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

Checksums with FreshMarker File
Some time ago, I had the idea that a checksum calculation could be added to the FreshMarker File library. FreshMarker File is an extension for FreshMarker to support the Java types File and Path. A checksum support would allow the current checksum to be added to lists of files without any major det

Context-Sensitive Tokenization With CongoCC
If you want to interpret a programming language or a DSL, there's no way around using a parser generator. At the heart of FreshMarker is a template parser generated by the CongoCC parser generator. I can't praise this JavaCC successor from Jon Revusky highly enough. Many new features and completely revised parts m

Quo Vadis, Lambda?
To implement a new built-in for sequences, lambdas were added as a new language component of the FreshMarker Expression Language. The lambda expression made it much easier to map the semantics of the new count built-in in an easily readable syntax. Now that lambda expressions are available, what else can they be used for and what s

An important component of the FreshMarker template engine is the built-in expression language. The expression language is used to utilize not only variables but also complex expressions in directives and interpolations. When evaluating other expression languages for customer projects, somet
