The PooledTemplateProcessor
Memory management is a major challenge when it comes to improving the performance of Java applications. When many objects are created, memory must be allocated for them; these objects must be managed and eventually deleted, and their memory released. This comes at a cost, and an application that consistently works with fresh obj

FreshMarker 2.7.0 – New Release!
After two months of development, I’m pleased to announce the release of FreshMarker version 2.7.0. This time, the focus was on functional hash processing, more flexible formatting, and a major step toward a more consistent template syntax. Overall, it’s a well-rounded mix of new expression capabilities and impr

The End of Loose Tag End
While designing a new feature, I once again stumbled upon a feature of the template language that I haven’t liked for a long time. The syntax of the directives is modeled after HTML elements, not XML elements. As long as you don’t want to change the syntax of the template language, this isn’t a problem. But if you

Partial Reduction of Range Lists
One of the most useful optimizations in FreshMarker is partial reduction: templates can be partially evaluated in advance if part of the model is already known. Until now, however, partial reduction had a blind spot—List directives with ranges (1..4, 4..1, 1..) were ignored during reduction and passed throug

Enum Hashes (2)
In the FreshMarker template engine, hashes are a central data structure. Hashes access data via a name. Up until version 2.6.0, FreshMarker only supported hashes that used strings as names. Hashes that allow enums as names now exist, but their integration is far from complete.

Nested Directives with Parameters
When replicating the concepts of another template engine, there are always moments when you put off working on a particular concept. This rarely has anything to do with the complexity of the concept itself, but often stems from a personal aversion. For FreshMarker, this has meant tha

The General Concatenation Operator
The FreshMarker Template Language provides two operators for concatenating string values: the string concatenation operators + and ~. Both operators produce a string from their two operands. The difference between the two operators lies in the way the strings are joined together. The unique feature of the ~ operato

Enum Hashes
FreshMarker is based on the concepts of another template engine. This is evident from its directives, interpolations, and, of course, its name. Another detail also betrays its origins. The types in the FreshMarker Template Language for collections are sequences and hashes. Hashes represent mappings from strings to values. We now want to rel
