simple expression language that doesn't use eval
thanks for the reply! im pretty new to this, so not really. you can take a peak at the source code (https://github.com/leongrdic/php-smplang/blob/master/src/SMPLang.php). it's pretty short and simple but I'd say parsing is pretty strict. I also think I've managed to make the exception message quite useful. let me know what you think if you manage to take a look!

okidoki - markdown editor with C# support
Yup it's in Blazor. For C# evaluation I've used ExpressionEvaluator. I'll probably replace it with Microsoft.CodeAnalysis.CSharp.Scripting library but I had some issues when i try to run it on WASM. I guess it's related to this issue
What are some alternatives?
