The libraries are divided into several packages. The available packages are:
This package contains the Prelude and its support libraries, and a large
collection of useful libraries ranging from data structures to parsing
combinators and debugging utilities.
- Most of the time, all the packages are available without the need to
use any additional command-line options. The only time when this is not the
case is when linking a program on the command line, without using the --make
option: in this case you must list all the packages to link to by adding the
-package P flag (where P is the package name) to the command line for each
package. See the User's Guide (../users_guide/index.html) for more
- Hugs provides almost all of the modules in the above packages,
with exceptions listed on the Hugs 98 libraries status page
All those modules are always available.
- Nhc98 provides many of the modules in the above packages (see the
Nhc98 libraries page (http://www.haskell.org/nhc98/libraries.html) for a more
details). The modules of the haskell98 package are available without the need
to use any additional compile-time options. To use modules from some other
package P with Nhc98, add the compile-time option -package P.
