Library overview
Haskell 1.4 places much greater emphasis on the use
of libraries than previous versions of
the language. Following that lead, the Hugs 1.4
distribution includes most of the official libraries defined in the
Haskell Library Report [2].
The distribution also includes a number of unofficial libraries, which
fall into two categories: portable libraries, which are implemented using
standard Haskell or widely implemented Haskell extensions; and Hugs-specific
libraries, which use features that are not available in other Haskell
implementations.
All that you need to do to use libraries is to import them
using an import declaration.
For example:
module MandlebrotSet where
import Array
import Complex
...
Of course, this assumes
that HUGSPATH has
been set to point to the directories where the libraries are
stored, and
that import chasing is enabled.
The default search path includes the
directories containing both the standard and unofficial libraries.
