Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(meth, *args) ⇒ Object

We pass any missing methods on to the Pasteboard.

Instance Attribute Details

#on_paste(&block) ⇒ Object

Acts as both a getter and a setter for the @on_paste attribute. If passed a block, it sets that block as the @on_paste hook - else it returns the current hook block.

Class Method Details

.find(name) ⇒ Object

This checks the Jello require paths for a mould by that name. The following directories are checked, in this order:

- `$HOME/.jello/*.rb`
- `/etc/jello/*.rb`
- `$JELLO_SRC/moulds/*.rb`

The first one with a file by the correct name will overide any later ones.
