eval

Maybe like: int a=1; int b=3; int c=Eval("a+b"); or int c=int.parse("1+3*(2+3)"); This seems stupid to me. is it possible in c#? You can take code, and using the CSharpCodeProvider write an Eval function that actually compiles your code into an in-memory assembly and then executes that code. See this CodeProject article for sample source. thinkbeforecoding Not directly. C# contains no runtime compiler. There is an open source project attached to Mono that will do this. I

My code to set a global variable using eval is not working. It's as if the assignment is not called at all, but no script errors occur. <script type="text/javascript"> $(function() { setTimeout(function() { eval('var x = 1;'); alert(x); }, 0); }); </script> <div onclick="alert(x);">Click to see 'x'</div> When the page loads, the alert shows what I expect; it confirms that x = 1. But after that, I click on the div and get a javascript error that x is undefined. How do I make eval add this variable properly? Background: The code above is a minimally reproducing example from a project I'm working

I'm trying to create a generic i18n solution for a HTML app I'm working in. I'm looking for alternatives to use eval() to call deeply nested Javascript objects: Suppose the following HTML example: <div id="page1"> <h1 data-i18n="html.pageOne.pageTitle"></h1> </div> and it's companion Javascript (using jQuery): var i18n; i18n = { html: { pageOne: { pageTitle: 'Lorem Ipsum!' } } }; $(document).ready(function () { $('[data-18n]').each(function () { var q; q = eval('i18n.' + $(this).attr('data-i18n')); if (q) { $(this).text(q); } }); }); Any advices on how to access the "pageTitle" property inside

If I understand correctly, to programmatically trigger a jQuery click event attached to an object with a css class of my-button , you should be able to just do this: $('.my-button').click(); For some reason, this code is failing to trigger the click event attached to the element. The $('.my-button') part of the code is working and returning one element. We know the event handler is attached to that element because clicking on the element does trigger its event handler's code. The handler is attached with the following simple code: $('<a class="my-button"/>') .click(function() { /* code here */

If a regular expression match occurs inside an eval, changes to the capture-related variables ($1, etc.) are not visible in the outside environment. Is this a bug? perlop and perlre don't seem to mention any such restriction. For example: use strict; use warnings; $_ = "hello"; eval '/(.*)/'; print "GOT: $1\n"; gives: Use of uninitialized value $1 in concatenation (.) or string at -e line 1. GOT: A more succinct demo is: perl -we '$_="foo"; eval q(/(.*)/;) ; print "GOT:$1\n";' Documentation proof that local ized variables are the issue here is in perlvar of 5.14.0 : These variables are read

Possible Duplicate: Is there something like Matlab's eval statement in Objective-C 2.0? Is there an eval function (as in lisp, javascript, python, ruby...) in Objective-C? What I mean by eval is a function that can take in arbitrary Objective-C code (possibly having class definitions, side effects, instrospection, etc) as a string (not a block or an NSInvocation or IMP or something like that), and evaluate each expression, respecting the current runtime environment state, side effects, class definitions, etc. If not, is it possible to implement within the confines of the existing runtime?

What is the best way to inject a snippet of code to scala? something like eval in javascript and GroovyScriptEngine. I want to keep my rules/computations/formulas outside the actual data processing class. I have close to 100+ formulas to be executed. The data flow is same for all only the formulas change. What is the best way to do it in scala? and the number of formulas will grow over time. You could use either scala-lang API for that or twitter-eval . Here is the snippet of a simple use case of scala-lang import scala.tools.nsc.Settings import scala.tools.nsc.interpreter.IMain object
