# hooks

This folder contains a very simple example of using the Logtalk compiler 
hook support to (1) expand abbreviations in `info/1` directives; (2) convert
`write/1` goals into `write_term/3` goals where the terms written are quoted
and pre-processed by using `numbervars/3`.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

```logtalk
%versions
```

Start by loading the example:

```logtalk
logtalk_load(hooks(loader)).
```

Check the XML documenting file generated for `object` for the results of the
`term_expansion/2` calls.

Check the results of the `goal_expansion/2` calls:

```logtalk
object::out.
```
