FreshMarker 1.11.0
I am pleased to announce the release of the Java 21 template engine FreshMarker 1.11.0. This is the last planned release before the next major release 2.0.0 and includes some new features and improvements.
FreshMarker Fo(u)r Seasons
Some features in open source projects are gimmicks whose utility value is rather low. On the other hand, they enable the evaluation of new functions and previously unused libraries. In this article, support for astronomical seasons is implemented in Freshmarker using the Time4J library.
Optimize Switch for Constants
The FreshMarker Switch Directive is an unusual representative of its kind. Since it has been implemented according to the possibilities of its syntax description in the CongoCC example source code, it is capable of quite unusual working methods. Some special cases could be processed faster with an optimized version. Therefore, the Switch Directive is optimized for constants in this article.
REST endpoints with filters
This article is a slightly updated English version of the article “REST Endpunkte mit Filtern”.
In addition to sorting and pagination, filtering is a fairly common action on REST endpoints. In contrast to the first two, however, there is no adequate solution for filtering in the Spring Boot framework. With little effort, however, this can be elegantly implemented with the Spring Boot tools.
Of bridges and tunnels – agile system creation
Tunnel constructions are classic waterfall projects in which extensive planning is carried out and then construction can be completed without major changes. There are geological surprises from time to time, but a tunnel plan is, quite literally, set in stone.
Optimistic Locking mit dem ETag Header
Wenn mehr als ein Beteiligter beim Speichern von Daten involviert ist, kann es zu ungewollten Überschreibungen kommen. Um solche Probleme zu umgehen, existieren drei Vorgehensweisen. Pessimistic Locking, Optimistic Locking und Ignore It!
FreshMarker 1.10.0
I am pleased to announce the release of the Java 21 template engine FreshMarker 1.10.0. The version includes some new features and improvements.
List Directive Unrolled
The Partial Template Reduction feature allows FreshMarker templates to be simplified. Part of the model is used to evaluate expressions in directives and interpolations and generate a new template. A template reduced in this way contains fewer dynamic and more static parts and can therefore be evaluated more quickly. Until now, list directives were excluded from the simplification options. This can now change under certain circumstances.
FreshMarker Variable Scope Revised
The blog posts on the FreshMarker template engine pursue several goals. On the one hand, the posts should of course entertain their readers. On the other hand, they also serve me to focus and document my ideas on various aspects of the implementation. One very interesting topic in this post is the management of variables within the Template Engine.
FreshMarker 1.9.0 available
I am pleased to announce the release of FreshMarker 1.9.0. The version includes some new features and improvements. The library is now available on Maven Central. And for all those who like a cheat sheet, there is now one available here.
Masking Sensitive Information in FreshMarker
Working as a software developer allows me to constantly look into new subject areas and gather inspiration for my projects. Looking at a document with redacted information was the impetus for two new FreshMarker built-ins mask and mask_full.
Padding in FreshMarker
A wonderful achievement of agile software development is, that new features are implemented when they are needed and not before. It took a long time for the built-ins left_pad and right_pad for padding text to be implemented, but now they are finally here.
Checking Types with Build-Ins in FreshMarker
The FreshMarker Template Engine works with an interpolation system that only takes the type of a variable into account at evaluation time. This approach makes the use of variables in FreshMarker very flexible, but occasionally leads to runtime errors. These can be avoided if the type of a variable can be checked beforehand.
