The // default is to do dynamic template expansion and no special action is // required for this to happen. // // class.FastTemplate.php3 Methods Not Implemented // // clear_parse // Same as clear. In fact, it was the same as clear in FastTemplate. // clear_all // If you really think you need this, try // unset $t; // $t = new Template ($path); // which gives the same effect. // clear_tpl // Use unload instead. This has the side effect of unloading all parent // and sibling templates which may be more drastic than you expect and // is different from class.FastTemplate.php3. This difference is // necessary since the only way we can force the reload of an embedded // template is to force the reload of the parent and sibling templates. // // class.FastTemplate.php3 Methods by Another Name // // The existence of these functions is a historical artifact. I // originally had in mind to write a functional equivalent from scratch. // Then I came my senses and just grabbed class.FastTemplate.php3 and // started hacking it. So, you can use the names on the right, but the // ones on the left are equivalent and are the names used in the original // class.FastTemplate.php3. // // parse --> subst // get_assiged --> getkey // assign --> setkey // clear_href --> unsetkey // clear_assign --> unsetkey // FastPrint --> xprint // class rFastTemplate { // File name to be used for debugging output. Needs to be set prior to // calling anything other than option setting commands (debug, debugall, // strict, dynamic) because once the file has been opened, this is ignored. var $DEBUGFILE = /tmp/class.rFastTemplate.php.dbg; // File descriptor for debugging output. var $DEBUGFD = -1; // Array for individual member functions. You can turn on debugging for a // particular member function by calling $this->debug(FUNCTION_NAME) var $DEBUG = array (); // Turn this on to turn on debugging in all member functions via // $this->debugall().

This can be // changed up until the time the first parse() is called. Well, you can // change it anytime, but it will have no effect on already loaded // templates. Also, if you have dynamic templates, the first call to parse // will load ALL of your templates, so changing it after that point will // have no effect on any defined templates. var $DYNAMIC = true; // Grrr. Dont try to break these extra long regular expressions into // multiple lines for readability.

The critical bit is that we need two parts: (1) the entire // match, and (2) the name of the dynamic template. The first part is // required because will do a strstr() to split the buffer into two // pieces: everything before the dynamic template declaration and // everything after. The second is needed because after finding a BEGIN // we will search for an END and they both have to have the same name of // we consider the template malformed and throw and error. // Both of these are written with PCRE (Perl-Compatible Regular // Expressions) because we need the non-greedy operators to insure that // we dont read past the end of the HTML comment marker in the case that // the BEGIN/END block have trailing comments after the tag name. var $REGEX_DYNBEG = /()/; // Regular expression which matches the end of a dynamic/inferior // template; see the comment about on the BEGIN match. var $REGEX_DYNEND = /()/; // Regular expression which matches a variable in the template. var $REGEX_VAR = /{[A-Za-z][-_A-Za-z0-9]*}/; // // Description // Constructor. // function rFastTemplate ($pathToTemplates = ) { // $pathToTemplates can also be an array of template roots, handled in set_root global $php_errormsg; if (!empty($pathToTemplates)) { $this->set_root ($pathToTemplates); } $this->DEBUG = array (subst => false, parse_internal => false, parse_internal_1 => false, parsed => false, clear => false, clear_dynamic => false, load => false); return $this; } // // Description // Set the name to be u
