https://bugzilla.novell.com/show_bug.cgi?id=675755#c0 Summary: Enable explicitly typed expression evaluation in the C# Evaluator Classification: Mono Product: Mono: Compilers Version: 2.8.x Platform: Other OS/Version: Other Status: NEW Severity: Enhancement Priority: P5 - None Component: C# AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.21 (KHTML, like Gecko) Ubuntu/10.04 Chromium/11.0.677.0 Chrome/11.0.677.0 Safari/534.21 Allow generic type parameters for the `Evaluator.Compile()` and `Evaluator.Evaluate()` methods to allow more flexible input expressions, e.g. lambda's. Consider the following use case: var code = "x => x * x" // can be from any input; var lambda = Evaluator.Evaluate<Func<float, float>>(lambda); Plot(lambda); Currently this has to be done using: var lambda = (Func<float, float>)Evaluator.Evaluate("Func<float, float> f = " + lambda + "; f;"); This is unwanted for at least two reasons: - Extra variable introduced, this could infer with the input. - The expression (here `code`) must be rhs valid; This feature would consist of the addition of the following four methods and one delegate: public static T Evaluate<T>(string input); public static string Evaluate<T>(string input, out T result, bool result_set); public static CompiledMethod<T> Compile<T>(string input); public static string Compile<T>(string input, out CompiledMethod<T> compiled); public sealed delegate void CompiledMethod<T>(ref T retvalue); Reproducible: Always -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
