Sat, 28 May 2022 18:00:13 +0200	Jan Dankert	New: DSL with a much better syntax parsing and support for assignments, conditions, ...
Wed, 25 May 2022 22:47:17 +0200	Jan Dankert	New: DSL (domain specific language) for code elements. The old way with PHP code ist not sandboxed and unsecure. This approach is a minimalistic, javascript-like, scripting engine. For now only simple function calls are possible, for example: alert("example");
