Customizing Parser

Flee allows customization of its expression parser. Customizing the parser is done through the ExpressionContext.ParserOptions property. You set the properties to the values you want and then call RecreateParser to apply your changes.

Here's an example:

ExpressionContext context = new ExpressionContext();
context.Imports.AddType(typeof(Math))

context.CompileDynamic("max(1.23, 4.56)", context);

context.ParserOptions.DecimalSeparator = ',';
context.ParserOptions.FunctionArgumentSeparator = ';';
context.RecreateParser();

context.CompileDynamic("max(1,23; 4,56)", context);
