[jruby-dev] [jira] (JRUBY-6760) ArgumentError output

[Benoit Daloze (JIRA)]

Benoit Daloze created JRUBY-6760 ArgumentError output Issue Type: Bug Affects Versions: JRuby 1.7.0.pre1 Assignee: Thomas E Enebo Created: 03/Jul/12 4:50 PM Description: Given a file `args_error.rb` with def my_meth(a) end my_meth 1, 2 In JRuby, this produces: ArgumentError: wrong number of arguments (2 for 1) (root) at args_error.rb:4 In MRI 1.9: args_error.rb:1:in `my_meth': wrong number of arguments (2 for 1) (ArgumentError) from args_error.rb:4:in `<main>' In MRI 1.8.7: args_error.rb:4:in `my_meth': wrong number of arguments (2 for 1) (ArgumentError) from args_error.rb:4 (Only the line number change) The MRI version (and Rbx too by the way) mentions the method name. I think this can be helpful, to easily understand what might be the problem without needing to go to the caller place, and when the call is dynamic (#send). For the location, 1.8 seems to mention the caller location, while 1.9 shows the callee location (and likely showing the line of the method definition in its file, which can be very helpful).
