The cabal-install package

[Tags:bsd3, program, test]

The 'cabal' command-line program simplifies the process of managing Haskell software by automating the fetching, configuration, compilation and installation of Haskell libraries and programs.

The cabal-install package

[Cabal home page](

The `cabal-install` package provides a command line tool called `cabal`. The
tool uses the `Cabal` library and provides a convenient user interface to the
Cabal/Hackage package build and distribution system. It can build and install
both local and remote packages, including dependencies.

Installation instructions for the cabal-install command line tool

The `cabal-install` package requires a number of other packages, most of which
come with a standard ghc installation. It requires the `network` package, which
is sometimes packaged separately by Linux distributions, for example on
debian or ubuntu it is in "libghc6-network-dev".

It requires a few other Haskell packages that are not always installed.
The exact list is specified in the `.cabal` file or in the ``
file. All these packages are available from

Note that on some Unix systems you may need to install an additional zlib
development package using your system package manager, for example on
debian or ubuntu it is in "zlib1g-dev". It is needed is because the
Haskell zlib package uses the system zlib C library and header files.

The `cabal-install` package is now part of the Haskell Platform so you do not
usually need to install it separately. However if you are starting from a
minimal ghc installation then you need to install `cabal-install` manually.
Since it is just an ordinary Cabal package it can be built in the standard
way, but to make it a bit easier we have partly automated the process:

Quickstart on Unix systems

As a convenience for users on Unix systems there is a `` script
which will download and install each of the dependencies in turn.

    $ ./

It will download and install the dependencies. The script will
install the library packages into `$HOME/.cabal/` and the `cabal` program will
be installed into `$HOME/.cabal/bin/`.

You then have two choices:

 * put `$HOME/.cabal/bin` on your `$PATH`
 * move the `cabal` program somewhere that is on your `$PATH`

The next thing to do is to get the latest list of packages with:

    $ cabal update

This will also create a default config file (if it does not already echo exist)
at `$HOME/.cabal/config`

By default cabal will install programs to `$HOME/.cabal/bin`. If you do not
want to add this directory to your `$PATH` then you can change the setting in
the config file, for example you could use:

    symlink-bindir: $HOME/bin

Quickstart on Windows systems

For Windows users we provide a pre-compiled [cabal.exe] program. Just download
it and put it somewhere on your `%PATH%`, for example
`C:\Program Files\Haskell\bin`.


The next thing to do is to get the latest list of packages with

    cabal update

This will also create a default config file (if it does not already echo exist)
at `C:\Documents and Settings\username\Application Data\cabal\config`

Using cabal-install

There are two sets of commands: commands for working with a local project build
tree and ones for working with distributed released packages from hackage.

For a list of the full set of commands and the flags for each command see

    $ cabal --help

Commands for developers for local build trees

The commands for local project build trees are almost exactly the same as the
`runghc Setup` command line interface that many people are already familiar
with. In particular there are the commands

    cabal configure
    cabal build
    cabal haddock
    cabal clean
    cabal sdist

The `install` command is somewhat different. It is an all-in-one operation. If
you run

    $ cabal install

in your build tree it will configure, build and install. It takes all the flags
that `configure` takes such as `--global` and `--prefix`.

In addition, if any dependencies are not installed it will download and install
them. If can also rebuild packages to ensure a consistent set of dependencies.

Commands for released hackage packages

    $ cabal update

This command gets the latest list of packages from the hackage server.
Currently this command has to be run manually occasionally, in particular if
you want to install a newly released package. 

    $ cabal install xmonad

This is the eponymous command. It installs one or more named packages (and all
their dependencies) from hackage.

By default it installs the latest available version however you can optionally
specify exact versions or version ranges. For example `cabal install alex-2.2`
or `cabal install parsec < 3`.

    $ cabal list xml

This does a search of the installed and available packages. It does a
case-insensitive substring match on the package name.
