Haskell Hierarchical Libraries
The libraries are divided into several packages.
NOTE: there is not always a clean division between packages in the
hierarchy, which means a node and its children might be in
different packages. If you're looking for a specific module, try
all the packages below.
the Prelude, and a large collection of useful libraries.
Haskell 98 and FFI Standard Libraries.
networking support libraries.
manipulating Haskell source code.
a library for interactively reading input from the console.
supplies POSIX functionality (not all platforms).
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
for more details.
- Hugs 98
Hugs provides almost all of the modules in the base package,
all the modules in the
haskell98, network and haskell-src packages,
and some of those in the unix package.
These modules are always available, as a single hierarchy;
Hugs does not use the package subdivision.
To use modules from a package P with Nhc98,
add the compile-time option -package P.
Nhc98 currently provides many of the modules in the
base package (see the
Nhc98 libraries page
for a list).
