I am trying to understand why this template evaluates to empty string on 1.7, and to "foobaryokdar" - on 1.5. String template = "#set($global_types=['foo', 'bar', 'yok', 'dar'])#macro( showBox $input)#set($type = \"\")$input#end"+ "#macro(showBoxes $types)#foreach($type in $types)#showBox($type)#end#end#showBoxes($global_types)"; </pre> Boris Partensky 2012-05-03T18:17:02 http://comments.gmane.org/gmane.comp.jakarta.velocity.user/15266 <pre>Hi, I have an oddball case where I need a multi-stage Velocity template evaluation. That is, image a pipelined process where: - Task one grabs a Velocity template, adds some (but not all) items to the Context, evaluates, and sends the partially resolved output as input to task two - Task two adds some (but not all) items to the Context, evaluates. I know I can have variables like ${object1.member1} that will be preserved in the output after evaluate() if object1 is not resolved, however, is it possible to maintain a foreach directive after an evaluation: ## preserve this 'foreach' in the output if object1 is not resolved #foreach( $element in $object1.elements ) #end Thanks in advance, John </pre> John McNair 2012-04-30T18:44:49 http://comments.gmane.org/gmane.comp.jakarta.velocity.user/15260 <pre>Hello, while going through the upgrade I noticed an incompatible behavior during nested macro evaluation. Looks like in 1.7 (all default properties) child macro has access to variables set in parent macro scope (and those take precedence over globals), and 1.5 sees globals. In the following example, in 1.5 unit test the following template will evaluate to "globalvar", and in 1.7 - to "outermacroparam". Is this expected behavior? 1.5 test case public void testVelocityNestedMacroScope() throws Exception { VelocityEngine ve = new VelocityEngine(); ve.init(); String template = "#macro(outerMacro $arg1)"+ "#innerMacro('blah')"+ "#end"+ "#macro(innerMacro $arg2)$arg1#end"+ "#set($arg1='globalval')#outerMacro('outermacroparam')"; StringWriter eval = new StringWriter(); boolean b = ve.evaluate(new VelocityContext(), eval, "foo", template); assertEquals(eval.toString(), "globalval", eval.toString()); } 1.7 test case public void testVelocityNestedMacroScope() { String template = "#macro(outerMacro $arg1)"+ "#innerMacro('blah')"+ "#end"+ "#macro(innerMacro $arg2)$arg1#end"+ "#set($arg1='globalvar')#outerMacro('outermacroparam')"; String eval = evaluate(template); assertEquals(eval, "outermacroparam", eval); } </pre> Boris Partensky 2012-04-30T15:49:39 http://comments.gmane.org/gmane.comp.jakarta.velocity.user/15256 <pre>All, I've been looking at the docs for both Velocity Tools and Velocity itself and I can't seem to find out what the properties are for controlling the number of template parsers to create and how big their buffer sizes are. I've been doing some memory profiling of my webapp and it looks like Velocity is keeping some rather large (and empty -- probably because they haven't yet been used) buffers for parsing. I can see a bunch (76) of int[4096] arrays within VelocityCharStream (the class member is 'bufline'), and I can also see buried in VelocityCharStream which uses an InputStreamReader ('inputStream') a byte[8192] which appears to exist 48 separate times. So, the total "wasted" space due to these two arrays (duplicated a bunch of times) is, on the face of it, small: it's like 1-2MiB. On the other hand, if I don't need all that buffer space, I'd like to remove it. So, first: how can I configure the number of parsers and possibly the buffer sizes used by them? Second: is VelocityCharStream essentially double-buffering since the InputStreamReader seems to have a large buffer inside it and also VelocityCharStream has its own buffer?

I feel that they are converted to List&lt;&gt; and then we cannot invoke methods with them as parameters. Let's take an example: #set($array = [$ref.getLong(), $ref.getLong(), $ref.getLong()] # where $ref.getLong() returns a long (primitive type) #ref.invokeSomeMethod($array) # where the signature is actually public void invokeSomeMethod(long[] values) How can I get this to work?

What is use of parenthesis in the #set directive: #set ($x = 1) Why not simply: #set $x = 1 ? Another question is regarding curly braces: What is the use of curly braces in the directives? E.g. #{set} ($x = 1) I am sure there are good reasons, just would like to know why. Thanks. </pre> Nikhil G. Daddikar 2012-03-26T07:36:09 http://comments.gmane.org/gmane.comp.jakarta.velocity.user/15234 <pre> Hi, I am having some issues with part of an expression that is not interpreted. Sorry if this is dumb question but I spent a couple of hours trying to solve this and could not (I am not very experienced in velocity) This template processes a response from apache solr search server. I have an almost exactly equal template running fine, and I looked at the differences and could not find any. Code looks like this: #if($params.getBool("debugQuery",false)) # toggle explain &lt;pre style="display:none"&gt;$response.getExplainMap().get($doc.getFirstValue('id'))&lt;/pre&gt; &lt;/pre&gt; # toggle all fields &lt;pre2 style="display:none"&gt; #foreach($fieldname in $doc.fieldNames) &lt;br&gt; $fieldname : #foreach($value in $doc.getFieldValues($fieldname)) $value #end #end &lt;/br&gt; &lt;/pre2&gt; #end The problem is '$response.getExplainMap().get($doc.getFirstValue('id'))' appears as is then the page, is not interpreted. response is the response from solr so has a bunch of info. If I leave only $response.getExplainMap() it works, a map struct is written. $doc.getFirstValue('id') is also interpreted fine (as 1, 2 etc). This exact code is working fine in another Solr project that has same velocity libs etc. Can anyone think of what is the issue? thanks </pre> jmlucjav 2012-03-22T08:26:48 http://comments.gmane.org/gmane.comp.jakarta.velocity.user/15232 <pre>Velosurf 2.3 has just been released. This release brings several new features, among which 'upsert' methods, per-field dirty flags, a cleaner syntax to specify external parameters for a query (aka 'parametrized getters'), some meta-information methods... It also provides several bugfixes and optimizations related to statements pools handling, database reverse enginering, connections checking and instance caching.

I'm writing a patch and I'd like to know if I need to stay away from anything too recent. It looks like we require Java 1.5+ in order to actually build Velocity Tools (generics, etc.), but I'm not sure about any runtime considerations. Thanks, -chris </pre> Christopher Schultz 2012-03-07T17:06:20 http://comments.gmane.org/gmane.comp.jakarta.velocity.user/15222 <pre>All, As an exercise, I decided to change my response content type from text/html to application/xhtml+xml as we are truly attempting to emit XHTML in all cases. I decided to see what Firefox would say if we did this. I found that any template that uses the validator tool to generate Javascript form validation ended up creating code like this: function validateMyForm(form) { if (bCancel) return true; else var formValidationResult; formValidationResult = validateInteger(form) &amp;&amp; validateRequired(form) &amp;&amp; validateMaxLength(form) &amp;&amp; validateMask(form) &amp;&amp; validateIntRange(form); return (formValidationResult == 1); } I have "xhtml" set to true in my (admittedly) old-style configuration: &lt;toolbox&gt; &lt;tool&gt; &lt;key&gt;validator&lt;/key&gt; &lt;scope&gt;request&lt;/scope&gt; &lt;class&gt;org.apache.velocity.tools.struts.ValidatorTool&lt;/class&gt; &lt;/tool&gt; ... &lt;xhtml&gt;true&lt;/xhtml&gt; &lt;/toolbox&gt; ...but the code still emits '&amp;&amp;' as the operator with no escaping. It appears that a trivial fix for this is to call setCdata(true) on the validator before generating the dynamic javascript, and then the whole thing gets put into a CDATA section, so the XML parser does not complain. On the other hand, I really don't want to have to edit all of my templates just to add 'setCdata(true)' to fix this. I'd rather have ValidatorTool know that when in XHTML mode, the "&amp;&amp;" needs to be "&amp;amp;&amp;amp;" instead. Is the intent that XHTML content should always use CDATA sections (in which case I should just suck it up and updated my templates), or should it be considered a bug that XHTML doesn't either automatically trigger the use of CDATA sections OR the generation of "&amp;amp;&amp;amp;" instead of "&amp;&amp;"?
