# Ruby Associated Tools

# Standard Ruby Tools:

The standard Ruby distribution contains useful tools along with the interpreter and standard libraries:

These tools help you debug and improve your Ruby programs without spending much effort. This tutorial will give you a very good start with these tools.

- RubyGems :
  RubyGems is a package utility for Ruby which installs Ruby software packages, and keeps them up to date.

- Ruby Debugger :
  To help deal with bugs, the standard distribution of Ruby includes a debugger. This is very similar to gdb utility which can be used to debug complex programs.

- Interactive Ruby (irb) :
  irb (Interactive Ruby) was developed by Keiju Ishitsuka. It allows you to enter commands at the prompt and have the interpreter respond as if you were executing a program. irb is useful to experiment with or to explore Ruby.

- Ruby Profiler :
  Ruby profiler helps you to improve the performance of a slow program by finding the bottleneck.

# Additional Ruby Tools:

There are other useful tools that don't come bundled with the Ruby standard distribution. However, you do need to install them yourself.

- eRuby: Embeded Ruby :
  eRuby stands for embedded Ruby. It's a tool that embeds fragments of Ruby code in other files such as HTML files similar to ASP, JSP and PHP.

- ri: Ruby Interactive Reference :
  When you have a question about the behavior of a certain method, you can invoke ri to read the brief explanation of the method.
