====== Upgrading from older releases ====== ====== Upgrading from older releases ======
-===== 1.1.x → 1.2.0 =====+These are only changes that could affect existing templates/installations. You'll find all those instructions and additional information about changes/features in [[http://phptal.org/|release annoucements]]. 
 + 
 +===== 1.2.2 → 1.3.0 ===== 
 + 
 +''metal:fill-slot'' used outside ''metal:use-macro'' is no longer supported (it used to magically pre-fill slots for later use). Make sure you're using slots as described in the manual. 
 + 
 +Removed support for custom code generators using the old ''PHPTAL_Php_Tree'' interface. 
 + 
 +===== 1.2.0 → 1.2.2 ===== 
 + 
 +You don't need to ''include''/''require'' files other than ''PHPTAL.php''. You can remove any superfluous ''require''s.  
 + 
 +In case autoloading causes any problems and/or you want to use your own autoloader //instead of// PHPTAL's built-in one, execute this after loading ''PHPTAL.php'': 
 + 
 +   spl_autoload_unregister(array('PHPTAL','autoload')); // ugly workaround 
 + 
 +and then call ''PHPTAL::autoload()'' from your autoloader. 
 + 
 +===== 1.1.14 → 1.2.0 ===== 
 + 
 +You can automatically find most incompatible templates using the [[lint|lint tool]]. 
 + 
 +==== Entities and encodings ====
The biggest difference is in handling of entities. Entities are now unescaped before passing to expressions, i.e. ''${php:strlen('"')}'' “sees” just the quote character and returns ''1''. In previous versions entities were passed as-is to the expressions (and that example would return ''6''). The biggest difference is in handling of entities.

  * Only some 8-bit-based encodings are supported. If your encoding is not supported, you may get away with setting ISO-8859-1 instead.   * Only some 8-bit-based encodings are supported. If your encoding is not supported, you may get away with setting ISO-8859-1 instead.
-  * All constants except ''PHPTAL_VERSION'' have been removed. Remove any PHPTAL-specific ''define()''s and use class methods (available in earlier versions too) for configuration (e.g. ''$phptal->setPhpCodeDestination('/tmp/phptal/')'' for custom temp directory.)+==== Constants ====

 +  * ''PHPTAL_DIR'' is gone. PHPTAL now temporarily modifies ''include_path'' (this may change in the future). 
 + 
 +  * Don't include any PHPTAL's files before including ''PHPTAL.php''. 
 + 
 +==== XML ==== 
 + 
 +  * XML namespace of ''phptal:*'' attributes has changed from ''%%http://xml.zope.org/namespaces/phptal%%'' to ''%%http://phptal.org/ns/phptal%%''. 
 +  * Comments are required to be well-formed (''%%--%%'' is not allowed in comments.) Comments starting with ''%%<!--!%%'' are stripped from output. 
 +  * Duplicate attributes are not allowed and they must be separated with space. ''<b title=""title="">'' is doubly wrong. 
 + 
 +==== Other issues ==== 
 + 
 +  * use ''| nothing'' instead of ''| false'' to avoid getting zeros (''false'' is now printed as ''0''). 
 +  * ''tal:repeat'' doesn't “leak” variables to outer scope 
 +  * Internal DOM classes have been refactored. Your **custom TAL attributes could break** -- if they did, please complain on the mailinglist! 
 + 
 +===== 1.1.x → 1.1.14 ===== 
 + 
 +In 1.1.13 translation key like ''%%<p i18n:translate="'żółw'" />%%'' was interpreted as ''%%<p i18n:translate="'<C197><C188><C195>­<C179><C197><C130>w'">%%'' and you had to use ''msgid "<C197><C188><C195>­<C179><C197><C130>w"'' in your ''.po'' files. 
 + 
 +PHPTAL 1.1.14 stops doing this and keys are now left unchanged. The example above would simply expect ''msgid "żółw"'' in the ''.po'' file. 
 + 
 +If you don't want to change your .po files and want to keep old behaviour, then call ''setCanonicalize(true)'' of ''PHPTAL_GetTextTranslator'', e.g.:  
 + 
 +   $translator = new PHPTAL_GetTextTranslator(); 
 +   $translator->setLanguage(…); 
 +   $translator->setCanonicalize(true); // add this line 
 +   $phptal->setTranslator($translator); 
 + 
 + 
 +To upgrade templates, change ''<Cxxx>'' back to bytes. This code snippet will do it: ''%%preg_replace('/<C(\d+)>/e','chr("\1")',$po_file_content)%%''
-* Don't include any PHPTAL's files before including ''PHPTAL.php''.
