# trycatch

This is a simple Puppet module that adds the functions `try` and `catch`.

They can be used to catch an exception raised in the block passed to `try`.

This module uses the V4 function API, so you need Puppet 4.x to use it or

Puppet 3.7.x with the future parser.

## Example

```puppet

$ret = try() || {

  assert_type('String', 1)

  notice('This code is never reached')

  'return value from try'

}.catch |$exception| {

  notice($exception['class'])

  notice($exception['message'])

  'return value from catch'

}

notice($ret)

```

Output:

```

Notice: Scope(Class[main]): Puppet::PreformattedError

Notice: Scope(Class[main]): Evaluation Error: Error while evaluating a Function Call, assert_type(): Expected type String does not match actual: Integer at /Users/dalen/src/puppet-trycatch/test.pp:2:3

Notice: Scope(Class[main]): return value from catch

Notice: Compiled catalog for river.local in environment production in 0.28 seconds

Notice: Applied catalog in 0.01 seconds

```

### Only catch certain exceptions

```

try() || {

  assert_type('String', 1)

}.catch('ArgumentError', 'RuntimeError') |$exception| {

  notice("Caught ${$exception['class']}")

}

```

Output:

```

Error: Evaluation Error: Error while evaluating a Function Call, assert_type(): Expected type String does not match actual: Integer at /Users/dalen/src/puppet-trycatch/test.pp:2:3 on node river.local

```

Note that this doesn't take exception subclasses into account. It only checks

if the class names match exactly.

## Note that this is a hack, use accordingly
