Ruby: Pretty-printed exception backtrace

pretty_backtrace.rb

# Generate a backtrace string for given exception.
# Generated string is a series of lines, each beginning with a tab and "at ".
def pretty_backtrace(exception)
  "\tat #{exception.backtrace.join("\n\tat ")}"
end

# Generate a string containing exception message followed by backtrace.
def pretty_exception(exception)
  "#{exception.message}\n#{pretty_backtrace(exception)}"
end

Example uses:

begin
  do_something
rescue => e
  STDERR.puts "Exception: #{e.message}"
  STDERR.puts "Backtrace:\n#{pretty_backtrace(e)}\n"
end

begin
  do_something
rescue => e
  STDERR.puts "Error: #{pretty_exception(e)}\n"
end
