# Ride: Tokenizer Library
This library gives you some classes to parse a string into tokens.
## Code Sample
Some example code in the context of the ORM module:
```php
setWillTrimTokens(true);
$tokenizer->addSymbol(new SimpleSymbol('AND'));
$tokenizer->addSymbol(new SimpleSymbol('OR'));
$tokenizer->addSymbol(new NestedSymbol('(', ')', $tokenizer));
$condition = '{field} = %2% AND {field2} <= %1%';
$tokens = $tokenizer->tokenize($condition);
// array(
// '{field} = %2%',
// 'AND',
// '{field2} <= %1%'
// )
$condition = '{field} = 5 AND ({field2} <= %1% OR {field2} >= %2%)';
$tokens = $tokenizer->tokenize($condition);
// array(
// '{field} = 5',
// 'AND',
// array(
// '{field2} <= %1%'),
// 'OR',
// '{field2} >= %2%'),
// )
// )
```
