evalSimple

public static IRubyObject evalSimple(ThreadContext context,
 RubyModule under,
 IRubyObject self,
 RubyString src,
 String file,
 int lineNumber,
 EvalType evalType)

Evaluate the given string.

Parameters:

context - the current thread's context

self - the self to evaluate under

src - The string containing the text to be evaluated

file - The filename to use when reporting errors during the evaluation

lineNumber - that the eval supposedly starts from

Returns:

An IRubyObject result from the evaluation

Evaluate the given string under the specified binding object. If the binding is not a Proc or Binding object (RubyProc or RubyBinding) throw an appropriate type error.

Parameters:

context - the thread context for the current thread

self - the self against which eval was called; used as self in the eval in 1.9 mode

src - The string containing the text to be evaluated

binding - The binding object under which to perform the evaluation

Returns:

An IRubyObject result from the evaluation
