+If you are a ruby user and find it annoying to remove [binding.pry](http://pryrepl.org/) by hand, you may
+find the following snippet useful. (Put it in your ~/.pryrc to use it)
+
+```ruby .pryrc
+Pry.config.commands.command "remove-pry", "Remove current pry" do
+  require 'pry/commands/edit/file_and_line_locator'
+  file_name, remove_line =
+Pry::Command::Edit::FileAndLineLocator.from_binding(_pry_.current_binding)
+  temp_file = Tempfile.new('foo')
+  i = 0
+  File.foreach(file_name) do |line|
+    i += 1
+    if i == remove_line
+      line.gsub!(/binding.pry(\s)?/, "")
+      temp_file.write line unless line =~ /\A[[:space:]]*\z/
+    else
+      temp_file.write line
+    end
+  end
+  temp_file.close
+  FileUtils.cp(temp_file.path, file_name)
+end
+```
+
+**Usage**
+
+Before:
+```ruby debug.rb
+# ...
+if foo == :bar
+  binding.pry
+  a_shiny_method
+end
+# ...
+```
+
+```ruby in pry
+pry> remove-pry
+```
+
+After:
+```ruby debug.rb
+# ...
+if foo == :bar
+  a_shiny_method
+end
+# ...
+```
