|`uuid(kind)` | `String` | Returns a UUID using the Camel `UuidGenerator`. You
can choose kind between `default`, `classic`, `short`, `simple` and `random` as
the kind. If no kind is given, then `default` is used. It is also possible to
use a custom `UuidGenerator` and bind the bean to the
xref:manual::registry.adoc[Registry] with an id. For example
`${uuid(myGenerator)}` where the id is `myGenerator`.

+To use OS environment variables you use the `${env.key}` function, such as
`${env.PATH}` or `${env.HOME}`, or `${env.JAVA_HOME}`.
+Notice how the key should be in uppercase, as required by OS environment
variables.
+
+The `hash` function is used for calculating a hash value of the given value.
The `${hash()}` would use the message body and SHA-256 as algorithm and
+return a hash value as String hex-decimal.
+
+The `hostname` function returns the OS hostname and does not require using
parenthesis, so just use `$\{hostname}`.
+
+The `null` function returns a `null` value such as `$\{null}`.
+
+To use JVM system properties you use the `${sysenv.key}` function, such as
`${sysenv.java.version}` or `${sysenv.java.io.tmpdir}`.
+
+You can get the current thread id by the `$\{threadId}` function, and the name
via `$\{threadName}`.

+And you can generate unique IDs with the xref:manual::uuidgenerator.adoc[Camel
UUID Generator] by the `uuid` function.
+The generator supports different kinds `default`, `classic`, `short`, `simple`
and `random`, such as `${uuid(random)}`.

The simple language has limited support for operators that are used in
predicates to evaluate whether a condition is either _true_ or _false_.
