var=macro} - for inline assignment.
// macros cannot be used in ~-regexes

// VARIABLES:
//	$0..$9	- fields matched by main regex. $0 is complete match, $1 and later - corresponding (...) parts
//	$a..$j	- as $0..$9 but set by sub-matched (by ~ operator) patterns 
//	Gname	- _GET[name]
//	Pname	- _PUT[name]
//	Sname	- _SERVER[name]
//	others	- local variables
// predefined vars:
//	_tls		- 1 or 0, tls session
//	_uri		- parsed URI (it is matched against main regex, but can be changed by assignment)
//	_method		- _SERVER[REQUEST_METHOD]
//	_rewrite	- 1 or 0, mod_rewrite active
// usage of undefined variables considered a failure (if not masked by @ in VALUE expansion, see later)

// ACTIONS:
// similar format used for all actions (not all fields apply for every action, and just ignored):
//		VARIABLE[:FUNCTION]operatorVALUE

// value is a string, with expanded variables. expansions:
//	$0 .. $9 / $a .. $j -- see above
//	${name}
//	@$... format can be used to mask undefined variable error
//	$$ - replaced by $
//	$@ - replaced by @

// assignments:
// 	FUNCTIONs can be used: tolower | toupper | int
//	var=$1
//	var:tolower=$1
//	var?=$2				-- assign if not set
//	var!				== var=1
//	dbg=$1,$2,$3		-- Ut::dbg printer ;)

// pattern matching:
//	var~/regex/i			-- sets $a..$j on success
//	var!~/regex/i
//	var~hashid:[1-9]		-- hashid expansion, into $a...
//	var!~hashid:[1-9]

// comparisons:
//	FUNCTIONS can be used: int -- both args converted to int before comparison
//	var==12    var!=12    var:int<12    var>12    var<=12    var>=12

// others:
// var?					-- isset
// var-					-- unset
