Fri, 1 Jul 2022 18:09:05 +0200	Jan Dankert	New: Bugfixes and much more string and array functions for the DSL.
Sun, 26 Jun 2022 15:46:54 +0200	Jan Dankert	Fix: Another, little better, hack for parameterless functions. Shunting yard seems to be unable to handle empty parentheses.
Sun, 26 Jun 2022 12:51:07 +0200	Jan Dankert	New: DSL can be controlled by flags; support for error messages; support for negativ numbers.
Tue, 7 Jun 2022 23:30:20 +0200	Jan Dankert	New: DSL is now supporting throw statements.
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");
