Relative Path in ruby - for File open

[Shekar Ls]

Hi Guys,
I am trying to fetch a file to do some processing in ruby,
instead of giving the absolute path i wanted to give relative path.

File.open("config.txt") do |source|
source.each_line do |line|
if line =~ /^(\w+)\s*=\s*"(.*)"\s*$/
....

In the above mentioned example, i want config.txt to be accessed from
the current path whichever user runs it.

Cheers

By "current path" do you mean executable path or the current working
directory of the script?

If you mean the current working directory (i.e. ENV['PWD']) everything
should work as you expect. Just do File.open("config.txt")

And if you mean the directory in which the script is located, then

AppRoot = File.expand_path(File.dirname(__FILE__))

File.open(File.join(AppRoot, "config.txt")) do |source|
..
end
