Release 2.2 - 2020-02-02

Type Changes Bye
Deprecated 2.1 flag velocimacro.arguments.preserve_literals in favor of the new valocimacro_enable_bc_mode flag, which will also, like 1.7 does, use global context values as defaults for missing macro arguments which do not have an explicit default value. . cbrisson
Fixed regression: Macro arguments names cannot collide with external references names . Fixes VELOCITY-926. cbrisson
Fixed macro calls without parenthesis eating the following newline in BC mode . Fixes VELOCITY-925. cbrisson

Added the runtime.log.track_locations debugging flag (disabled by default), which:
  • display a VTL stack trace on any error
  • Implement template location tracking with slf4j MDC tags: Once activated, an MDC-aware logger will be able to display the file , line and column MDC tags
. Fixes VELOCITY-916.
Added the following 1.7.x backward compatibility flags:
  • event_handler.invalid_references.quiet - warn on invalid quiet references
  • event_handler.invalid_references.null - warn on null references

  3. if directive.if.emptycheck is false (true by default), stop here and return true.
  4. check for emptiness:
    • return whether an array is empty.
    • return whether isEmpty() is false (covers String and all Collection classes).
    • return whether length() is zero (covers CharSequence classes other than String).
    • returns whether size() is zero.
    • return whether a Number strictly equals zero.
  5. check for emptiness after explicit conversion methods:
    • return whether the result of getAsString() is empty (and false for a null result) if it exists.
    • return whether the result of getAsNumber() strictly equals zero (and false for a null result) if it exists.
Reviewed event handling API:
  • added a Context argument for all events

Removed references to ExtProperties from the engine configuration API. . cbrisson
Default encoding is now UTF-8. . cbrisson
Make Velocity use the base logger namespace 'org.apache.velocity' unless specified with in the configuration, and have the runtime instance log with this base namespace, and other modules log with children namespaces:

Change the scoping behavior of Velocity, keeping it optional (everything global scoped by default) but now providing an explicit namespace in content-containing directives (like macros, #foreach, #parse, etc.) in which references that should stay local may be kept. This is accompanied by numerous related changes, including: <ul> <li>A Scope reference can now be automatically made available within each content directive: <ul> <li>$template in Template.merge and #parse content<li> <li>$macro in #macro</li> <li>$foreach in #foreach</li> <li>$evaluate in #evaluate or Velocity.evaluate(...) content</li> <li>$define in #define</li> <li>$&lt;amacro&gt; in #@&lt;amacro&gt; (where &lt;amacro&gt; is the name of a macro being called with a body)</li> </ul> </li> <li>For performance and compatibility these are all off by default, *except* for $foreach. The others may be enabled by setting a velocity property like: <br/><code>macro.provide.scope.control = true</code></li> <li>When scopes of the same type are nested make the parent Scope available through the child (e.g. $foreach.parent or $foreach.topmost).</li> <li>When a Scope reference overrides an existing reference that is not a Scope, make it available through the Scope (e.g. $foreach.replaced).</li> <li>Made #break work in any of the above scopes to exit the most immediate one, unless a different scope is provided as an argument (e.g. #break($macro) or #break($foreach.topmost)).</li> <li>Deprecated $velocityCount; please use $foreach.count or $foreach.index.</li> <li>Deprecated $velocityHasNext; please use $foreach.hasNext, $foreach.first or $foreach.last</li> <li>Deprecated velocimacro.context.localscope setting; please get/set local #macro references as members of the provided $macro scope control instead. (e.g. #set( $ = 'bar' ) and $ ).</li> <li>Deprecated directive.evaluate.context.class setting; please get/set local #evaluate references as members of the provided $evaluate scope control instead. (e.g. #set( $ = 'bar' ) and $ ).</li> </ul> All of the deprecated features will be removed in Velocity 2.0. . Fixes VELOCITY-704. nbubna
Calling #set on a macro argument (for which a #set-able reference was passed) will no longer propagate the new value to the original reference, but merely set the value of the macro argument reference. This was an obscure, infrequently used feature and was decided to be more problematic and unpredictable than useful. . Fixes VELOCITY-681. nbubna
In strict mode attempts to render references that evaluate to null will throw an exception. In the user wishes to suppress the exception and render nothing then the reference can be preceeded with '$!' as in $!foo. . Fixes VELOCITY-688. byron
The non default VelocityEngine construtors now do not initialize the runtime system so that properties may be set after construction. Also fixes an Initialization race condition. . Fixes VELOCITY-673. byron
Make velocimacro.arguments.strict=true work with block macros. . Fixes VELOCITY-685. Thanks to Jarkko Viinamäki. nbubna
Added a property for changing escape behavior such that putting a forward slash before a reference or macro always escapes the reference or macro and absorbs the forward slash regardless if the reference or macro is defined. . Fixes VELOCITY-623. byron

Add support for calling velocimacros with body content by prefixing the macro name with @. (e.g. #macro( bold )<strong>$bodyContent</strong>#end #@bold()any valid VTL here#end) The $bodyContent reference may be renamed via a velocimacro.body.reference setting in your . Fixes VELOCITY-666. Thanks to Jarkko Viinamaki. nbubna
Added #[[this is included in output but not parsed]]# syntax to replace and deprecate the much more limited #literal directive (which required parse-able content). . Fixes VELOCITY-661. Thanks to Jarkko Viinamaki. nbubna
Re-implement #stop so that it stops template execution and rendering. This Also addresses a performance bottleneck detected in the old implementation. #stop is a general use directive now, and not just for debugging. . Fixes VELOCITY-663. byron
Reduce performance bottleneck with the referenceInsert event handler call . Fixes VELOCITY-662. byron
Better error reporting when toString() throw an exception when testing an #if conditional. For example #if($foo) . Fixes VELOCITY-656. byron
Added bracketed index syntax, $foo[0], or #set($foo[0] = 1) . Fixes VELOCITY-406. byron
Removed java.lang.Exception from throws clause of Velocity and VelocityEngine API. Also removed IOException so that all method calls use unchecked exceptions. . Fixes VELOCITY-659. byron

When #include was followed by #parse with the same file name, a ClassCastException was thrown. . Fixes VELOCITY-98. Thanks to Michal Chmielewski. wglass
Wrapped exceptions now have Cause property set on JDK 1.4. (note that Velocity continues to run under JDK 1.3). . Fixes VELOCITY-425. Thanks to Llewellyn Falco. wglass

Velocity now searches in the current thread's context classloader before the system classloader for all templates loaded with the ClasspathResourceLoader and for all user-defined ResourceLoaders, introspectors, event handlers, etc. A typical use for this is to have Velocity in the application container classpath while keeping templates and plugins in the webapp classpath. . Fixes VELOCITY-196. Thanks to . wglass
#set now sets references to null when required. For backwards compatibility this must be enabled by setting the configuration key <code>directive.set.null.allowed</code> to true. . Fixes . Thanks to Thomas Veith. wglass

Revert the split between org.apache.velocity.runtime.parser.node.Node and org.apache.velocity.runtime.parser.Node. The parser now only uses ...parser.node.Node because this change broke custom directives. . Fixes VELOCITY-426. Thanks to Malcom Edgar. henning
Made a lot of internal logging upgrades including: Deprecated LogSystem interface and replaced it (and all its implementations) with a new LogChute interface and implementations, added getLog() to RuntimeServices (and all its friends) to improve on and replace its now deprecated logging methods, added a JdkLogChute as a 3rd default option for those using JDK 1.4+, and added a StandardOutLogChute as final resort if other LogChute inits fail. See JIRA issues VELOCITY-403, VELOCITY-166, VELOCITY-403,VELOCITY-166,VELOCITY-78, VELOCITY-157, VELOCITY-159, VELOCITY-193. . Fixes VELOCITY-403. Thanks to . nbubna

Removed the long-deprecated Log4JLogSystem. Never fear, SimpleLog4JLogSystem remains. . Fixes . Thanks to . dlr
Enhanced the implementation of ResourceCacheImpl using Jakarta Commons Collections LRUMap class. The previous greedy implementation did not set an upper bound for the cache size, meaning that cached resources were never relinquished (a possible memory leak). You can continue to use that behavior by setting the <code>resource.manager.cache.size</code> for your cache to less than 1. . Fixes . Thanks to . dlr
Took dan's modified SimpleLog4jLogSystem, and renamed Log4JLogSystem, and put back old version of SimpleLog4JLogSystem, as deprecated. That way we can move forward with an up-to-date version that uses Logger, and for one release, be backwards compatile for the Category-using log4j crowd. . Fixes . Thanks to Daniel Rall. geirm
Deprecated class in favor of the various format classes in the Velocity Tools library. . Fixes . Thanks to . wglass
