My new Ruby gems: string_in_file and array_in_file

I have published the Ruby gems string_in_file and array_in_file. Think of them as the ultimate global variables.

is used for storing a string in a file. In addition to writing a string value to a file and reading a string value from a file, you can also:

  1. Check to see if a particular string value is present in a file.
  2. Replace every instance of a given string in a file with another string.

array_in_file is used for storing an array of strings in a file, with each string separated by a newline character.

using string_in_file and array_in_file in my bsf_scrape and dvi_scrape gems, and I’m integrating them into my Bargain Stock Funds ( and Doppler Value Investing ( web sites as well. These gems are very simple, but they help me write cleaner code, as I don’t have to keep rewriting the functions for every Ruby gem or Rails app.
