Exception: Exception

Defined in:
lib/rmtools/dev/trace_format.rb

Overview

Usage with Rails. Rails raise and rescue a bunch of exceptions during a first load, a reload of code (e.g. in development env) and maybe even some exceptions for each request. Thus, trace_format should be set only in a console environment after a code is loaded. For a web-server environment use RMTools.format_trace for inspect backtrace after an exception was rescued. Also note that Rails’ autoreload of code won’t rewrite SCRIPT_LINES__.

#set_backtrace(src) ⇒ Object

If you also set (e.g. in irbrc file)

module Readline
  alias :orig_readline :readline
  def readline(*args)
    ln = orig_readline(*args)
    SCRIPT_LINES__['(irb)'] << "#{ln}\n"
    ln
  end
end

it will be possible to fetch lines entered in IRB else format_trace would only read ordinally require’d files
