Upgrading

This guide takes you through the steps needed to migrate from Mako 6.0.x to 6.1.x.

Error handling

The ErrorHandler::disableLoggingFor() method has been deprecated. Use the new ErrorHandler::dontLog() method or the new application.error_handler.dont_log config key instead.

Note that the method will not be removed until version 7.0 but it's still a good idea to update your code now.

Views

The {{$foo || 'Default'}} and {{$foo or 'Default'}} syntax has been deprecated since it will cause unexpected behaviour when printing the output of a ternary expression using the || and or operators. Use the new {{$foo, default: 'Default'}} syntax instead.

The new default syntax also has a small change in behaviour. It will print out the value for variables containing 0, 0.0 and "0".

You can use the following regex to find your echo tags that still use the deprecated syntax:

\{\{([^view:][^}]+)((\|\|){1}|\s+(or)\s+)([^}]+)\}\}

Note that the old syntax will not be removed until version 7.0 but it's still a good idea to update your templates now.
