I have a line of Ruby-code with overloading methods. I want to show the call stack of the line.
I don't know the place for caller
or byebug
. I want to show the current call stack for the line after execution and find the place for debugging. How can I do it?
Approximately like caller Test.method
, and after that:
from /var/lib/gems/2.3.0/gems/railties-4.2.3/lib/rails/commands/console.rb:110:in `start'
from /var/lib/gems/2.3.0/gems/railties-4.2.3/lib/rails/commands/console.rb:9:in `start'
from /var/lib/gems/2.3.0/gems/railties-4.2.3/lib/rails/commands/commands_tasks.rb:68:in `console'
from /var/lib/gems/2.3.0/gems/railties-4.2.3/lib/rails/commands/commands_tasks.rb:39:in `run_command!'
from /var/lib/gems/2.3.0/gems/railties-4.2.3/lib/rails/commands.rb:17:in `<top (required)>'
It's not exactly like that, but it's very similar.
You can use method method
. For example
2.method(:hours)
=> #<Method: Fixnum(Numeric)#hours>
or probably more detail
2.method(:hours).source_location
=> ["~/.rvm/gems/ruby-2.3.3/gems/activesupport-4.2.7.1/lib/active_support/core_ext/numeric/time.rb", 29]
and after that you can use debuger(if posible) or go deeper
Another detail in this answer How to find where a method is defined at runtime?
