# Customization
You can customize the way that data is stored. For example, you might want to add a constant property to each pattern.
To do this, you provide a custom function when you create the _patrun_ object:
```JavaScript
var alwaysAddFoo = patrun( function(pat){
pat.foo = true
})
alwaysAddFoo.add( {a:1}, "bar" )
alwaysAddFoo.find( {a:1} ) // nothing!
alwaysAddFoo.find( {a:1,foo:true} ) // == "bar"
```
Your custom function can also return a modifer function for found
data, and optionally a modifier for removing data.
Here's a example that modifies found data:
```JavaScript
var upperify = patrun( function(pat){
return function(args,data) {
return (''+data).toUpperCase()
}
})
upperify.add( {a:1}, "bar" )
upperify.find( {a:1} ) // BAR
```
Finally, here's an example that allows you to add multiple matches for a given pattern:
```JavaScript
var many = patrun( function(pat,data){
var items = this.find(pat,true) || []
items.push(data)
return {
find: function(args,data){
return 0 < items.length ? items : null
},
remove: function(args,data){
items.pop()
return 0 == items.length;
}
}
})
many.add( {a:1}, 'A' )
many.add( {a:1}, 'B' )
many.add( {b:1}, 'C' )
many.find( {a:1} ) // [ 'A', 'B' ]
many.find( {b:1} ) // [ 'C' ]
many.remove( {a:1} )
many.find( {a:1} ) // [ 'A' ]
many.remove( {b:1} )
many.find( {b:1} ) // null
```
