### Run Irb

Use the ```run_irb``` feature to execute selected Ruby snippets in the Ruby interactive shell, ```irb```.

This allows you to interleave *any* markdown (usually explanatory text, but actually anything) with the Ruby snippets.

In the example template below, snippets of Ruby are interleaved with other markdown elements.

Each Ruby snippet that's to be executed in ```irb``` is bracketed by pragmas <code>\`\`\`#run_irb</code> and <code>\`\`\`</code>.

In the example, each snippet has some Ruby code that shows values using method ```p```.

@[:pre](template.md)

@[:markdown](../interface.md)

The resulting markdown (raw) shows the output from ```irb``` for each snippet:

@[:pre](markdown.md)

Resulting markdown (rendered):

---

@[:markdown](markdown.md)
