ruby - What does *args mean? -


this question has answer here:

what args mean, , different between , argv if there difference?

 def puts_two(*args)     arg1, arg2 = args     puts "arg1: #{arg1}, arg2: #{arg2}"     end

argv special variable in ruby. contains arguments passed script on command line. example, if write following code in file called test.rb:

argv.each |a|     puts end

and call this

c:\> ruby test.rb 1 2

will display

one 2

in code posted, *args indicates method accepts variable number of arguments in array called args. have been called want (following ruby naming rules, of course).

so in case, args totally unrelated argv.

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
