A = %q {def hello () "hello there!" end} thing.module eval (a) puts thing.new.hello () thing.module eval ("invalid code", "dummy", 123) and no need to use strings: module joi def happy?; true; end end class foo; end f1 = foo.new f2 = foo.new f2.class.class eval { include joi }.

How to create a class at runtime. i've been working on an application that has a number of forms that need to be laid out based on configuration data in the database. this enables the application to meet the requirements of many different customers. Hello, i need to add in runtime several methods to my class. how can i accomplish this in ruby? more precisely: i need my class to overload arithmetic operators with fixnums in both ways (4 myclass, myclass 4). all the necessary info is stored in a hash, so i created a method to do all the stuff. I have to add methods to class in execution time. the methods to add are declared in independent classes. def method one. end. def method two. end. i'm looking for an (elegant) mechanism to add all the extension class methods into the extendableclass. i'm thinking in explicily include the extension classes like:. At runtime, i would like to inject a line of code at the # < injection point class a def some method (a, b = 1, *c, d: 1, **e) # < injection point # code that does stuff.
