3.1 Basic Usage

The linker can be invoked on the input functor In in order to create an output functor Out as follows:

% ozl In -o Out

Consider for example the pickled functors A.ozf, B.ozf, and subdir/C.ozf, where A.ozf has been created from the following functor definition:

import B
       C at 'subdir/C.ozf' 

and the other functors have empty imports. By executing

% ozl A.ozf -o D.ozf

a new pickled functor D.ozf is created that contains both the functors contained in B.ozf and subdir/C.ozf but not the system functor Application.

If the linker is invoked in verbose mode as

% ozl --verbose A.ozf -o D.ozf


% ozl -v A.ozf -o D.ozf

for short, it prints the following information on which functors are in fact included and which are still imported by the newly created functor.

   A.ozf, B.ozf, subdir/C.ozf.

If we now invoke the linker on the newly created pickled functor D.ozf in verbose mode as follows:

% ozl -v D.ozf

it only prints the following information without creating a new functor:


By default, the linker includes (or links) all functors that are referred to by relative urls as in our previous example. How to change this behaviour is discussed in Section 3.2.
