directory - Get path of parent requiring file, Ruby -

-

Is it possible to get the location of the file, for which another file is required in Ruby?

I have a project where I used to create some processes and I would love to be able to code to make sure which file is the parent of the required file, it is good when debugging .

Example: 

  # initial.rb: "./my_file.rb" is required "fork" / my_file2.rb "end  < / Pre> 
 -  
  # my_file.rb: puts "required from file: # {?????}"   
 -  
  # my_file2.rb: Required "./my_file.rb"   
 I hope to do something like this:  
 Required from file  # = & gt; /path/to/initial.rb # = & gt; Required from file: /path/to/my_file2.rb    
 
 
 Based on the end I need  need_relative  and  to   < Red>  | "\ t # {x}"} "% s requires% s "% [Caller.first.split (/: \ d + /, 2). First, arg] Old_require_related Arg end alias: old_require: def requirement (arg) # ~ collar.map {| x |" \ t # X} "}"% s requires% s "% [caller.first.split (/: \ d + /, 2). First, arg] old_require arg end   
 In a test test scenario with the following load sequence:  
  test.rb + - test1.rb + - test1_a.rb + test2.rb   
 Call  
  is required './test1' is required './test2' '  
 or  
  Required_related 'test1' needs_r Results in elative 'test2' '  
:  
  test.rb is required ./test1 C: /Temp/test1.rb test1_a test.rb Required is required ./test2   
 You can also include the required line in the output.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...
