Nested Directives with Parameters

by

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 that some concepts have been implemented late or completely reworked. Some concepts are still awaiting implementation. One of these concepts is the parameters of the nested directive, which will be implemented for FreshMarker 2.7.0.

Vier Jahre FreshMarker

by

Vor vier Jahren begann das Abenteuer FreshMarker mit dem Blog-Beitrag „FreshMarker, eine frische Template Engine für Java“. Was als akademisches Experiment startete, hat sich inzwischen zu einer vielseitigen und stabilen Template Engine entwickelt. Mit Version 2.5.0 und insgesamt 87 Blog-Beiträgen, die verschiedenste Aspekte beleuchten, ist nun der richtige Zeitpunkt für ein Resümee.

Diagram As Code

I recently sat in a lecture about PlantUML and the advantages of Diagram As Code. Diagram As Code is a special variant of Documentation As Code. It is the possibility for software developers to create their documentation in the form of text files without the use of word processing systems. The advantage is obvious, the developer can use his documentation like his source code. Versioning, automatically creating comparisons, transforming, validating and much more. This gave me the idea of developing something similar.

In Search Of Performance (2)

by

This article on performance was not actually intended to be a multi-part article. But if you take a closer look at your own code through performance glasses, you will quickly discover further bottlenecks. In this case, it’s an unclean modeling that FreshMarker has been carrying around since its early days. This article is about how this affects the performance of the template engine.

Bullseye Architecture

by

I call Hexagonal Architecture, Onion Skin Model and Clean Architecture the “Bullseye Architectures”, because they contain the domain logic as a central component in the middle of their structure.Currently they are popular again, so here is a short article on the topic.

In Search Of Performance

by

In addition to the expressiveness of the template, the number of supported data types and functions and the expandability, performance is a decisive criterion for a template engine. FreshMarker only evaluates the template output at runtime, so although the template engine is very flexible, it cannot compete with those that evaluate the templates at compile time. For historical reasons, FreshMarker also has no upfront type information about the data used, so some optimization options are not available.

A Custom Forth Interpreter

Once again there was an funny code challenge from John Crickett. This time a custom Forth interpreter was to be implemented. Forth is a very interesting language that I got to know in my youth. Unfortunately, I don’t remember exactly, but I probably tried it out on my Commodore 128D at some point.
