Ruby how to reset class methods -

-

using module_eval, code allows me dynamically create , add new methods class based on input parameters. see post example ruby class_eval , yield

now question how reset class original methods? there simple method can use reset class it's original state? reason once new methods added class, persists , need rid of them if create new object different set of methods.

also must apologize if question doesn't quite make sense, i've been 24 hours , needed rest think clearly. if not clear, can provide example. in advance.

edit: added complete solution

if keep list of methods added in earlier post, can use remove_method remove these methods like:

class mytest   @@methods_list = []    def self.show_methods     @@methods_list   end    def self.reset_methods     @@methods_list.each |method|       remove_method(method)     end     @@methods_list = []   end    def self.add_methods     define_method("method1")  { puts "this method1" }     define_method("method2")  { puts "this method2" }     true   end    def self.method_added(method_name)     @@methods_list << method_name.to_s     puts "added: " + method_name.to_s + ", list: " + @@methods_list.inspect   end end

now can try out following:

>> require 'mytest.rb' >> t = mytest.new # => #<mytest:0x2b1e293247f0> >> mytest.add_methods added: method1, list: ["method1"] added: method2, list: ["method1", "method2"] >> t.method1 # method available: method1 >> mytest.reset_methods >> t.method1 # method undefined now, we'd expect error nomethoderror: undefined method `method1' #<mytest:0x2b1e293247f0>     (irb):6

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() .

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
