Callstack¶ ↑

Callstack is a simple gem that bundles a C extension to provide better stack traces on Ruby 1.8. Based on: eigenclass.org/hiki.rb?ruby+backtrace+data

sudo gem install callstack

• Ruby 1.8

• C compiler

To get the call stack trace, simply require use the callstack method, as such:

require 'rubygems'
require 'callstack'

def foo; bar end
def bar; p callstack end

class Moo
  def initialize
    foo
  end
end

Moo.new

This will output the following stack:

[[Object, :bar, "example.rb", 5], [Object, :foo, "example.rb", 4], [Moo, :initialize, "example.rb", 9], [nil, nil, "example.rb", 13]]

The callstack method also accepts an optional integer argument that specifies the desired depth of the stack call trace. Using +callstack(2)+ on the previous example would output:

[[Object, :bar, "example.rb", 5], [Object, :foo, "example.rb", 4]]
