It depends on your ruby. Ruby 1.8 includes your current path, while ruby 1.9 does not. Evaluate <code>$:</code> to determine if your path is included or not. So in ruby 1.9 you must use the entire path, which is always a safe bet.

Then you can use <code>require</code> or <code>load</code> to include the file.

<code>require</code> does not require you to add the suffix of the file when trying to find it and will only include the file once. <code>require</code> should be used instead of <code>load</code> most of the time.

If you only need to load one file into IRB you can invoke it with <code>irb -r ./your_file.rb</code> if it is in the same directory.

This automatically requires the file and allows you to work with it immediately.

Using ruby 1.9.3 on Ubuntu 14.04, I am able to load files from the current directory into <code>irb</code> with the following command line:

<pre><code>irb -I . -r foo.rb
</code></pre>

where <code>foo.rb</code> is the file I want to load from my current directory. The <code>-I</code> option is necessary to add the current directory (<code>.</code>) to ruby's load path, as explained in the ruby man page. This makes it possible to <code>require</code> files from the current directory, which is what the <code>-r</code> option to <code>irb</code> accomplishes.

The key piece that wasn't obvious for me when I had this problem is the <code>-I</code> option. Once you do that, you can call <code>require 'foo.rb'</code> from within <code>irb</code> for any files in the current directory. And of course, you can specify any directory you want, not just <code>.</code> with the <code>-I</code> option. To include multiple directories on the load path, separate them with a colon (:), e.g.:

<pre><code>irb -I foo/:bar/:baz/
</code></pre>

This command will add the directories <code>foo</code>, <code>bar</code>, and <code>baz</code> to ruby's load path.

The final alternative is to use the relative or absolute path to the file when using <code>require</code> or <code>-r</code> to load a file:

<pre><code>irb -r ./foo.rb
</code></pre>

or from within <code>irb</code>:

<pre><code>&gt; require './foo.rb'
</code></pre>

blocks|key|230149|text|将路径加载到irb的另一种方法是键入require，然后将文件拖放到终端中。使用Linux+Mint的-tested。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|230150|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Another way to load the path into irb is just type require then drag and drop the file into the terminal.

blocks|key|230179|text|对于那些想要从不同目录加载.rb文件的人。只需将目录的字符串表示符添加到$：variable。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|230180|>+$:+<<+"/directory/to/the/required/rb/file"

For those, who want to load .rb file from the different directory. Just add a string representer of the directory to $: variable.

&gt; require "some_file"
