incompatibility with PHP 8.0

[renatopancheri]

Hi,

running dokuwiki with PHP 8.0 i get this error:

PHP Fatal error: Uncaught Error: Call to undefined function create_function() in /var/www/local_https/dokuwiki/lib/plugins/ckgedit /action/edit.php:229 Stack trace: #0 /var/www/local_https/dokuwiki/lib/plugins/ckgedit/action/edit.php(174): action_plugin_ckgedit_edit->_preprocess() #1 /var/www/local_https/dokuwiki/inc/Extension/EventHandler.php(81): action_plugin_ckgedit_edit->ckgedit_edit() #2 /var/www/local_https/dokuwiki/inc/Extension/Event.php(72): dokuwiki\Extension\EventHandler->process_event() #3 /var/www/local_https/dokuwiki/inc/Extension/Event.php(128): dokuwiki\Extension\Event->advise_before() #4 /var/www/local_https/dokuwiki/inc/Extension/Event.php(195): dokuwiki\Extension\Event->trigger() #5 /var/www/local_https/dokuwiki/inc/template.php(84): dokuwiki\Extension\Event::createAndTrigger() #6 /var/www/local_https/dokuwiki/lib/tpl/dokuwiki/main.php(59): tpl_content() #7 /var/www/local_https/dokuwiki/inc/actions.php(27): include('...') #8 /var/www/local_https/dokuwiki/doku.php(122): act_dispatch() #9 {main}

looks like create_function has been deprecated in PHP 7.2 and dropped in PHP 8.0: https://www.php.net/manual/en/function.create-function.php

i've found this repository: https://github.com/lombax85/create_function from a guy that re-created this function for PHP8, i literally copy pasted the helper.php in a file and added: require_once(DOKU_INC . 'lib/plugins/ckgedit/create_function.php'); at the start of helper.php and it seems to work fine

The conversion from create_function to anonymous function is ongoing, in the anon_func branch. There are many instances, and each has to be tested.

The anon_func branch should now be completed. Perhaps you can try it out. Since there were so many changes, it would be helpful to have it tested before integrating it into the main distribution.
