Today I am writing about ways to use <code>Pry</code>. <code>Pry</code> is <code>IRB</code> with incredible advantages. It let us research or investigate on the <code>objects and classes</code> we use. 
To start with <code>pry</code> we need to install it on our system.
<pre><code>gem install pry
gem install pry-doc
gem install pry-byebug
</code></pre>Now, simply open your terminal and write pry, you can directly start writing Ruby code inside it.
Eg:
<pre><code>[1] pry(main)&gt; 2 * 2 
=&gt; 25
[2] pry(main)&gt;
</code></pre>The most powerful pry command can be ls.

We can see a list of methods titled <code>String#methods</code>. We can see the hash(#) symbol which means that these are instance methods. These methods are only available to instances of the string class (object).
Pry Tricks and Tips
We can do something like this on <code>pry</code>
<pre><code>[1] pry(main)&gt; def hello
[1] pry(main)*
puts "Hello World"
[1] pry(main)* end
[2] pry(main)&gt;
[2] pry(main)&gt; edit -i 1
</code></pre>This will open the <code>hello</code> method inside the default editor (defined by $EDITOR environment variables) and allow us to edit it. Then pry run the code inside the pry session.
Some more useful pry commands:
<ul>
<li>find-method</li>
<li>watch</li>
<li>backtrace</li>
<li>cat</li>
<li>ri</li>
<li>@</li>
<li>history</li>
</ul>
we can also use <code>help</code> for looking other useful commands for Pry.

Today I am writing about ways to use `Pry`. `Pry` is `IRB` with incredible advantages. It let us research or investigate on the `objects and classes` we use. 

To start with `pry` we need to install it on our system.

```
gem install pry
gem install pry-doc
gem install pry-byebug
```

Now, simply open your terminal and write pry, you can directly start writing Ruby code inside it.
Eg:

```
[1] pry(main)> 2 * 2 
=> 25
[2] pry(main)>
```
The most powerful pry command can be **ls**.
